In this tutorial, we cover Cut/Remove, Extrude/Add, and Relations in HVH Designer, walking through the full process of building a 3D pipe model and assembling a complete pipe fitting assembly from scratch.

The first part focuses on part modeling. Starting from a 2D sketch, Extrude/Add is used to generate a solid 3D pipe body, and Cut/Remove is applied to subtract material and shape the part with precision. Relations are used throughout to keep sketch geometry fully defined, properly constrained, and free from modeling errors.

The second part moves into the assembly environment. Individual pipe fitting parts are inserted into a new assembly, and mates are applied step by step to position and constrain each component accurately. By the end of the assembly section, all parts are fully constrained and the pipe fitting assembly is complete and production ready.

These are the core tools of parametric solid modeling in CAD, and this tutorial covers them in a practical, hands-on context that applies directly to real engineering workflows.

HVH Designer is a cloud-based CAD platform that runs entirely in the browser with no downloads, no installations, and no expensive hardware required, accessible from any device, anywhere in the world.
