Help! I can't cross walls with dolly camera.

I am using 12.4.0.23 and need to move from room to room with the dolly camera but the camera bounce from the walls without crossing it.

Yeah, not sure if there's anything you can do about that. Funny though, you can BACK out through the wall, but not moving forward.

Is there any work around? I need it for my presentation. also can you tell me how to import DWG files, I get a message that the file doesn't exist.

3D Settings dialog box.
Turn off Camera Bumps Off Walls.

Sweet, always learning something new around here. :p
