You can also use [ and ] to rotate objects by smaller increments than 15 degrees.

Hmm, I can't get that to work. Someone told me about those keys. I guess I should have tested it before posting here.

if you use the number pad on your keyboard ! the one on the far right ! use the keys - and + makes the blocks/objects
spin around, instead of just 2 places...
think this is posted above somewhere...

Its posted in the valleydiscussion

Anyone know how to delete individual items?

The only way im able to work with them is using undo or deleting and replacing the block where they stand...
...not practical sometimes.

Choose the item/object mode (the tree icon) then hold "X" and click the object.

I was being dumb, even the eraser icon works...

thanks eyebo
