Hi, I'm trying to make a wing and I need a way to copy the cross section to the other end of the two lines in the pic below (to make the shell via surfaces).

Is there a good way to do this? Every time I copy the section it just disappears when I try and paste it in a new sketch (because of constraints, I'm thinking).

I really just want the wing--I don't care if it's a shell or solid...it can be a blend or variable section sweep or whatever, I just want it to work.

Also, I tried those more advanced techniques and it doesn't let you use a previous sketch for the sweeps/blends, you have to define it all over again, which I don't want to do. Is there a way to do this?

Thanks a lot.

Better yet, I've managed to copy the section and make it smaller, but I want to constrain the entire part (with out warping it) to the axis through it's length (the long axis), is there a way to move and entire part through constraints?

Here's the latest pic:

I was able to create the second sketch by select the vetices at the end of the lines as references, making an edge copy of the first curve and placing a sketch point on the round end of the sketch, copy the curve and the point and paste. You should see a red sketch with modification handles. Place your cursor over the white circle with the X inside, right mouse click and move the handle to the tail end of the sketch, then move the sketch so the tail end lines up with the appropriate reference point. Using the same procedure as before move the scale arrow to the point on the nose end of the sketch and drag the scale arrow to the appropriate reference point. Here are pictures of what I ended up with.

What's the best technique for creating a curve such as an aifoil cross section in Proe? I have tried this more than once and the curve usually contains many points. Proe wants to dimension every point in the sketcher.

How did the two of you do it?

• Export file as IGES, and select ‘Datum Curves and points’

• Rename file from *.IGES to *.pts
