Draft clone gives an error for Group objects

[bernd]

- start FreeCAD, make a new Document
- change to FEM, make a new analysis (the button A)
- change to Draft
- select the FEM analysis
- click on Draft --> Clone

Code: Select all

Select an object to clone

if it is not possible to make a clone from a Group object this should be cached and at least an error or even better a popup should be printed IMHO.

Furthermore I developed an own object which is based on ArchComponent. If I try to clone this the following error comes up:

Furthermore I developed an own object which is based on ArchComponent. If I try to clone this the following error comes up:

It works on Python if forcedraft is set to True. But this should be catched too. There hopefully will be more ArchComponents in the future which are not part of Core Arch FreeCAD ...

Furthermore if the solver object of an FEM is cloned the same error as for a Group object comes up, because these kind or objects neither have shape nor a placement.

trying to clone an Arch Material results in :

Ok all these issues should now be solved in git commit 0d4106541. But cloning an object with no shape (groups excepted, which are supported) has not much sense, since the clone essentially duplicates the shape...

FullACK no sense at all, but catching them makes sense anyway. I got the error on the own ArchComponent and just was playing around a bit ...

works great
