A better thread title, like "How to draw ball in Inventor" might get you more responses. Most people on Chief Delphi see a thread title of "HELP!" and ignore it, since whoever came up with that probably can't even formulate a good question.

Sketch a 2D circle, put an axis through the centerpoint, and rotate it around that axis. Color it orange if that makes you feel better.

I agree that a better title was needed. I shoot right to the help threads but if every one uses that as a title it gets confusing fast. Also I have to scroll over the title to see what you are actually asking.

And to add to Don's reply, I usually find it helpful to put a tiny flat spot on the sphere to give you a "pick point" seeing as most CAD programs won't let you grab or constrain a tangent point on a curved surface.

I helped you by updating the title to reflect your question and moved it to the CAD forum.

Since you are new around here, I would suggest you take a look at the New User threads and get a feel for the community around here. Oh and by the way good luck this year and congratulations on making it through week one!

I would just create an sphere with an 8" diameter. No need to get fancy

Who's getting fancy here?

If you want to create the black lines that outline the ball for realism there is only one way that I know of to do it. If you create a 2d sketch in a plane outside the ball, you can use any lines from the 2d sketch in a 3d sketch. In the 2d you need to create a u shape that approximates the black lines on the ball. If you then create a 3d sketch, you can project the 2d lines to the surface of the ball and it will wrap around the surface. You can then use a sweep to cut a profile along that 3d sketch.

Once you get the top one in, all it takes us a mirror to the bottom half and you get the fancy curved lines on a basketball.

We just did this in my Design Technology class, it sounds confusing but once you do it it seems really simple. PM me if you get lost and I'd be happy to walk you through it.

I think you can also do it with the emboss function. You draw the basketball pattern on a tangent plane and then emboss it in black, and then mirror it.

Disclaimer: I haven't tried this yet; the only thing like this I've done is raised lettering on a curved bumper shape...
