How to Convert 3D Models into STL Files
Solid Edge ST6 – ST8
forwardApplication Button > Save As (opens dialog box)
forwardFrom the Save As drop down menu, select STL documents (*.stl)
forwardSelect the Options button from the Save As dialog box
forwardAdjust Conversion Tolerance and Tolerance Units (millimeters recommended)
The lower the conversation tolerance, the finer the tessellation
forwardAdjust the Surface Plane Angle (dependent your desired surface smoothness)
The lower the surface plane angle, the greater the accuracy (noticeable in small details)
As a rule, the finer the tessellation and the greater the accuracy, the larger the size of the STL file, and the longer it takes to generate it
forwardUnder Output File as: Check Binary
Binary STL files are much smaller than STL files saved in ASCII format
forwardClick OK > Save
Tip: Review the controls for exporting STL files in Solid Edge here.
Note: Solid Edge is capable of creating individual STL files from the components of an assembly, but this functionality is not built into the program. It is achieved through the application programming interface (API), using Visual Basic scripts. This solution does not enable a visual preview of the polygon mesh before saving the STL files.

Solid Edge (Older than ST6)
forwardOpen model and select File > Save As
forwardSave As Type >STL
forwardOptions > Conversion Tolerance: 0.0254 mm for FDM; 0.015 mm for PolyJet
forwardSet Surface Plane Angle to 45°
forwardSelect Binary type and OK
forwardName and Save STL file
Note: Solid Edge software from Siemens PLM (formerly USG) supports STL output at the core level, enabling you to save both parts and assemblies as STL files. However, when saving an assembly, all of its components are included in a single STL file.
