Mini-challenge

All that mathematical notation is greek to me, but here's what we know:
- we know the diagonal length and position (call it a hypotenuse if you want but it's really a diagonal to me).
- we know the desired width of the beam.
- we know that the angle should be 90 degrees on the opposite corners from the diagonal.
As far as I can see with that information we should have no trouble drawing the thing directly using nothing but the line tool and a few guides... because the actual numbers (aside from what we already know) should completely irrelevant.
Here's a video -- it works, and consistently (not to mention dirt simple)... it's just that SketchUp seems to have lower than perfect tolerances for the 90 degree guides.

Hi
May be like this?
Moujiik
im curious to see what you've come up with. I'll be able to download your file in an hour or so.
-
I'm not sure why you think so -- all 4 corners are 90 degrees, and since we know where 2 of the corner are why not use them...
It works fine and you get about as accurate results as any other non-plugin solution put out here.

Jason.nah.. the corners won't end up square when doing that
-
OK... did you watch the video? Those results are as accurate as any other non-plugin result I've seen in this thread -- it works, you can say it shouldn't if you want to but it does.
I guess the thing here is I don't think square corners matter anyway, since they will be trimmed off -- what matters is the width... I mean after all this is a cross brace.

Jason. -
you're right.
And it's the same solution as Tig's.
I miss my real wood planks. It is so easy to do that for real!moujiik
-
yep. watched it.
the corners need to be perfectly square if thats where you're drawing a line to determine the boards width.
upon finishing your method, delete the diagonal (as to avoid confusion) then measure the angles of the board's corners. they won't be 90°

sometimes.. I'll upload a picture a little later which shows a situation where you can't just put a long board in there and trace/cut it.
another reason for having a precut board is that you can use it to plumb a wall with. (instead of needing two people do it -- one to use the level and one to trace the board)
-
Yeah, I already said that several posts back -- but it is consistently the same regardless of the distance between the beams, which is why I said I think there may be an accuracy issue with the engine somewhere.
If the method was faulty there would random results each time... right?

Jason.in this particular case, the fault isn't sketchups. the approach is geometrically flawed.
edit-- for instance, doing what you're doing.. the wider you decide to make your board, the further away from 90° you'll get in the corners.
-
Gotcha, yeah, I see that now -- so it was just an illusion created by the long rectangles/aspect ratio of the beams here.
I guess nothing is as simple as it seems with math (which is why I avoid it as much as possible).
I'm ready to just use Fredos tool and call it a day

Jason.me too. fredo solved it..
I'm still curious to see an alternative solution but as far as actually drawing the thing, the fastest method will win and I think it's going to be fredoScale's latest addition. -
Jason,
You're right.
The native Rotate tool seems to find inference in alignment of edges with others. You have to play around with it, but it seems to find it in the end.

Yeah I was trying for stupid simplicity, and just ended up with stupid
BTW I'm playing with the protractor a bit more and it seems to be snapping to something, I can't tell what -- and it's not giving me any feedback, but the result is the missing correct 90 degree reference... maybe they (SketchUp Devs) already solved this problem and we just never found it.
It's strange though because you have to kind-of slide the protractor along a guideline until it just decides to snap for some reason.

Fredo
what the heck ??
at first i though 'this guy is nuts' but then after fiddling around for a minute or so, it eventually snapped exactly into place ???
so i guess the quest now is figuring out what it's doing and how to gain better control over it..
-
haha.. this is crazy..
what's going on here? i don't understand..
(i mean, the reference click of the rotate tool doesn't even happen on the edge of the board that needs aligned.. like in fredo's latest video.. i'll click on the bottom of the board then the top of it snaps perfectly into place.. and i've been able to repeat it a few times now..)
-
That's crazy -- I'm sure the Dev Team was really laughing at us for the last 13 pages, with us flopping around trying to solve something they already took care of
Edit -- it seems to still be limited by the angle precision settings... much like my previous try using the guide-point. I think I'll still with your plugin solution.
Best,
Jason. -
Fredo is a devil, be afraid!
Bravo!!!

I was doing this earlier today and trying to zoom in to find the error. Never thought it was actually aligned as I was 100% certain it wasn't possible.
Not to mention spending 2 hrs with TOS plugin hoping to find the golden egg.

right.. it's weird. there's no feedback when it happens so it's hard to tell if you're just at a .001 angle or actually snapped into place. but so far, ive been able to get it perfectly into place in many situations (some situations (variations on height/length/boardwidth) I haven't been able to do it)
