Trenchbroom: Show length of modified edges when they aren't axis-aligned

[jmickle66666666]

When moving a face, or changing a vertex, it would be incredibly useful to know the lengths of the edges you are affecting. It is currently difficult to work with unorthogonal geometry in Trenchbroom because the only lengths shown are the bounding box of the brush, which is not useful information once the brush is rotated.

Here is a proposed implementation: when moving any vertices (in this case moving the entire clipping plane), any edges connected to those vertices show their length (in a different color to distinguish from the bounding box length) at their midpoint. Edges obscured by a face still show their length, but in a darker color.

I understand that having exact measurements is sometimes useful, but this seems like a lot of visual noise. I‘ll haven’t think about it, maybe there‘s another way that is less cluttered.

Show edge length when a mouse is over an edge?

[kduske]

I think he wants to see it during the drag, which sounds reasonable enough. I mean, you want to know during the operation whether or not you have reached the desired length.

what jazz showed is how doom builder works and it's something i badly badly miss from making doom maps

this is by far the biggest feature missing in trenchbroom for me and it's seriously hurting my ability to map

[anotak]

i still think about this every time i open trenchbroom

In the age of crazy extrusion-based layouts and _trim culture_, this is needed now more than ever!
The Doom Builder implementation is swell. Possibly make it only show when you're highlighting a face, or currently extruding? As those are the only times I could see something like this being useful. It's also good for texture alignment and other things of the sort, keeping all 3/4th values in my head when mapping gets tiresome when other more primitive editors show information like this freely.
