Rotate multiple shapes, can't find error

[Ernst_van_der_Vecht]

I’m making a script that puts wooden facade cladding of different sizes (rectangles) on curves. So I duplicated the different rectangles, calculated where the begin and endpoints of the rectangles are on the curve, moved the rectangles there.

With pipe variable I tested the clockwise direction, start- and endpoints. All seem ok.

Here is what it should look like.

The rotation works most of the time, it seems alright on non-vertical and non-horizontal shapes. I have tried two methods to make ik work in alle cases, but no luck.

I’ve attached the script with internalised input. Any advise?

I’d use the orient component to move the rectangles from the origin to their locations on the large rectangle.

The plane Z axis goes upwards on all planes.

Works, thanks! Here’s a view of what it means to the whole script:

Solved for the use of this project. Yet, I would like to know why the rotate method didn’t work. If anyone knows, it would help others too.

If you provide a plane and calculate the angle between the x vector and the vector you created, the angle is correct.

The 2D angle is calculated counter clockwise from the x axis.

Furthermore if you would rotate first on the XY plane and then move, you don’t need to provide a plane for the rotations…

Thanks. I see the need for the plane has been discussed elsewhere too. For others: some insight in the necessity of the plane can be found here:

Problem with angles

Vector Angle

Is there anyway to force the Vector Compute Angle component to calculate angles in certain direction, like always clockwise. As it looks like it’s computing the smallest angle between vectors. Vector Angle.gh (10.6 KB) [Vector%20Angle]
