Problem description

In the image below I added a small rectangle to thew first sketch and I trimmed a couple of edges of this rectangle. FC produced the following error:

Sketch> SketchObject.cpp(11357): cannot find subname ;g86.edge55

After that it was not possible to move the remaining two edges of added rectangle, In this case FC produced following additional errors:

12:00:33 Unhandled unknown C++ exception in ViewProvider::eventCallback (Event type: SoLocation2Event, object type: SketcherGui::ViewProviderSketch) 12:05:54 App.getDocument('planimetria').getObject('Sketch').movePoint(55,0,App.Vector(-264.600341,-11.199707,0),1) 12:05:54 Drag curve: Not able to move point with the id and type: (55, 0)

This is a harmless error which I'll fix shortly. The problem probably happens when you drag the curve somehow lock up the sketcher solver. Is this problem reproducable? I can't seem to do that.

In the last year I encountered very often this kind of problem. I think it started with in may 2023 after the last sync with upstream . Actually this problem can be reproduced without trimming. You may also get this error by deleting the vertical length highlighted in the following picture:

and then trying to move the vertical position of the vertex highlighted in the next picture:

Still can't reproduce the problem. Could you please post the file in the state just before dragging? And also please post your user configuration file.

[wsteffe]

Folowing test file before dragging, user.cfg and an additional image. The problem arise with a vertical drag of the highligted vertex. It happens also when I drag the other vertex belonging to the same horizontal edge.

It is indeed caused by your settings. More specifically your sketcher solver setting as shown below. Mine is 100, which is the default value, I think.

Thanks for spotting the problem. But it is quite strange to me that a smaller number of solver iteration prevented dragging a vertex.
