Braceworks does work, it has been extensively tested and functions as designed.
There are some limitations, such as no ground support calculations (we currently have no way to perform wind loading calculations for outdoor structures) and certain specialized scenarios where you must have a structural engineer perform the calculations.
The issue here is that the Bridle tool and hoist tool have to follow the recommended manufacturer usage guidelines. If Spotlight does not follow these guidelines then any structural engineer who works with the calculation results will automatically fail them!
This means that currently hoists and dead-hangs will not connect automatically to a rigging point in the same way as a regular bridle. Current best practice for hoists and dead-hangs is to use the house rigging points as an insertion guide, you need to make sure your truss center line is centered on the point or points (snap to object works great for this) and then use the points as guides for where to insert the hoist or dead-hang (setting the high hook height or dead-hang trim height appropriately in the insertion tool preferences). Although they do not directly interact with the point, when you run a Braceworks calculation both will automatically generate a rigging point which will document all the forces acting on it, which will replace the unused original point.
This reflects reality, if your truss is not directly below a rigging point the truss will be pulled out of position, as it naturally balances between the points, which in turn will drastically change the forces acting on the rigging points!
And yes I know that in reality if the truss is not directly below the rigging points most onsite riggers will just move the truss into the correct position, because this is what I used to do (if there wasn't a good reason not to) when I still did rigging work.
Moving forwards we are going to improve this by making it possible for hoists and dead-hangs to connect with hanging points in the same way as other bridle types. However, this is not as simple as it sounds. If we just allow them to connect when they are not perfectly aligned then it not follow the manufacturers recommended usage guidelines and potentially move the truss out of position, both of which will invalidate the Braceworks calculation. This means there will have to be some specialized options for what happens when the truss and points are not aligned such as automatically moving the truss to correctly line up with the points (not always possible, if its a complex rigging system) or maybe automatically inserting per-rig, are 2 of the possible solutions.
