Turn Snaps Off on the Manage ribbon, and then use the keyboard shortcuts to selectively turn “On” the snaps when needed. This stops Revit from continuously looking for snap points when you are trying to navigate the model or draw new geometry.
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:
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.
Revit cannot currently display cut 3D drawing models in section views.
In AutoCAD, run EXPORTTOAUTOCAD to export a DWG file.
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)
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.
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:
Install the WhiteFeet Tools, if you haven’t already.
Go to Add-Ins, Utility Tools (the W logo) and click on Management Tools
Click on Manage Attachment Links
Select the definition you want to remove. Make sure to select a line with the Type ‘definition’. (See image below).
OK and close out of the dialogs
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.
Press the Delete key on your keyboard
Now, when you go to your VG – Imported Categories list, that particular Import will no longer be present.
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.
