I think I can explain it.
CAD tools are focused on parametric design, meaning you have parameters that effect how the model is shaped.
It’s very useful for creating a product. Let’s say you made an object 10mm too short, and a whole bunch of other features are based on that measurement. If you update it to add 10mm, if you’re using the tool correct, those features built on top will adjust and accept the change.
If you do that in a tool like blender, any feature based off of that incorrect measurement will have to be painstakingly updated one at a time.
So it’s basically a question of “does your design have/need dependancies?”











At that point you’re someone standing next to the dude in the “I ❤️ HP” shirt. Supporting a fandom that is owned by bigots is still not great. At the end of the day you’re perpetuating it’s existence.
It’s not nearly as bad, but it’s not good.
