Regum 3D

About the application

Polygon modeling for print parts, game props and product mock-ups.

Build with extrude, inset, bevel, loop cut, knife, mirror editing and booleans. Work in millimeters, centimeters, meters or inches, type exact lengths, snap to geometry and measure distances and angles. Mesh checks show open and non-manifold edges, flipped faces, volume and surface area; these are basic checks, not a guarantee that every model will print successfully.

Save editable .regum3d projects with preview pictures and automatic crash recovery. Import OBJ, STL and glTF; export STL and 3MF for printing, OBJ and GLB for other 3D tools, or PNG images. Materials support color, metalness, roughness and transparency.

Optional RegumAI integration can read the scene and propose modeling edits or geometry exports. Enable access in Preferences, grant access to the current document and an export folder, and approve each write in Regum 3D. Access starts disabled each launch.

Requires Windows x64 and Microsoft Edge WebView2 Runtime. Setup installs for the current Windows user and may download WebView2 from Microsoft if it is missing. The application interface is in English. Animation, rigging, sculpting, texture painting, UV unwrapping and CAD constraints are outside this application's scope.

Made for your workflow

What you can do.

• 01 Start from boxes, spheres, cylinders, cones, toruses, planes and lathe shapes with an editable profile.
• 02 Select objects, vertices, edges or faces using click, box, lasso or brush selection, with X-ray selection through the model.
• 03 Preview extrude, inset, bevel and sliding loop cuts; draw knife cuts and enter exact lengths for extrude, inset and bevel.
• 04 Combine solids with union, subtraction and intersection; use mirror editing, arrays, duplication, join and separate.
• 05 Snap to steps, vertices, edges or surfaces; measure distances and angles, and inspect the model in a four-view layout.
• 06 Inspect topology, volume and surface area, and assign material colors, metalness, roughness and transparency.
• 07 Save recoverable .regum3d projects; import OBJ, STL and glTF, and export STL, 3MF, OBJ, GLB and PNG.
• 08 Search commands with Ctrl+K, open keyboard shortcuts with ?, and use undo for modeling edits.
