How to scale curves? 1

[NXMold]

The old transform dialog has been on the move, and seems to be completely gone now (NX 7.0.1.7).

How do I scale curves?

Have you tried the command finder?

Transform - Scale should (non associatively) scale a curve.

That's one of my pet peeves with NX, that you can't associatively scale curves.

you can however cheat! extruding any kind of sheet or solid body from the curves creates a body which CAN be scaled.

QED! But inelegant.

If it's a B-curve you can use X-form to scale it. And of course Arcs and Ellipses can be 'scaled' by simply editing their 'parameters'.

Well, when I say associatively what I mean is being able to edit the sketch and modify various dimensions after it's been scaled. That's probably really something else.

I design plastic bottles. When I used "CAD system X", I could build say an 8 oz. bottle. If I wanted a 16 oz. bottle that had to look like a family to the 8 oz. I would figure out a scale factor, taking into account things that will change between the two bottles, like say weight and finish size. I could then copy the 8 oz. part and apply the scale factor. The system would multiply every dimension by the scale factor. The resulting part would be very close in volume and I just had to do a little tweaking to get it right. Every feature could be modified as if I had built the geometry myself from scratch.

I can't do that now. I have to go through each feature individually and modify every dimension. That's what I mean by not being associative.

The curves in question are lines, arcs, and splines imported from other cad systems. In my recent problem, they took the shape of text that had been projected onto a 3d contoured surface.

None of the cheats posted would work here. Searched command finder for "x-form"... looks like a surface only tool. Searched transform and found what I was looking for, turns out I put the #@(*!# thing on my toolbar last time I spent a half hour looking for it but havnet used it since and forgot what the hieroglyphic meant. Looks like it isnt in the menus anywhere.... thats helpful.

Transform should be under Edit, but you'll likely have to add it to the menu yourself. We looked all over for it after our last update and then realized we had to add it through Customize. Must be they're trying to phase it out.

Yes, they are. But they have yet to introduce another way to work with curve goemetry.
