+  **TYPEDEFS FOR MESH AND MODEL ENTITIES**
+
+------------------------------------------------------------------------
+
+ 
+
+A mesh object (actually a pointer to it) in the interface can be
+declared as
+
+ *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;
