Non Manifold Body

[Josh Rayburn]

Can anyone explain exactly what a non-manifold part body is?
Thanks in advance,
jnr

Josh,

This is an explanation I found on the internet and it makes sense.

Manifold is a geometric topology term that means: To allow disjoint lumps to exist in a single logical body. Non-Manifold then means: All disjoint lumps must be their own logical body. Of course that definition is often more confusing so perhaps the best way to think of Manifold and Non-Manifold is this: Manifold essentially means "Manufacturable" and Non-Manifold means "Non-manufacturable". In other words manifold means: You could machine the shape out of a single block of metal....and with a non-manifold shape you could not.

Josh,

Is there a specific cabinet or job file that is causing you to ask this question? If so, please post it or the instructions for how to generate this error.

Also, Kerry, excellent description for the manifold bodies. That is a hard one to describe.

I also get this error when trying to profile anything in the part editor
