Circle to Block

Circles are very basic entities and can serve as placeholder. If you want to make you drawing more vivid drawing you can use the 'Circle to Block' command to place blocks on the position of the circles. The position is not the only geometry the command can use. If you want you can relate the scale of the block to the radius of the circle. That way the new blocks have same proportions as the circles you selected. If you don't need the circles anymore you let the command erase the circles straight away.
