Generate point on surface

[bhall]

Hi Guys,

I am trying to automatically add rooms in a model which only contains out of generic models (rooms).
I allready managed to find the bottom faces of the generic models, and translate the perimiter to room separation lines. Now I want to automatically add rooms within the room separation lines using the ‘Room.ByLocation’ node.

However, when I find the center points of the rooms, some centerpoints fall outside of the room boundary (see picture). Is there a way to generate a point on each surface (does not neccicarily have to be the exact mid point), which always falls within the boundary?

Thanks in advance!

@bhall ,

you mean like this?

I am now trying with a test model of 3 rooms. later i will do it for a model of 1000’s of rooms.
some rooms are shaped like a ‘U’, so i want to generate 1 point for every surface using 1 piece of script that will not create points outside of the room boundary.

@bhall ,

this way, you will struggle with Null-rooms…

Hi @bhall,

I already solved this problem of U shape of rooms.
You can use the Element Inner Centroid or Surface Inner Centroid nodes of the Genius Loci package.

Visual Center for Rooms

Hi Amadeu, Indeed, the centroids can be outside the polygon: [element centroids OOTB] But the Polylabel algorithm can be used with Revit : [inner centroids] [inner centroids 3] And it’s a good way to tag items : [inner centroids tag]

You can also utilize an isocurve, intersect that with the surface, gather the first resulting curve, and pull a point at parameter 0.5.
