Not sure if this is possibly included in the INVGEN-3643 scope, but it'd make it a lot easier to focus in on a parameter by name if the DrawingEvents included OnParameterChange that you could listen to. Especially if you're in an iLogic rule that's triggered on any parameter change, instead of either writing out it's "before" and "after" values that have been changed by another rule, to a text file using System.IO or (providing you don't have anything triggered off a property change) writing it's before value to an iProperty and then doing the before/after comparison. The "OnRetrieveDimensions" is still the only event on this object I see in Inventor 2026 as well, so it'd be nice to expand it a bit.
