NX Extrusion Bend
NX Extrusion Bend
(OP)
Hello all. I have a straight extrusion in NX 7.5 solid modeling that I need to bend to a certain radius/angle. I saw a previous post about this but it didn't completely solve my problem. I would like to model a tool, a chisel for example, straight and then bend it to an angle afterwards instead of sweeping or revolving the bent portion. This is how it will be done in production. Any advice would be greatly appreciated. Thank you.

Open the file and edit the Solid 'bar' by double-clicking. When the Swept dialog opens, in the 'Guides (3 Maximum)' section of the dialog, select the 'Select Curve (1)' item and then de-select (shift-select) the Green curve. Now select the Blue curve and hit OK.
The result will still be a single seamless solid 'bar' since the original sketch, made of a line and an arc, was 'converted' (associatively) to a single segment spline by creating a 'Join' curve feature (the Blue curve). Also note that the length of the original sketch is controlling the length of the solid 'bar' so is you edit the sketch named 'Final Shape', changing the length of the straight section and/or the radius and angle of the curved section, when you update that sketch, the length of the 'guide' curve used to create the solid 'bar' will change as well. Note that there was NO attempt to compenstate the length of the bar, as it went from the unformed to the formed state, for the effect that deforming a shape like this would have on the actual profile and length of the deformed portion of the solid 'bar'. In other words, the result is an idealized shape.

With an arbitrary shape it's very difficult to apply a 'bend' which would result in a reasonably accurate final shape.

Thank you very much for all the help and time you've provided. I suppose it makes sense why NX functions this way.
Another quick question I had is how can I snap to existing geometry in the sketch module. I am able to use project curve to be able to snap a few lines on the end of existing features, but these lines are able to mvoe anyway. Am I missing something big here. It seemed innate to other systems to snap to existing geometry easily.
Thanks you,
Mike
