you can find all the info of the hypotenuse (green) in a variety of ways .. (for instance, a^2 + b^2 = c^2 to get its length.. you'll know a & b in this case… then trig for the angles)
that hypotenuse is also the the hypotenuse of the un-trimmed board (red).. so you know the board width and the length of its hypotenuse which means you can get all other angles and lengths..
I was suspecting something like that - but my trigonometry knowledge was all too poor that I dared place bets on it.

for whatever reason, i still think there might be a way to do it in sketchup itself.. maybe jean L can come up with something
I also wonder this - but I also fear it might - due to lack of true arcs.
Where is Simon Le Bon btw..? -

SOH CAH TOA
that's one of the things that seemed to stick with me after leaving school..
Sine = Opposite/Hypotenuse
Cosine = Adjacent/Hypotenuse
Tangent = Opposite/Adjacent -
That stuck with me, too. I can't remember who I took to prom, though.

Tangent = Opposite/AdjacentTrouble is that I don't even remember what to use of this. I'm really annoying - I always have to look up this stuff, reading for a while, whenever I need to do such work with my plugins. ...which, when you place plugins for 3D software... ...I really should be knowing this...

Well, I figured out some of the accuracy issue on my last approach -- a bit of user error on my part since I was rotating the guidepoint to the wrong place and also the accuracy setting of the rotate tool was not set high enough... actually this still isn't exactly accurate (rotated to 45.6085) but it's pretty close now.
Try with the posts further apart - then you'll catch accuracy issue much easier. When it's close to 45 degrees it's harder to spot.

@Jeff - I checked every aspect of interacting with a DC, it shows nothing for me.
Edit -- Gotcha, you have to actually open the model instead of bringing it in as a component.
Best,
Jason. -

oh man.. that reminds me of some problem with sharing dynamic components.. are you directly opening the file i posted or are you bringing it in to an existing model?
you have to just open the file i posted then the options should be available..
(or something like that..
i remember having problems with bringing in DCs from the warehouse into existing models and none of the options were available.) -

ha.. i always figured you ruby gurus were math wizards..
nice to know you're sitting around looking things up on a per case basis like the rest of us

You really don't need to muddle around with math too much when making plugins for SketchUp. Their API is doing lots of the heavy work. I don't even fully understand the transformation matrix - though reading up on that now.

I do that for everything I do - always. Simply because I like to know I'm doing stuff correct and efficient.
-
This method still works as expected no matter the distance -- the problem is just that the rotate tool is not precise enough to put the guidepoint exactly where it should be.
@Jeff -- yeah, sorry my habit is to bring them into a model via the component browser, so it was my fault.
Best,
Jason. -

I 've found a tricky way.
really? sweet!
I'm on a phone now so I can't see it but the suspense is killing mecan anyone verify?
-
Wow, that is tricky... I never would have approached it that way.
What gave you the answer?
Best,
Jason. -
Nice one! works for me!
-
I dont even know, just an intuition.
So do I won something?

I was hoping gilles nailed it -

What's missing? I redid it from scratch. I would suggest drawing a guide-line inferenced perpendicular to the new diagonal lines. (I group the newly drawn diagonals so I can rotate exactly to the perpendicular.)
