riser structure

[gandocadguy]

Here's my problem....

I need a riser structure. I attempt to edit a rectangular structure but I am unable to get it to attach to the invert of the pipe. Is there a way to attach the pipe diameter or vertical dimension to a structure as a variable?

Or anyone have a riser structure to share?

Can you clarify a bit what the rectangular structure is representing? When I hear riser, I think a cleanout or drain but these are usually cylinders. Just for my info, is it a catch basin you are attempting to make? I might be able to help...

Usually when you use a structure of any kind it is designed to attach to a pipe's invert. Hit me back...

Thanks for the reply. Attached is a picture of the riser (SW4) represented in profile. It is a rectangle in this case though there are/can be cylindrical ones. My main problem seems to be being able to get it to properly attach to the invert.
