Well, I hope it is anyway!

All I'm trying to do is create a surface that stretches over the top of the curves that I've generated as per the attached image.

It should be really simple but I've got a bit of a mental block and can't get anywhere with it - any help would be much appreciated!

Thanks, Andrew.

this can be done however it is not a simple solution to your apparent simple problem. First notice that the geometry does not leave any four part boundary.

Thats the only hint I give you for now. Its kind of like a crossword puzzle. You need practice to get your mind thinking of these solutions. After a while you start to solve these problems in your head like a puzzle. Then the puzzle is not so much fun to solve and you look for more challenging puzzles.

Attached is my concept of this part, and it is in WF 3.0 as was the original. From the shaded curvature analysis, you can see the areas that need improvement.

I would also be interested in knowing what surface features other Pro-E users recommended for modeling this part. Lately, I have been using SolidWorks and could use a refresher on Pro-E suface modeling techniques.

I tried this again using the ISDX module (FreeForm Surfacing) inside Pro-E to create a loft surface (instead of boundary blend). It showns improvement, but many Pro-E users do not have the ISDX module unless it was purchased as an extra module.

I would be interested in seeing the Bart's solution. I may try testing this in SolidWorks later to see how it compares to the Pro-E module.

Simple? No.

Studying variations of that will introduce you to many of
the basic concepts and some of the finer points you'll need
to come to grips with for 'complex shape' modeling.

Thats what I was thinking. I call that the toupee method because it has a bald spot or a trimmed back four part boundary .... to make in the end a four part boundary.

Its a little extra work but the result is so much nicer. I would not even think of doing it another way.
