Fusion - Input shape is null

Post by zachjreed93 »

I keep receiving an error for "Fusion002". The error appeared after selecting "defeaturing" option on a feature. Now I am no longer able to cut or modify the main part. This is my first time using FreeCAD so I am completely lost. Project attached.

Any help would be greatly appreciated.

Hi and welcome to the forum!

A recompute fixes the error shown in the tree, But there are more errors, which you see on recompute, e.g. links going out of allowed scope.

I made a test here, which shows that making a union of a Part container doesn't work really well - e.g. you cannot refine it -, you may better use the union on its components instead.

you make fusions with the Part container, then you make another fusion with a component of the Part container: cube 007, it is not possible
by making more logical fusions and Refine = true , it seems to me that the result is good, and more robust
