Problems with nut generation about freecad_fastenerswb HOT 19 CLOSED

Hi f3nix,
This is very strange, I have tried it both on FreeCad V0.15 and V0.16 (5209 and 5332). And it works well. However I use windows version and I have no Linux to test it.
Can you open "Report View" and see if you get any error messages? (View -> Views -> Report view)

There are no error messages in the report view. The console is also empty.

I do not see this problem with FreeCAD 0.14:

OS: Debian GNU/Linux unstable (sid)
Word size: 64-bit
Version: 0.14.3702 (Git)
Branch: releases/FreeCAD-0-14
Hash: b3368125c63289ec8ce9faec2b2ae4c78d436406
Python version: 2.7.8
Qt version: 4.8.6
Coin version: 4.0.0a
SoQt version: 1.6.0a
OCC version: 6.7.0

Any ideas on how to debug it further?

from freecad_fastenerswb.

Can you try it on a clean V0.15 version? (no other plugins/workbenches)

from freecad_fastenerswb.

Also, please delete all preferences: under ~/.FreeCAD, delete (or backup and delete) user.cfg and system.cfg

Hi again shaise,
I've narrowed it down a little bit.

The problem seems to be the OCC version. With OCC 6.7.0 everything works as expected. The OCC 6.9.0 is making trouble...

Hi f3nix,
I'm working with official freecad releases 15 and 16. both are bundled with OCC 6.8.0, which works fine. I'll see if I can easily get 6.9.0 binaries and test it.

from freecad_fastenerswb.

From the picture, it seems that a boolean operation failed, that makes a hex-part from a round part. The release notes for OCCT 6.9 mentions work on boolean operation. The problem could be, that the flat top ring of the nut touches just the cutting shape. I tried to get rid of complex boolean operations, but this one worked and is very fast. So I could try to replace the one complex boolean operation with two simpler operations. For such a simple part, this approach will take a little bit longer. Will see, when I am having some time.

wrote a fix for it:
http://forum.freecadweb.org/viewtopic.php?f=22&t=6558&p=125042#p125042

problem is that shape for cutting hex head is created in a wrong way.

from freecad_fastenerswb.

Yan's fix checked in.
Mateusz,
Can you please test and see if now it works for you?

from freecad_fastenerswb.

Hi.
Sorry for very late reply. Somhow I've missed it.

It works for me now. But I am unable to test with original OCC version this issues has been created with.

I think this issue may be closed.

Thanks guys! :) 👍
