I have a user who keeps getting this error when trying to cut cross sections. He said it was happening about 75% of the time but now it is happening all the time. It is not just one project that this happens on. I'm going to try to re-install Microstation and InRoads.
Microstation v8i SS3 update 1 08.11.09.357
InRoads v8i SS2 08.11.07.494
Edit- I've noticed that the existing surface being used for this project is 154 mb! I've never worked with a surface that large and everything I try to do with this surface is slow. I'm trying to delete half the surface to see if that makes a difference. I've placed a fence over a relatively small area (still hundreds of features) and deleting features inside the fence. Computers been crunching for 15 minutes and they still have not deleted. Intel Core i5 processor with 4 gb of RAM. I'm going to try this on a PC with an AMD quad core processor and 8 gb of RAM to see if it operates any better.
