I feel that the copycat tool should work like the copy/paste tool in GMOD, allowing you to snap items to a grid/snap items to other items. Lets say you want to put a bunch of cubes in a line. You have to spawn them one by one and move them into place, i think it would be better if we could copy a cube, and have an align to grid and an align to object based in its grid as well.
oh so you want to be able to copy multiple items and once and copy and place them all as the same. the devs will do that, it is what the item grouping and Multi-selection is on this card, https://trello.com/c/oLKVaBp0/111-advanced-condo-build-mode
More that id like to be able to copy things directly snapped to a grid so i can line them up easier.
