Get a ready-to-use Plant 3D piping class

We process your spec into a native piping class: 3D models with the correct properties assigned, the spec and catalog, and the branch table. Everything you would otherwise set up by hand, checked in Plant 3D before we send it.

01Line items

Every line item correctly defined against the right standard

We retrieve the dimensions, materials, ratings and every other property of each component, then compare them against the relevant standard, such as ASME, EN or ISO, and your company guidelines.

02Branch tables

The right fitting at every branch

We set up your branch table in Plant 3D, so every header and branch size gets the right fitting, in your order of preference. Anything your sheet doesn’t cover, we ask about instead of guessing.

03Parametric components

3D models for every size in the standard

We build the 3D model of every component. Each one is parametric, so every size, pressure class and wall thickness in the standard is covered, with dimensions that follow the published tables.
