Is it possible to do a TechDraw_DetailView of a TechDraw_SectionView ?

Should be. A missing recompute somewhere?

My recreated document has problems with the detail frame on top:

Snip macro screenshot-7a3bd0.png (16.29 KiB) Viewed 1134 times

It occurs with simple and complex sections. Recompute doesn't change the result

This is the output from the report window:

I hope this helps somehow.

22:04:39 TechDraw::GeometryObject::addGeomFromCompound edgeCompound is NULL

This just says that there are no edges for a one of the hidden/visible/seam/smooth/iso/etc groups of lines. Not a problem, and I think these have been silenced in the latest version.

22:05:04 Geom::asCircle - OCC error - gp_Dir() - input vector has zero norm - while approx spline as circle

are there diameter or radius dimensions in the drawing? This message means that one of the "circles" is actually a BSpline, but that the code couldn't convert it to a circle. Also not a problem except for that dimension.

When selecting TechDraw wb :
22:06:46 MDIVP::onSelectionChanged - unhandled: 4

Something was selected that isn't a vertex/edge/face/dimension/balloon/etc. The selection code only deals with a fixed list of object types.

My recreated document has problems with the detail frame on top:

Recreated? As in not the same file as the one @Shalmeneser posted?

Yes. I wanted to confirm the original issue in a different document to tell if it was depending on the file or the tool, and then have discovered another issue.

[wandererfan]

Can you share the file, please?

Can you share the file, please?

Yes. It was only created quick and dirty and I thought I dumped it already, but it was sleeping on the notebook:

Hatch in Detail View.FCStd

I had added a complex section, too and so it has become a bit overloaded:

Opening the file just above, the Detail view is correct but the circle selecting it is far away from its real target.
And the same is working for my first file.

Where does this vertical offset come from ?
