In my last post, I showed you how to create a rectangle with a pre-defined rotation. Today, we'll continue working backwards through the Rectangle options and talk about creating a rectangle by defining its dimensions.
Let's say you start the RECTANG command and pick your first point. But instead of picking the other corner right away, you enter D for Dimensions.
Specify other corner point or [Area/Dimensions/Rotation]: D
In that case, you're prompted for length and width numbers.
Specify length for rectangles <10.0000>: (enter a number)
Specify width for rectangles <5.0000>: (enter a number)
Finally, you're prompted for the "other corner point". But because you've already entered the rectangle's size, the only thing left to pick is the orientation. The numbers you entered for length and width were actually absolute values, so you have to pick the quadrant for the rectangle, e.g. positive X, positive Y or negative X, positive Y, and so on.
Try it, and you'll see the rectangle flip about the X and Y axes as you move your mouse around.
If you want to combine the Dimensions and Rotation options, you must remember to enter the Rotation angle first. Otherwise, you'll just end up setting the dimensions again afterwards.
Next up, the Area option.
