Revolve a half circle
You also can make a cube and fillet it. Ex. 1in cube and and fillet both sides by .5in
Thank you so much Hardy. It is now days and days that I am trying to do it following the "How to" from the 3D modeling of the Inventor program. It was absolutely unsuccessful and impossible. 2 Errors: "Impossible to build a Revolution"- "The revolution axis cut the outline" Hardy, Your way is so simple. Why Autodesk don't include it in their help menu? amazing. Michel from Brussels.
If You will use center line for create sketch, you won`t select axis. :)
Nice work! Good luck!
Just Revolve the Half Circle......... nd u get the sphere.

I did not know inventor didn't have some basic primatives, what a ball ache if you have to make them all, get IronCad and save some time.
