FreeCAD NX-Style

OPEN-SOURCE CAD · FAMILIAR WORKFLOWS

Your NX habits.
A FreeCAD foundation.

Sketch, build and document parts with an NX-style ribbon, command names, mouse controls and shortcuts — powered by your unmodified FreeCAD.

Recent additions bring feature creation, sketch control and STEP exchange closer to the way you work. See what changed →

  • Pick the curves. Build the feature.
    Extrude and Revolve now accept a whole sketch or selected curves from one sketch, with tangent and connected selection rules. Their command boxes bring Boolean choice and validation into the workflow.

  • Start with a solid.
    Block, Cylinder, Cone and Sphere have NX-style dialogs, point picking, live previews and Boolean operations. Continue with datums, holes and detailed features.

  • Exchange more than a shape.
    Export and rebuild supported feature history, sketch constraints and parameters. Check incoming STEP files, identify the application protocol and inspect the product structure.

Follow your engineering workflow

From the first sketch to a drawing, an assembly check or a released part. Find the tools for the next step.

Learn by making something real

Work through a part, inspect the result and see what differs from NX. Each tutorial pairs the steps with recorded replay outcomes.

Familiar on the surface. FreeCAD at the core.

NX-Style adds the ribbon, navigators, selection tools and command workflows to FreeCAD. Some commands have NX-style dialogs; others use FreeCAD’s task panels. Your models remain .FCStd files, and your normal FreeCAD profile stays separate.

It is not Siemens NX or a claim of full NX capability. The guides explain supported options and the differences you will encounter, including limits on selected sections and STEP feature history.
