Attached is a small tool, called Sketchup Model Extractor (SME) I have written using ConvSEO which makes the process of extracting Sketchup models to .dbo objects much simpler.
Please ensure you read the SME_README.TXT file included.
I initially wrote this in order to be able to remove the unrequired parts of a model then ConvSEO creates anyway as it has no way of knowing what is of use and what is not. For instance the inside of a box created in Sketchup will often be invisible in the scene but ConvSEO still creates an object for it, usually textured in the default material.
The current beta version loads a Sketchup exported doc.kml file using ConvSEO, it then creates a 'tree' list of all the objects in the model. You can navigate around the scene, select objects, hide them and then save them out to .dbo files, either one at a time or in groups or even whole models. There is even a function to re-fix objects origins as ConvSEO sets all objects origins to 0,0,0.
When a group of objects is exported SME also generates a DBPro source code section which can be used to load them back in and texture them correctly etc.
Hopefully you will find this as useful as I have.
