Did you check to see if bug exists already ? https://github.com/FreeCAD/FreeCAD/issues?q=state%3Aopen%20label%3A%22Mod%3A%20Measurement%22

Can you zip up an example file and drag/drop it into Github textbox ?

Sure. I noticed it crashes when "Length" is selected and not when "Distance" is selected.

For me, it happens when I press reset and start a second measurement. Auto is on and it auto selects distance and crashes or gets stuck on the measurement task panel every time. From there you cant save or close the task panel.

This happens to me too. I noticed that in the 1.1 weekly build, the tool resets the metrics when you click on a blank space, whereas in the 1.0 build, it didn't. Could this be related to this bug?

It happens to me too. I can confirm this in 1.1.0dev Linux amd64 and arm64.

More specifically, my experience is that FreeCAD crashes when the item(s) selected for measurement are deselected - i.e. when clicking on the side to deselect them, pressing ESC or clicking on Reset.

However, I found a workaround: in the Measurement settings (small icon on top of the Measurement task tab), if Additive Selection is enabled, FreeCAD doesn't crash anymore.

@Giraut can you please add you full About info for each instance you tested on ?

luzpaz avatar Jun 16 '25 13:06 luzpaz

I've tested https://github.com/FreeCAD/FreeCAD/pull/22016 with regard to another report on the forum and I cannot get a crash. The title regarding PartDesign is irrelevant to me, it's any 3D object IMHO.

I can confirm that it is not working properly. The problem occurs when two vertices are selected:

09:16:00 <Exception> Access violation 09:16:00 0 Selection.cpp(158): Unhandled Base::Exception caught in selection observer:

Tested also in safe mode.

FreeCAD crashes if I select two vertices with the measure tool. If I select and deselect shows warning about unhandled exception.

Below is the backtrace and the about info.
