Bring your designs to a whole new level with the Land F/X SketchUp Connection. We’ll go through the workflow for a detailed 3D model based on a full grading plan with contextual grading. You’ll then learn how to take the plan to a point at which you can continue with your favorite renderer for a photo-realistic image. We strongly recommend watching both the Basic and Intermediate segments of this webinar to get the most out of the concepts covered herein.

Creating a User Coordinate System (UCS) in both the main drawing and the Xref to the same location (8:20)
Sending layers to SketchUp (example: buildings, walkways, and contours), making sure we have the correct project selected (8:45)
Tips for optimizing a design with contours created in AutoCAD Civil 3D in order to export successfully to SketchUp (10:45):
- Use the highest level possible for contour smoothing (but keep in mind that smoothing can cause contours to overlap, which can be a problem in SketchUp). Therefore, you’ll need to go through and make sure that contours are not overlapping.
- “Swap edges like mad” to mimic organic landforms as much as possible.
- Use grading groups and elevation from surface to merge into existing terrain (avoid assemblies, which add too much complexity).
- For retaining walls, use feature lines along the front, back and top. Avoid vertical faces if you’re going to move the design into SketchUp.
Note: Civil 3D puts the contours on different layers, and SketchUp retains those layers. (14:15)
Starting a new SketchUp model and saving it into an existing file/folder directory (14:53)
Verifying the Support ID and SketchUp library folder in the SketchUp settings, and verifying the Land F/X project (15:55)
Importing the layers into SketchUp (16:30)
Checking the elevations of the contours in the CAD Properties (Note: Each contour should be entirely at the same elevation). (17:20)
Using the TopoShaper extension (available from Sketchucation) to build the contours in SketchUp (You can also use the From Contours tool.)(18:30)
Making changes to the surface grid to allow it to pick up more contour detail (20:26)
Closing off all open faces (23:25)
Creating a grid with the Soap Bubble tool to stitch the proposed contours together and softening/smoothing the edges (24:30)
Adding color (26:20)
Stitching the contours into the existing site using Google Earth terrain (26:55)
Using Tools on Surface to stitch the site to Google Earth terrain (32:30)
The result of stitched-together site and terrain (35:08)
Copying the site and pasting it into the Google Earth terrain (36:34)
Splicing the site into the landscape (41:20)
Preparing the spliced site outline for Soap Skin Bubble (44:30)
Creating a connecting grid with Soap Skin Bubble (47:30)
Smoothing the edges and adding color (49:20)
Exporting other linework from CAD into SketchUp (example: buildings, pavement, wall, pool) (50:15)
Pushing the faces of the imported linework up above the terrain (53:30)
Intersecting the faces and adding color and materials fill graphics (54:00)
Exporting the planting design (57:51)
Importing the plants into SketchUp (58:20)
Adding and placing tree symbols from the components library (59:20)
Question: Bringing large files into SketchUp can make the lines act “fidgety.” How can I combat this? (1:00:30)
Answer: Try exploding blocks so you’re working with just lines and polylines. Then turn them back into polylines using the PEDIT command. Then try exporting them into SketchUp
Question: How to match the origin in CAD with the origin in SketchUp? (1:03:00)
Answer: Use theNew UCS tool to create a UCS at 0,0.
