Looks like you should be feeding it the duct element, not the name of the duct element.

there are a few thing there…you need a mechinicalsystemtype instead of categories, something here, and be sure you have dynamoironpython package installed 2.7 version 2.5

allright you feed in a string, try feed in the mechinicaltype element and ducttype element…

this one will more easier if you are using library OpenMEP, python now is more headache:
