Sketch a rectangle starting with its center point.

Shortcut: r

  1. Click Center Point Rectangle tool icon to set the center point, click again to set a corner.
  2. Or click and drag from center point to corner and release.
  3. Optionally, immediately after the rectangle is created, input a numerical value (or type "=#" to input a variable) for the length and press enter, then input a numerical value (or type "=#" to input a variable) for the width and press enter. This dimensions the rectangle without having to use the dimension tool.

To input a variable in any dimension field after the geometry is already sketched, the equal sign (=) is not required. Type "#" to input a variable.

Hold the ALT key while sketching to constrain two rectangle sides to be equal (resulting in a square).
