Saving Files as STL Files
You can save part and assembly files as STL files using binary or ASCII
format. Binary files are smaller than ASCII files, but they are not supported
in some other systems.
If cross sections are shown in the model, they are not shown in the
STL file.
The STL file
always uses meters for the unit of measure. All measurements from the
original file are converted into the equivalent value in meters in the
STL file.
To save a file that you received from another user as an STL file, the
sender must have set the option to give you permission. See Creating SolidWorks eDrawings Files.
To save files as STL files:
Click File,
Save As.
Set Save as type
to STL Files (*.stl).
Type the File
name, then click Save.
In the STL Export
Options dialog box, under Format,
select Binary or ASCII.
Click OK.
