Precise dimension modeling

Question Modeling

When you hit "Shift A" , it creates a cube. How do I create a box with precise dimensions such as 9-1/4" x 13-7/8" x 4-3/8" ?

It's impossible to accurately  "Scale" the initial cube to those dimensions, I've tried.

    You can type what you want in the dimensions, make sure you then apply the changes.  You may also want to change your units, since blender uses metric.

    And don't forget to apply the scale after adjusting the dimensions if you plan on doing operations like beveling afterward.

    Also in the Overlays, when in Edit Mode, you can turn on the dimensions for your selections.

    Whap!  That was the sound of me hitting my forehead. :)

    It'd be nice if there was a dialog box upon creation of the object instead of having to go to another pull down menu.

    Maybe Blender could add "dimensions" in the "Object Property" panel. They already have Location, Rotation, and Scale like what's in the the N-panel. [if I were only a programmer]

    Thanks, this is a game changer.  I thought I was going to have to go back to 3DS max and pay the yearly (ug) subscription fees.

    Yeah I'm with ya, I don't know why Dimensions is only in the N Panel. Makes no sense, but oh well, at least its there. Also there are various addons in the Blender Market that add a lot of CAD like functions to Blender and other precise modeling tools. You should check the Blender Market out for sure.

    You can also add a Cube in Geometry Nodes and change the dimensions anytime, not only upon creation:
