Hi @alex_volt

Currently your feeding “String” to “IsSolid” you need to connect “Boolean” node or use code block “true”.

You’re feeding the node Revit model curves. That can only work inside a family as the message says.
You need to connect Element.Curves directly to Form.ByLofstCrossection.Additionaly you can try making Polycurves from the curves before that.

It does not work yet
Thanks for collaboration
I saw this

Form.ByLoftCrossSections

but here it works … but I do not think there is a difference

[viktor_kuzev]

Are you running the definition from a project or from a family?

[alex_volt]

In the project I entered the family formed by arcs and lines

[viktor_kuzev]

So the example you showed me is running in a family. Form.ByLoftCrossSection works only in the mass/adaptive family environment.
