How do I capture a **Driven** dimension in DriveWorks Express?

I have a right triangle in the top left corner of the frame I show on the right. I have a fixed dimension of b=1.3"

The 2 angles A & B change and other two sides a & c change depending on the input of the sides of larger frame, H1, H2 and W.

SolidWorks gives me the results of the changes in the large frame but how do I grab those results to use in my formula?

I need to subtract the **Driven** dimension a (.7506) from the hypotenuse of the large frame.

a=(.7506)

(SQRT(((WindowOpeningHeightH-WindowOpeningShortSideB) ^2)+(WindowOpeningWidthW ^2))-.5) -a

Nicole,

I'm not sure, but you might be over-complicating this part.

If you need "b" to be a fixed length (1.300") and the triangle has a right angle, you should be able to handle everything with relations instead of equations.

Here is a quick & dirty sketch (fully defined)

The 1.300" line has a perpendicular relation to the angled line, and it will update accordingly when you change all of the other numbers.

Not sure if this is what you are after, but this is what it sounded like to me.
