I will do my best to describe
This is for a woodworking project. I am building a desk and the legs are shaped like a Z. I know the top and bottom leg dimensions and the diagonal is a 4x4 post just like the top and bottom legs are. The overall dimension of the piece is 30 inches.
Since I don’t know enough data points to calculate this mathematically I am trying to use Sketch up to Mock it up for a “close enough” calculation.
To try and calculate this in sketch up I put in the pieces where they go and drew a 4"x36" rectangle with the corner intersecting where it should go and use that as the rotation point.
below is a sketch of what I am trying to figure out and also a video of me getting close in sketchup. I need the bottom edge of the rectangle that I am rotating to snap to the bottom corner of the top rectangle.
