    SketchUp Challenge?

    Would any of our SketchUp users be up for a challenge? This should be a simple one for you.



    Two 48 in tall, 4 in. square posts with a 2x2 placed diagonally between them such that the pointy ends of the miters are exactly at the top and bottom of the posts. Nothing to it, right?

    The diagonal must measure exactly 2 inches square in cross section.

    I'm already stuck.
    The rotate tool is letting me down. I'm trying to rotate a 2x2 down into position, but it is working off of the WRONG side of the 2x2, so I can't get the point end lined up with the top of the 4x4.
    There's usually more than one way to do it...

    Art, have you considered drawing the diagonal piece in place?

    There's going to be a catch coming up, right?

    I did, but that seemed to me to need a whole bunch of math to figure out the correct cross section.

    I tried a different approach. I drew a long horizontal 2x2 precisely straddling the halfway point.
    Then I made marks to set the exact center, and I spun it in place.

    I think this is probably still wrong... I did get the ends to line up with the top/bottom of the post, but it seemed a bit by accident, as I did not see any way to force them to "snap" into place.

    (I did not continue the exercise to clean up the ends of the 2x2s. I figured that wasn't really the point, and I wanted to show how I did it.)

    Glenn, now what made you think that?

    You're right, though.

    Did you get it is something still off?

    Art, that's good thinking and you got pretty close but it still isn't quite right.

    Take a look at mine.

    yeah, nothing like zooming WAY in to find the small errors.

    I'll probably keep thinking about this long after my lunch break is done. bad Art. bad bad.
    But right now I'm not getting it.

    I want to approach this like a woodworker: just lay the 2x2 on top of the two posts and draw the line, then maybe transfer it to a miter saw to make the cuts. Done.
    To do that I want to draw a 2x2, select the rotate tool, and then select the face to pivot, and then select the face that is doing the lining up. Right now, SU only seems to let me do the first two. It makes me use the pivoting face as the one that is snapping to a point/line/face. grump grump grump.

    Art, think about something else for awhile and we'll get back to this. We'll see if anyone else chimes in.

    I think I got it; 3 components, 2 @ 4x4x48" and 1 @ 2x2x52-51/64".
