Michael – I don't know of any 3D software that does not initially subdivide curved surfaces into facets. However, packages such as DesignCAD 3D v4.xx let you decide how many facets you want. Depending on the size of the object, using, say, 360 facets around the perimeter gives a pretty smooth surface – but one cluttered with lines. If you want smooth curves, you have to model. What you can do, with a wireframe, is store it as a 2D image after you create it. Then you can go into the 2D image with a 2D package and edit-out any lines you think are extraneous. 2D-3D combos can be had for about $500 or less on the street. — gtm —
