WHAT IT DOES

ZForm, in practice.

ZForm models exact boundary-representation solids. Build from primitives or Profiles sketches, modify faces and edges, and exchange solid geometry with CAD tools.

01

Sketch to solid

Use the companion Profiles extension for constrained sketches, then extrude, revolve, loft or sweep in ZForm.

02

Direct solid editing

Fillet and chamfer edges, push or pull faces, shell bodies, and combine solids with Boolean operations.

03

Editable feature structure

Parametric feature editing, sketch relationships and named parameters support design revisions.

04

CAD exchange

Import and export STEP, BREP and IGES; export STL and DXF for downstream workflows.

BEFORE YOU START

The right setup.

Package: ZForm, Assy, Profiles, Para and Shell. Use the ZForm package for your operating system and processor.

Select the correct platform build: Windows x64, macOS Intel, macOS Apple Silicon or Linux x64, as supplied. Keep bundled binary dependencies with the package. Enable Profiles for sketch workflows and Para for parameter workflows.
