Verification about splines

christopher.pepin — Mon, 30 Jan 2023 21:57:08 GMT

I just want to see if I understand the limitations of Revit correctly. It seems like there is simply no ability to apply constraints to spline control points. I have found no way to do this in LT. Is this possible in full Revit at all or is this simply not possible in any version of Revit?

With full Revit you can create a mass or adaptive family and constrain its points and use those points to generate spline.

To be clear I am not talking about just constraining the endpoints but the control points of the bezier curve. The points that the spline does not actually travel through but define how tightly the curve bends.

No.

By the way, the method I said earlier doesn't involve control points. If you want a tighter spline just add more points by and control their location.

You can certainly Snap them to intersections, but not lock 'em. But you know you have to handles at the end points; don't you? Open circle and solid dot. Two different functions. TAB-Select to grab the right one.

@ToanDN That is extremely frustrating. It seems absurd that they won't let you define the points that actually describe a specific curve.
