Hi, i try to test your module but i cannot understand how to lunch...
I install "CadQuery" from https://github.com/dcowden/cadquery

I try to lunch "cq-ex2.FCMacro" (it's reside to my .Freecad/Macro but it's same if i try to lunch directly from your directory) and i receive this error :

Traceback (most recent call last):
  File "/home/hpc66-jo/.FreeCAD/Macro/cq-ex2.FCMacro", line 23, in <module>
    App.setActiveDocument("Ex000_Introduction")
<class 'Base.FreeCADError'>: Try to activate unknown document 'Ex000_Introduction'

Can you tell me how to use your script please ?

thank.
Jonathan.

Hi @easyw

For my recent models, I developed a Python class called Ribbon.

https://github.com/hackscribble/kicad-3d-models-in-freecad/blob/master/cadquery/FCAD_script_generator/Molex_55560/cq_models/ribbon.py

It let's me define a complex line as a series of straight line segments and arcs of given angle and radius, and then turns this centre line into a constant width closed wire (which can then be extruded to form a device pin or contact, for example).

Is this the sort of thing that might be added to the _tools folder, either as a standalone file or added into cq_helpers.py? If so, I will raise a PR.

Thanks

Example of use:

I am trying to add new models to the generators. Unfortunately the scripts referred to in the documentation files don't exist. (Like for example make_gw_export_fc.py) running the main_generator.py scripts that exist inside the deeper directories don't really work, complaining that it can't find the CadQuery module that is definitely installed in my freecad installation. Trying to push this further I ended up with errors complaining that exportVRML module is not present.

I wish to be able to contribute more content to the KiCad 3d models but not being able to figure out how to run the generator scripts makes it very difficult. :(

Maybe there should be a top level make file that generates all the models as every other software project that is expected to run on linux is built? Or at least a toplevel shell script that is tested on the most mundane and wide spread Ubuntu LTS installation with the default FreeCAD V0.15 and CadQuery installed using the addons_installer.

As a sidenote: Getting that far is already a hugely cumbersome process that requires a multitude of steps to reach, if you want more contributors you will definitely have to simplify this. :(

Hoping I could contribute some additional scripts. Promise to be tidier than the IDC headers this time! Let me know what you need next and I'll have a crack. Otherwise will be doing one to generate some TO92s (which were missing from my last project...).

See KiCad/kicad-packages3D#177

I have only tested the BGA generator script for now but it is failing with the "missing CadQuery 0.3.0 or later module". That error is generated despite CadQuery being installed. The actual offending line is from Gui.Command import * but it is included in the same try catch block as the CadQuery import command.

This is the offending line: https://github.com/easyw/kicad-3d-models-in-freecad/blob/master/cadquery/FCAD_script_generator/BGA_packages/main_generator.py#L108

Tested with freecad V0.15, V0.16, V0.17 and in all of them this script fails.

Hello everybody,

I'm using CadQuery and the script /LED_SMD/main_generator.py for the first time. I'm starting the script by calling freecad-daily ./Downloads/FreeCAD/kicad-3d-models-in-freecad-master/cadquery/FCAD_script_generator/LED_SMD/main_generator.py LED_0805
FreeCAD is starting and I'm getting the following error message Exception while processing file: ./Downloads/FreeCAD/kicad-3d-models-in-freecad-master/cadquery/FCAD_script_generator/LED_SMD/main_generator.py [No module named exportPartToVRML] File format not supported: LED_0805

Could you please tell me what I'm missing? Thanks a lot!

Fixed for Inductor SMD with this Commit

While fixing the Buzzer_Beeper generator in order to work with FC 0.18 (see PR #374), I found that it works in FC 0.17 fine, but when running in FC 0.18, the program freezes (black screen) and nothing else is displayed.

I have tried to apply typical python3 fixes using 2to3 as well as other manual fixes but none worked (see my last commit here with the fixes I tried).

I can't debug this due to FC 0.18 black screening and not showing any exception/error messages - does anyone have any other ideas of what might be causing the behaviour?

It have a feeling that it might not be a python2/3 compatibility issue and instead some sort of issue with FreeCad python API?

