Prevent DWG export creating families into blocks

[Lehtinen5BZBJ]

Hi,

Is there a way to prevent Revit from converting families into CAD blocks when exporting to DWG?

We have configured our DWG export settings to separate objects using a Layer Modifier by type and workset, e.g., "{Furniture}{Workset}". Somehow, the Workset name is applied to the block’s layer, but not to the layers of the individual lines within the blocks.

This is an issue because we need to filter the families by Workset name in Archicad. Unfortunately, the software reads the layer names from the lines within the block, which removes the distinction between families modeled on different Worksets

The easiest, perhaps, possible solution is to not let Revit create the blocks in the first place. I checked the basic DWG Export settings, but couldn't find any setting for that though. If anyone knows how to do that, or has any other possible solution for this problem, it'd be greatly appreciated.

Revit cannot directly prevent families from being converted into CAD blocks during DWG export. You'll need to manually explode the blocks in AutoCAD

That's a bummer.

In that case, is there a way to name the layers inside a block with the Worksets? Right now the Workset name is only in the block, but doesn't transfer to the lines inside the block.

With default settings this would mean:

- block line style of a chair: "I-FURN-Library"

- but opening the block in ACA, the linetypes are just "I-FURN"

We'd wish this to work as automatically as possible, as we need to do it many times in the future...

Revit is not focused on being a "better way to make DWG files".

Your best option is to create an application (script/lisp) to process the DWG elements within AutoCAD once the data has been exported to DWG.

Hah, yeah. It's a pity we need to play around with these ancient filesystems, when all that it's for is to transfer info between two modeling softwares...

But thanks. The script/lisp seems to be the best way indeed. I try to approach the problem that way.
