I want to combine several connected lines into a single line

Looking at the node, it shows 5 polycurves, but I don’t think this is actually a single line.

I want to place a single family along the line path. For example, like a pline in CAD.

Your five curves (Line, Arc, Line, Arc, Line) are added to one Polycurve with those five curves as “subelements”.

If it were 5 Polycurves, it would read like this:

PolyCurve(NumberOfCurves = x)
PolyCurve(NumberOfCurves = x)
PolyCurve(NumberOfCurves = x)
PolyCurve(NumberOfCurves = x)
PolyCurve(NumberOfCurves = x)

So this really is just one line (with five segments).

I want to prevent multiple families from being placed.

Revit cannot define a PolyCurve so Dynamo cannot define a PolyCurve in Revit. You’ll need to approach the problem differently. The simple solution would be to place multiple family instances - one for each curve.

Thank you. I wanted to ask about whether this is possible rather than a solution.
