Which file formats for plans, documents and images are supported?


Information: No multi-page PDF files are shown because we are strongly against combining plans into multi-page PDFs. In our experience, this leads to more difficult version control, among other things.



Maximum file size: 1 GB

2D (scanned plans):

With scanned plans, we have found that there can be processing issues if the files are not compressed. However, PDF files can be optimized with third-party tools.

For example:, uncompressed: 67 MB, approx. 30min processing time (too long, breaks), compressed: 3.5 MB, approx. 3min processing time.

3D (CAD/BIM/Model files):

.3dm, .3ds, .a, .asm, .brd, .catpart, .catproduct, .cgr, .collaboration, .dae, .dgn, .dlv3, .dwf, .dwfx, .dwg, .dwt, . dxf, .emode, .exp, .f2d, .f3d, .fbx, .g, .gbxml, .glb, .gltf, .iam, .idw, .ifc, .ige, .iges, .igs, .ipt, .iwm, .jt, . max, .model, .mpf, .msr, .neu, .nwc, .nwd, .obj, .par, .pdf, .pmlprj, .pmlprjz, .prt, .psmodel, .rvt, .sab, .sat, .sch, . session, .skp, .sldasm, .sldprt, .ste, .step, .stl, .stla, .stlb, .stp, .stpz, .vue, .wire, .x_b, .x_t, .xas, .xpr, .zip

These files are sent to the service "Forge" for rendering (formatting). The server is located outside of Switzerland, in Europe.

Note: If not all elements are displayed when uploading an IFC - file to smino, we recommend to use the BREP setting.


Basically all formats can be uploaded here. PDF files can be displayed directly.
