Hello Justin,

you can use the standard SlaToIv program to translate from stl format
to inventor format, which you can view by using the ivview program on

     SlaToIv - convert an SLA format file into an Open Inventor 2.0

             <infile> <outfile>

     SlaToIv converts an SLA formatted file into an Open Inventor 2.0
     Copyright 1993 by Iowa State University.

     <infile> Specifies the name of the SLA file to read and convert.

     <outfile> Specifies the name of the Open Inventor file to use for

Be aware that this program does not do any data reduction: the
vertices of the triangles will be all several times in the inventor

If you want to do a better translation with data reduction (to get a
better interactive response from the ivview program) you can use the
ADMesh program from Anthony Martin.
ADMesh can write STL, VRML, OFF, and DXF files and a lot more, see for
your self. The VRML file translation will reduce the data by using a
IndexedTriangle elemnt, so that each vertex is only included once in the
The VRML file can be viewed by a number of applications, including the
ivview program.

ADMesh can be obtained via http from:

I hope this info helps and wish you succes!
