the size-properties describe the shape of an object in 3D. X, Y and Z are axis used to place an object on a point in space.
Show axis example
The X and Y axis define the position on the ground, as seen in the picture below. They’re coloured red and green.
Here is a cube that tells us its position on the X and Y axis while it is moved around.
The third axis, Z, describes the height of the item in space. It’s coloured blue.
You can play with this example scene to get a better understanding of the three axis.
The building blocks in CoSpaces use same concept of axes as shown in the example. The X, Y, and Z represent the cube’s own axis in space. When you change the X, Y and Z values you adjust the width, length and height of the cuboid respectively.
I hope this made the use of axes in 3D more clear to you! Let me know if there’s anything left unclear.
