Hi again,

I have drawn a sketch and revolved that to create a solid, then created a datum point, added a additive sphere and attached it to the datum point however only the sphere is visible. If I then go to the tree and select the Revolution and set it to visible the Sphere becomes invisible and vice versa if I go back to it and set it to visible.

A PartDesign body describes only one contiguous body. If the first and the second feature don't overlap it is not a valid body and one of the separate solids is discarded. Other features raise an error message in that case.

If you want to model a bearing in a single body it wouldn't work anyway, because it's a single solid. So you could simply make the sphere slightly larger, e.g. by increasing the radius by 0.01mm.

Thanks Crisb. So much to learn, what you describe I think I've read before but forgotten.

Increasing the sphere diameter doesn't have the desired effect.

I'm sorry, could you point in me the direction of how I should model the bearing so it is not a single solid?

Edit: I think I just need to create in a new body. Apologies.

I simple bearing is made up of maybe these.
Ball bearing
inner race
outer race
retainer
clip
Each of the above would be a body. Planning on an array for the balls and a maybe a mirror of the retainers and clips.

Someone last year did a really well detail bearing, you might try to find that posting.

Just for the sake of completeness: it has the desired effect: I have only changed the radius to 5.001:

Thank you again. For some reason it didn't seam to work for me earlier, but I'm guessing that I didn't follow through on it earlier in a correct manner.
