auto scale ipart based on another ipart in an assembly

Anonymous — Tue, 08 Jan 2019 11:15:36 GMT

Hello experts,

this question has two parts.

I'm trying to autoscale a part when placing it in an assembly. I can autoscale the part by linking it's parameters to those in the assembly but in this case I would like to scale based on another component.

My specific example requires a square peg to change in width and depth when I imate (?) it to a rectangular hole. The receiving part has a number of rectangular holes so ideally I would not have unique parameters for each of the holes.

Any suggestions greatly received

Hi! Conceptually, there is very limited associativity you can establish between an iPart member and another file (except the iPart factory). iPart/iAssembly was designed to create library components well defined by the author tables.

But, I think you might be able to do so with a custom iPart. Here is the workflow you may consider using.

1) Open the iPart factory file.

2) Create a unitless user parameter called ScaleFactor or something like that and set it to 1.

3) Use Direct Edit command -> Scale -> pick the part -> set Scale factor = ScaleFactor.

4) Edit author table and add ScaleFactor to the table.

5) Right-click on the column -> check Custom Parameter Column.

Now that, the iPart becomes custom iPart. When you place it in an assembly, you can enter a valid value for ScaleFactor and it should scale. You can also use iLogic rule to drive ScaleFactor within the assembly.

Would it work for you?

Many thanks!
