LinearDimensions are always aligned with the world or cplane axes. You need to make your dimension aligned.

This means setting the Aligned property to true, specifying the correct plane and remapping the 3d points into plane space. I've made a start, but I can't figure out why the dimension goes in the wrong direction. But hopefully it'll get you on your way.

ps. the (1), (2), and (3) dots are just there for debugging, I wanted to see how they mapped coordinates work.

Just to make sure.. you know you can create dimensions directly with GH components right? They will bake correctly.

    thank your very much for your detail answer,I read your code, but found they still doesn't work as I want.from your picture,the dimension seems reverse,and I changed the plane to get the the dimension,but still not work,It's so wired!(the pt3 seems valueless).

   But still thank your for your detail answer.
