Macro does not work

[HKaufmann2]

I created a three-part assembly on Linux-Mint 22.3 with FreeCAD 1.0.2 Assemply 4.

When calling the macro over the toolbar, FreeCAD hangs up and I have to close it forcibly.

The macro does not start at all using the STR+Shift key combination.

Thank you for your report but which macro are you talking about. Please provide us with an example of file to test with.

"The macro does not start at all using the STR+Shift key combination" this is another issue. This repository doesn't offer any way to install and launch macros. If you installed the macro via the Addon Manager, please report any installation issue there.

It's about the Macro CenterOfMass. At startup, this window appears:

10:12:35 Loading CenterOfMass 0.8.4 ... 10:12:35 Looking for material cards according to User parameter:BaseApp/Preferences/Mod/Material/Resources 10:12:35 /app/share/Mod/Material/Resources/Materials/Standard 10:12:35 /home/hkaufmann/.var/app/org.freecad.FreeCAD/data/FreeCAD/Material 10:12:35 Select a valid object (a solid or a mesh) first. 10:12:46 Traceback (most recent call last): 10:12:46 File "/home/hkaufmann/.var/app/org.freecad.FreeCAD/data/FreeCAD/Macro/CenterOfMass.FCMacro", line 310, in on_startup_dialog_finished 10:12:46 objs = self.valid_selection(gui.Selection.getSelection()) 10:12:46 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 10:12:46 File "/home/hkaufmann/.var/app/org.freecad.FreeCAD/data/FreeCAD/Macro/CenterOfMass.FCMacro", line 764, in valid_selection 10:12:46 o_.Placement = o_.Placement.multiply(it.Placement) 10:12:46 ^^^^^^^^^^^^ 10:12:46 AttributeError: 'TechDraw.DrawProjGroup' object has no attribute 'Placement'

If I choose what happens nothing.

I would need the corresponding assembly (.FCStd file) to see how it managed to pass the valid selection check.
Please be aware, however, that I do support only the internal Assembly system, no external workbenches like Assembly4.
Workaround: Do not select the TechDraw drawing in your macro instance.

[HKaufmann2]

Use Assembly 4, because the internal assembly is too unstable, since the TNP (Topological Naming Problem) has not been solved correctly yet.

Please check whether the issue persists in latest stable FreeCAD with CenterOfMass macro version 0.8.7.

In the new FreeCAD version 1.1.1 it works. Why not in 1.0.2?
