How do I create and set the depth of a cube in blender 2.80? In edit mode I click on add cube, I click on the screen to set the location of the 3d cursor. Then I click and drag to create a rectangle shaped cube.
But how do I set the depth to be the same as one of the other sides ? Or how do I define the depth at all?
I am not seeing any properties relating to the size of the cube being created. The cube created for me is very thin rectangle like a plank of laminate flooring and I cant work out how to make it thicker and square like a wooden post.
Creating a square cube or post seems such a basic thing and yet it stumps me.
If you are using the Edit Mode "Add Cube" tool, you should get handles that you can use to modify your cube visually:

After creating the cube (by dragging the left mouse button), orbit around the cube by holding down the MMB middle mouse button, then just grab a face and pull it in the desired direction. I'm not aware of a way to use these handles with exact numbers.





However, if you want to create a new cube and set its dimensions, I suggest adding it in Object Mode with Add > Mesh > Cube. In the "number" panel (N) you will be able to set its dimensions precisely.
