Re: 3D CAD Piping Questions'' Answers - Followup

I like 3D also, what I'm saying is that it is now very expensive for a smaller business to get into the market and what type of software one knows/has can determine whether a contract is won.

And as Bruce mentioned, it looks like 2D drawings will be needed for plant construction by builders for the forseeable future, mainly to keep track of changes/revisions.
