Surface Help

Does anyone have any tricks for turning this quad surface into a single smooth surface? We need to create some tooling and these surfaces don't want to cooperate.

You would have to use a loft with guide curves. I was going to have ago referencing off your geomentry, but I could not copy the doc.

Unfortunately there is no one button/one surface solution to this problem. 

Like Bruce suggested, I sliced  your geometry and began re-creating surface patches based on curves produced from these slices.



It's a little bit of work, won't be the exact geometry, but it would be close. I tend to want to create datums and incorporate these slice curves into a structure allowing modifications when complete. After all this is a parametric system and this geometry should rebuild some how.

In the end, you'd have better geometry as this scanned data has many nooks and crannies in it's current definition. You can improve the surface quality.

It'd take me a day to create this model. But in the end, if this was the end of a golfer's driver, I'd have the entire set of drivers using parametrics.

I did try splitting it into slivers and creating section sketches, but couldn't get the loft command to play nice.

Thank you for the feedback.

I have made a copy of your document and i have made the part out of less surfaces.

Impressive!  About how long did it take to do this?  And does it matter what order you pick edges & guides?  How did you determine how large to make each 'patch'?

I need to add surfaces often and your example is a big help.  Thanks!
