Trouble Defining A Circle

[Anonymous]

I'm having trouble fully defining a circle.  I create it, give it a diameter - after that I want to provide a dimension to the edge of the object, but I can't get it to work.  I'm thinking it may be because the object is curved - it does not have a straight edge.

If that is my issue, how does one constrain a circle in that sort of scenario?

Yes, you should be able to dimension, even to a curved edge.  What kind of curve is the edge of the object?  Is it a circular curve as well?  You can dimension between circular edges by dimensioning between the centers.  Or, you can create a construction line to create geometry you can dimension to.

Here are a couple of examples:

Jeff thank you for the reply and the attached video.

My head was spinning and now I am back at it.  I think I resolved my issue, but I am proceeding slowly..

Are you trying to add a sketch dimension or are you trying to turn your 2D circle into a 3D Disc?

Hi Jason,

Thanks for the reply.

I was trying to add a sketch dimension.  I'm chalking up my failure to newbie overload.  When I came back to it a day or so later I was able to add the dimension I needed.
