File formats: supported tools and honest limits

Check the actual source format before choosing a converter. STL export and mesh exchange are different from opening an editable project, reconstructing CAD or generating printer instructions.

CTM to STL and 3DS to AMF: prepare a supported mesh

There is no direct CTM to STL uploader here. Open the CTM source in a compatible application and export a supported polygon mesh such as OBJ or STL. The same preparation principle applies to 3DS to AMF: the source must be read by suitable software before it can enter a supported mesh workflow.

Any .ctm to STL workflow must decode the source geometry; changing the extension does not convert the stored data. Check a known dimension, object placement and the resulting surfaces after any external export.

Convert a prepared OBJ mesh to STL · Export supported STL geometry as AMF

ZTL, LYS and CATPART need source-aware export

A ZTL file, a .lys file and a native CATPART document are not interchangeable triangle-mesh containers. Their source data may require the original or a compatible application. Keep the source project and use its available mesh export rather than changing the extension.

This site does not directly convert CATPART to STL or LYS to STL. If the source application provides an appropriate export, save the intended visible geometry as a supported mesh or CAD exchange file and inspect the result here. Do not assume every project contains a self-contained exportable model.

Check supported CAD exchange workflows · Browse the actual mesh inputs

STL to SDF: clarify what the destination means

SDF is used for different kinds of data, including signed distance fields in geometry workflows. No SDF exporter is available here. Identify the exact destination specification and compatible software before attempting an STL to SDF workflow; a triangle mesh cannot be converted reliably by extension alone.

STL to PNG converter or three-dimensional viewer?

This site provides a model viewer, not a dedicated STL to PNG converter. If you need a raster picture rather than a mesh, use a compatible viewer or rendering application to frame the model and export an image. Keep the STL when you still need three-dimensional geometry.
