    Groin Vault with Adaptive Points

    I'm trying to make a simple groin vault family using adaptive points. The goal is to place each point at the room corners once in the project and then control the crown height using a parameter. easy, right?

    I got this concept to work by just using just points and splines but I can't create any forms, i'm new to adaptive families so forgive me if this is an obvious answer.

    If I could 'split' the splines where they overlap with the crown I think that would work but I can't figure out how. I've attached the family, any help would be greatly appreciated. thanks!

    for anyone interested. All I had to do was make a 7 point surface to nest into my vault skeleton family and attach it to my rig. The trick is to use the 'divide path' tool and create points along the splines to snap to.

    not bad!

    Very sweet!!! I used to make these with intersecting voids to cut solids. But this is a great idea.

    thanks man! right, I did see a great tutorial by Paul Aubin how to make a groin vault using roof extrusions, but we are doing many vaults in different sized rooms and can really benefit from something that stretches.

    here is Paul's video

    Overall i'm happy with the adaptive component approach, I may want to make a 9 point surface rather than a 7 point to smooth out the spline joint, but its fine at a low radius.

    here's the final family with some thickness

    Looked like fun, so...

    Here is my 2cents.
    I did a 4point generic model adaptive family with arcs that were used to create the surfaces and 2 voids to cut them in the middle. An offset of the midpoint was used to avoid the error that arises when the 2 meet at exactly the same point at the top.

    I made the orientation of the points allways vertical, but this could be changed. Anyway...

    These are great! How did you go about hosting the 4 points to the floor, and in what type of view?

    I'm finding placing these points and keeping the edges of the from orthogonal very temperamental. Any ideas how I can keep my family to have right angles and move with the floor?

    thanks

    The trick is to host points to edges of the floor, and then change the normalized curve par

    thanks for the quick reply!

    I'm facing a strange issue where Revit doesn't allow me to place more than one instance of an adaptive component. For example when I first load the vault family into the project and place the four points it works no problem, however when I try to place a second vault with different dimensions I receive an error. I have noticed that I am able to repeat the first instance using the same parameters , but when I try a vault of a different length or width, it breaks.
