Define arbitrary, logical set of points in 3D(xyz) space, no elements are created.
The set of points can be connected into hexahedrals by using the command createpts/brick as shown in the example and image below.

This point distribution is defined by 8 points along the xyz axis. This differs from createpts/brick/xyz/ which generates a logicially rectangular distribution defined by 2 points at the mininum and maximum corners of the domain and then generates connectivity for elements.


quadxyz/ nx,ny,nz / &
    x1,y1,z1/x2,y2,z2/x3,y3,z3/x4,y4,z4 / &

nx ny nz specifies the number of points between the 1st and last point along each X, Y, Z axis. The number of points will be 1 more than the number of spaces.

x1,y1,z1/x2,y2,z2/x3,y3,z3/x4,y4,z4 are the coordinates counter clockwise around the bottom quad face.

x5,y5,z5/x6,y6,z6/x7,y7,z7/x8,y8,z8 are the coordinates counter clockwise around the top quad face.

createpts/brick/xyz/NPTS NPTS NPTS/1,0,0/connect

Create a 2x2x2 point distribution (mesh object with 0 elements). Then use createpts/brick to create connectivity. The result is a single hex with 8 points as shown in the image.
