Causes: The CAD file has values much higher than the 20 mile limit for geometry from internal origin that was applied for Revit. The values themselves are not a problem but the CAD file has reference blocks that refer to 0,0,0 which is the cause of not displaying the CAD link.
When you import or link the DWG file, Revit displays the geometry from the nested xrefs. The decision to import or link a file to a Revit project affects what you can do with the xref information: … If you link the file, Revit automatically updates the geometry to reflect changes to the xref files.
Is Revit compatible with CAD?
AutoCAD and Revit are interoperable and can be used together. They are commonly used together to incorporate designs created in AutoCAD within a Revit project.
Can you import DWG into Revit?
You can import data from other CAD programs into a Revit model. Supported CAD formats include AutoCAD (DWG and DXF), MicroStation® (DGN), Trimble® SketchUp® (SKP and DWG), SAT, and 3DM (Rhinoceros®). When you import a file, the format of the imported file may support varying qualities of geometry.
Why can’t I see my imported CAD in Revit?
Either by zooming to extents or closing and re-opening your file, you will be zoomed out so far that the CAD drawing (and your Revit model) are a tiny, invisible dot in the middle of your screen. To solve this, un-link or remove the CAD file.
When you link a CAD file to a Revit model, Revit maintains a link to that file. … This ability to retrieve the latest changes to a CAD file is the difference between linking and importing. When you import a CAD file, Revit uses the version of the file that you imported.
Open an existing model, and link another model to it.
- Open an existing model or start a new model. You will link another model into this model.
- Click Insert tab Link panel (Link Revit).
- In the Import/Link RVT dialog, select the model to link. …
- For Positioning, specify the desired option. …
- Click Open.
Is Revit harder than AutoCAD?
Revit is a much more powerful software, capable of creating 3D building models. … Managing changes in Revit is much simpler, since modifications are reflected on all existing views. In AutoCAD, design engineers may have to update several files if there is a change.
Should I learn AutoCAD or Revit?
A good way to look at the benefits of each tool is AutoCAD is great for 2D drawing, where only precise line work is needed, such as elevation detail drawings. Revit is great for modeling, generating cost schedules, collaboration and change management. In the industry of design and construction, competition is fierce.
How do you explode in Revit?
You can explode imported solid (not polymesh) geometry in the Family Editor environment.
- Select the import symbol.
- Click Modify | Imports in Families tab Import Instance panel Explode drop-down (Partial Explode) or (Full Explode). The 3D solids are now preserved as free form elements.
How do I edit a CAD import in Revit?
1. Open your CAD details and change them to 0 layers then delete the Hatch pattern in the CAD file. Clean up your CAD file before importing into Revit (By this we can get single line type in Revit).
