I am updating our company template which at this point involves importing a lot of CAD details and "Revitizing" them. That being said, all of the company linestyles from CAD come in and stay as that linestyle, making this template file very cluttered. Is there a way to have the incoming linestyles just map to an existing Revit linestyle that is close? That way, the file doesn't get full of AutoCAD lines...
thanks.

Have you looked at "Setting Line Weights for Imported DWG or DXF Files" in you help file? It may be useful.

I hadn't seen that. Thank you.

I also suggest laundering cad imports through a blank project.
I absolutely hate it when cad hatches, patterns, and line types slip into a project and clutter everything up.
edit: oh. nevermind. You're just updating the detail library to avoid this exact problem.

Ok, so upon further inspection...doesn't that just determine what LINEWEIGHT to bring in the imported linestyles at? I am talking about having the lineSTYLES converted to existing Revit ones so that I don't have 200 different linestyles from CAD imports called things like "A-DETL-4MM" and "A-DTL-NOTE", etc.
Basically, I want to import a CAD drawing with CAD linestyles and when I bring them into Revit, instead of Revit creating new linestyles based on the CAD names, it just converts them to "1" or "6" or "hidden" or "thin"...

and yes, I agree...I do need to start going through a blank project, but shouldn't "purge unused" essentially clean up all that crap anyway?

Purge unused will only remove items/types that are -completely- unused. If you have one dashed detail line segment out of 30 million in your project using a cad import line style, it's impossible to purge. So when we long ago rushed to import all of our cad details into revit, we brought in a decade's worth of misc. cad details with tons of line styles and hatches, and now those inconsistencies are spreading like an incurable virus to every revit project as we transer drafting views between projects.
So being really rigorous at the outset of bringing over a library is a good idea...

Ok, makes sense. So let me ask this: is there a way to select all instances of a linestyle (say, A-DTL-4mm) and convert them all to another linestyle (say, Fine)?

I've been doing it one detail at a time. Import CAD, explode, select all linework, use filter to only select one lint type, change it to what I want it to be. Rinse, repeat, until all DWG line types have been changed. When I'm done working in the file I purge, then go through Object Styles and remove the DWG styles (purge doesn't seem to get rid of them for some reason).
I've been working directly in the details file and it seems to work ok, but if you wanted an extra layer of security (and you won't have to worry about purging anything) you could explode and change line types in a junk file, then copy/paste into your details file.

The best option (thanks to AUGI forum search): Ideate Explorer
http://ideateexplorer.com/features/
Just downloaded the free trial and now I can globally select linestyles in one click and change them, then purge the old stuff. Amazing. Revit really needs to incorporate this kind of indexing power. Thank you all for your insight.
