The rotation commands allow you to type in the exact amount on the command line. I recommend the non-visual rotate for these operations, which you find by right-clicking :CC2ROTATE:.

Or, if you have a Norwegian keyboard, you'll actually have an 'Æ' key on your keyboard :)

Check your sheet order. Your floor is most likely on a sheet that appears after the symbols in the list. Use the List command from the info menu to check which sheet your floor and the symbols you are trying to place are, and adjust the ordering accordingly. Remember that stuff on sheets at the end of the order appears on top of things from sheets higher up.

It is also possible that the sheet order is wrong and your symbols go to the wrong sheet. But this will also be revealed with a use of the List command. If the symbols are on the wrong sheet, use :CC2MCHANGE: on them to move them to the right one.

In this session, I'll play with trains. We'll lock at creating the track, as well as create a nice railroad car suitable for a battlemap.

As usual, you can find the time in your local timezone in the left sidebar. Visit the stream over at YouTube to join in on the chat.

Thanks @Wyvern . It is now in the atlas.