Steps to reproduce:

1. cd cadquery/FCAD_script_generator/Buzzer_Beeper
2. start "" "C:\Program Files\FreeCAD 0.18\bin\freecad" main_generator.py MagneticBuzzer_CUI_CST-931RP-A

I'm trying to create pin headers with your script (c:/freecad/bin/freecad make_pinheaders_export_fc.py all). But FreeCAD just gives an error message:

./generated_pinheaders/\PinHeader_Straight_1x02_H06_p1.27mm.step
./generated_pinheaders/Exception while processing file: make_pinheaders_export_fc.py [local variable 'LIST_license' referenced before assignment]
File format not supported: all 

and only created that one .step file. What am I doing wrong?

And a second question, is it possible to create angled pinheaders?

Some packages have their pickup point for pick and place machines not in the center of the footprint but shifted by an offset. I think at the moment it is not possible to generate 3D packages with this requirement. At least for the Converter_DCDC script but I haven't found this functionality in other scripts either.

KLC F6.2 says that the footprint anchor should be placed at the pickup point and KLC M2.2 tells that the 3D models must be placed with an offset of (0, 0). This means that the 3D model needs to be shifted in the python scripts.

I can imagine that this is not too difficult when the coordinate origin is shifted by the specified offset but I have no idea how to perform this in FreeCAD therefore, I will leave this task to someone else.

Murata's NXE2 series is an example where this is necessary:

Is this an issue with CADquery?

One question, is there already a script for generating the 3D model of SM series resistors, see here: https://www.te.com/commerce/DocumentDelivery/DDEController?Action=srchrtrv&DocNm=1773242&DocType=DS&DocLang=English

Or is one easily adaptable for this purpose?

Thanks in advance.

Suggested:
freecad kicad 3D

The models for the SW DIP seem to have been exported rotated around PIN number 1 of the component.

Sorry I cannot find the time to guess why I cant execute the scripts with my version of FreeCAD and CadQuery.

Can anyone have a look at this?

@easyw from time to time we get people that seem to reinvent the wheel. I fear this is because they do not realize that your cadquerry/freecad scripting tools exist. (Similar problems exist for the footprint generator scripts.)

It might be a good idea to at least include a pointer to the cadquerry directory in the packages3d-source repo. The credits files in the packages3d repo alone do not seem to be enough (New contributors adding new models do not seem to look how the existing models have been created). I am not so sure a note in the Readme will help much. (If you want more time to think about this we can do this in the meantime)

We can include the FCAD_script_generator part as a git submodule. But this would require a fork that only contains this one directory. (Sadly git submodule can not point to subfolders in the source repository. There are unofficial git extensions but i do not assume library contributors would be able to use them.) It would also require that contributors know about git submodule. So maybe not the best option.

Another option would be to "move" that one folder over to the package3d repo. To keep you as maintainer of this little corner, we could give you collaborator status of the kicad-packages3d-source repo. (Of course only as long as you wish to keep maintaining this.) If we choose this option i would try to get the git history across as well.

A third option would be that the kicad team holds a fork of this repo and we point users via the repo description to the fact that your repo is the maintained repo.
I bet we will get pull requests on that fork.
Maybe it is possible to have some automatic script that syncs up the kicad fork with your repo on a regular basis. This would make it easy for contributors to just simply open a new PR on your repo with the same changes. We can even add a note to the pull request template that points to your repo.

Hi @easyw and @Shackmeister

I've opened this issue to continue the discussion from the PR ... #49

I'm adding Shackmeister to this conversation...
He did the work to extend sot packages to many asymmetric models and he was suggesting me to improve the generation for other models - @easyw

I was considering adding and option to set each pin induvidualy to either a GW or a flat pins... also I was thinking about adding an option in exclude_pins to set a value to 2.5 to only have half of the pin. would be used for TO-252 etc. - @Shackmeister

Can you confirm that the existing scripts are in this folder?
https://github.com/easyw/kicad-3d-models-in-freecad/tree/master/cadquery/FCAD_script_generator/GW_QFP_SOIC_SSOP_TSSOP_SOT

Thanks

I'd like to generate the 3D packages with main_generator.py script(s). Later on, I'll generate my newly created parts the same way. Unfortunately, the scripts fail with:

C:\Common\FreeCAD-0.17\bin\python.exe main_generator.py
FreeCAD 0.17, Libs: 0.17R13541 (Git)
Traceback (most recent call last):
  File "main_generator.py", line 64, in <module>

    clear_console()
  File "../_tools\exportPartToVRML.py", line 93, in clear_console
    mw=FreeCADGui.getMainWindow()
AttributeError: 'module' object has no attribute 'getMainWindow'

Then I realized that I have to call the main_generator.py script(s) with FreeCAD rather than with python. This is not documented by the way.

