Import DWG to Revit

Introduction

Although geometry created outside Revit usually doesn't have the editing and data possibilities like geometry created within Revit, it can still be useful to import building parts that were created with AutoCad for example. This will give the opportunity to get a complete model of the building and create the technical drawings within Revit. There are two main file types that you can use to export from Acad:

• DWG
• Dxf

General preparations

The most important step when exporting your model from Rhino to Revit is the preparation. It is paramount to optimize your model. The geometry will become one object in Revit, making it impossible to add different materials to different parts of the imported geometry. To be able to use different materials on imported geometry in Revit, we will have to import it in parts. One part for every material. Other things to keep in mind are:

• Only import the part of the model you need
• Keep the level of detail as low as possible

Settings for importing DWG Files

1. Select the Floor Plan you want the geometry to be placed at.
2. Insert » Import CAD
3. Set Positioning to Auto - Origin to Origin.
4. Set Files of Type to DWG Files (*.dwg).
5. Browse to the location where you saved the dwg file. Select the file.
6. Click Open
7. Make sure that the scale is set to meters
8. To view the drawing correctly you have to change the line thickness.
