With the release of Revit 2020 a new feature has been added which enables you to import PDFs into views. We’ll be looking at this process and how vector- and raster-based PDFs are imported.
Process to import a Vector PDF:
The process is very simple in the fact that you go to the view you want the PDF to be imported to.
In my case I’ve opened an Architectural template and opened the Ground level called Level 1. Then go to the Insert ribbon tab and look for the red PDF tool in the Import panel.
I then browsed to the vector-based floor plan I created earlier by exporting a DWG file to PDF. Using AutoCAD. Once you have selected the file a dialogue box appears as below. The only setting you can set is the DPI which is the resolution. I set it as 600 dpi. Click OK.
It will then process the PDF and ask you to place the PDF in a very similar process as placing an image.
Once you have placed the PDF and you select it you can Enable Snaps. This will allow you to snap to the endpoints of the walls, for instance.
You’d want to do this if you want to trace over the existing PDF lines using the Revit Wall tool to draw 3D walls over the 2D PDF lines. In the image below, I’ve started tracing over the PDF’s 2D lines to show the use of the grip to create Revit Walls.
One thing to note is that the PDF is inserted in the Current View only. So, if you open a 3D view the PDF will not be shown in this view.
Looking at the properties of the inserted PDF you can you change size settings and also if the PDF is placed on the Foreground or Background. If the PDF is placed on the Background it will be behind any regions and 2D annotations you might draw over the PDF.
If you click Manage Images, you’ll notice the same tools exists as when Inserting and Managing Images.
Process to import a Raster PDF:
The import process is similar to that of the Vector PDF import. In the example below I’ve imported a scanned PDF drawing. One thing to note is that the Snapping option is not available when selecting the PDF. This is because you have imported dots that looks like lines (Raster PDF) instead of lines (Vector PDF). In the image below, I’ve zoomed into a part of the raster PDF to show the dots.
So to trace over the Raster PDF you’ll just have to zoom in close to the corners and click over the lines as accurately as possible as it does not allow snapping.
With regards to the processes to Manage the PDF and setting the size properties of the PDF remain the same as with the Vector PDF.
The feature to be able to import PDF is very handy as you can easily trace over an existing PDF.
