Distance and Coincident constraints in specific dimensions

Question

I need to align a circular object relative to an axis and two planes. I need it to be certain distances off of each of the two planes, but otherwise on axis. In other words, I need it to be a coincident constraint in the X-Y plain ONLY, while it is two independent distance constraints in the X-Z and Y-Z planes. The axis is moving vertically and horizontally as the design evolves, so simply setting things manually via other flat surfaces is insufficient.

Is there a way to specify a specific dimension for coincident restraints in general? Or is there a good way to accomplish this in specific?

I think you have several methods to do this depending on your preferences.

You could create a single part and define all your locations with sketched lines, datum points, axes and planes. This would basically be a skeleton model...especially useful for creating a real assembly later.

You could create a couple of basic objects (Table, Mirror, etc.) and place them in an assembly. Again, create axes, points and datums for positioning.

Hope this helps.

Hi Elliot,I'm having a difficult time understanding what you are trying to express. The figure below is just a sketch on the XY plane. d18 and d19 are completely independant. The circle is on the XY plane, but that can be changed by making a new plane offset from XY. There is a theoretical axis through the center, but you can just as easily create a new axis in that location where the circle is defined as going through it.
