Johannes Kebeck, Technology Specialist for Virtual Earth, has just released some drawing tools to make it easier to add lines and shapes inside of VE. You can find them here.
It’s shame that something as simple as drawing basic shapes in still such a chore in VE — even this solution requires a bunch of code. Google Earth has them beat badly on this front, but they continue to make progress.
Update 6/14/07: These drawing tools were already in VE – they were just hard to find. You have to “add pushpin”, and then change it to a poly. This is simply UI tools for drawing for the dev community.
