How to remove units from reference parameters

[nstalker]

I named a driven dimension parameter so I can reference it elsewhere in my model.  The problem is that the driven dimension is in inches and the reference parameter does not allow me to change the units.  I would like to use that driven dimension in my model and divide it by the pitch in a pattern to get the correct count for my pattern.  The pattern dialog box is expecting a unitless input.

I tried creating a unitless user parameter that referenced the reference parameter but that did not work.

looks something like this

isolate(referenceparameter;unit;ul)

Hi!

Now You have a parameter let's call him "driven", unit: "in"

Now, create a new numeric parameter, choose "ul" as unit

We will call this parameter as: "driven_converted"

To convert use this expression:

Now you can use this "Driven_converted" to use in other parameters.

Remember that:  if you want to use this parameter as a array qty, you will need a integer, maybe you have to add another prefix:

floor(expr) -------- unitless (Next lowest whole number.)                             ex: 2.8 - > 2

ceil(expr)  --------- unitless (Next highest whole number.)                           ex: 2.8 - > 3

round(expr) -------unitless (Closest whole number.)                                    ex: 2.3 - > 2            2.6 - > 3