Afterwards, the FreeCad GUI is poping up the the conversion starts.

During my search regarding to the getMainWindow error I found the documentation about Embedding FreeCADGui. Especially the section Without even firing up the FreeCAD Gui was quite interesting to read. Maybe, this is an option for the future.

Hi @easyw I have written a CQ script to generate the 3D models for a TO-220-7Lead_TabPin4 SMD device (aka TO-220-7-4). It is a "standalone" script to be run from the CQ workbench in FC - it does not use the main_generator.py framework.

In kicad-3d-models-in-freecad/cadquery/FCAD_script_generator/, should I create a folder just for this script or create a generic folder TO_SOT_Packages_SMD to match the .pretty folder in the KiCad library?

Thanks

I extended the SSOP generator script to include an SSOP-18 variant, see #173.

Now after proposing it for inclusion in KiCad/kicad-packages3D#320, I noticed that the first pin marker (circle) is missing in the generated FreeCAD model.

I've had a quick look at the source code for main_generator.py, but could not find an obvious reason for it to be missing. There are some commented-out lines, though. Maybe my rather recent FreeCAD version (compared to what some of the READMEs talk about) could play into it?

Hi @Shackmeister and all developers,
I've just updated the 'cq_cad_tools.py' adding two new functions:

1. checkUnion(doc)
2. checkBOP(shape)

and a source file to run these functions (I included all the functions in the file so to be able to run it easily)
checkBOP-example.py
I attached here also a wrong STEP model, not correctly union-ed and with wrong geometries to make some tests.
resistor-wrong-BOP.zip
uploaded also on the repo...

It is suggested to generate/export a STEP model, then close the file generator and import the STEP file;
then run the checkUnion function to see if the STEP file is correcty union-ed in a single part and run the checkBOP function to see if there are errors on the STEP shape.

This is going to be a quite robust check on the generated files... still in some case I found BOP check is not perfect, but it is for sure much better than the previous state.

Requirements:

• FreeCAD 0.17 12703 or later

Hi Maurice, I'm having troubles getting the script to work in this new computer. I think I was using freecad 17 last time but I couldnt find that version so I'm stuck with fc18.

I'm getting this eError string: "CQ 030 doesn't open example file"

(sorry, can't figure out the shared clipboard on this VM)

I have the latest cadquery from the addon manager, a fresh ubuntu install, yaml is installed from pip3.

Not sure what else I can try...

Thanks!

@easyw, @SchrodingersGat, @Shackmeister, @DASFrank, @metacollin:
How should the generators be organized.
For me 3 options come to mind: (sorted from most effort to least effort.)

Option 1:
Go for depth

Option 2:
My current effort. A bit of depth but also a lot of directories in the root folder.

Option 3:
Focus on a uniform repo
Effort by Oliver (as i understand it. I might have interpreted it wrong.) This is the solution that creates the least amount of work.

I vote for option 1 because i think it is the most future proof. (It will work even if we have 10 times the current generator scripts.)
Option 2 generates nearly the same amount of work as option 1 does. (Still has a cluttered root directory)
Option 3 could be a quick and dirty fix to get a uniform repository.

Any other suggestions?

Dear all!

Firstly I don't know how to get in touch with you apart from this GitHub issue section. I apologize if you don't like it this way.

I used KiCad to convert a STEP 3D design to a flat KiCad PCB footprint as explained in this tutorial (generating a kicad footprint from a 3D STEP model - YouTube). I got issues at the last step, which is the final export to the kicad_mod file. Either FreeCad uses too much RAM and my PC crash, or I get a Python fail Traceback. The console prints are copy-pasted below for your debugging.
The STEP file I wanted to convert can be found here (link to the download).
Versions used were: Windows 10 19041.928, FreeCad 0.19, KiCadStepUp installed via FreeCad addon manager today (23-04-21).

Does one of you know what could be my mistake seen the Traceback below?
On the other hands, I would be really happy if someone could help me converting this STEP to a footprint ;-).

Yours faithfully,
Cyril

I'm very new to this script so this might be a non-issue and just me being stupid...

