Base alignment on a round part

[[Gr...]]

I'm really new to all of this. I took the intro course and can figure out how to measure simple flat square parts. I have a round part that I want to measure A cylinder with holes in it . Can't figure out how to do a base alignment on it. You all seem to be light years ahead of me. Help would be appreciated. 😃

I don't know exactly what your part looks like, but If you have the cylinder standing (for example)
vertically, in the XY plane, you can use the cylinder for the spatial (Z+) rotation, and XY origin.
Then a plane for the Z origin.

I don't have light years experience, watch this you tube video series you will get some fundamental Idea in calypso programming. Clark sir already given answer to your question.
Good luck .....

So I have my cylinder standing vertically and I did a base alignment on it and touched off on the features. I used the cylinder for the spatial (Z+) rotation, and XY origin. Then a plane for the Z origin. For the plane, I had to just make a random square on the top of the cylinder for base alignment purposes.
Now for the measurement part. I have holes drilled into the top of it and each hole is measured from the center "0" point which runs through 2 holes How do I line up the "0" point? Do I have to do it manually? I want to do a Cartesian distance between the center holes and the rest of the holes on the top?

I think - better to draw something. It's hard to imagine your needs.

Martin's right - a picture would help.

However, it sounds like you haven't added a planar rotation feature? Measuring one of the holes on top would be ideal for this. If one lines up with the X- or Y-axis, it's as simple as selecting it in the Base Alignment editor. If it's not aligned with an axis, you can still do it, but you'll need to apply one of the transformation under the "Special" menu in the Base Alignment editor.

I need to line up circle 1 and 2 at 0 so I can measure the distance between them and the 4 other circles.

Construct a 3d line from circle1 & circle2, use that for your planar rotation (X+)
Cartesian distance circle to circle.

I feel bad asking this, but how do I construct a 3d line between those 2 features?

Features - 3dline - Option - Recall (Recall both circles)

That was very helpful. Thank you so much Clarke! Now, last question for this part. How do I rotate the part 180 degrees with no clear "0" point and make a 0 point that I can measure from? The last configuration was just connecting the dots with a 3d line.

After the X+ planar rotation, make the large OD X&Y zero (origin)

I had a lot of issues with alignment on part "towing hook" where primary was axis of cylinder and secondary was sphere.

I rather used constructed 3D line from cylinder cut and sphere center as secondary.

I'm not really understanding what to do here. I've only taken the intro class and I am the only person in the shop that has any knowledge of how to use this machine. Sorry. So do I need to create a feature in the center of the cylinder to measure from? How do I do that? Circles 3 and 4 and circles 5 and 6 are equidistant from the center. I'm stuck on this part. I wish I had somebody to mentor me, but instead I have to rely on you guys. Cant wait to take part 2 of training. I really appreciate your help!
