How to Catechumen a 3D Revit Model to second Vector Line Drawing
2d Linework Overlay Examples
So, you lot're trying to have a 3d model in Revit and you want to export information technology as 2d linework… Here's a quick mode to do that!
This is a fox that I apply frequently for creating 2D wireframe drawings from 3D perspectives. Oftentimes, I overlay these lines as part of a collage to requite another layer of information that I can easily edit. Hither are a few samples of how you could use this technique:
DISCLAIMER: This method does not guarantee perfectly clean exports of 2D linework. The result that yous get from using this method ultimately depends on how you take created your model in Revit. The quantity and blazon of 3D geometry that you accept in your model volition affect the linework quality.
With that being said, let's get started.
For this method, we volition be using AutoCAD and Revit. If you are looking to edit the resulting linework in Illustrator, at that place is a simple method for doing that which I encompass at the finish of this tutorial.
Place a 3D View on Sheet in Revit
First, open up Revit and navigate to the 3D drawing that you want to export linework from. This volition be either a perspective or isometric view. For this example, we will utilize a perspective view.
Create a new sail to place the 3D view onto, and name it accordingly to keep your files clean. When nosotros export this sheet, the name of your exported .dwg file will correlate with the sheet name that y'all cull.
Next, elevate and drop the view onto the sail you just created.
Export the Canvas + 3D View From Revit
In the main navigation bar, select "File" -> "Consign" -> "CAD Formats" -> "DWG". Select the location that you lot would similar the .DWG file to exist stored.
It may accept some fourth dimension to export, but that depends on the complication of your 3D geometry. If information technology takes a LONG time to export, that's a skillful indicator that you may have a lot of geometry in your file. Always exist witting of how much detail yous want to evidence, and be sure to turn off or hide geometry that you won't necessarily need for your 2D linework cartoon.
One time the cartoon is finished exporting, navigate to the folder and yous may find ii .dwg files have been exported. Revit defaults to exporting both the 3D model and the 2D sheet as separate files.
Open the Exported Revit .dwg in AutoCAD
We want to open the 2D sheet file in AutoCAD. Right-click the file, select "open up-with", select AutoCAD equally your program.
In the "Model Space" of AutoCAD, you should run across the drawing that you simply exported from Revit, along with the canvas.
Notation: FOR SCALING 3D DRAWINGS
Perspective views are ultimately scale-less. Isometric views, however, tin can take a calibration cistron. It is of import to check your scales when moving between programs, as units tin can sometimes change.
In your cartoon, you will see that Revit has exported linework and surfaces that are actualization equally hatch patterns in AutoCAD. You will typically need to make clean upward the drawing a bit. Since Revit and AutoCAD work well together, you will notice lines and hatches are separated into layers based on your organization in Revit.
Use the Quick Select Menu to Clean Upwardly The AutoCAD Drawing
If yous want to become rid of the hatches quickly, go to the "Properties" tab. Open the "Quick-select" menu, which is the icon with the lightning commodities (considering… speed!). For object blazon, select "Hatch". In the "Operator" department, select "All" and hit OK.
If done correctly, all of the hatch work in the drawing should exist selected. Merely select "Delete", and all of the hatch work will be removed from the cartoon. Now you should be left with a pure line cartoon.
Transfer Linework to Adobe Illustrator
At this point, this may be all that y'all need, but if yous would similar to transfer this drawing to Illustrator, here'southward how you tin do it:
To motion your linework into Illustrator, go back to AutoCAD and type command "Select", "All". Follow with "Command"+"C" to copy the linework to your clipboard.
Open up Illustrator and simply "paste" the linework.
Illustrator typically groups everything together, so if you desire to edit these lines individually, be certain to right-click and select "Ungroup".
From hither on, yous're all fix. You tin can now edit these lines in Illustrator to your center's content.
Good luck!
