How to trim/extend projected curves in sketcher?
(OP)
I am creating a part which needs to reference off of imported data in order to match existing surfaces. When I go into sketch mode, I use the project button to "copy" the edges from the imported surface. The section is basically a "U" shape - 2 vertical lines, a horizontal arc, and corner rounds. I do not want the rounds however. How do I trim/extend the section so I get sharp corners?

Everything should be designed as simple as possible, but not simpler.

This option trims two curves to their intersection point, thereby forming a corner. The corner that is created depends on the objects selected. As with all Edit options, the portion of the curves selected, with respect to their intersection point, is trimmed/extended. When you select curves for a corner trim, position the selection ball so that it includes both curves.
If the selection ball contains only one curve, an error message is displayed:
No Valid Curves

feadude: I tried your suggestion too, but it's giving a "cannot corner trim this curve in sketcher" error. I can trim all I want if the sketch features cross each other, but if the sketch features have a gap between them, the corner trim doesn't work. The trim corner option doesn't seem to work for projected curves and splines, but it works with arcs and lines. I am getting around it by "tracing" the imported edge with arcs. Not happy about it, but it's close.
We do this all the time with Pro/E and Solidworks parts. I can't believe UG is not capable of doing such a simple operation.

If the answer is "no", you can skip the sketcher entirely.
Even if the answer is "yes" you can probably skip the sketcher entirely.

when you project curves in sketch turn the "Associative" ( it looks like two chain links) off and then project curves then delete the rounds and trim/extend corners. It works . I just tried it.

The feature does need to be parametric.
Skipping the sketcher entirely? As a seasoned Pro/E user, we use sketches to form most of our curves. It's tough to grasp the concept of these "floating" curves. Guess I need more practice to get used to it. I've only been using UG for about a week now.

Then you can delete the temporary line after it's served its purpose.
