Reference Physical iProperties In Parameter Equation

cstarker6VCG4 — Fri, 05 May 2023 20:41:59 GMT

I need to calculate the mass offset of an assembly relative to an axis. How do I reference an iProperty > Physical (Mass, X, Y, etc) in a parameter equation?

I tried iProperties.mass, iProperties.Value("Physical", "Mass"), and just <mass> and had no luck. I didn't find any comprehensive documentation on Parameter syntax, but I'm still looking.

Hi! This will require iLogic. Though you may reference an iProperty within the iProperties dialog, the value is text-based. Parameters are not aware of iProperties. It is the other way around.

It is very straight forward to do it in iLogic. Basically, the rule needs to get the physical properties and then assign the value to a given parameter.

Many thanks!

Attached iLogic file.

Code "borrowed" from example found in this forum.

Unzip and put the file in External Rules folder.

I set it up with Before Save trigger in Part and Assembly.

This is for Mass only.

Do you need location of CoG?
