Not sure about the vertex functionality in 2d modes.

Take a search through the Git page here: https://github.com/kduske/TrenchBroom/issues

As far as grouping brushes together and making them entities:

Select the brushes you want and press Ctrl + G to make them a group. Now double click the group and you will see all brushes except for your group highlight blue. Now you can select the grouped brushes and make them a brush entity. It's sort of a hidden feature. In this mode you can then double click the brush entity to select the entire thing.

I don't use this often but give it a test drive. 

I have a room with non-orthogonal walls, and I'd like to make 16 map unit wide trims (see screenshot).

I'd like to duplicate-resize the highlighted wall section and drag it precisely by a length of 16 units. Would it be possible to have a distance indicator appear at the pointer when I start dragging the face?

According to the TB manual it should be possible for me to drag the face precisely by 16 units:

The distance is snapped to the current grid size, i.e., if you drag a face by 17.5 units along its normal, it will be moved by 16.0 units if the current grid size is 16. This is useful if you are resizing brushes which are part of a curve because their faces will line up after the drag.

In practice, however, I was unable to resize the face in the screenshot by 16 units, no matter how carefully I tried to drag. (I had made a reference by duplicating the nearby trim and rotating it and was never able to align the wall with it when resizing.) TB seemed to always prefer the other snapping method over the distance method. :'( Did I misinterpret the above quote from the manual or something? 

When I use the vertex tool and hover the pointer over a vertex, its coordinates are displayed. Could you make it possible to easily copy the coordinates (without having to resort to typing the coordinates manually to Notepad)?

Could you also have the coordinates display and be copiable when using the face and edge tools, too?

Being able to copy and paste coordinates would be useful for inputting the rotation origin in the rotate tool. 

Could it be made possible to define your own axes of rotation (see the illustration I sketched with Paint).

In the drop-down menu, where the user can choose the axis (x, y or z) about which to rotate the selected objects, an additional selection of "user defined" etc. could be added.

After having selected "user defined", more options would appear on the rotate tool (see illustration), with which the user can type in the two points that define the rotation axis. Alternatively the user can set the points by clicking on the map. (It would be nice if the center of rotation, too, could be set with the mouse, btw.) :) 

This release contains a few bug fixes. It also fixes a major memory leak and a few crash bugs.

Is there any way that we can add mapping for Quake without the need for wad files? Iterating textures while working on a map is a pain by having to use TexMex, there's no need for an outdated and unsupported piece of software to be required in the tool chain.
TB2 supports Q2 mapping and that doesn't use wads, why should Quake in 2018? 

Trenchbroom is one of the nicest pieces of software that I've ever had the pleasure of using. Thanks to SleepwalkR and other contributors for all of their work on it. 

I'm quite indecisive when it comes to choosing a texture and I like to preview a lot of different alternatives before making up my mind.

To better see what the texture choice looks like in a room, I always have to deselect the faces to get rid of the red hue the selection gives to the textures (and also the red face edges).

Then, when I'm done assessing the the texture choice, I have to press undo a couple of times until the faces are selected again, so I can select another texture. It's kind of a pain.

I would really appreciate making it possible to toggle the red hue and edge lines on/off, so previewing texturing would become a breeze.

Thanks for all the hard work you've put on the editor. I might not be mapping for Quake if it wasn't for your editor. :) 

You should file an issue for this on GitHub. 

After you type a value in a key-value pair box and hit Enter, can you please please please make it so hitting enter escapes the mouse / focus from that box??

Every single time I do this, I then hit something on the keyboard to move the camera or whatever, and overtype my light value with S or my mangle with D or whatever. I don't think the mouse focus should automatically go back to the editor view, just out of the damn textbox so when I hit a key, nothing happens rather than b0rking my text entry...

Thanks!! 

The property editor is optimized for quick entry of multiple key values. It is also impossible to separate mouse focus from keyboard focus with wxWidgets. Sorry, but I‘m afraid you‘ll have to get used to clicking the mouse in the 3D viewport. 

I'm used to mangle = sd , it will be a staple of any of my future mapping ;) 

Contains plenty of bugfixes. Available on github as usual: https://github.com/kduske/TrenchBroom/releases/tag/v2.0.4 

TrenchBroom 2.0.5 is functionally equivalent to 2.0.4, but was necessary to fix the macOS build scripts: https://github.com/kduske/TrenchBroom/releases/tag/v2.0.5 

Get it as per usual: https://github.com/kduske/TrenchBroom/releases/tag/v2.0.6 

Even though I don't actively use TB, I still install every new version. Much appreciated how you continue to work on and improve the editor and to see what people create with it. 

Thanks must also be directed at ericwa, who not only contributes features and fixes, but also carefully checks my code (and catches lots of problems). His contributions, and feedback from the community, are very motivating. 

I've always called him Quake's MVP! 

with a finger in every pie. 

Thanks sleep and eric. Some good fixes in this release - especially happy about the move brushes to world change. 

Trenchbroom is a really nice editor and makes soo many things about a billion times easier than they were in Worldcraft (as amazing as WC was in 1997, it barely runs any more).

Thanks especially for fixing that quirk of moving brushes to worldspawn. I also wish there was a way to disable selection of worldspawn when double clicking on a regular brush, since I never actually want to select it, but frequently do select it by accident.

I'll probably submit a bunch of suggestions to your github after I've spent enough time using the editor. 

Looking forward to your ideas (and your new maps)! 

Please finish that one dmrmx map - or you know, do whatever 

for this amazing piece of software!
It is no wonder that it set a milestone for Quake mapping.
