CAD is a bit like programming, there’s a lot of ways to do any given task. That can make it tricky if you are doing some tutorials that use one workflow, and then start doing tutorials that use a different workflow.

If you want to learn it, do yourself a favor and take time to find a tutorial that goes from start to finish doing the type of project you want to do so you don’t get frustrated when you get midway through.

Like others said, if you are used to doing something in a different CAD software, you might find that the same workflow is clunky in FreeCAD, but if you start out with a workflow that works well in FreeCAD, you are fine.

Seems like a lot of great changes

There’s basically a tree of operations that have been applied to a model. At any point, you can go back and edit what you’ve done at a previous step. For example, if you padded a feature out 10 mm, then added more stuff onto that feature, you could still go back and change that padding operation to 15 mm.

I’m still super new to freecad, and I haven’t done anything too complex in it yet, but my understanding is that some types of those changes can result in the topological naming problem. The way I understand it, when you make a shape, the software numbers all of the segments, vertices, and faces. If later changes are applied to those numbered faces, etc, and you go back and redo the operation that made those faces, etc, in a different order, the numbering will be different, and it will break your model.

There is a fork of freecad that fixes that whole issue, but the fix hasn’t been implemented yet in the main fork cause it’s pretty foundational to the working of freecad, so there’s a lot of things that can break
