Algebraic operators not working in "Change Parameters" dialog boxes

[Anonymous]

I'm running on a Mac with High Sierra and Fusion 360 version 2.0.3803, But I can't put an equation into the "Change Parameters" dialog box. Simple ones work (e.g. r+2), but I want pi*r^2, and can't even get r^2 or r*r to work. I think that "pi" should be a constant, looking at the examples online.

Any Ideas?

Hello @Anonymous

I don't think we have a 'pi' as constant. You may create a parameter named 'pi' = 3.14 (or more digits according to need)

As far as r^2 or r*r is concerned the problem is that for example if you have a parameter of units 'mm' and you are trying to set it as mm*mm for example

r = 5 mm

Param1 (mm) = r*r

This will cause issues because r*r is mm^2

You can solve this by simply putting

Param1 (mm) = r*r/mm

Is this the case you are running into?

I might be able to help in this case to solve it.

Thank you,

Yes, that fixes the problem. 

Thanks so much for your help.

Here's another example for your PI*r^2 problem
