AutoCAD MEP

[#1]

I am using MEP2013. I would like to change the flanges on ductwork sections and ductwork fittings to be 20mm. It seems as though the default flange upstand from the ductwork is currently set as 50 mm. This is causing problems when drawing ductwork in tight spaces. How can I reset the flange upstand from 50 mm to 20 mm. This would need to be set as a connector style presumably, but despite considerable searching through MEP2013 I cannot see where this can be changed/set. Anyone help me on this one?

Thanks.

On the design tab of the properties palette there is an option to set the flange dimensions in the advanced section when you start the ductadd command.

Thanks for the reply. Yes I was aware of that but what I would really like to do is set a range of fittings and ducts with a default flange heaight of 20mm.

I have looked at the xml file but I am not sure what is the best way of setting up a new range of ductwork fittings, and duct to default to use a 20 mm flange.

Those options are not set in the xml file.  They are only available on the properties palette.  The properties palette remembers your last choice and uses it the next time you start to draw ductwork.
