changing the default length in duct work

[we.revitt]

Hi everyone

My question is about how can I change default length in the part of fabrication? In my country, common metal sheets which are used for duct works have the size of 2*1 meter which is somehow different. 

How can I change this default length in CAD MEP  so as to use in Revit and totally, have a full control on duct's length ?

Default length settings are stored in the specifications. 

Go into your database.

1. Select fittings
2. Specifications
3. Select your duct specification if setup.
4. Change the standard straight value. This is normally 100mm longer than your required length to allow for connector folds. You will have to play around with this to suit your settings.
