use relative distance: total construction distance vs diff. from previous point distance.
default would be relative.

Hi,
when trying to create line restricted by distance (e.g. 100km), it creates line which is appeared to be 100km according to CADInput, but is about 50km according to Googlestreets (it covers about half of the road drawn in Googlestreets), project is in WGS 84/ EPSG 3857. Is it really a bug or I just don't know how to use the tool appropriately?
thanks!

I just tried the plugin on a big project (around 40 vector layers), and it is unusable. It takes about 1 sec to display the coordinates.

I believe the problem is in the snapping.

Not sure if it might solve this, but instead of doing 4 snapping, you might want to use QgsSnapper instead of QgsMapCanvasSnapper.
Hence, you should be able to run it only once, and with you proper settings (without changing the project snapping settings).

Here is an example:

    def updateSnapperList(self, dummy=None):
        self.snapperList = []
        tolerance = self.settings.value("selectTolerance")
        units = self.settings.value("selectUnits")
        scale = self.iface.mapCanvas().mapRenderer().scale()
        for layer in self.iface.mapCanvas().layers():
            if layer.type() == QgsMapLayer.VectorLayer and layer.hasGeometryType():
                if not layer.hasScaleBasedVisibility() or layer.minimumScale() < scale <= layer.maximumScale():
                    snapLayer = QgsSnapper.SnapLayer()
                    snapLayer.mLayer = layer
                    snapLayer.mSnapTo = QgsSnapper.SnapToVertex
                    snapLayer.mTolerance = tolerance
                    if units == "map":
                        snapLayer.mUnitType = QgsTolerance.MapUnits
                    else:
                        snapLayer.mUnitType = QgsTolerance.Pixels
                    self.snapperList.append(snapLayer)


   def snapToLayers(self, pixPoint, initPoint=None):
        self.snapping = self.settings.value("obsDistanceSnapping")
        if len(self.snapperList) == 0:
            return initPoint
        snapper = QgsSnapper(self.mapCanvas.mapRenderer())
        snapper.setSnapLayers(self.snapperList)
        snapper.setSnapMode(QgsSnapper.SnapWithResultsWithinTolerances)
        ok, snappingResults = snapper.snapPoint(pixPoint, [])
        self.displaySnapInfo(snappingResults)
        if ok == 0 and len(snappingResults) > 0:
            return QgsPoint(snappingResults[0].snappedVertex)
        else:
            return initPoint

Il y a un commit "do not enable parallel or perpendicular if no previous point", ce qui est une bonne idée, mais ça ne semble pas/plus avoir d'effet dans master.

when using coordinates lock ( x + y ), the added node is not exactly at the given coordinates.

It seems the snapping isn't behaving as expected, sometimes it leaves a gap of 20 m sometimes mm. I have a point layer in WGS84 projected on the fly and a layer in projected coordinates which is the one to which the project is set.

Ability to define a user origin.

If you have several measures taken from one point, you may want to enter coordinates from that point. In current version, the only way to do that is to enter in construction mode between each entered point, which is a bit annoying.

Maybe we could even allow for a user axis...

Would this be useful ?

Hi Olivier,
Are you interested in contributions?
I've some ideas (and little python code) on inquirying, building, editing, etc, of vector features:
have you thought about where to collect contributions from third parties?

Thank you very much, sorry for my bad english, best regards,
giuliano curti

It seems the x,y coordinates on the CAD form interface don't match the ones in the project. It seems they at some point become relative to a certain feature. Don't know if this may cause confusions

When finishing the drawing (right click) qgis-dev crashes

Hi Olivier,

It looks like this tool is replacing the Improved Polygon Capture Tool? If so, my request from that one still stands--it would be great to have the ability to enter angles in the format N45D15'30"W.

Just testing out the plugin, when it is enabled in plugin manager I get this:

An error has occured while executing Python code:

backspace should remove last point

Hello there,

Right-click no longer allows the user to finish digitising a polygon made using the autoTrace tool / plugin.

CadInput seems to hijack the right-click event (it appears to do this around line 180 in CadEventFilter.py). At present, this occurs even when the Enable CAD input button is not toggled.

Please let me know if you'd like more information / data to reproduce and I'll be happy to send something through.

Kind regards,

Pete

Just a minor niggle but the word "parallel" is spelled incorrectly as "parralel".

Thanks for a great plugin.

if you are digitizing a line and click on perpendicular or parallel icons, then when you go back on the canvas the red line from the map tool does not update anymore.

When enable the plugin I can't use the pan pressing the space keyboard

Hi Olivier,
I'll wait when you're ready to TRY to help with (if you are interested in):

• Inquirying (coordinates of the points / vertices, lengths, areas, etc.)
• Diagnostic (points too close, etc ...)
• Building (points at known distances from other points, under angles known from a base, intersections, fillet, trim, etc. ..)
• Linear interpolation (points at absolute or percentage distance along a straight line)
• Quadratic interpolation (arcs, circles, ellipses, partabole)
• Cubic interpolation (Hermite, Bezier, spline, polynomial)
• Editing (coordinates updating by the keyboard, line simplification with the RDP, VW and my own algorithm)
• Transformation (collimation 1, 2 + or 3 points);
  It will need to clean some things already exposed in your plugin or in native functions of qgis;

all the best

Snapping should also occur on features that are currently being digitized...

all in the title ;)

I found weird that finishing the feature digitization adds a new construction point.
I suggest to check if there is a right or left click.

thanks again for this awesome plugin!!!

Don't work block the distance.

When I press the button for block the distance the circle does not remain static

Hi, How to add a CADInput(Advanced Digitizing Panel) to plugin to click when we want to show us a Advanced Digitizing Panel(because I'm trying to make my own toolbar), for example (self.iface.viewMenu().actions()[6]), when we want a Split Features, is any chance to do this, but not to go with View menu->Panels->Advanced Digitizing Panel ?

while digitizing snap at useful angles (45/90) with respect to the last digitized segment or maybe other lines on the canvas

I believe that, as in a maptool, the right click should finish the construction and remove the construction objects.
