Make sure your Sketchup file is setup properly. We convert components to one object, but keep all nodes in a group. That means that it's still ok to use a group if you want to group e.g. all walls on a floor, but try to use components when you import furniture, vegetation,... You can easily convert groups to components by using the SelectionToys plugin.
When working with Sketchup, you can easily connect through our custom-made Plugin. You can find this plugin in your portal where all the information and downloads are gathered.
Under the section downloads, you can find the latest version.
Installing the plugin.
