Best approach for Stone Veneer component "hatch pattern"?

[cazana]

Hello, my firm loves to draw stone as sort of a "patch work" instead of a hatch since sometimes stone hatch patterns can be repetitive and busy. We have a DWG file with preset stone polyline components and use them as shown in the attached image. We want to recreate this in Revit since we've fully transitioned over. I can only think of doing either of these options:
1. Import the DWG and keep it in a drafting view to copy and paste into the elevations. (will this slow down the model immensely? They import as individual lines instead of a polyline, is there a way to join them, would a masking region be better?)
2. Make them into a detail item family and so they're combined and have instance based parameters to toggle through each one. (would a face-based generic model be better for areas where stone would be in front of another materials that isn't stone?)
Is there any other better option? We prioritize aesthetic and love the way it was in cad. We want to find the most efficient and best performance-wise way to solve this issue. Thanks in advance!

Create a bitmap of the stonework and use that bitmap in a Material.

You can create your own Hatch Pattern matching exactly what you have drawed in CAD with the Add-in pyRevit, it's really easy to use:

They don't want a full hatch guys... look at the image. 

I think using detail items OR a single detail item with instance parameters as you said would work the best. The one problem is there wouldn't be an automatic way to cut flat sides along edges as you show, so I'm not sure how important that it. You'd just have to have some pre-made options for those conditions.

You could make this as a Face based generic model family with nested detail item families showing the linework/graphic.

This would allow you to place it one time and they would show up in all elevations of that wall.

The one issue is that you would not see the linework when not looking orthogonally at the wall. You could do it from model lines but then you would see them everywhere and would have to turn them off/hide them in some views like plans/rcps.
