The Vectorworks program imports Stereolithography (STL) files, which are widely used for 3D printing, prototyping, and manufacturing. Polygon mesh objects import into a Vectorworks file as mesh objects.
To import an STL file:
Select File > Import > Import STL (3D only).
The Import STL File dialog box opens.
Select the file to import, and click Open.
Alternatively, click the file to import and drag it into an open Vectorworks file.
