Adding bubble holes and voids

- Concrete is an imperfect medium. What we do with concrete is to pour it into the molds after mixing, often on a truck on the way to the building site, and then vibrate it into the molds to make sure it fills them completely. What we get as part of that process, and also part of the mixing, are small air bubbles that later show up as small voids in the surface of the concrete. Additionally, if our forms have any kind of a grain or pattern, as they often do to them, that is embossed into the concrete. What I'm going to do is to make a pattern of bubbles for my forms here. What I've done here so far is to make a layer of formed ties and panel joints, and then I've also grouped all of my panel colors in a layer set called Panels. Now I'll hide Layer 1 and Background, and make a new layer, and this'll be my Bubble Generation layer. I'll turn off my other layers so I can see this clearly, and fill this layer in by pressing Shift+F5. I'll fill it with some 50% Gray, and I'm going to run…
