This is some code for CTCA
{"classname":"Block","targetname":"wood_10x120","properties":[{"key":"x","value":484.6509704589844,"type":"float"},{"key":"y","value":-378.686279296875,"type":"float"},{"key":"r","value":90,"type":"float"}]}
Notice the X/Y values can be exactly placed. However, the "wood_10x120" appears to be a definition and the size/height are fixed. I tried to change it but it didn't work. I meantioned this to Joey but I think it may not be available to change these parameters. We wil see...
