Simplify / Edit Laser Scanned surface...

Simplify / Edit Laser Scanned surface...

(OP)
Hello there,

I'm in a bit of a bind needing to have a good model from this laser scanned surface in about 10 days. I also have only worked with surfaces a few times, and they were easy, "from scratch" surfaces, not this complicated thing.

In any case, I had this part laser scanned and was given a .stp file which contained a surface model of the part. I need to smooth out the top (flat) surface, delete a few features and patch them. I also need to move a few things around, and add in some features that are missing from the laser scanned surface- holes, etc.

So far, I've tried to simplify the surface and get it flat that way, by deleteing the data, creating a guide curve sketch "mesh" across the gap, and trying to create a new surface across the gap which would hopefully be smooth. I seem to get all sorts of wavyness, as if the boundary condition takes precedence over the guide curves...

My question is: would I be best to make a few sketches that show the "tricky" geometry here, and simply model this thing from scratch... Most of the smaller features etc are being delete anyways. Or, if I SHOULD stick with this laser scan as the basis of my model, how should I proceed. If this is the case, does anybody have any suggested reading? The books I have here all deal with "from scratch" creation and I'm having a hard time applying that to this.

Files are here (SW2010 or .stp)

Please take a look and let me know!  

RE: Simplify / Edit Laser Scanned surface...

If it's easier, use the scanned part as a base feature (Insert > Part) in a new part, and use the base feature to create geometry (Intersection Curves, etc) for the "from scratch" part.
