Thanks. I haven’t heard of Mapathoner, I’ll have to look into it. 
And I do have Building Tools installed, but I found some of those methods not quite living up to the reality (like the “parallel” stuff).
Perhaps it would work in a grid-like city or development, where all the houses/apartments are looking the same and on a perfectly straight street…
But from the 130k+ buildings I’ve added within the past year:
- The buildings are at all sorts of weird angles/rotations.
- Look at those trailers around the cul-de-sac/"turning circle"s!
- = Can’t easily “parallel”.
- Each house has some unique touches.
- Not same shape.
- And not perfectly square/rectangular.
- = Can’t easily copy/paste.
- Some houses are very close to sidewalk, some a little further back, and some SUPER far back.
So you try to “mass highlight”/“line these things up” or come up with some average, so your mouse doesn’t have to move quite so much.
Or, you could just:
- Push OK
- Get 90%+ of the way there.
and THEN do all your little minor dragging/adjustments if needed.
You can even use all your helpful Building Tools tricks on top of that, but shaving off all those initial 2/3 clicks to even draw/rotate the shape in the first place.
You can then focus on refining more of the fine details—like an awning jutting out or extra garage attached to the house… or not-quite-rectangle, not-quite-triangle commercial buildings:
or adding all those crazy little nubs on big factories/apartments:
or this super weird seashell-looking house:
I’d say the AI did a pretty fantastic job on those last 2, and all I had to do was “push 1 button” and drag it into place!
(Imagine trying to draw that huge senior citizen complex manually… it would take you weeks, months, years!!!
