+> **_RZBRICK_**
+
+Builds a brick mesh and generates a nearest neighbor connectivity matrix. This
+command is similar to the rz command format except here we have symmetry flags
+to input. A second format specifies that a mesh be created and connected.
+
+**xyz **specifies Cartesian coordinates.   
+**rtz **specifies cylindrical coordinates.   
+**rtp **specifies spherical coordinates.   
+ni,nj,nk number of points to be created in each direction.
+
+xmin,ymin,zmin minimums for coordinates.
+
+xmax,ymax,zmax maximums for coordinates.
+
+iiz,ijz,ikz&nbsp_place_holder; if =0 then mins and maxs are used as cell
+centers if =1 then mins and maxs are used as cell vertices iirat,ijrat,ikrat
+ratio zoning switches (0=off,1=on)
+
+xrz,yrz,zrz ratio zoning value - distance is multiplied by the value for each
+subsequent point.
+
+name name of pset containing starting point number
+
+isym,jsym,ksym symmetry flags - not documented
