If these are the only spaces you have available, (no garage, no possibility of tearing down a wall, etc, or moving again!, lol)...
Some people with limited space have put a table against a wall as an extreme. This table then is only useful for drills and practice shots.
You should draw the table in, and then draw a border around it at a 60" distance from the playing surface. The border should have rounded corners with their center at the corner pockets. This will represent the end of the cue for a 58" cue + a 2" backstroke. Then draw a few more borders using the same technique but adjust the cue length to represent using a short cue. Make the table and borders all one "assembly" on the CAD program, so you can move it around as a single entity.
Do this for a 7' table first, and then an 8' if you like what you see.
Then, move it around your space, considering your openings, to see what location would give the optimal space for "most" shots.
Thanks, I'll try that to get a better idea of what I'm looking at.
I probably *could* remove the walls with the archways. The one on the left opens up to the foyer. I have a feeling that one may have lally poles hidden behind it though :S I hope I'm wrong about that.
The archway at the bottom goes to the dining area. Removing the walls would open up pretty much everything except the kitchen... It's work I don't want to do, but am considering now lol. I *really* want a table :|
