Converting sketch to lines and arcs.

Converting sketch to lines and arcs.

Converting sketch to lines and arcs.

(OP)
Hi all. What is the easiest way to convert a sketch to un-parametrized lines and arcs? I have to be missing something. Right now, I'm copying the sketch curves to another layer and then deleting the sketch.

Thanks.

RE: Converting sketch to lines and arcs.

Is there a solid body associated to the sketch ?

RE: Converting sketch to lines and arcs.

(OP)
No solid body. Just "tracing over" a bunch of splines with sketcher to get nice tangent lines and arcs.

RE: Converting sketch to lines and arcs.

I think the way that you are doing it now is probably the best way.
But I would be interested in hearing others.

RE: Converting sketch to lines and arcs.

(OP)
Yeah. It seems like you should be able to kill the parameters of a sketch and it would then be just the lines and arcs.

RE: Converting sketch to lines and arcs.

An alternative method (though not necessarily easier/faster) would be to:
  1. Use the extract geometry command, composite curve type, turn off the associative option, and for 'join curves' choose 'no'.
  2. Change the curve selection rule to "feature curves", select the sketch and press OK. You can delete the sketch now, assuming it has no child features.
  3. Use Edit -> Feature -> remove parameters and window select around the newly created curves that make up the composite curve feature. Press OK and you will be left with unparameterized curves.
I'm using NX 8.5, other versions will be similar.

Future enhancement: allow delete parameters to be used on sketch? Right click on the sketch and wap the parameters just like on anything else...

Thanks for your input guys. I thought for sure I was missing a really easy way but apparently not.

RE: Converting sketch to lines and arcs.

I just 'Copy' the sketch curves to another Layer, then delete the Sketch, and if it's critical, I simply 'Move' the now 'dumb' curves back to the original Layer.

RE: Converting sketch to lines and arcs.

or can't they be copied to the same layer that they are currently in, and then delete the sketch ?

RE: Converting sketch to lines and arcs.

Yes, technically the destination Layer can be the same as the current Layer, which makes this approach easier yet.

You'll get lines and arcs.

RE: Converting sketch to lines and arcs.

I have since a couple of versions back wondered how the intended way of creating drawing borders was.
( I see no point in having the border parametric, at last not in NX7.5.)
And since the development direction is to phase out the old basic curves we will , eventually, be forced to use Sketch.
I have used Export CGM + import CGM for the purpose.

Tomas

Project curves, unassociative, done.
