Bill, hopefully it is clear that 3D Text is geometry just like the parcel and building footprint lines in your model. The geometry does come in as components. Peter's suggestion to make separate scenes and image exports for the model and the text is a great way to manage this. You can create a separate layer for the 3D text and turn that layer off for the view of the model. then turn off the layer(s) for the model and turn on the 3D text to create a second scene and then export both as images which you'll combine in post process.

You should look through some plugins from Thomthom, e.g. Plan tools Edge Tools Cleanup For multiple push pull you can use Joint Push Pull from Fredo6.
