Simply name the dimensions as you create them, then you can use them in formulas for other dimensions.
If you don't remember the names simply click on the black arrow to the right of the dimension dialog box and it will give you a list of your named parameters.
What I meant to say is that when I'm not in sketch mode, and I need to adjust the height, or width of a support for example, which has different extrusions associated with it, i know about user parameters to adjust height or width, for one extrusion, but how do I add a dimension, outside of sketch mode, which I can assign a user parameter to, that will adjust the height, and move associated objects with it, or is that not possible, and I need to refer back to constraints between different extrusions?
i know about user parameters
I guess I don't understand the question. Are you familiar with iFeatures and iLogic?
Can youi post a file(s) and explain what you want to change.
I was able to get the height to work properly. I assigned a dimension to a sketch, put in 'height', and the other extrusions associated with that part, moved accordingly when I adjusted the height.
I do have a seperate question if you don't mind. I offset a workplane from my leg support, and mirrored that leg support to the other side of the work plane.
How do I adjust the width in between the leg supports? If I delete the workplane used to mirror the support, then the mirrored support goes with it. If I create another workplane perpendicular to the 'mirror work plane', I can only create a driven dimension between the supports.
Any hints? should I have mirrored the support differently?

I have to go do my regular job right now, but I started to work up an example and realized there must be at least half a dozen solutions. Can you attach your real file here - I hate to spend time going through each one of my imagined solutions only to have you shoot each one down.
