CAD2SRF Version 1.3d

Description:

   This tool is used to generate surface triangulations and CAD edge
   curves from native CAD parts using the CAPRI interface. CAD volume
   and face tags are stored for each surface triangle. This code is
   derived from the surfTriCapri code by Mike Aftosmis.

   Two modes of operation are possible: local or client-server.
   The client-server mode allows a server to run the CAD license which
   does not have to reside on the client machine. For example, there
   is no CATIA license avaiable on Linux and Macintosh machines, but
   a Windows server can provide the CATIA license and cad2srf can be
   used on a Linux or Macintosh machine to access the CATIA part via
   CAPRI.

   For client-server mode, an environment variable called CapriServer
   has to be set as follows"

   setenv CapriServer http://my_machine.domain_name:port_number

   where my_machine  = the machine name of the server
         domain_name = domain name
         port_number = access port number on server

   e.g., setenv CapriServer http://machine.nas.nasa.gov:12345

   Output files

   - CART3D surface triangulation with CAD volume and face tags.
     The CAD part and modeler names are encoded in the filename of the
     triangulation as follows: root.a.tri
     where root = partname.modelername.capri.xxx

     partname = name of CAD part with no extensions

     modelername code:

        cat - Catia
        cv5 - CatiaV5
        fls - FELISA
        ide - I-DEAS
        opc - OpenCASCADE
        prs - Parasolid
        pro - Pro-Engineer
        slw - SolidWorks
        uni - Unigraphics

     xxx = 3 digit number for the CAD volume number

     e.g., for a Pro/E part called test.prt with one volume, the triangulation
     filename produced would be test.pro.capri.001.a.tri.

   - PLOT3D multiple grid formatted file containing all CAD edges.
     (filename = root.edg)

   - PLOT3D multiple grid formatted file containing ordered CAD edges
     that satisfy y=0, z>=0 (useful for extracting definition curves
     for axisymmetric bodies about x-axis)
     (filename = root.cur)

   - Vertex uv file.
     A vertex on a CAD edge separating two CAD faces will have 2 sets
     of uv values, one corresponding to each adjacent CAD face. A vertex
     at a CAD node may have more than 2 sets of uv values.
     (filename = root.vuv)

Usage:

  cad2srf [-m modeler] [-p partname] [-angle maxang] [-maxEdge mxedge] [-maxchord small] \
          [-no_file] [-newform] [-efile] [-cfile] [-uvfile]

  cad2srf -help  (to get usage)

  All arguments are optional. If omitted, the defaults in the following table are used.

 Pro/ENGINEER | Parasolid | FELISA | UniGraphics | OpenCASCADE | Catia | CatiaV5 |
     SolidWorks, etc. (cad2srf tested only on Pro/E, Parasolid and FELISA)
