Point objects not visible with OCCT 7.6

[drmacro]

This is more just a note, in case others stumble on this.

Starting in the last few days, using the latest pull of FC 0.20 when compiled against OCCT 7.6 (built from latest git from OpenCASCADE) when I create a Draft Point, the point is created (i.e. it is in the feature tree, Properties data looks complete, etc.) but it is no displayed in 3D view.

When it is created the following error is displayed:

Code: Select all

<Part> ViewProviderExt.cpp(1295): Cannot compute Inventor representation for the shape of Unnamed#Point

Using FC 0.20 compiled against against OCCT 7.3 no problem.

Same issue with a Part or PartDesign>Sketch>Point

I can confirm this error. But i can remember, that i used points for while ago. So it must be not that old.

I see this problem on RT's link branch, both daily and stable.

I provided a sample file at the start of this thread:

I can reproduce it with just executing this line:

Code: Select all

Part.show(Part.Vertex(0,0,1))

Works flawless with Debian and OCCT7.6.0, Thanks!
