created solid spheres

[gib65]

I just learnt that a sphere is not a solid. How can I convert it into one (or create one from scratch)? I need it to create a rounded hole (using the subtract command).

How did you create it? If you use Draw>Modeling>Sphere it should be a 3D Solid.

Or REVOLVE a closed profile half circle.

Select the one you have made hit Ctrl+1 to see it's poperties.

Actually, you're right. I made it into an ellipsoid using an autolisp program called scaleaxis (scale along a chosen axis only), and appearantly it doesn't preserve the solidity of the object. I just thought it was the sphere that wasn't a solid to begin with.

Okay, in that case, I need to know how to create an ellipsoid. Would I just create an ellipse and revolve it around its major axis?

Draw a solid sphere and convert it to block. Change the scale factor along the desired axis-it should be an ellipsoid.

revolve half an ellipse...
