When inserting a node into a route the newly created segments should try and maintain (copy maybe) the original segment’s constraints and dimensions. We only need to dimension the position of the newly inserted node in regard to existing geometry. Fully constrained sketches go crazy when inserting a single node, removing existing constraints and deleting dimensions in the process as well.
