In this episode, I'll talk about add-ons that you can use in addition to your block library. In some cases, an add-on may even replace a part of your library. In my field of water and wastewater plant design, I use mostly pipe fittings of all sizes and materials. There are plenty of add-ons out there, so I'll just touch the surface in this episode on what's available.
