The properties of custom ARX objects of our 3rd party HVAC design software are not coming to Navis, so i guess want to make a COM DBX plugin. Couple of questions:

1. are COM DBX plugins called also when NWDOUT is done or only when opening a dwg with Roamer?

2. why was the DBX_01 api example removed from version 2009?

3. Document COM Interface.pdf part 8.3.1 says that i need lcaccomdbx.tlb, where can it be found?
