There's another alternative as well. If you're designing your map to be used only in Aleph One, and not Infinity, you can leave those lines there, as Aleph One can almost certainly handle it. To work through this problem in Visual Mode, wherever you have big views and big rooms, double-click on some lines and uncheck the box marked "transparent." This will make the area viewable in Visual Mode (although not in full visual splendor), and when you're finished working, make the lines transparent again. Goran taught me this several years ago, and it works wonders, allowing the creation of very complex areas. The only problem is that you have to make all the lines transparent again and open the map in Aleph One to see what complex areas really look like.
