Revit models needing to generate .dwg exports

Revit models needing to generate .dwg exports

We are generating all our project files using Revit, but our deliverable are still requested as dwg format. Often the client does not dictate a layer naming or style standard, so what we need to generate is a .dwg file that looks exactly the same as our PDF's generated directly from Revit. Here's how we achieve it without any pain. (We ignore our old CAD standards, layers, line weight and linetypes and force Revit to make the CAD look the same)

 

We do not want to post edit our cad exports and there fore need the .dwg to look exactly the same as the PDF, this has not been an easy exercise and we spent a lot of time trying to map the layer names and style, here was a fast solution that gave us the output with no post editing!

 

Here's what we do...

 

Export Revit to .dwg

If you wish to export your Revit views to .dwg files and have them look the same as the Revit view for linewieghts, linetypes, fonts etc. them please follow these steps to get the best result.

From the application menu (The big 'R') select export, then dwg.

From the dialog, select the 3 dots next to the drop down for 'Select Export Setup'

Export Layer Options should be set to 'Export all properties BYLAYER, and create new layers for overrides'. This ensures of any elements have manual overrides, filters or other changes in the view to be exported the changes are retained.

We use AIA layers, but it's not important, just pick one that suits you.

Lines tab, pattern tab, text and fonts, ensure all are set to {Automatically generate ...}

Colors tab needs to be set to Trues colour if you want colours to map the same

Solids Tab, ACIS solids (Polymesh will result in 6 faces for a cubic solid, generating lots of additional lines that are not required. Also is a pain for anaylisis software,)

Units and Coordinates, we use shared basis.

General Tab, we select export rooms option, we hide scope boxes, reference planes and unreferenced tag, but leave 'Preserve coincident lines' unticked to ensure minimize duplicate lines.

If you are trying to map Revit exported views to a particular CAD layer name and style standard such as your Corporate standards, you will need to generate a mapping file.

Thanks for taking the time to submit your idea. Unfortunately, this idea did not get the support of the community over the last 6 months and as such we will not be pursuing it at this time. Please feel free to rework (titles and clear descriptions are really important) and resubmit this one down the road.
