Create Volumes (bricks) based on the 8 corner coordinates with Python

Dear all,
I would like to create volumes (bricks only) with a Python script based on the 8 corner coordinates.
Is it possible to create brick volumes only with coordinates?
Many thanks.

Hi Stefan,

The Cubit command language doesn’t have a method to create a brick based on the corners. If I really wanted this in python, I would create a function. Here is an example just using the length, width, and height specified as x, y, and z values.

def my_brick(x, y, z, center):
    cubit.cmd("graphics off")
    brick = cubit.brick(x, y, z)
    cubit.move(brick, center)
    cubit.cmd("graphics on")

It would be used as follows

import random
for i in range(10):
    random_x = random.randint(1,10)
    random_y = random.randint(1,10)
    random_z = random.randint(1,10)
    my_brick(random_x/2,random_y/2,random_z/3, [random_x, random_y, random_z])

I turned graphics off and back on to reduce any graphics flashing while creating and moving the objects. That is not necessary, but can be nice. Converting from x, y, and z lengths to distances between the given coordinates should be fairly straight forward.
