OK, so I installed basejump and it worked for about 5 minutes before I broke it:
- new civil3D drawing (ANZ profile)
- mapcsassign (AMG-56)
- mapconnect (just the middle bing maps option : Aerial
The aerial image came up no problems and looked promising, but when I closed this drawing and tried to bring in an aerial in another drawing, it just wouldn't "add to map". Now it doesn't work with a new drawing either.
Curiously, it still works with my Map3D. If I bring a Map3D drawing with basejump connection into Civil3D it works fine.
