I know this is an older thread but maybe others will see it. In regards to the base views not showing objects after blocking them together, this makes sense if the view base was made by selecting objects rather than using everything in the model. Creating a block effectively 'hides' the solids from the base view and the new object (a block) wasn't originally picked so it is excluded.
To update the base view, pick on it and use the Viewedit command, which is named Edit View in the Ribbon, then type E for sElect, this will take you to model space, select all objects or just the ones that are now blocks, hit enter. The views will be updated.
