How does it work?
Step 1: Learn how to use the pre-built Revit families (such as TitleBlocks, Elevation, Section and Details Markers and other, all included as part of the conversion utility – specific to your standard) which will be compliant to the standard that you are trying to convert to.
Step 2: The second part makes use of the Revit Export to CAD conversion utility to map the Revit object to AutoCAD layers, as close as possible based on the standard you are trying to export to. However, as you know, Revit messes up the Text Styles, Dimensions Styles, layers and many other items; so there is a 3rd step.
Step 3: The final step is our conversion utility (which can be run in batch mode using ScriptPro), which takes the DWG file and cleans up the messy DWG created by Revit, in order for your DWG file to pass any QA check.
