    I just started working on my first map and have the main "battle area" mostly completed .


    My question is this, is it possible and if so, how do i "cut" a hole in the floor to allow access to the chamber under it?

    Any help is greatly appreciated


    Thanks

    You should use the Clip or Carve tool for it.
    http://developer.valvesoftware.com/wiki/Reshaping_Solids

    I know, I'm saying you should use Carve (Everyone around me is about to go ballistic!)

    But it's ok when you're dealing with rectangles on the grid. (Ie, whole number grid sizes like carving a floor 1024x1024x64 with a 256x256x256 block, but not one with decimals.) Not ok with cylinders either. Or Spheres.

    Those shouldn't even exist in your map. Hammer's sphere creation algorithm is totally fubar and doesn't work. :|

    Refer to Magical Potatoe's post for details. Just a note though, when you're making any kind of entryway that's not a general box shape like a door frame (ie round holes or archways) NEVER think of it as 'cutting a hole in a wall'. What you are actually doing is constructing the edges of the wall using multiple brushes.

    I hope that makes sense.

    ..and you can use the clip tool to make that one wall into several brushes.

    It's much more difficult to use, but the clip tool is better than the carve tool for a few reasons.

    a) It won't screw up your map like with the carve tool.
    b) You can plan out how your block will be seperated.
    c) It's easy to use if you use good logic and spacial awareness.

    Only even THINK about using carve if your hole will be square.

    I disagree a bit.

    It's very easy to use, you just have to spend a few minutes figuring it out.
    Clicking the clip icon multiple times gives different options (ie:delete left half - red side, delete right half, don't delete either half - both sides white).
    Or using shift-x instead of clicking icon.

    You click one point (use as large a grid size as possible), click second point. choose option (see above), hit enter.

    a) it CAN screw up brush, maybe not entire map, if not cut on grid (brushes will be shifted to spot hammer thinks is best, can have weird results)


    It's also nice because you can clip as many brushes as you have selected if you need to.
    Say you have 3 brushes over a doorway, they are all different sizes, but you want an even strip of trim all the way across.
    You can make 2 cuts (top and bottom of trim) and make trim across all three brushes at once evenly.
