I am trying to come up with convincing reasons why there are no as built joints in direct modeling mode.
At the moment I am a bit flabbergasted!
No as-built joints in direct modeling mode ?
Accepted solution
I can provide that. As-Built Joints require much simpler selections than "normal" joints. Just pick two components, and, for other than rigid joints, other geometry to define the motion of the joint. Whereas a "normal" joint requires you to select geometry that defines a joint origin on each component. Normal joints have enough information, then to define a coordinate system on each component, then relate those CSs to each other with a joint. However, for as-built joints, we don't capture that information in the selection - we infer that both components' CS are therefore defined by that one geometry pick (or in the case of rigid, we just pick the component origin, I think). Anyway, for that system to work, it relies on those components being in a predictable position at the time the as-built joint computes. Without that guarantee, the joint would be meaningless, or rather would behave unexpectedly when a component is moved.
I guess that is a very long-winded way to say: As-built joints require the joint to compute to determine the components' position in relation to the joint CS, and since Direct models don't compute component geometry, we cannot assure that.

In this case it would be nice if the rigid joint, which allows to have an offset since a while would be able to record the current location of the 2 components as an offset.
Simple and effective solution!
