• -filter : if set, abstract nodes like a layer filter in CATIA V4 modelsare used to filter the geometry contained in the given CAD model; CATIAV4 models, for instance, always contain the standard layer filters ’ALL’ and’LAYCUR’;if the specified filter is not present in the model, all contained geometry istranslated instead» Translation properties• -ascii: write output file in ASCII format; default is -bin; set to ASCII, if outputformat is VRML2 or OSG; set to ASCII, if output format is STEP, IGES, orVDAFS;• -bin: write binary output file; set by default, if -ascii is not used; ignored,if output format is VRML2.0, OSG, STEP, IGES, or VDA; set to binary, ifoutput format is CATIAV4;• -nurbs: write geometry as trimmed nurbs; if set, all tessellation parametersare ignored; if not set, output is tessellated geometry using the tessellationparameters; is ignored, if output format is VRML;• -curves: translate free space curves; if not set, space curves are ignored• -childColors: if set, the lowest color in the CAD model hierarchy is used;example is to use face colors instead of layer colors (CATIA V4); if not set,the first color found in the CAD hierarchy is used;• -sew: if set, adjacent sheet surfaces will be detected and sewed together;sewing works with a tolerance dynamically adopted to the given geometry; iftwo adjacent surfaces have different orientation, one will be reversed to bothhave the same orientation; sewing works with -nurbs and when tessellatingthe geometry, in the later case ensuring the adjacent surfaces are equallytessellated along the common edge;• -tq : defines default tessellation quality levels (tessqual=1,..,4): thetolerances surtol and nortol are always ensured; the tessellation quality level,improves the quality of the triangulation in terms of regularity of the triangles159
