Making brush based ladders. Help?

I'm getting along with some of the basic construction of my level and I need some ladders with heights that aren't compatible with the height of the ladder models included with hammer. I read a few tuts that kind of talk about making your ladder out of brushes, so I did that, and put the info_ladder_dismount at the bottom and top of the ladder, and put the func_usableladder at the top and bottom of the ladder, but it doesn't work. I read about func_ladder brushes, but there are none listed in the list of entities after i create and texture the brush that's mean to be the func_ladder. This is an hl2 map, if that makes a difference.

I know less than I thought I remembered about mapping.

i make my brush based ladder with the ladder texture. (in CSS maps) I'm not sure that it works in HL2 though.

Yeah, for hl2 the ladders are completely unnecessarily complicated. If you've got your brush ladder set up, encase it in the "clip" material, but make the front, sides, and top exactly 1 unit larger than the ladder. Then, set up your useableladder so that they are 1 unit away from the ladder, the bottom is 1 unit off the ground, and the top is 1 unit above the edge. At the bottom, have 3 info_ladder_dismounts, all 1 unit off the ground. Place one exactly 8 units in front of the dismount, the other two 8 units to the sides. At the top, have 4, all 1 units above the edge 8 units from the useableladder in all directions. Look at this vmf for reference (scroll down to where it says "download for free with FileFactory basic).

Thanks guys, I got it working now.
