In LeoCAD I can create multiple submodels. But how do I merge them or integrate one into the other? The release notes suggest that this is possible, but I can't seem to find out or find resources about how to do it.
The idea behind this is that I would like to create building instructions for the model using LPub3D. I would like to use submodels to make the building instructions easier to understand. I would like to show how a certain part of the model is built and then at some point integrate it into the main model. So far I have not managed to do this. The different submodels coexist separately and in LPub3D I have only access to the main model (i.e. the first submodel).
