Rounding the parameters from the userform.

[Anonymous]

Hello community,

I am designing a cabinet which is parametric in widths. The width is a multi-value list and the form has values in inches. However, I want to give my model the value which is rounded in mm.

For examples,

for 18" cabinet, the cabinet width will be 457 mm.

Will an iLogic rule help me to create that?

Thank you in advance.

As long as your "Cabinet Width" Field is not directly feeding the part width, you can just round to the nearest mm at the parameter itself:

Parameter("inch_units") = 18 in
Parameter("mm_units") = round(inch_units / 1 mm) * 1 mm

No. You won't need to use any iLogic.  You can simply create two different UserParameters for the width.  One in inches "Cabinet_Width_in", and the other in millimeters "Cabinet_Width_mm".  Then set the Units of each accordingly.  Then if you want the Inches parameter to be dominant (driving), then within the 'equation' area of the millimeter parameter, put (Cabinet_Width_in * 25.4).  Then it will evaluate the inches parameter to millimeters for you.  In the form, you can change the label/display name of the parameter to eliminate the underscore (_) and the (_in) or the (_mm).  (abs(Cabinet_Width_in * 254 mm)

Hi @J-Camper ,

That was so easy. Thank you for the help.

The Parameter itself wont take a Round function so if you still need to round to a whole number, you can use floor & ceil in the parameter-

floor(MyParamLength) = round down

ceil(MyParamLength) =round up

note: capitalization is important, these 2 parameter functions are not capitalized
