Dear Chang,

I am not an expert to comment on the questions (1) and (2) you have listed
below. However, regarding question (3), I can comment.

STL files generated from CAD software can be manipulated by other software.
If you have SolidWorks, you can try out STL Import for SolidWorks
( to import a STL model into
SolidWorks directly as a solid. You can then perform all sorts of operations
on the imported model, as you would on any SolidWorks part document.

Just last week, we released MeshWorks for Rhino
(, which provides useful mesh
manipulation utilities such as hollowing, stitching, filling holes, etc.
Rhino already has a STL import/export interface. So if you have Rhino, you
can use it to manipulate STL meshes among other kinds of meshes.

Hope this helps.
