Extract boundary from roof - create ceiling using the boundary

[M4RC1NE8]

Hi All,

I am writing a graph that should extract a bouindary from a roof and use it to create a ceiling replacement.

Why? Cause one of the famous architectural practices decide to use Roof category to create ceiling which make everything far more difficult for me, hence the query.

So far I canot find any node that would help me to extract the boundary/perimeter/outline form a Roof but I create a ceiling using a node Ceiling.ByOutlineTypeAndLevel I used before to create ceilings automatically within a set of rooms - it is this diabolical Roof I cant crack.

Any advise very welcome.

How to get the sketch lines of the roof

[Безымянный] [Capture] Thank you! With node Springs.Collector. Element Sketch is a little familiar, tried to illustrate. The roof is given, in the dynamo I select all the roof elements through the category, we get the FootPrintRoof using Springs.Collector. Element Sketch (as an option) we get such roof lines similar to the sketch, but they do not have the parameters, as in the sketch lines of the roof, if you choose them, in the mode of editing the roof. I would like to know if it’s really p…

Rhythm have a node Roofs.Footprint node that can do the trick.
Simple graph below that creates a ceiling from the roof outline and sets the height

Check that you have the right Ceiling.ByOutlineTypeAndLevel node. The first input port will be named ‘outlineCurves’. Note the list levels on the node updating the ceiling levels

Brilliant - thank you so much fellas!
Weirdly the graph works in Dynamo but in Dynamo Player it loses its selection once the graph starts.

Here is the graph in case you would like to fiddle with it - surely I’

ve made a mistake there just can’t pin point it.
