Dear all, I’m creating a custom SKP exporter to a proprietary file structure. I’m using the C++ SDK. Everything is going great but I’m at a loss for one thing, The transformations to get the points on the correct place in the complete model. As documented SUComponentInstanceGetTransform retriev…

I don’t have any experience with the SDK, but based on my experience with the SketchUp DOM from using the Ruby API, the parent of a component instance is a component definition, not the containing component instance. This means one single component instance can be placed on multiple different place…

Here’s a picture to illustrate what @eneroth is talking about. In this very simple model there are three Components, cleverly named Component#1, Component#2, and Component#3. The model contains one instance of Component#1 and two instances of Component#3, which nests one instance each of Component…

Thank you @eneroth3 @slbaumgartner That part I understand. The problem I have getting this into code. I can get all instances of all components, and get the transformations of the instances, no problem but this is incomplete data. So I would get 3 instances of Component#1 and 2 instances of Comp…

[image] rudidekruijf: What functions do I need to make the recursive path to go from model->instance->instance->instance? You are going to multiply the transformations together as you drill into each nesting level. Use SUTransformationMultiply and then apply the resultant transform to the ob…

And here is a thread that explains doing it in Ruby … [image] How to get components global coordination Ruby API i try some methods. firstly i use boundingbox.center, if the components have the same definition, the center values are the same. secondly i use transformati…
