I have a c++ exporter that is working well. Now I would like to be able to update (or freshen) my export anytime the Sketchup model is changed (add/remove/modify types of actions). Is there a way to do this in C++, and if not, is there a right way to do it in Ruby, and have it trigger actions in my…

[image] mgraham: I would like to be able to update (or freshen) my export anytime the Sketchup model is changed (add/remove/modify types of actions). This is going to be an issue for users. They already complain when autosave kicks in on it’s set interval. I cannot see users being fond of ha…

That helped. As an associated question, I am calling SUModelGetEntities to get the entities to export, but it seems to only get the entities that were present at the last save. Is there a way to get the current entities? Edit: looks like I need to use SUApplicationGetActiveModel, but when I replace …

Of course the former is designed to load a SKP file into a SUModelRef object. (1) There is a linking difference in using the C API for files and the live application. Did you link to the correct libraries ? I think for working in standalone mode on files (a 3rd party app or command line utility)…

Apparently I had an older SDK. I downloaded a fresh copy, and it now compiles, thank you!

Great! I would suggest however that perhaps you leverage one of the live Ruby Sketchup::ModelObserver onSave callbacks rather than try to attach observer(s) to a multitude of geometry objects. Now that you have a valid reference to the live model object, you have an object to attach an observer obj…

Update: it compiles, but when it runs it throws an “unknown exception” error. try { SUModelRef liveModel_; SUSetInvalid(liveModel_); SU_CALL(SUApplicationGetActiveModel(&liveModel_)); } catch (const std::exception& e) { std::string foo = e.what(); } I am linking both the sketchup.lib and…

My exporter code is an expansion of the Quick Start “reading from a .skp file” code, and it works well. I have swapped the line SUResult res = SUModelCreateFromFile(&model, "model.skp"); for SUResult res = SUApplicationGetActiveModel(&model); and when I run it, res = SU_ERROR_NO_DATA, and model …

At what point in the load cycle are you getting a 0 pointer ? Ie, after the extensions load, SketchUp goes through any attached AppObservers and polls them for an expectsStartupModelNotifications() callback that returns true and if so, then checks if they have either an onNewModel or onOpenModel ca…
