I have divided my site into different materials using subregions (now not my favorite, but already done for this project), and I'm having trouble with one of them. I want to change the shape of it, but every time I try, I get a 'failed to triangulate' error. I then tried just going into edit boundary mode and immediately clicking 'finish sketch' without changing anything, but it still failed to triangulate. So I decided just to delete the subregion and start again on that bit, but when I try to delete it, I get that horrible 'serious error has occurred' message and I can't delete it. I've noticed that there are a few places where the subregion no longer meets the grade of the main topography - like someone has lifted up the edge of a blanket. This is presumably the problem, but I have no idea how to solve it when I can neither change nor delete the subregion. Has anyone else seen anything like this? Is there anything I can do, or am I just stuck with the wrong sidewalk shape? I can post the file if necessary. Post edited on 2006-03-28 14:50:44

Subregions are fragile little things, those are the two errors anyone who tries to use them extensively gets... here are some things that can muck them up: -Having two shapes when editing a single region (so edit it, then zoom to extents to see if there is an area highlighted that you dont know about) -Ovelapping lines, intersection lines (check all corners) -The little Revit nomes on their lunch break (try again later) -Complex shapes (try dividing them up and doing one part at a time) Or as a bit of a last resort, change the shape into a simple square and see if that works. I've had those problems before and there are workarounds.. you just have to figure them out...

Thanks for your reply. I've had sucess with those tactics when I have trouble creating a new subregion. However, I seem to have somehow created a subregion which is un-creatable due to its complexity -- it's already there, and I really need to change its shape, but I can't edit or delete it. I tried the Edit Boundary, then change it into only a small simple square, but that also got me a near-fatal error. I don't want the gnomes to be in charge of my sidewalk!
