No matter what value I give it the pipe is just a single tube with no wall thickness.<BR /> <BR /> We are trying to model some civil stormwater lines that run under our buildings using the MEP tools. The pipe walls in some instances are up to 300mm thick (2500mm dia pipe and bigger).</T></DIV> Wed, 24 May 2023 11:04:35 GMT https://community.graphisoft.com/t5/Modeling/MEP-wall-thickness/m-p/179815#M97705 Matthew Johnson 2023-05-24T11:04:35Z https://community.graphisoft.com/t5/Modeling/MEP-wall-thickness/m-p/179816#M97706 Matthew:<BR /> <BR /> Looking at the <FONT color="blue">Pipe Straight 15</FONT> object, in the Master Script there is a call for the <FONT color="blue">MEP_m_Pipe_4</FONT> macro, but the <FONT color="blue">ConWallThickness_1</FONT> variable (for the Wall Thickness parameter) does not show up there, so I am guessing that this parameter is for listing only, with no effect on the 3D model.
