Hello there,

I am needing to create an upper corner cabinet that flexes.  The depth is set to 13" for each side so it lines up with wall units on either side.  I need this depth to be parametric.  I have the frame of the cabinet working, however I cannot seem to get the parameter for the 45" angled door to flex with it.  I've tried several different Square root formulas using A^2 + B^2 = C^2.  The calculations work, but don't equal the right length.

Does anyone have a simplier way to get this working?

Thanks,

LJ

Flexing angled lines and extrusions requires the use of reference LINES, not reference planes. I got rid of the model group of ref planes which you don't need (and also the void extrusion which just requires more computing power and provides no benefit), and used several ref lines and new parameters to make the door and the front of the cabinet move. The ref line at the BACK of the cabinet, nearest the wall, is aligned and locked to the vertical and horzontal ref planes which it touches. that allows you to add a labeled dimension (I called it Depth 2) between that ref line and the diagonal line to which the front of the cabinet and the door are aligned.  I locked the thickness of the door at 3/4" in the sketch so it wouldn't deform when the front of the door moves and added an offset parameter with a formula for the handle. You can change these as you like, and I'm sure you'll want to add another formula to determine Depth 2. Better than a formula, define the types you need and just put the correct Dept 2 dimension in the value field for each type.  This should get you on your way. I had to do this in R2010 because I don't have an earlier version and I noticed it upgraded when I opened it in 2010, so I hope you are able to open it!
