there is a program called librecad that made it easy for me to enter the shop equipment footprints and to rearrange the layout
every time i try one of these programs the dreaded learning curve makes me hesitant
but this program has a command line so it is super easy to create a block for each piece of equipment and then use those blocks on the master floor plan

now you have a rectangle and can then add text with just a couple clicks save it to library/shop directory and librecad will see it
i probably could have done things by using scaling rather than dimensions but that will have to wait for next time
