Where can I find details of the correct syntax for Math & Trig functions for equations in parameters?

The search found nothing of use. Can you be more specific?

It should have turned up lots of things. Try this instead, I think it might narrow the hits down algebraic operators -- Kent Assistant Moderator Autodesk Discussion Forum Moderator Program "StuartMoore" wrote in message news:31268272.1077559464225.JavaMail.jive@jiveforum1.autodesk.com... > The search found nothing of use.

Search for "cos" in the Help, and Inventor will list the following topics: Edit box parsing example table Edit box reference HTH, Glenn

Thanks for your help but I still cannot get IV to do what I want.
I am trying to create a sphere using the volume to drive the radius. I make a user parameter called SpereVolume and input the volume I want. I am not sure of the units to use here since IV only allows litres or gallons. However, it shouldn't matter if the number is unitless since it is only being used to calculate a radius which has mm units. The equation I am using to calculate the radius is:
=((3*ShereVolume)/(4*pi))^(1/3)
IV's response to this is "Unable to parse equation".

Any ideas would be most welcome.

A further observation: if I replace pi with the numerical value IV accepts the equation but the answer it gives is exaxtly 10x too big and the equation stays red in the box.

OK, I worked it out. Volume must be entered as litres and pi should be PI.
