anyone willing to walk me through building TB from source?

Ive never built from source or anything in this order.

Downloaded Visual Studio and everything, but I think I dont have the proper versions.

Got to this point and had to give up.

CMakeError.log just goes on and on like this:

"Compiling the C compiler identification source file "CMakeCCompilerId.c" failed.
Compiler: cl
Build flags:
Id flags:

The output was:
The system cannot find the file specified"

command prompt is telling me about vcvarsall.bat, which has to do with visual studio?

:cries in corner: 

Is there any chance of seeing a new beta release any time soon? It's been a while since the last one, and although I imagine the goal might be to hit full release with the next update, there have been a lot of changes since the last one. For some of those, it's fixing bugs that I myself created and would rather like to enjoy the fruits of having the fixes.

I know I could compile it myself, but as I understand it the process is quite complicated due to the need to compile several different things seperately and so on. I'm not really that level of user unfortunately, so yeah... It won't kill me if I have to wait until full release for TB2, but a new beta would be nice. 

Agreed on the build being complicated. Tried to tackle it and had to give up.

Fortunately, Ericw came to the rescue with a recent build.

https://ci.appveyor.com/project/kduske/trenchbroom/build/2.0.0-appveyor-65/artifacts

now, GO MAP. or...yknow. hangout. up to you. 

Still working on TB, but at a very slow pace. I'm swamped with RL things. 

It's totally understandable that you're busy SleepwalkR, and it's even easier for me to be cool with that thanks to the ericw and the link mukor posted :D 

Is it okay to submit bugs that are from that interim build that was just posted? I found this but I'm not sure if it's okay to create an issue for a 3rd party build of the program. 

I'd say submit the bug, I'll take the blame if it's an invalid bug for some reason ;)

(That build I made is the current latest code from release/v2.0.0 and it's built by TrenchBroom's CI system, so there shouldn't be anything weird about it.)

FWIW I think I hit that bug of things going off grid as well, haven't had a chance to investigate it though.. 

Does anyone use TB on macOS 10.8 or below; would you care if TB required 10.9+? 

Personally, I try to avoid using 3-point clip whenever I can. I find it not very intuitive and often end up clipping out the part that I wanted to keep. It's quite common for me to have to do multiple tries to find the correct camera angle that will make the clip tool perform like I intended. In many cases it's faster to just do it in vertex mode. 

Hopefully this will help de-mystify what the third point is for, at least to the point where you understand it as well as I do (I'm moderately sure this is all it can do).

Here's a standard, 2-point clip:

Then... Bam! 3rd point:

Try it yourself. Drag the 3rd point around and watch as the angle of the clip changes. Obviously this is a very basic example, but the general idea of it is that you can change the angle of your cut with this method.

I find it most useful for when TB doesn't "get" what you're trying to do because the 1st and 2nd points are too vague, since you can easily direct exactly how you want your cut to work using it.

Another cool trick is placing all your points on a flat plane, like so:

The third point tells TB that you actually want a horizontal cut, so you can easily perform that style of cut.

Here are some more fun cuts:

Hopefully that helps people figure out what the 3rd point is for. 

Thanks Pritchard, that does help clear things up! 

Bonus points for knowing the shortcut if you wish to use an existing face as a clipping plane! It'a in the manual ;-) 

 

A good tip is...unless you need another brush to snap a clipping point to, isolate the brush to be clipped.

If you try to place a clipping point at the edge of a brush where it meets another brush, sometimes itll get placed on the other brush.

I switched my "Hide" "Isolate" and "Unhide" to H I and U for this and other reasons. 

Thank you, Sleep, for implementing issue 1465 "Always show edges of selected brush" and 1460 "inspector keys open inspector window when closed"

Didnt even consider theyd be in the build eric provided so they were a very pleasant surprise to run into.

"Oh hey thats me!" 

I made some good progress on 1499 recently and things are looking better. Hopefully I'all be able to provide new official builds soon. 

Is going to be magnificent. 

Try loading Shamblernaut's RJ5 map in the latest TB2 beta! 

If you have found a bug, then create an issue report plz. 

i'm learning the very basics of brush work
it's possible to move clipping points with arrow keys, like moving vertex points in the vertex edit mode?

or i just have to drag the orange dots?

can i snap the clipping points to edges and vertices of other objects? or the only snapping is to the grid?

i'm better off in general using CGS substracting if i want to avoid brushes with intersections?

another very basic question:

when you are resizing a face with non-parallel convexing lines (i don't know how to say it) like this:
http://imgur.com/a/oe08L

in one point the lines intersect. is there a way to resize until the two vertices intersect in a point (like a cone) or a line (like a wedge)?

btw i get the 3-point clipping. you need three linearly independent points to define a plane, and the editor makes a "guess" when using 2-point clipping to define a plane. it's like slicing a brush with a cutter 

don't blame tb2 for my shitty maps =P 

Be sure to check out the help file in About > Help for the basics on a lot of your questions.

If you still have issues post back! 

ok...
i quote from the help

"Note that you cannot change the number of faces of a brush by with the resize tool."

i missed that enterely. i think it might be useful. perhaps it's unnecesary, i don't know.
also, it's 'converging lines', that's what i meant.

--

"Alternatively, you can add two clip points at once by dragging with the left mouse."

and

"In the 3D viewport, you can only place clip points on already existing brushes, whereas in the 2D viewports, you can place them anywhere."

now i don't need to move clip points with the arrows.

--

CGS substracting is a question of the type of "is good practice or not?"

--

it seems that i can't snap directly to objects, so it's better to snap brushes to the grid and zoom if they are separated by 1 unit.
and using clipping, CGS and vertex. 

Glad to see the Help file ...helped!

As far as subtracting goes, I think it has come a long way...TB2 handles it fairly well. One thing I do is if I have an odd shape I plan to subtract, I will cut the brush into as small of a square as I can around the subtracting brush. That way there isn't so many crazy things going on after the operation!

For things like basic shaped hallways and such it it probably best to just create the brushes to form said opening. 

I can never seem to do arches with any consistency. It's not that the end result is bad but I just seem to do mine by trial and error. How do other mappers approach creating an arched doorway? I am using TB2 and would love to how others approach this.
