Surface methods and properties (API)

[m.shcheblykin]

Hello dear experts,
By accident I bumped onto a fact that surfaces in dynamo are like classes in revit API. It seems that they have a lot of hidden properties and methods which you can not access with a dynamo user interface.
For instance I found that a surface object contain an attribute that is called Faces. Faces have an attribute Loops and these loops have a method that defines if a loop is external or internal

Therefore, I understood that somewhere should be information about Dynamo/Autodesk geometry like we have a website for Revit API.
In another words, can you please advise where I can get all the info about the dynamo’s geometry API

Hi

you can check the XML documentation from nuget

https://nuget.info/packages/DynamoVisualProgramming.ZeroTouchLibrary/3.1.0-beta4184

or use fuget, but the service seem broken

https://www.fuget.org/packages/DynamoVisualProgramming.ZeroTouchLibrary/3.1.0-beta4184

or you can use some software to read the contents of DLLs (like VS2022)

Some of these were intentionally hidden as new properties and methods are added to Dynamo in a way to keep them from being exposed in the library. The reasoning for this varies - performance degradation, user confusion, forward compatibility of existing files, and more.

I do recommend looking into these classes, but try to limit passing their outputs directly into the Dynamo environment when not needed (for the above performance concern).
