Help with expression.

james_munro

I am trying to use the expression floor(#xFloor / 406.4 mm) in the instances field of the array tool, but it tells me it is invalid. I tried appending abs() around the whole thing but that didn't help. Please see a screenshot below for clarification.

Thanks!

Try floor(#xFloor / (406.4mm))

That gets me all the time.  I think it helps to think of Neil's expression as

floor (#xFloor / (406.4 * mm))

@james_munro I made a modified version of the Linear Pattern feature which does this kind of thing internally too if you're interested. https://cad.onshape.com/documents/1196579d97167d7a348652a9/w/90798a0a9e5fb98821d253c4/e/3e9783cad47053c2abb99ce0

That works, thanks! I think I just forgot the units.
