I have been asking for this, so, I am sorry for the repeating.
Is there a Reference Manual for Dynamo nodes?
That is, a document that list all nodes by input and output data types?
We waste an inordinate amount of time trying to accomplish the simplest tasks because there is not a Reference Manual for Dynamo.
For example, to extract the normal of a plane there is the “Plane.Normal” node, which requires a “Autodesk.Designscript.Geometry.Plane” input.
Unfortunately, I have data in the form of “Autodesk.DesignScript.Geometry.Surface”, not “.plane”.
In fact, three is no “Element.Plane” node, but rather “Element.Faces”.
Because there is no place to look up all Dynamo nodes that output the “Autodesk.Designscript.Geometry.Plane” data type, I am basically stumped.
Maybe I should start a blog with a complete catalog of dynamo nodes data types… ??
