The following example shows how a single triangle polygon is defined within an ASCII STL file.ġ) Always source your CAD files as "BREP solids" geometry items.Ģ) Set the appropriate 'mesh tessellation' tolerances on the CAD importer.Ģb) Import the CAD model with the Okino 'CAD Optimizer' enabled by default.ģ) Upon import check that there are no 'naked' edges in the model. This export converter writes out 3D scenes to an ASCII or binary formatted 'StereoLithography STL' file which can be read by manyĬAD/CAM and 3D printer related software packages. VRML2 is often a much better file formatįor moving 3D datasets into downstream programs and/or 3D printers. Texture coordinates, no assembly hierarchy part naming or any material assignments. Rather, STL defines just a raw triangulated polygon mesh with no smoothing information (vertex normals), no uv It is not a high-end, high fidelity 3D conversion file format as many Please take note that there is no 3D file format which is much simpler than STL. Okino has provided one of the very first and still primary STL export conversion systems for close to 3 decades.
It is widely used for rapid prototyping, 3D printing and CAM. STL is one of the industry's oldest (and simplest) 3D file formats created back in 1987 for 3D Systems' first commercial 3D printer.
