HiWe sell furniture online. We want the ability to allows customers to specify their floor dimensions and then drag/drop our sofas onto their floorplan to see how much space our sofas/tables take up.I dont want anything complicated, just a rectangle that the user specifies the dimensions of, and can then drag up to 10 shapes (our range of sofas/tables) into the rectangle.How can this be done? Has someone done similar before?Thanks
