Break or split geometry in sketch
Break or split geometry in sketch
(OP)
First off forgive my basic questions I am new to NX, but so far the responses have really helped get me further, so thanks.
My first question:When working on a sketch in direct sketch or task mode on a plane, not individual free curves in 3d space,is there a break or split command,I found trim and extend but what if I want to keep the geometry?
Say I want to just divide a circle with lines that radiate out from the center at different angles?
My second question:First off In Shape Studio say I create a simple four point surface looking from the top view and I edit the surface with X-form to make it a say degree 3 single span.Then lets say half of the control poles I move with X-form to be on the right side of the top plane and the others on the left(in otherwords straddling the WCS YZ plane.
Is there a feature that will apply symmetry to the surface so that I only have to manipulate half of the poles on one side and the other side would automatically mirror the pole positions? from what I can see the symmetry command only snaps the edge of a surface to a mirror plane of your choice.
Thanks a bunch. Win 7 64 bit NX 8

RE: Break or split geometry in sketch
As far as X-form goes, I'd imagine you'd have to trim the surface to the plane, X-form (making sure the edge on the plane remains on the plane) then apply symmetry command then finally Mirror surface about said plane. If you were moving them all in the same direction (positive or negative in Z only), you could grab all poles and move them, but once you start moving in the X direction, you'd have to move in opposite directions, so just one side at a time when straddling the YZ plane.
You could also keep track of the step values and move in one direction at a time, performing the operation once on each side of the YZ plane, moving in the exact opposite X direction each time. Would tend to be a little tedious. There might be something you could use in Synchronous Modeling on a solid
Hope this makes sense and/or helps.

RE: Break or split geometry in sketch
how about a divide command so that you can do things like divide a spline into equal lengths and specify how many lengths.Rhino certainly has a split
and divide command and many cad programs I can think of.Hum life without split and divide.
Thanks Buddy.
