I know about datums, although I don't see much what they have to offer much here, I have never heard of shapebinders... it still remains a mystery to me exactly how you would model such a thing, especially in a reasonably efficient way.
for example, with the table yorik uses in his tutuorial https://legacy.gitbook.com/book/yorikva ... al/details
in a workflow similar to fusion I would make one of the legs to spec, by sketching the cross section of the leg, extruding it, then making sketches for the holes and using the cut tool, then make the table top, then simply copy and place the remaining legs into position on the table. Or maybe place the reference plane knowing what size I wanted the table to be, then mirror the leg once to produce an extra leg, then mirror both those at once to produce the other two legs, and draw the table top in a a way that references the positions of the legs. boom, quite fast to do.
This thing with making rectangular prisms (they are not cubes...) and subtracting them from each other by tediously calculating the correct positions is not practical for more complex things. It may work by a hair's breadth when you are just drafting i.e. creating a 3d solid from 2d drawings that already have all your dimensions. But to actually design like that is.... not practical at all, because it is too impractical to change anything or test etc. I also noticed that the holes are not in sensible locations in yorik's stuff. Similarly, the lego bock when made according to his instructions would not actually work, the features on the bottom part don't actually line up with the pegs on the top. if you tried to 3d print out the brick and stack them like real lego they would not fit together at all. The features are not positioned in the right places.
I don't suppose these guys that managed to get along ok made any videos showing exactly how? I think that is the only way to clarify this mystery...
