create associative curves in 3D for wire routing

create associative curves in 3D for wire routing

(OP)
Hi, I have been given a work in which I need to create a wire with several bends using curves(without using sketch and the curves are not in one plane), and the bend radius should be parametric(fillet in Basics curves wont update with the change in adjacent curve length), Is there any method for creating this type of curves(we do not have licence for mechanical routing). Thanks in Advance.

RE: create associative curves in 3D for wire routing

Please include your NX version when posting for help.

Assuming you're using a version with NX that has this, Associative Arcs work for us but we typically do not completely re-route the path to the point that the arc's plane cannot be defined (in other words, our bends are planar). We also have the straight section endpoints meeting to form the intersection at the bends and use Follow Fillet with our Curve Rule.

RE: create associative curves in 3D for wire routing

You can create lines and arcs in 3D space that are associative to each other. To model wires, I often use the line command to model the constrained part of the wire, then use bridge curves to connect the lines. Bridge curves can smoothly connect non-planar curves and result in a fairly good approximation of what an unconstrained wire will look like in the real world. It offers some control over the shape, but you will not be able to directly control the radius. If parametric radius control is really needed between 2 non-planar curves, the "circular blend curve" may help. If I remember correctly, this creates a spline that essentially lies on a cylindrical surface; when projected along a certain direction, the spline will appear to be an arc.
