Hello everyone,
I have an issue trying to make this script work. Curve.PointAtParameter didn’t work and I don’t know why?
ca anybody help me find out. I appreciate it.

Your output of the List.Flatten node is all solids, those need to be interpreted into curves (group / list of lines / points) that make sense for the fitting. It might be the perimeter of one side or at the middle.
thanks for the reply. which node can interpret solids to curves?
Use GetLocation instead of Element.Geometry.
Sorry, you would only use GetLocation for your Duct. You still want the full geometry solids from your walls.
Your image is illegible. Zoom in so we can see your nodes.
You flipped your MEPCurve list and ListOfPoints list on the MEPFitting node.
You might also need to use list levels with the MEPFitting node if it’s expecting a list of points for each curve.
Looks like list levels is the wrong direction. You need to convert your list of points to sublists of points. Each duct should have its own sublist of points. Try List.Chop.
I did try sub-listing the points, and unfortunately, still didn’t work. I think MEPFitting.ByPointAndCurve works by list of points which represents the midpoints of duct and walls intersections and ducts are already represented by MEPCurve from ducts themselves.
thanks,
maybe you need to select the duct elements that intersect and make those the list for MEPCurve input?
I got it to work in a test file. What happens when you use List.Chop to chop your list of points into individual sublists?
what i meant was take the indices with values (other than empty list) from geom intersect, get those duct elements (get item at index) that intersect and feed those into the MERCurves input. just a thought, don’t have time to test or figure out process.
when the list is flattened, there will be no empty elements in it. I think there is no need for Get Item At Index
