Exchange Random

It's good to have a standard routine to set up blocks. In that case it's easy to make your drawing more vivid by using 'Exchange Random'. You will have to make two selections of blocks. The first selection are the blocks in your drawing. The second selection are sample blocks, different types of blocks. As soon as you confirm the second selection the command will exchange every block in the first selection you make with a block randomly picked from the second selection you made creating a variety of blocks. The blocks are completely random but you can influence the result. When you select blocks named "block A" and "block B" once and "block C" twice, the command will place about twice as many blocks called "block C" then the blocks called "block A" and "block B".
