Simplify Curves

Simplify Curves

Simplify Curves

(OP)
NX 6.0.5.3

I have a profile made up of 130+ small lines. What I need to do is 'simplify' it so that there are less lines (and/or arcs). The simplified profile can deviate by up to ±0.02mm of the original profile.

Any ideas ?

RE: Simplify Curves

The best that could do would be to extract the end points of the lines and then create a spline through the points.  If this is a one-time only task, I suggest that you do it manually.  Granted, it's a bit of drudge work, but...

Now, if this is something which will come up frequently, a simple program could be written to perform this task.

To an Engineer, the glass is twice as big as it needs to be.
 

RE: Simplify Curves

Have you tried using Join Curves?

Insert - Curves from Curves - Join

This will take the curves and join them into a spline.

RE: Simplify Curves

Unless the curve segments are at least tangent-continuous, while the result will be a single curve, it will NOT be smooth.

RE: Simplify Curves

I used a third party gear tooth generator a while back that gave similar results. In order to simplify a series of short lines over what would reasonably be considered a single spline I use join curves to begin with and smooth spline to refit it to a reasonable tolerance. As long as you're willing to split up sections of curves than don't notionally go around corners then it should work for you.
