Part 4 of a 5-part series on working with 3D scans in Autodesk Fusion.
This is the one where it moves. Josiah Fallaise finishes building reference bodies for the tie rod, knuckle and coilover, then joints the whole suspension together: ball joints at every control arm, a steering rack on a slider joint with 80mm of travel each way, and a tie rod connecting the two. By the end the assembly articulates and steers, all of it built from a single scan of an assembled car.
The most useful rule in the video is at 19:32. When you create a joint, the second object you select is where the pivot point stays. Pick them in the wrong order and the arm pivots from the knuckle instead of from its own bushing, which quietly ruins your geometry.
He also does not hide the rough edges. Some areas of the scan had almost no usable data, and around 10:44 he draws a best-fit cylinder by eye and says outright he could be several millimetres off. His advice throughout is to scan components individually whenever you can, and he shows what the better data looks like so you can see the difference.
The closing thought is worth the watch on its own. All of the work goes into the prep, the same way it does with paint. The scan quality determines how easy everything downstream will be.
One last detail at 26:53: the ball joint on one control arm sits slightly off. That is not a modelling error. The arm came from a wrecking yard and it is physically bent, which the scan picked up.
Parts 1 through 3 cover orienting the scan to the origin, separating the first component, and breaking the rest of the scan into individual parts.
