Retrive mesh of area element

[Anonymous]

I'm trying to triangulate an area element and then turn it into an svg object.
It's possible? Does anyone know a method to do it?

Thank you.

Sorry for my English.

First of all, explore the area element and its geometry using RevitLookup and see what you can find.

I would probably start by retrieving its boundary segments and use those to construct the SVG:

By the way, my RoomEditorApp retrieves and exports room surfaces to SVG, so that might be of interest as well:

Thanks Jeremy,

sorry if I answer you only now but I have been busy in other jobs.
I have found your suggestions very useful with which they are able to recover the vertices of the area, but now we have decided to abandon SVG for a WebGL viewer that requires the triangulation of the area. Do you know if there is a method in the API? Can you give me an example?

Cheers

Every single geometrical object provided by the Revit API can be easily triangulated using the Triangulate method:

Analogously, curves provide a Tessellate method:
