irregular surfaces

Use the "Irregular Surface" feature under the Insert --> Surface menu.

Tick, Actually it's much easyer in SW 2006. RMB on the "regular" surface and select >Make Irregular.

LOL, Muggs

I think several resources for learning have been suggested already. Find Ed Eaton's DiMonte Group curvy stuff tutorials . Check out Mike Wilson's sample parts and reverse engineer them to see if you can reproduce. Here are some additional tutorials:

The easiest way to do it at this point might be to post what you have so far at and ask someone else to do it for you.

Surface fill is a good one to know. From your earlier post I assume you are trying to create a little dip in the seat for the guys butt? You can use s plit line to specify a region to get dipped, delete the face (choose delete, not delete and pathc or delete and fill), create a sketch for where you want the dip to go, then use a surface fill, tangent boundary, and select the sketch as a control curve. If that doesn't get what you want, you can then revert to a surface loft. Then knit everything back up into an enclosed volume and convert back to a solid.

Some folks use dome and deform too, but I prefer to have more control over what I make.

If, on the off-chance you are trying to model a texture - umm, don't.

Did you do a search for a car seat? I know for sure about 3 years back someone modeled a car seat as a tutorial. I just don't know where I saw it. Anyone else remember what I am talking about?
