There are two additional recommendations I would make to the Autodesk solution below: use a Generic Model inplace family, and the import can be placed on an additional Subcategory to allow for easier control over visibility in the project environment.

Here is the Autodesk solution:

Issue:

You want to display cut 3D drawing models in section views. Revit displays the entire drawing without regard to cutting plane, both in section and floor plan views. 

 

Causes:

Revit cannot currently display cut 3D drawing models in section views.

Solution:

  1. In AutoCAD, run EXPORTTOAUTOCAD to export a DWG file.
  2. Import or link the DWG file into an in-place family.

If you want your entire geographically separated team to have access to the same linked files, you need to upload them to Revit Server. This also goes for CAD / DWG files, which will need to be imported into an RVT if you want to save them directly to RS.  2D DWG files can be referenced by Linked View in the host project if necessary.

Here is a bit of a workflow that may help:

1 Open the consultant model in appropriate version of Revit
2 Enable Worksharing (if it isn’t already)
3 Save As … 
a) if this is the first “save” of the consultant model to Revit Server, use a generic name like link-Structural.rvt and save onto Revit Server in the appropriate folder (if you have one for links)
or/ 
b) if this is an updated model, overwrite the existing consultant model, using current name in the Revit Server Link folder
4 Use Reload on this new Consultant model in Manage Links of Architectural (our) host model
5 Close the Shared Levels and Grids workset for the Consultant Model, like this:
 
6 Sync with Central.  The Consultant model has now been imported / updated onto Revit Server, and other team members should be able to access it.

10 Things to Know About Revit Server – The Revit Clinic

Removing and Replacing Models on Revit Server – The Revit Clinic

Have you noticed that (typically) Revit 2014 will only show Import Categories for those imports that actually exist in a view?

I think this is a great feature that makes things a bit cleaner when navigating Visibility / Graphics and looking for Imports etc.

Short post, but you know, there is always more to come 🙂  Over 250 draft posts, and about 100 more in my ‘to blog’ email folder…

Sometimes you will have some junk imported DWG definitions residing in your project.  These may be present due to the long history of the project, perhaps using Transfer Project Standards – View Templates, or just poor RVT model management.

How can you get rid of them?

There are various paid tools that will let you do it, but if you already have access to the Whitefeet Tools, you can use them to easily delete any import definitions (they don’t have to be DWGs) that you no longer want in the model.

Here’s how to do it:

  1. Install the WhiteFeet Tools, if you haven’t already.
  2. Open Revit
  3. Go to Add-Ins, Utility Tools (the W logo) and click on Management Tools
  4. Click on Manage Attachment Links
  5. Select the definition you want to remove.  Make sure to select a line with the Type ‘definition’. (See image below).
  6. OK and close out of the dialogs
  7. Once back in Revit, use the Manage – Select by ID tool and press Ctrl+V.  This will paste the element ID for that import definition.  The Properties Palette will show the proper import name, but everything will be grayed out.
  8. Press the Delete key on your keyboard
  9. Done!

Now, when you go to your VG – Imported Categories list, that particular Import will no longer be present.

Congratulations, your model just got cleaner!

Boost Your BIM has been posting some awesome stuff.  One older post shows you how to quickly purge your Revit model of Imports:
a FilteredElementCollector, a bit of LINQ, a transaction, and Document.Delete to get the imports (but not the links) out of the model.

Steve made a few interesting points today about Revit and DWG (Import) extents.  I previously posted about Revit accuracy and precision here.

However, did you notice this new setting when importing a DWG in Revit 2013?

If you UNtick the box that says Correct lines that are slightly off axis, then Revit 2013 will bring in the DWG as-is.  It won’t try to straighten things up to make the DWG more Revit-friendly.

Obviously, use this with care.  But for me, 9 times out of 10 I want the DWG to come in EXACTLY as it was drawn.

Oftentimes, you will want to flatten a DWG file before bringing it into Revit, so that Revit isn’t confused by all the Z-values… you can use FLATSHOT or the DXB plotter methods, as described below:

Issue
You want to create a flattened two-dimensional (2D) drawing of a three-dimensional (3D) model.

Solution
If you are using AutoCAD 2007 and higher, the FLATSHOT command is available to convert 3D solids to flattened 2D views. (Note this command is not available in AutoCAD LT.)

The other method to create a 2D drawing from a 3D model is to:

  1. Configure a DXB plotter using the Add-A-Plotter wizard

Read the rest at:
Autodesk – AutoCAD Services & Support – Flatten 3D model to 2D

Basically, the issue goes something like this:
Revit 2012 can’t find a linked dwg anymore. When I try to reload it, Revit says the file doesn’t exist. There is an other linked dwg in the same folder, which still loads fine.

Here are some relevant forum threads:

Here is one solution.  Well, its not really a solution, more of a method that can be used to fix this problem:

1) make view templates for the graphical overrides of the imported dwg (Overrides import)
2) remove the file from the project
3) save under new name
4) reopen the project and Link CAD the same dwg file
5) apply the view template for graphical overrides
6) check all views, if you imported to all views
7) redo dimensions, if there were any connecting the linked dwg with the model
