How to: Improve Speed of AutoCAD Analysis and Import

Sometimes the import can be slow, especially with a lot of references and files that have many attributes. If you have attributes in the Model space that you do not need, you can speed up the analysis by filtering out the attribute analysis for the Model space, and only reading attributes for the drawing. Administrator access is often required to make changes to the server package.

Instructions

You can filter out the search for attributes not in the title block or in the model by following the steps below.

Option 1 – Analyze only named blocks (title blocks)

1. Locate the OcmDwgManager.ini file on the server located at C:\ProgramData\Open Domain\OCM Service\[CAD Manager]\Packages\Standard\Basic\FileManagers\DwgManager

2. Set AcadParseBlocksByName to the name of the title block.
   
   To get the name of the title block:

   i. Double click the title block within your AutoCAD drawing to open the Enhanced Attribute Editor window.
   ii. Copy the name located in the Block: section.

Option 2 – Exclude Model Layout Attributes

1. Locate the OcmDwgManager.ini file on the server located at C:\ProgramData\Open Domain\OCM Service\[CAD Manager]\Packages\Standard\Basic\FileManagers\DwgManager

2. Set AcadDoNotParseLayoutsByName to equal Model.
