So was that you in the video @blanchsb , haha
Perfect, I would presume the empties could be parented to the part it is attached to.
3 Align with the Chassis on the other end.
the changes from @adrian2301 for the chassis.
I have worked hard on trying to work with everyone’s parts to get the chassis to a point now where I don’t anticipate having to make any more changes to the chassis, apart from maybe detailing, but the position of the key points such as where the loader arm attaches the chassis, I’m confident won’t change.
I’m still a bit confused on the part you talk about stretching.
I’ve borrowed your image, I’ll give it back I promise,
Ok Consider Piston 1 is your example in the video, point 1 is attached to the chassis and location is fixed but rotation is free. Also point 2 has a fixed location in relation to the main arm. So if the empties in your example video were to be parented to the chassis and arm respectively, when lifting the main arm, which is fixed at point 10 to the chassis, piston 1 would extend and rotate at point 1 and 2, perfect so far in you video. Piston 2 has fixed LOC at Point 5 and 6 in respect to part 2 and 3. Piston 2 when extended pushes part 3 which then rotates the bucket at the pivot point 8. Part 4 is there to stop it just flopping around.Part 1 and 2 are there to stop piston 2 moving in the wrong direction. So imagine the main arm raising up at the bucket end and pivoted at point 10, Part 1,2,3 and 4 will all move as they are all connected. All the pivot points from 1 to 11 will be rotating at different degrees and directions, while the main arm is raising but will always be constrained on the location to the respective part. Point 1 to the chassis, Point 2 to the main arm etc. etc. Where the piston is free to extend as in your example video, the only consideration going forward would be a limit to how far it extends and retracts. This I would suggest be controlled by limiting the rotation of point 10 for piston 1 and point 8 for piston 2. I’m going to stop there as I’m beginning to confuse myself.
But I’m not sure where stretching will be necessary.
