Is there an easier way to weld or do other joints. I find it extremely tedious playing solo a bunch of times just to get the C1 and C0 properties. Is there a way you can edit it while in play solo mode and then write down the values once you get them? I've also seen with welding there is a way of making a weld while keeping the brick in its original rotation and position to the parent part, such as the Handle in a tool. If anyone has any advice that would be extremely helpful!
If you want to weld two parts together such that they retain their current relative orientations, do math:
weld.C0=a.CFrame:inverse()*b.CFrame weld.Part0=a weld.Part1=b
