• -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=0,..,4): thetolerances surtol and nortol are always ensured; the tessellation quality level,improves the quality of the triangulation in terms of regularity of the trianglesand approximation to geometric details; a higher level typically also increasesthe number of triangles;· tessqual=0: use tessellation parameters -gridMode -triMode -edgeQLevel-chk_gen_pcurves -narrow_reg_repair -edgeSagTol as set or their defaults;· tessqual=1: gridMode=AF_GRID_NONE;triMode=AF_TRIANGLES_ON_FRINGE_ONLY; edgeQLevel=_MEDIUM,chk_gen_pcurves=1; narrow_reg_repair=1; -edgeSagTol=0.5;· tessqual=2: gridMode=AF_GRID_TO_EDGES;triMode=AF_TRIANGLES_ON_FRINGE_ONLY; edgeQLevel=_MEDIUM;chk_gen_pcurves=1; narrow_reg_repair=1; -edgeSagTol=1.0;217
