The BOX command is one of the many AutoCAD tools that enable you to create 3D solids. You can access the Box tool from the Modeling panel of the Home tab. It will prompt (by default) for two corners (just like the RECTANGLE command) and a height.
You could save some clicks if you draw the box exactly where you want it to go but maybe you don’t know that yet… After all, this is conceptual design and you may not know where you’re going until you get there. For now, I’m just going to draw the box anywhere in 3D space and then I’ll select the Box to access its grips.
- Creating a 3D solid box similar to creating a 2D rectangle with height.
