First of all: Thanks Bobo
Second: tested in MAX 8

The columns have different elements to apply different materials.

The Radiosity parameter increase the number of poligons in the column only, because softwares which calcutate radiosity like square poligons.

The rectangular planes at the start and the end are for creating the floor and ceiling meshes (from boolean operations on other objects) so, they have to be detached manualy at the end. Another time, this is only important for radiosity solutions.

Nice work, now all you need is a Doric/Ionic/Corinthian radio button...:)

Thank you focomoso, but too much for me. In my language: "mucha arena para mi camioncito" ;-)

I'm involved in some arquitectural projects now but all modern style, so not needed ...

But next step will be the creation of ceiling and floor meshes.
These would have the hole of each column, the outside delimited by a polyline, and with square faces only. Uhmm... not too easy.
