Hi All - Im trying to overlay a .dwg file from and engineer and Im having trouble. (auto cad LT for MAC)

I go to INSERT and select OVERLAY and select the file.

It then takes me to the model screen and asks me to insert an insertion point? How do I know where this is?

Sorry for the silly question - I haven't done this before.

I have created a landscape plan on top of the civil drawings initially provided to me - They have updated these civil drawings and I need to check the changes in the road design.

Thanks so much!
