can multiple lines be changed to a polylines?

Box one was created using lines. It was then given a height using the EXTRUDE command. The result is a four sided box (open inside) comprised entirely of surfaces.

Box two was created using a continuous polyline. It was given a height using the EXTRUDE command. The result is a solid through and through. Slicing the box in half would confirm the fact.

Box three was constructed from four lines but instead of using the EXTRUDE command the PRESSPULL command was used. The result is a solid. This can be confirmed either via the Properties palette or as I have shown here (box four) slicing the box in half.

I would argue that the CONVTOSOLID command is not obsolete at all. Just because the command failed doesn't mean it is obsolete. The failure, as it were, could be attributed to the geometry that is being used or the fact that the user did not understand or follow the command prompts.

Has SURFSCULPT stolen some of CONVTOSOLID's thunder?
An honest question, having not used either one.

[Dadgad]

in learning the CONVTOSOLID command you probably learned other things that will still be useful down the line.

yeah, like PRESSPULL!

Note that meshes can be converted to solids using CONVTOSOLID.

I would agree that SURFSCULPT would probably be of more use to the OP as long as he was working with the proper geometry.

I'm guessing you took my advice about hooking up the IV ITALIAN ROAST drip yesterday, that or you slept a lot better last night, firing on all cylinders today!

Seven out of eight cylinders are cranking along. I'll be working on the eighth in just a couple of minutes. Coffee break time!
