    How would one use a block (cylinder for example) to cut out the shape inside another block.

    I am new to Hammer, so sorry if this is too obvious for me to see... :(

    Hopefully you understand what I'm asking for...

    Doing that with a circle will make some HORRIBLE brushes, just make it manually with the arch tool or the vertex tool.

    NO

    FOR THE LOVE OF ALL THAT IS SACRED NO!!!

    Do not carve! Never, ever, carve anything more complex than a box into another box, and even then you're probably better off using the clipping tool. Carving will choose for you how it cuts up the brushes, and it'll almost always choose horrific awful ways. I deliberately linked to arch tutorials because that's the best way to make a circular hole.

    I repeat for emphasis:
    NEVER CARVE ANYTHING MORE THAN A BOX IN ANOTHER BOX

    Carving, vs clipping tool manually. One can be repositioned easily, the other can't

    The carve tool is a perfect example of a great idea implemented horribly.

    Can we just ask Jill to get someone at Valve to remove the carve option from Hammer? Should be a relatively simple fix assuming there's anyone working there who still knows where to find the source code.

    There are still "some" applicable uses of it...

    Nothing you couldn't manage on your own and get better results with vertex edit.

    Carve is needed to make some curved geometry with instances

    There is a thing that uses carve you can't do without. I believe Exactol was mentioning it.

    Maybe just add a warning when you click on the carve tool: "Warning, carving a brush can cause many issues. Unless you are aware of what you are doing, we suggest you do not use this tool."

    Sadly, much people think they are aware of what they're doing just because they can read the tool name.

    The level of understanding needed to know why the carve tool can break things is far beyond the level of understanding needed to use the carve tool. It's a reasonable mistake that many of us have made, and some of the reactions in this thread are blown way out of proportion.

    Simple shades like squares are fine (Thats carving a square out of a square) but anything else can have problems

    That, and people keep making tutorials that recommend using it; newbies wouldn't even know what it is or what it does otherwise (which would be a good thing because only advanced users ever have a use for it).
