Default Family and Part

Question

I know this is probably simple and I'm sure I knew it at some point but, how do I change the default family and part when I am trying to place ductwork or piping? For example, I am trying to place some dust collection ductwork but everytime I start a new duct it reverts back to Duct; Supply-New. I know it automatically changes to the family/part you are connecting to but what if you are starting a new run and are not connecting to anything?

John, 
 HVAC_FAMILY_DUCT_DEFAULT is the name of the configuration variable that sets the default Family/Part when selecting the duct tools or duct fitting tools. You can set this to just the Family name [ = Duct ] or the Family/Part name [ Duct::Supply-New ] If you set it to just the Family, then it will default to the first part alphabetically the first time you activate a duct or duct fitting tool, but should stay on the active Family/Part as you switch between different duct/duct fitting tools as long as the active Family matches the configuration variable. 
 I have not tried undefining the variable as Jeff D. did, but it sounds like it is working for him. If you wanted to do this, you could just add "%undef HVAC_FAMILY_DUCT_DEFAULT" to one of your configuration files.
