My truck ramp project

[gIobalRanger]

Hello there, I am making a ramp for my truck and I have a problem;

The ramp has 2 parts, each one has its own fold animation.

1 = Green part, it folds first and it can fold without affecting 2
2 = Red part, it folds after 1, 2 must be linked to it.

START:
1 Folds:

then 2 must fold to its angle but the problem is I can’t rotate number 2 with 1.

How can I weld the number 1 to 2?

Also here is some more info:

FG has motor in it, B is the pivot, B and FG are anchored, MAIN is not. (Main is the ramp parts)

Combine it to 1 animation…

They must fold separately and this must be the final image.
Number 1 must be connected to number 2 without affecting their movement.

OK, so weld it and tween it…

Man, I am asking how to do it but you are just saying.

Here is a helpful tutorial on how to tween models which includes how to tween parts on a hinge.

Introduction to Tweening Models

Note (06/30/2021): Due to the release of the new pivot APIs and the thankful deprecation of SetPrimaryPartCFrame, the legacy method of CFraming is now also appropriate and you do not necessarily need to use this welding method. Do note that the pivot CFrame is different from the PrimaryPart CFrame though, so you will have to account for that when writing your proxy objects.
