Archicad 29 MEP – How can I add 2", 4", 6" and Fire Riser pipe sizes?

Hello everyone,

I hope someone can point me in the right direction because I am currently stuck on a real project.

I am using Archicad 29 (standard license) with the native MEP Modeler.

While modeling the plumbing and fire protection systems, I noticed that the available Pipe Reference Set only includes diameters up to DN65 (75 × 4.7 mm).

For my project I need, at a minimum:

2" pipe (domestic water and some fire protection branches)
Fire sprinkler riser sizes (4" and 6", depending on the hydraulic calculations)
4" PVC sewer
6" PVC sewer

These pipe sizes are essential because I am coordinating all disciplines in BIM and need to perform clash detection. At the moment I cannot accurately verify whether the sanitary stacks and fire risers fit within the limited shaft space available.

After researching the documentation, I learned that Route Specifications appear to be available only in Archicad Collaborate, and this option does not exist in my installation.

My questions are:

Is there any way to add additional pipe diameters in the standard version of Archicad 29?
Do I need an additional license or module to edit Pipe Reference Sets?
Can Route Specification XML files created in Archicad Collaborate be imported into the standard version?
Is there an official Graphisoft library (for example Sewage Inside, Sewage Outside, or Fire Protection) that includes these larger pipe diameters?
Has anyone successfully added 2", 4", and 6" pipe sizes to the native MEP Modeler?

I would appreciate any guidance, examples, or recommended workflows.

Thank you very much!

Hello.
You need to configure and create your dimensions; this will standardize pipes, materials, transitions, elbows, and so on. There's no difference between Collaborate and the one you have (if it allows you to model MEP).
