Can someone help? You change the CAD kernel to OpenCASCADE after having created the points and lines - which are thus created with the default (built-in) kernel, and are thus unknown to OpenCASCADE. (Also, BooleanIntersection in OpenCASCADE does not deal with curves - use BooleanFragments instead.) Here's the corrected script: SetFactory("OpenCASCADE"); i=1; Point(i) = {0,0,0,0.5}; o1 = i; i++; Point(i) = {0,1,0,0.5}; e1 = i; i++; Point(i) = {1,0,0,0.5}; e2 = i; i++; Point(i) = {1,1,0,0.5}; e3 = i; i++; //Point(i) = {0.5,0.5,0,0.5}; e4 = i; i++; i=1; Line(i) = {o1, e1}; l1 = i; i++; Line(i) = {e1, e3}; l2 = i; i++; Line(i) = {e3, e2}; l3 = i; i++; Line(i) = {e2, o1}; l4 = i; i++; Line(i) = {e1, e2}; l5 = i; i++; Line(i) = {e3, o1}; BooleanFragments{ Line{5}; Delete; }{ Line{6}; Delete; } _______________________________________________ gmsh mailing list [email protected]<mailto:[email protected]> http://onelab.info/mailman/listinfo/gmsh — Prof. Christophe Geuzaine University of Liege, Electrical Engineering and Computer Science http://www.montefiore.ulg.ac.be/~geuzaine Free software: http://gmsh.info | http://getdp.info | http://onelab.info _______________________________________________ gmsh mailing list [email protected] http://onelab.info/mailman/listinfo/gmsh
