Arch Building Part still touched after recompute

[bernd]

Still there is some problem which might be related to App::link, but may be it is a feature not a bug.

To get the real objects with the real colors the project and site objects needs to be switched off and all buildings needs to switched on. All this has to be done manually. This is really cumbersome especially on huge modells with multiple buildings. It seams the project and the site group have their own shape with totally different colors then the real colors of the objects.

Furthermore if the view is tongled the object is marked to recompute. This is strange for me too.

I also stumbled accross this issue a few minutes before. Even worse, when I do a IFC import of a Site containing some buildings, the Shape of the Site, that is stored inside the IFC file seems to be overriden with the Shape of the building.

I had an file created with an older 0.19 Version before the Link Merge, and the Shape of the site was imported correctly there.

The blue thing in the Screenshot is the Mesh of the site i copied from an older FreeCAD import. With a new Version I couldn't get this shape to display. Only a compound of all the buildings underneath the Site Object is displayed for the Site.

I just submitted a PR for a quick fix

The fix works for me. Thanks for that

But I found another minor issue.
1. Create a Group
2. Add an object to the group. I think it does not matter what object it is. I tested with a simple Part Cube.
3. Toggle the visibility of the group.

Now the Group is Touched but not recomputed. Clicking the recompute button removes the touched state.
It does not matter if one hides or shows the group. It is always touched and not recomputed.

Same here since I heavily use the import of IFC into FreeCAD, but realthunder might not even know what IFC is, thus I used a simple example.

This is actually a 'new feature' for group so that one can obtain a compound shape of the group and use it for modeling. The 'touch' behavior is to make sure the group shape content is in sync. I have made this an optional feature now, and only enabled in App::Part by default. The patch involves quite a few other changes, so may take a while.

@realthunder sounds good to me

This sounds a bit like it would solf the problem @bernd mentioned with the arch site? As it is a group too it might have got the shape syncing logic you describe.

would you drope if you have made a PR?

You mean notify here? Sure. The patch set is mostly about some new behavior of App::Part, but affects plain group too.

[bernd]

... You mean notify here? Sure ...

Yes here. I just would like to give it a try ASAP to give feedback.

any news here. This is still not solved.
