Re: In the piping extension can I change the colour of piping and if so how?
Are you using "spec-driven piping"? If so, there is a way to set the default color of what pipe gets created via the spec library files.
If you are not using spec-driven piping, you should still be able to change the color of the pipe via the "Appearance Gallery" under either the "model" or "render" tabs. Since the pipes are created as "features" of the assembly, you have to change the color of the entire pipe assembly though.
