I would absolutely advise that a good detail library/manual can save a lot of time on a Revit project. Copying the latest project is NOT a good workflow since you will build up an overload of linetypes, fill patterns, reference planes ... and many other objects that can be difficult to "clean" out of your file. Remember that you can salvage some of what you did in CAD but you will end up much further ahead if you use Detail Items instead of lines and hatches like you did in CAD.
Hopefully this will help:
we have a similar issue (who hasnt?) - what we decided to do is keep the acad library and issue sheet in a folder within our template file. then when a new file is opened all the acads are available - someone goes thru the standard details to identify which ones are relevant. these are loaded (linked acad) onto drafting views and sheeted up from there. we put all the items onto one layer and removed the hatches - otherwise revit just fills up with unwanted layers and linetypes and hatches - often the hatches dont come thru 'properly' anyway.....
we keep the dwg numbers the same so that eg AD3_104 is always the same detail in whatever project it appears
often a 'standard detail' will need tweaking for a particular instance. this can easily be accomplished within the folder without affecting the library
there is a bit of an issue with a consistent 'look' as revit details look different to acad imported dwgs which with a bit of TLC can be managed
hope this helps
we have linked in our cad details into drafting views and then created a REVIT Native Detail Library
define specific line styles and patterns to all your details for consistent output
we then create a master detail Revit file that we can import views from into our projects.
the linking process has proven to be more work than it is really worth
Text Formatting issues text styles and line weights become to inconsistent
all detail Items and symbols are coordinated in Revit and now we rely less on AutoCAD linking or inserting.
we have used interns to assist in this task as a training exercise with very good success.
We have gone through a process similar to what the others have stated. What started out as hand-drawn "standard" details (copied onto clear acetate and taped up on mylar) were then redrawn in AutoCAD (as individual files, with "starter" sheets with often used details for interior partitions and doors/frames externally referenced). We now have almost all of those details redrawn in Revit, and maintain them there, exporting to CAD when changes are made so the updates are available for AutoCAD-based projects as well.
From the very beginning, the details were grouped by the specification section of the primary element in the detail; in Revit, we have a separate project file for each such group, with all of those details drawn in drafting views. These can easily be transferred to a given project file, grabbing just the ones that apply to that project. It works fairly well, much better than during the transition, when many details were not yet available as native Revit details.
We are proceeding with a ACAD to Revit conversion strategy...
We have an pre-existing detail library that are not formatted details in ACAD that only exist in model space. But it is organized by spec section ... so we are using that as a starting foundation.
I have upgraded these detail so they are linked through Sheet Set Manager and easily published as a catalog.
Now I would like to create a acad to revit translation so I can easily convert them into revit ... right now we are manually doing this as a need to do process...
As we assemble the newly converted revit details ...we will lay them out on sheets, so they are easily inventoried....
to be continued ....
Our workflow - old DWG details imported, unpinned, exploded in drafting views. The resulting drafting views are then cleaned up, with lines assigned to our standard linestyles.
Each Revit file would contain related drafting views, arranged in categories - for instance, Jamb and Sill details, would be in one Revit file with categories for different types of Jamb and sill details.
At the end of it all - Purge Unused RUTHLESSLY. That is the only way to get rid of all that ACAD gunk. Also purge out sheets, families, ANYTHING that is irrelevant.
Use Insert from File to drop the drafting views into your project.
I would avoid this method as much as possible.
if you cant avoid this approach be sure that your AutoCAD files are as clean as possible.
BYLAYER and scaling will have an impact on the final result.
if you link in the details and use the selection tool (pick lines) from the link you wil not need to spend so much time later cleaning your files from all the exploded AutoCAD garbage.
A more consistent input will give you a more consistent output.
filled regions, render materials, linestyles and patterns from imported exploded elements and text styles can create a real mess in the end.
too much clutter in a file that should be managed as a clean resource.
Absolutely. Which is why you purge ruthlessly.
I've done it with both methods and it is much easier to prevent the garbage from getting into your library than it is to get rid of it.
