Change how Parameters work

I can't be the only one this drives nuts... Why can't the parameter system work simply and correctly without having to jump through hoops trying to get units to convert correctly?


Here's a pretty simple example:

Dist = 18.773015 in

Adder = 3.000000 in

Len_Suggested = ceil(Dist + Adder) = 22.047244 in


Uh no... that should be 22.000000 in


Anyhow, to get it to work correctly you have to use:

Len_Suggested = ceil(DIST_HYP / 1 in + LEAD_ADDER / 1 in) * 1 in = 22.000000


Who in the world, by choice, would actually want to write formulas that require you to multiply stuff by 1 in and divide by 1 ul to get the correct answer? How does this make my life easier, Autodesk?


Treat parameter values as simple integers and real numbers during calculation and get rid of all the units junk except for display purposes. That's what almost every other application does (including existing iLogic functions)

I Agree with you, sometimes can be painful.


This is how i use to do. It´s another way to solve the same issue.

Maybe you already know the process, or maybe not... Check it
