Mike, lets say we are talking about the bees building comb on plastic foundation, or no foundation with starter strips, in your honey supers only, for the sake of this topic, and not in the brood nest. If you have a strong hive, during a good nectar flow, it won't matter what you have in between the frames, they want to build honey stores in your supers. Now, I acidentally put a medium atop two deeps with just frames, no foundation or starter strips and this particular hive didn't draw any comb in that super. Some on this site say their bees will and have drawn comb with foundationless frames and no starter strips, but I prefer wooden frames, and I use plasticell foundation. So far, I haven't really had a need to harvest cut comb, so I will stick with that set up for now.
One more thing, I have read here that some will spray their plastic foundation if the bees aren't drwing on it with sugar water, or smear a little honey on the plastic and this will entice them to draw.
