Re: [Bug?] TechDraw Dimensions get mixed up after editing the PartDesign model

From TechDraw_Dimension_Length : Notes - All Dimensions are extremely vulnerable to the infamous "topological naming" issue. It is not possible at this time to keep references to 2D (projected) or 3D (actual) geometrical objects in sync with changes in the model. It is recommended that Dimensions b...

[Bug?] TechDraw Dimensions get mixed up after editing the PartDesign model

Hi, I believe there is a problem with TechDraw, which causes some difficulties for me to (re)produce drawings. Namely, editing the model in PartDesign often leads to messed up dimensions in TechDraw. Sometimes, even a save-load cycle is enough to mess up the dimensions, but I was unable to produce a...

Re: [Bug?] Multiple elliptic cuts on different depth levels

Handling OCC's NotDone exception and dealing with zero projected points are separate aspects of the problem, I think. Returning zero points seems to be a legitimate output of the algorithm (ie no exception). NotDone is only raised if the algo actually chokes. So the fix needs to include both the ch...

Re: [Bug?] Multiple elliptic cuts on different depth levels

I'm travelling at the moment, so development time is difficult. Home Tuesday so you should see the fix around mid-week. I'm sorry if I sounded impatient, didn't mean to, as this is a free project after all, in all meanings of the word. I just wanted to make sure that the ellipse drawing issue doesn...

Re: [Bug?] Multiple elliptic cuts on different depth levels

Here is the expected result, achieved with the exception catching patch. I would like to get it added please, because some of the real-word drawings I've made with FreeCAD suffer from these artefacts, and it's very cumbersome to have to patch the executables. Or some other fix for this. The cause is...

Re: [Bug?] Multiple elliptic cuts on different depth levels

Have to confess I'm not a great user of the Iso lines option. But thinking about it, all those extra lines are bound to mess up the drawing of the basic shape and finding the faces among the edges. Probably should be changed to 'overlay' the Iso lines on top of the basic drawing. I don't use the is...

That's great! I can confirm that everything I could test seems to be finally working again!

Re: Recent Change to Selection? maybe Boost::Signals2??

Here is the fix: c3014fc65 Can someone confirm if this also fixes the TechDraw issue? I can't test it myself at the moment. This also fixes both the TechDraw and Sketcher issues for me. Thanks a lot for the fix! OS: Debian GNU/Linux testing (buster) Word size of OS: 64-bit Word size of FreeCAD: 64-...

Re: [Bug?] Multiple elliptic cuts on different depth levels

It turns out that just catching the exception and returning an empty TopoDS_Edge on failure is enough, just like earlier in the same function if there are not enough poles on the spline. So I wrote a minimal patch to catch the exception, this will also fix the bug with just a few changes: diff --git...

Re: [Bug?] Unable to make dimensions in FreeCAD TechDraw

The caller (onSelectionChanged()) is/was already handling selection blocking. The blocking in selectQGIView() is/was superfluous. Also blockSelection()/isSelectionBlocked is internal to MDIViewPage and is concerned more with controlling QGraphicsScene selection signal processing rather than Selecti...