I am on Windows 10, FreeCAD version 0.17 and cadquery_module installed from within FreeCAD.
I have opened command prompt and navigated to cadquery\FCAD_script_generator\QFN_packages and run below two commands:

taskkill -im freecad.exe /f

start "" "C:\Program Files\FreeCAD 0.17\bin\freecad" main_generator.py QFN-16-1EP_3x3mm_Pitch0.5mm

When FreeCAD opens I get below error message in the FreeCAD console:

QFN-16-1EP_3x3mm_Pitch0.5mmException while processing file: main_generator.py [global name 'math' is not defined]
File format not supported: QFN-16-1EP_3x3mm_Pitch0.5mm 

Is this some bug or is my configuration incorrect?

JST connector series is widely used and lack support in these scripts. My main use cases are :

• SH Series connectors which are SMD only
• SMD vertical and horizontal variants of other series connectors.

SH series should be a good point to start from scratch on SMD variants and this variant scaled up with similar geometry but different parameters to other series connectors.

Hi, I don't know if its this the right place to report.

When try to open new footprint it shows the pad as circle, instead of a square with rounded corners.

I'm using freecad 0.17 with StepUp version 7.3.3.1
footprint tested: link

Thanks

Hi

What did we say a while ago, was we promoting ".yaml" or "cq_paramter" fileformat format ?

I was looking into "cadquery/FCAD_script_generator/LED_SMD" and it is yaml based regarding push
KiCad/kicad-packages3D#554

Hi,
I was trying to use thist tool to generate a 3D model for this PR:
pointhi/kicad-footprint-generator#452
Which matches the OnSemi Case 506AQ.

I realized that it is already generated with correct exposed pad size if I run "freecad main_generator.py DFN-8-1EP_2x2mm_Pitch0.5mm".

However, Kicad needs a 3D model named as DFN-8-1EP_2x2mm_P0.5mm_EP0.7x1.3mm .
Therefore, what should I do to generate this model (and request a PR afterwards)?

TIA

https://pythonclock.org/
Looks like (all of?) this is python2. Can it be migrated to 3?

Hello Easy

What is the correct most up to-date form of 'main_generator.py' ?

Actually, the molex is good. All the stuff in is clearly separated between drawing the models (imports CQ_models) and the creation/opening of files, licence, Gui etc...

Is it possible to move more of the code found in main_generator.py to something in _tools ?
A something that will callback the code to build what is wanted ?

main_genrator.py:

from cq_tools import savemodel

....
import my cq_models
....
def export_one_part (module, pincount, configuration, log):
      ....
       #gen a single model based on our data
       cq_obj_data = module.generate_part(pincount)
       
       #let 'tools' take care of boring stuff
        savemodel (cq_obj_data, module, pincount, configuration, log)

  def exportSeries(module, configuration, log, model_filter_regobj):
    for pins in module.series_params.pinrange:
        try:
            if model_filter_regobj.match(str(pins)):
                export_one_part(module, pins, configuration, log)
        except GeometryError as e:
            e.print_errors(stop_on_first_error)
            if stop_on_first_error:
                return -1
        except FreeCADVersionError as e:
            FreeCAD.Console.PrintError(e)
            return -1
    return 0
    .....

The 'configuration' can take care of all specifics like filenames, etc etc.
Is it correct to think that (not doing it today of course !) ?

Hi everyone! Several weeks ago i started contributing to KiCad/kicad-packeges3D and created some 3D files with FreeCAD Part Design. In the discussion of my last PR KiCad/kicad-packages3D-source#293 i understood that a more efficient way is to use the CadQuery scripting. Thereupon i started to get a little bit deeper into this matter and worked through all the examples of CadQuery. But when i tried to understand/run the scipts in this (easyw/kicad-3d-models-in-freecad) repository i got a lot of problems. I could not run any script in FreeCad without getting errors and the same result i get when calling the scripts from the corresponding dir (e.g. DIP_Parts)

...\bin\freecad.exe main_generator.py DIP-10

It gives following exception in FreeCAD:

Exception while processing file: main_generator.py [Missing parentheses in call to 'print'. Did you mean print("CQ 030 doesn't open example file")? (cq_model_generator.py, line 120)]

The only success i had with the example file cq-ex2.FCMacro. This file runs without any problems.

