RE: STL to IGES convert

Dear All
The best way to get from an STL to a surface (iges) file is to fit surfaces
to the triangle model using a Reverse Engineering package such as CopyCAD
(www.copycad.com). This will allow you to create an accurate surface
representation (<0.1mm) and iges output.
Give me a call if you need any more detail.

Dear All,

I'm very sorry to announce that our Magics RP doesn't support IGES export of
an STL-file.
The reason is, as Adrian already mentioned, that each triangle will be
exported as a single unit. This is because the geometrical information is
lost in an STL-file, the computer doesn't know anymore that some groups of
triangles are forming (for example) a plane or cylinder. The results are
pretty big and useless IGES-files.

Magics Rp is (currently) only able to export sections and parting lines as
IGES-polylines.

Kind regards,

Pieter

Dear List, dear Paul-Henri

MagicsRP from Materialise allows to export a STL-File as IGES.
But I don't think this is very good idea, because you will get the
triangles from the STL as small patches. This will increase the file-size...

If you need good quality surfaces, you must do a >reverse engineering< of
the part.

Regards
Adrian
