Found a case.

It would be better if you provide an example file; often the model has modelling problems and that causes invalid shapes. Hmm... I'm trying to find the file where I saw the problem, but can't reproduce it. I've used many old tutorial files, which probably were created with some old or custom build ...

for obj in App.ActiveDocument.Objects: if obj.isDerivedFrom("PartDesign::Feature"): print("It's a feature") Thanks, I will try that. Looks like that's exactly what I need. However, I'm not sure what you want to do. For an exploding assembly you would need to move entire Bodies, not the individual f...

Hello All, Is there an easy way to identify a visible part of an object in python? I'm trying to implement explode feature for Assembly4 and need a way to traverse other sub-objects and find a visible part/face. I thought to filter the objects using their TypeId, but now I realize that I have to tak...

Teaser for work in progress feature...
Original part: Exploded:

Open a test assembly4 project (I used example2 with crankshaft). https://github.com/Zolko-123/FreeCAD_Examples Right click on any linked object in the tree view. Select "Send to Python Console" from the context menu. Python console will execute a command that will assign the selected object into "ob...

A bit more data: Commenting out the following code block from the ViewProviderDocumentObject::show() function cuts the execution to 0.02-0.03 seconds every time, while the functionality still works fine (at least the 3D view gets updated). // use this bit to check whether 'Visibility' must be adjust...

Hello All, I've implemented a feature of show/hide some objects for Assembly4 in Python. The implementation requires to traverse over all the objects in the document tree and show/hide the needed ones (LCSs). I have a model with few hundreds of such LCSs, while traversing over the objects I set Visi...

Looping on all the rows is a workaround, it's not a spreadsheet API...

Hi, I might be missing something, or there is no such API? Here's my situation: I add some rows to the spreadsheet in python with set function. All works great, the alias helps to find the data I need in the document. The problem starts when I need to add more rows to the document... Can't find any ...
