Determining origins of brushes...

[G3mInI]

Ok I have done a lot of searching but have not really obtained the answer I'm looking for. A brush in radiant when selected will give x y z dimensions of the brush. Which is what I need to add a brush via scripting. However I do not see anywhere where the origin is displayed of the brush. I tried bringing up the entities window but no origin is displayed with the brush selected. I even moved the brush around and still no origin is displayed. How can I determine the origin of a brush in radiant ? I have seen in the searches someone mentioning bottom left corner of brush is the origin. If this is true, would I put my cursor on the bottom left point in front view to get the x axis and then bottom left corner in side view to get the y axis? z axis is constant if the origin is located at the bottom most surface.

If someone knows where the origin actually is of a brush, please reply. I need this info to spawn an invisble set of brushes.

Thanks,

Well I do believe I answered my own question. I placed a script_origin in radiant and brought up the entities window to see its origin. Then by using the cursor in the 2d window I found that the actual origin is the exact middle of the bottom surface. Set the grid units to 1 for precise coordinates. Just passing it along if anyone else was interested in determining the origin of a brush.
Models are easy for they always display the origin in the entities window.

Well, you are wrong! The origin of an entity is the center point of that entity, or the center of an origin brush added to it. For a script_origin, the origin point is the center of the red box.

For a worldspawn brush you can see the coorodinates of the upper left corner (in 2d view)--above the selected brush. But, only if you have "ToggleSizePaint" turned on.

ToggleSizePaint = Shift-Q (turns on/off the selection size display)

Models have their own origin points. Like a player's origin is at his feet or a truck's origin may be in the center of its bounding box near the ground.

Alrighty then! Thank you for clearing that up. I have no idea why the z axis was equal to the bottom of the script_origin in the entities window. I must have done something or didnt read it write. I take your word for it though, and thanks for setting me straight.
