Let me click on a line while using GUIDED perspective transform

It's nice that I can click and drag a line to define my horizontals and verticals. It would be incredibly faster if LR would use some vision processing to find these lines for me. For example, I click on the edge of a building and LR would look at the region and find the line and apply the Guide. File this under my mantra: "Please make Lightroom SMART. Code it to assist me not just be a interface full of sliders."

That is in fact exactly what the other Transform Upright controls use (Auto, Level, Vertical, Full). These "smart vision" controls sometimes fail to properly correct the image due conflicting  or insufficient horizontal and vertical edge detail. When that happens you'll need to "manually" correct the image using the Guided Upright tool with your "smarter vision."

Kinda but not really. This other methods are doing a global search for strong lines. They don’t work at all. I want something in between full manual line drawing and AUTO where I can click on the line I want LR to use. And/or: LR does Auto/full/etc but throws down the lines it’s using so I can modify them.

I think Todd still has a point. In images where your proposed ‘auto guided upright’ would work well, the current auto upright tools probably also work well. And in images where the current auto upright tools don’t work well, a ‘guided auto upright’ or ‘auto guided upright’ might also disappoint very often.

You would need to align and define at least two parallel edge-areas, which isn't any faster than the current Guided Upright tool. I agree there is room for improvement in the current Upright tools, which often fail for no apparent reason as shown in the example below.

Actually, this is probably an example where the proposed tool would be an improvement. It's indeed very strange that the auto upright tool fails with this image, because the lines seem to be clear enough. If you could simply click on both sides of the shed to set the two guide lines for Guided Upright, then that would be a lot faster than placing both guides manually.

Exactly. To true up an image with all four guides takes about 15 seconds. Four clicks near an edge would take 2. 13 seconds per image, 5000 images per year is a savings of 18 hours. It would be a large improvement if there was simply an addition of “snap to edge” option.

Yes, but like I said earlier, this is the odd one. Normally an image like this could be corrected with one single click on Auto Upright button. That is even faster. And images that fail in Auto Upright would often also fail in some ‘Auto Snap to Edges’ guided version, for the simple reason that the same technology would be used to detect the edge that you clicked on. So your math is probably far too optimistic.

Meh. I can say with absolute certainty that the Auto modes have been 0% successful. I shoot architrcture. Almost correct doesn’t fly.

You keep missing my point. If auto detect of the lines fails all the time (as you claim), then auto detect a line after you pointed out that line will also fail. The algorithms apparently aren’t good enough.
