Export Assemblies to OHDA

Out of the box, Overhead Design Analysis (OHDA) provides a user interface to export ArcFM assemblies for use in OHDA models. The default behavior is for an administrator to add an ASSEMBLYCODE field model name to a field in the geodatabase for OHDA to consume. You can programmatically create custom logic to change the field model name or control how assembly descriptions are processed, and the out-of-the-box user interface will utilize this custom logic. The code snippet below demonstrates how this works.

If your data model does not match this structure, you can modify the code sample and use it to extract this information from your database and send it to OHDA for analysis. These data extractors are used when you use the Export to Overhead Design and Analysis tool in ArcMap to extract these fields out of the poles and cables.

Assemblies with custom data miners for OHDA must be located in the bin directory where the OHDA files are installed. You can verify where this folder is by checking your registry key:

On a 32 bit machine:
HKEY_LOCAL_MACHINE\SOFTWARE\Miner and Miner\ArcFM8\MMBinDir
On a 64 bit machine:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Miner and Miner\ArcFM8\MMBinDir
