good afternoon, I have a simple 1 bedroom floor plan and I am designing a 3D plumbing layout as seen in the photos.    Since this is a 3D software, I am surprised that the developers have not created more MEP tools to create such 3D layouts like this.   I had to import a 3D symbol of a pipe to do it this way. And as you can see, there is no elbows or anything like that..i had to use all 90 degrees connections.   does anyone know how I can get these waste lines (yellow) on a 1/4" slope?
