I just installed MEP and never used it before. I am currently working a project that needs to be in 3D (no more 2D plumbing drawings) I have tried the tutorials and they really didn't show me too much. I ran my supply lines and they all look good, but now I am trying to run all my drain lines and really can't figure out why they are not coming out right. I guess my question is, where do I begin, I tried starting off in plumbing, but can't get the pipes to look 3D, so I went to PIPING, am I starting off in the right direction?

Thanks,
