# Solid Subtraction

## Recommended Posts

This is probably a silly question.

If I create a solid subtraction from an extrude and it has two separate parts.

Can those two parts become two separate objects?

In other words, be able to be selected separately.

Not silly at all.

Not directly.  Here's a couple things to try:

1.  Double click the solid subtraction.  You can now edit the two or more original objects.

2.  Ungroup the solid subtraction. You get the original objects back.

So if you duplicate the current solid subtraction, you can make the subtracted solid in each one big enough to wipe out one of the two remaining parts.

Unfortunately there’s no way to separate the two parts at the moment. even if you convert the object to a generic solid they’ll still be connected. There was a wish list item about this not too long ago.

Yes you can.

Under the modify command "Convert to mesh"  Double click into the mesh so that you are editing 3d polygons.  Delete the random disconnected geometry.    As long is it well-formed, you can then convert it back to a generic solid.

Interesting workaround. Be cautious of this if the geometry has curved surfaces since you will be baking in the polygons the surfaces are converted to in the first conversion.

For curved geometry you might be able to convert to NURBS, delete the extra geometry and then Stitch and Trim things back into a generic solid.

I'd take a look at:
