GDL - IF using B parameter - Incompatible types

[thomaslodge]

Hi all,

I'm trying to create a GDL object for British gypsum studs but am running into a problem when using IF command to determine another parameter.

So an acoustic stud has a width ( A ) of 42 mm for a stud depth ( B ) of 43mm but a width of 44mm when any other depth of stud is used. I've tried the code below but get an Incompatible types error when I run a check.

How can I get this to work? I also need to do a similar action for gauge which has the added issue of needing to be editable for some stud depths.

Hi

you need to remove the quotation marks in line 51. You just need those in combination with VALUES

It should look like this:

if B = 0.043 then

[...]

Thanks. This worked albeit with a precision error.

eps=.0001 (master script)

if B-.0043<eps then
