Source code of Model Duplicate with Attributes application for 12d Model. Dependencies: set_ups.h – Available in your 12d Model install folder standard_library.h – Available on the 12d Forum here:  https://forums.12dmodel.com/viewtopic.php?t=1196 !! NOTE !! These files cannot be directly run from within 12d Model. For that, you need the compiled version here or you need to compile it yourself (Utilities→Macros→Compile from the 12d Model menus).

Compiled 12d Model application (aka macro) simply duplicates a given model to a new model with an option to also copy model attributes.  Options in 12d Model currently (V14C2j) allow for duplicating of models, but none support also copying over the model attributes.  The model attributes can be used for storing various meta-data and user-defined information, but are also used extensively by the Three Waters tools in 12d Model, particularly the stormwater drainage analysis.
