Hi @zinnfandel , sorry for the late reply. @jlampel gave a great answer, and the only other thing I can think of is you might have “Only Render” turned on in the “Display” section of your properties panel. Hit “n” to open properties and make sure “Only Render” is unchecked. The other possibility is the light gray color of the armature may be blending in too much with the default light gray color of your building without material applied. You can try switching on Matcap (also in the “n” panel) to choose a different lighting scheme that might help.
