Chooses the specific smart item in the catalog and its 2D symbol file based upon the type of parent outfitting (pipe, cableway, cable tray, or duct), calculates the size of the hole trace based on results of the Best Fit Clearance Rules, then places the hole trace object in the model. For more information, see Best Fit Clearance Rules.
Best-fit symbols are delivered in the Visual Basic project [Programming Resources Folder]\Programming\ExampleCode\HoleMgmt\Symbols\HMBestFit\HMBestFit.vbp. The project is compiled into HMBestFit.dll, delivered in the [Reference Data Folder]\SharedContent\Bin\HoleMgmt\Symbols\Release folder.
The HMBestFit ProgID is also bulkloaded into the catalog as the symbol definition for individual smart items. When the best-fit symbol is selected from the catalog, the hole trace shape and size is computed using the algorithms in HMBestFit.dll. For more information, see Hole Traces Workbook.
The BestFit.cls class module provides the symbol definitions in the catalog without using a 2D symbol file.
The DefinitionRule.cls class module contains the best-fit definitions and computes the symbol size.
You can modify the 2D symbol file selections and the best-fit definitions.
