Need to Remove Decimal Precision from Custom Drawing Properties

[Anonymous]

Hello,

So I've created an iLogic template that controls the width of an assembly using custom parameters.  BUT, volume is an important factor in our drawings, so i was able to get iLogic to retrieve the volumes of the individual foams using the following code.

If Pax_Width_Center = "16.3" Then

iProperties.Value("Custom", "Assembly Volume")=iProperties.Value("SPECTRUM BOTTOM CUSHION ASSEMBLY-RECONFIGURED.iam","Custom","Foam Volume-Total")
iProperties.Value("Custom", "Foam Volume-Ethafoam")=iProperties.Value("SPECTRUM BOTTOM CUSHION ASSEMBLY-RECONFIGURED.iam","Custom","Foam Volume-Ethafoam")
iProperties.Value("Custom", "Foam Volume-FPI21ST")=iProperties.Value("SPECTRUM BOTTOM CUSHION ASSEMBLY-RECONFIGURED.iam","Custom","Foam Volume-FPI21ST")
iProperties.Value("Custom", "Foam Volume-FPI55")=iProperties.Value("SPECTRUM BOTTOM CUSHION ASSEMBLY-RECONFIGURED.iam","Custom","Foam Volume-FPI55")

iLogicVb.UpdateWhenDone = True

ElseIf Pax_Width_Center = "17.8" Then

iLogicVb.RunRule("SPECTRUM BOTTOM CUSHION ASSEMBLY-RECONFIGURED.iam", "Pax_Width")
iProperties.Value("Custom", "Assembly Volume")=iProperties.Value("SPECTRUM BOTTOM CUSHION ASSEMBLY-RECONFIGURED.iam","Custom","Foam Volume-Total")

iProperties.Value("Custom", "Foam Volume-FPI55")=iProperties.Value("SPECTRUM BOTTOM CUSHION ASSEMBLY-RECONFIGURED.iam","Custom","Foam Volume-FPI55")
iLogicVb.UpdateWhenDone = True

End If

The code works and the iProperties were able to be imported into my notes block, but the amount of trailing decimal places is way too high; these volumes should be rounded to the nearest cubic inch.  How can I get these volumes to successfully round to the nearest cubic inch, and completly eliminate the trailing decimal places from the paremeters?

Hi t.desrosiers,

See these links for examples of setting the custom property format (assuming the custom iProperty is exported from a parameter):

If the custom iProperty does not come from a parameter, I don't think there is a way to set the precision (hope I'm remembering that wrong), so you might just create a custom parameter and export it to the custom iProperty, and set the precision and formatting.

Also just as a tip, you can search and ask programming questions of this type on the Inventor Customization forum too:

I hope this helps.
Best of luck to you in all of your Inventor pursuits,

Thanks for the prompt reply, but the iLogic code takes the value from the iProperties themselves, which in turn are derived from the model I'm working with. How ever, the ref chart you supplied is a step in the right direction.
