offset a curve in a sketch

[bartbrejcha]

I located the offset a curve function in sketcher mode but unsure how or if I can offset a curve that is a previous sketch. Im modeling a rod from a piston and rod assembly. I want to core out the rod shaft using surfaces by extruding or sweeping to a curve. I have one curve feature on each side with two separate sketches. Now in a new sketch I want to generate a path for a sweep.

BTW I appreciate all the activity on this forum.

how can I edit my post? I was trying to add a picture to it instead of adding a new post.

You can't edit a post to an Eng-Tips forum once it has been submitted (I would like that feature as well but so far we haven't been able to convince the powers-that-be to implement something like that, but maybe someday...).

As for your original question, try projecting the curves from the other Sketches into your new Sketch and then create your Offset Curves.

hey john. you a huge help. I administered a Pro/ENGINEER class in Cyprus CA to Yamaha in 2007 or so. It's cold in Chicago this week for some reason as if it's not summer. I am a little handicap-ed w/o an insert function. In a previous post you mentioned a way to insert a sketch up in the tree. Is there some reason you don't allow that functionality? If SW uses the UG kernal that tool allows that functionality.

I think the way NX does it, while it may take an extra step, is much more usable and easier to understand the effects of what you're doing since it allows you see and work with the model exactly as it looked like at that point in the Timestamp where you want to 'insert' your new feature(s) so that there's no question as to how it was applied before you return back to the final model. Also once you've set the 'Current Feature' you're now able to add as many features as you want by simply doing what you'd do if you were adding features to a regular model. Once you've added all the features that you want, it's just one additional step to return to the final model with your new features 'inserted' at the proper Timestamp.

yea. my brain is wrapped up in Creo - Pro/E world for so long. In my effort to be careful to not make a reference to an improper feature I would go into insert. I did play with re-ordering quite a bit. I feel comfortable. Top Down design is next WAVE
