List of entities and organisation ?

[Iltis]

Hello,

Do you know if there is a schematic/list of the SketchUp geometrical entities and of their relationships?

For example : ArcCurve (arcs and circles) is a subclass of the Curve class, and an edge is a part of a random curve if edge.curve return a curve, and a part of an arccurve if edge.curve return an arccurve.

Best regards,
Renaud.

The new docs (work in process) will make the class hierarchy clearer: http://ruby.sketchup.com/

And this diagram is a bit out of date. (There are some missing classes, and perhaps changes since it was drawn back in the v7 and v8 days.)

Implies an incorrect assumption.

The SKP document object hierarchy (ie, the model database tree) is a wholly separate construct than the Ruby class hierarchy and relationships.

For example, the Sketchup::Edge class is not a sub-class of the Sketchup::Curve class. Both, are descendants of the Sketchup::Entity class. Sketchup::Curve and Sketchup::ArcCurve objects are special collection classes that connect edges together, but are not themselves an actual "model element". Sketchup::Edge objects are an actual model element, and so are a sub-class of Sketchup::Drawingelement.
