Variable serrations on a flat surface

[NutAce]

Hi Guys....

I need a brilliant idea for below problem.

I have a circular gasket with concentric serrations on a conical part of the surface. The concentric Serrations are varying in pitch and height.
I do not want to model it (makes the model unnecessarily heavy) but I would like to show a detailed view on the drawing. So preferably I would like to use a parametric sketch.

How about 3D modeling the serrations, Then process the 3D model to 2D drafting. Then use Snapshot in Lock view options in the in the 2D view.

Then suppress the steps in the model.

The way it would have been done in the days of drawing-boards , pens and paper ,
draw the serrations in the section view, only.
"Simplified drawings" works today too.


1) create the gasket without serrations. Create the drawing file etc
2) place view on dwg.
3) create section view, without crosshatch. ( Remember in older NX versions to set Extracted Edges = ON to be able to snap the sketch to the model.)
4) create sketch in section view, draw the serrations
5) use view dependent edit to hide the line of the revolved body where the serrations are.
6) insert crosshatch, use Point in region.

Done. (?)

Regards,
Tomas

What I am looking for is a way to create the sketch in a parametric way. Preferably with some Kind of pattern to create the serrations.

sorry, I didn't understand that that was the question.

Can you draw the first tooth, and then use the Pattern Geometry and somehow... scale each instance ?
I do not , at this point, know how to do that...
