The first thing I notice is that it is not a model. It is an attempt to draft a set of 2D projections in a 3D application. (You are trying to use SketchUp for what Layout was designed for.)
2nd: The camera is in perspective mode, when it should be in parallel projection for this kind of 2D work.
3rd: The style used has it’s “Hidden Geometry” unchecked.
4th. The Steve component’s instance and definition is still in the model. (Should purge unused components.)
-
Screen-based Text objects are problematic in a 3D drawing. (They do not work well with Panning or Zooming.)
-
All text is point sized which looks strange when zoomed in. (They’d be better at say 12" height or so.)
-
All the text callouts are 3D objects which makes them hard to control in a 2D manner. (Which you realized.)
Basically you are trying to shoehorn a 2D multi-view drawing into a 3D modeling application.
There is another thread around here where we all list free or cheap 2D applications.
