Converting sketch to lines and arcs. 1

[hexfly]

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.

Is there a solid body associated to the sketch ?

 

[hexfly]

No solid body. Just "tracing over" a bunch of splines with sketcher to get nice tangent 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.

 

[hexfly]

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.

An alternative method (though not necessarily easier/faster) would be to:
[ol 1]
[li]Use the extract geometry command, composite curve type, turn off the associative option, and for 'join curves' choose 'no'.[/li]
[li]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.[/li]
[li]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.[/li]
[/ol]

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.

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.

[jerry1423]

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

 

[JohnRBaker]

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

Insert > Derived Curve >Simplify Curve > Select Maintain, Delete, Hide (at your preference) >Select the curves of the sketch.
You'll get 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.
