Help...our local senior center has 2 American snooker tables & 4 eight ft. Gandy & Brunswicks. They're building another center, probably 18 months out, with a smaller size billiard room. Is there any free program/software out there that I can utilize that let's me put in room dimensions, table dimensions, and move the tables around that show's dimensions? They think we can do 2 snooker / 3 regular tables in the alloted space, what I see gives virtually no seating room. Thanks for any help.
