PMeshObj mesh1, mesh2;
 

Mesh entity types are as follows:

 /* Mesh Regions */
 PMeshRegn reg1, oreg, regarr[50];
 

 /* Mesh Vertices (nodes) */
 PMeshVert vert, *verts. vert[20][30];

 /* Mesh Face */
 PMeshFace rface;

 /* Mesh Edge */
 PMeshEdge face_edges[4];

 /* Type of mesh region or element       */
 /* This is an enum decl which can be    */
 /* TET, PYRAMID, PRISM, HEX or RDELETED */
 ElType reg_type;

 /* Type of mesh vertec */
 /* Can be VIGNORE, VPARENT, VDELETED */
 VType vert_type;
 
 

Geometric model entity types are:

 /* Model entity - can be a region, face, edge or a vertex */
 PGeomEntity  gent;

 /* Model region */
 PGeomRegn greg;
 

 /* Model face */
 PGeomFace gfaces[20], **gfaces2, interface;

 /* Model edge - not used at this point */
 PGeomEdge geds[], *gfeds;

 /* Model vertex - not used at this point */
 PGeomVert gv1, gv2;

 /* Type of model entity - can be GREGION, GFACE, GEDGE, GVERTEX */
 GType geomtype;
