⚡ Interactive 3D

Upload a 3D CAD file to see a rotatable 3D model.

3D preview formats: STEP/STP, IGES/IGS, STL, OBJ, BREP, GLB, embedded glTF, PLY, OFF & DXF with 3D faces.

3D CAD previews automatically; flat drawings stay 2D. Up to 10 files · 50 MB each.

Supported 3D & 2D formats

3D preview: STEP/STP, IGES/IGS, STL, OBJ, BREP, GLB, embedded glTF, PLY and OFF; DXF files with 3D faces. Local preview up to 10 MB / 20,000 triangles.

2D drawings: DWG, PDF, JPG and PNG can be submitted for review. A flat drawing is not automatically converted into an accurate 3D model. For DWG/2D DXF, send a matching STEP/STL model for direct 3D preview.

By clicking Send, you agree to send these original drawings, requirements and contact details to BOLTTE (boltte@boltte.com) for a quotation. Small files are emailed as attachments; large files use private, expiring links.
