ilogic rule for sheet metal weight

[doug.johnston]

Hey all,

I am just getting into understanding some basic iLogic and now I've hit a wall and can't figure out how to program / place an equation to get the "blank weight" of a piece of sheet metal.

I am linked to an Excel spreadsheet that has the weights I need (lbs/sq.ft & lbs/sq.in.)

I just cannot figure out how to ,or where to put a formula to get the answer into a usable parameter (custom and/or user) in my sheet metal template.

The formula I have tried is: "extents_length x extents_width x WEIGHT_2"   with

extents_length = total length in inches

extents_width = total width in inches

WEIGHT_2 = sheet metal weight in lbs/sq.ft.

I have attached a picture of the user parameters that I have in the template and (2) tries at creating an equation (both as a text and as a number parameter).

Any assistance would be appreciated ...

Hi Doug,

From the error figure you attached, the Unit/ Type should not be Unitless (ul), we need set a valid unit.

If you want to get the value on “BlankWeight_DJ", it is fine to use "ul" as the unit. Please use the iLogic code lines as below -

BlankWeight_DJ=extents_length * extents_width *CDBL(WEIGHT_2)
