Hi,
I use Sketchup making seating arrangements for theater seating and banquet seating in a convention hall. To do this now I have my chairs and tables in groups and I use the copy tool to place them out evenly in one dimension and then copy that array in the other. What I would like though is a tool similar to the tool for creating tables in word (see image). What I imagine is a tool that lets me draw a shape, either a simple rectangle or even better, a random shape that the plugin would populate with my objects according to my specifications.
The tools I have found so far distribute objects either randomly for such things as people or trees, or perfectly even. For my theater seating however, I put my chairs next to each other along the row but leave a space so that people can reach the chair and sit down in the other axis. (see image)
Is there such a tool out there?
