I know the carve tool causes lots of compiling problems, but I don't know how to make things like doorways without using carve. Can you help me with that?
Use clipping rathjer than carving. Keep selecting the clipping tool until the selected brus is outlined white on both sides of the clipping plane. Now you can clip without losing parts of the selection. Remember not to go too small on the grid <!--emo&:)--><img src='http://www.unknownworlds.com/forums/html/emoticons/smile.gif' border='0' style='vertical-align:middle' alt='smile.gif'><!--endemo-->
Ok, I found some tutorials for you <a href='http://collective.valve-erc.com/index.php?doc=1046748955-93414200' target='_blank'>Here</a>, and <a href='http://collective.valve-erc.com/index.php?doc=1026040451-89982700' target='_blank'>here</a>. Those should be something to point you in the right direction.
In general, the first step to making a hallway is choosing the shape of the doorway. Usually I will just cut the wall brushes in half with the clip tool set to leave both sides. (the setting where both sides of the line are white) Then I will resize those pieces into the general shape of the doorway. Most of the time it is useful to start out by shaping the wall around your doorway into a box and using additional brushes to fill in for the shape you want. Read up on those tutorials though... they do a much more in depth job of explaining this.
You can use the vertex editing tool to create any and all doorways brush by brush(to halve the workload: doors are usually symetric, make one half, texture it. Turn on texture lock(tl icon in hammer editor) and mirror it).
Usually, if I wan't a slightly complex doorway, say rectangular with a half-circle at the top(IE arch), I will make a simple template by making a block and a cylinder, slicing the cylinder in half with the clip tool and then rotating/flip everything in place(ctrl+m for scaling/rotating/moving numerically). Then just turn of texture locking and make a block brush and vertex edit to fit outside the "template" and the surrounding walls. If possible keep the top and bottom flat, select and hold shift and drag to duplicate it, if you made the top/bottom flat you can flip it up side down and put it above/under the previous brush and you only have to edit 2 vertices to fit it in place. Keep fitting brushes like this until you are done, if there are symmetries use them(IE a rectangular doorway with a circular top will can be done by creating one half and mirroring. A circular doorway can be made by creating one eight and mirroring/rotating).
Hope this makes some sense, I'm too tired to write it properly...

Happy mapping,
