I'm not too hot on this whole sub-divide business, so a quick question........can sub-divide help to model real objects (say, an aircraft) accurately, from base polylines/splines? or is it just make made-up stuff look good??!!

One application of subdivide can round off a low poly model made to accurate dimensions.
For non-fiction aircraft, its a trade off between poly budget and appearence like all modelling. So its more usefull if your end target is a picture of the aircraft, than if its a model for in game use.
IMO Its one more string in your bow and all AC3D users should familiarise themselves with it, but that applies to all AC3D commands. Each one gives you more possabilities.

Been working on a Trek style control panel. Can't figure out a way to make the cut-outs in the top for the recessed panels with all the okudagrams and etc.

I figured one way to give objects a nice rounded edge with subdivision without totally changing the shape of the entire object. It involves extruding two or more surfaces so that when you subdivide the object it rounds the edges instead of changing the over-all shape of the object so much. Here's an example pic:



Then I set Crease Angle to 180, subdivide twice then Smooth and I get this:



There seems to be a little bit of a bug in the Extrude function though, sometimes the vertices drift off axis while the surface is being moved and they have to be corrected manually.
