Can I create a function in NX?

[Kenevil]

Hi,

I created an expression that converts a desired dimension into the closest dimension our 3D printer can theoretically print. This is dependent on a user defined drop down attribute for normal (0.01") or fine resolution (0.007").

Printer_Resolution*round(Desired_Dim/Printer_Resolution)

So this works for one dimension. Can I create a function (or something) that can be used in sketches multiple times with different input values?

Thanks,
Scott

It isn't necessary to adjust your dimensions for your 3D printer's resolution.

Are you looking at reducing the size of the solid body uniformly over the entire body so it fits within the constraint of the 3D printer?

I'm printing mating parts with very small interfacing features. Using 0.1mm clearance for the X and Y usually works fine but I have issues in the Z. I assumed it was because 0.1 is less than half a layer thickness and if the slicer software needed to round it to the nearest layer, my clearance could turn into an interference.

Kenevil --

In a word, yes.

I actually gave a presentation about how to create custom DesignLogic functions (those ones that show up in the Expressions dialog) at PLM World in 2008. The principles and techniques are 100% unchanged since then, so I've attached a copy of the presentation here.

Let me know if you have any questions, okay?

...and here are the example files referenced in the presentation.

Looks like the Forums only allow one attachment per post.

Thanks!