Can anybody give some hints what's going wrong and what i should do to contibute to kicad-3d-models-in-freecad repository sucessfully.

pointhi/kicad-footprint-generator#55

Sounded like it could be useful, 3d models were mentioned. Might be worth mcad people following / taking an interest...

Anyone think it's a good idea to share the same input data for footprints and 3d packages (at least for the scriptable / standard kind of components?).

I was trying to add a 3D model for AVX M620720 antenna, using the following diff: diff.txt
Datasheet: http://datasheets.avx.com/ethertronics/AVX-E_M620720.pdf

If I uncomment the epad line, I get the following error:
Exception while processing file: main_generator.py [BRepSweep_Translation::Constructor]

Can anyone help me to know what's wrong with this line?

Thanks,

According to the README files the scripts should be working with the stable version of freecad that is the default version in Ubuntu aka V0.15.

But cq_cad_tools is checking and trowing an error if the version of freecad is less than V0.17.
https://github.com/easyw/kicad-3d-models-in-freecad/blob/master/cadquery/FCAD_script_generator/_tools/cq_cad_tools.py#L655

You should test the scripts on V0.15, and handle that gracefully unless you want to force everyone who would like to contribute to install developer version of freecad.

Don't ask me why they have this problem. If we encode the dot as %2E it works in catia.
(What really makes this strange is that only one dot seems to be troublesome. Only the one between 4 and 0 of the creative commons site.)

Has anybody else encountered strange problems with comertial step file parsers?

I was working on a new DC to DC converter model but the generator no longer seems to work. Using commit fb2c76a of this repo, running command:

'C:\Program

I was wondering if there is any reason why there are no metric fuses included in the kicad 3d model libraries.

For example, C0402 is generated, but not Fuse0402. Maybe they could be included, giving them a different color? (blue or green)?

@poeschlr I'm currently going through the models and was planning to fix the library names of the phoenix connectors. I do however have some troubles with running your script, can you please check if you have some uncommited changes?

I am trying to model a Vishay/Dale CP0003 resistor (https://www.vishay.com/docs/30213/cp.pdf) using the following cq_parameters.py entry:

'CP0003': Params(
        body_color_key = 'white body',
        pin_color_key = 'metal grey pins',
        l = 22.22,
        d = 7.94,
        w = 7.94,
        pd = 0.914,
        px = 31.75,
        py = 0.0,
        shape = 'box',
        orient = 'h'
    ),

The resulting model has no lead bends nor lead stubs coming out of the body:

Is there some known and minor fix so that the leads come out properly but the model is still representative of this resistor?

I guess this is a limitation of the script, and different argument values will generate proper leads. If the arguments given are known to produce invalid results, it might be nice to alert the user at a minimum. Preventing model generation would be something else to consider, but certainly alert the user (especially since there isn't a preview for this script like the CP_Radial_THT script) as there's no quick and easy way to see there is a problem during model generation.

In addition, you may notice that the body color isn't very white. I found that other colors work well, and since the color looks more white in PCB design software I suppose this is an issue with FC or a misconfiguration of FC or my PC that is my fault. So I don't think there's anything to do about it, but I mention it just in case someone happens to have some ideas and takes the time to share them with me here.

In general, this script doesn't seem to have good error handling or input sanitation. While I was experimenting with various shapes to see what they look like, it wasn't always obvious what parameters were required for each shape (if zero is acceptable or not). It would be helpful to check the arguments based on the shape type and let the user know what's wrong. That all being said, a working generator that does it's thing nicely with a little trial and error is infinitely better than no generator at all!

I'm trying to add an inductor, http://katalog.we-online.de/pbs/datasheet/74435580680.pdf

Would it be the correct approach to add it to FCAD_script_generator\Inductors_SMD?

The available parameters are:

Params = namedtuple("Params", [
'L', # package length
'W', # package width
'T', # package height
'pb', # pin band
'pt', # pin thickness
'series', # Inductor Series
'modelName', # modelName
'rotation' # rotation if required
])

For the inductor in question I would need to remove the pb parameter and add pin length and width.

Adding new parameters breaks the existing models that are already in the script.

How would I modify the script without breaking the existing models?

Running main_generator.py gives missing CadQuery message but the program (and other generators) work OK.

Fixed by adding import FreeCADGui as Gui to program.
