I have created an oval extrusion for a sun shade blade. I would like to set an angle parameter so that I can adjust the angle of the blade in the sun shade. I have no problems with square objects where you can align and lock an edge to a reference line/plane. But I cannot seem to figure out how to get curves, ovals, etc... to have paramtric controls for both size and angle. Any ideas? Thanks.

if you can post a drawing illustrating clearer what you desire to have, I can hopefully aid you in getting it. But from your description, all I can say is that with circles and spherical shapes, you have to work carefully with reference planes and reference lines. Thus it is a bit more complex than I can explain here, plus there is a lot of trial and error to begin with. Also, be sure prior to drawing lines and shapes, if you are making a parametric family, build the skeleton first, using reference planes and reference lines. Once this skeleton flexes like it should, then add the skin... I've found this is a little more time consuming, but I have a lot more success following this method (and those that I've trained in my office have to call me less often for help when they follow that concept).

I would like to be able to rotate the oval blades at any angle. In the project that i am working on, we have a sunshade on both the exterior and interior of a storefront system. I cannot use the same type - one of them needs to have the blades in reverse direction. For some reason, I cannot rotate the nested family component (blade). It appears to require a parametric angle assigned to it when you edit the extrusion. This angle can then be changed once the blade family is placed inside another family object. I did set it up to work with just the reference lines/planes but cannot seem to get circular/curved objects to lock onto a straight line. Thanks again.

forget the parametric angle, I tried playing around with it, 45 minutes later, still nothing worthwhile, I'd made this family for our current project as a place-holder until we nail down more what we want, but if you edit my slats from rectangular to oval, just create two different families... one an inside, one an outside, and leave it at that. This is one of those where sure it may be able to be done, and cool if you can, but is it worth the time? It only takes 5 minutes to adjust your slat angle in this family (if that), and it might take several hours or more to make a parametric family.

HA HA - that is exactly what I did! I figured that the time it took to figure this out was not worth it. I made the blade at a 45 degree angle and inserted it into the sun screen. then I rotated the blades to the opposite direction and saved it as a second family. You are right parametric would be cool - but its all about the time. besides this is a custom sun shade we will probably never use again. Thanks for your help. Hopefully in time issues like this can get resolved.
