Hi all,

I was wondering if it is possible to pull material properties into equations when creating parts, etc.?

For example, say that I have a bar that

- experiences a temperature change of "deltaT" and

- cannot be longer than "L_f"

- a thermal expansion coefficient "alpha"

- has a length "L"

In order to extrude a profile to the proper length, some basic thermo tells us that the bar should be no longer than L = (L_f) / (1 + (alpha*deltaT)).

To do this, I imagine the equations being something to the effect of [numbers are random and don't necessarily mean anything]:

Line | Equation

=====================

1 >> "L_f" = 100

2 >> "deltaT" = 50

3 >> "alpha" =

4 >> "L" = ("L_f") / (1 + ("alpha" * "deltaT"))

5 >> "D1@Boss-Extrude1" = "L"

I'm just not sure how to access the thermal expansion coefficient from the material properties of the part. Any help would be great appreciated! Thanks!
