The terrain data is at best at 50-foot intervals when it comes into SketchUp, which amounts to about 1 square mile at a time. Question: Is there an extension to bring in a larger mesh from Google Earth than the default size? (55:30)Īnswer: Unfortunately, no. It may help to export the grading/contour design to FBX and then from FBX into SketchUp. In general, however, SketchUp should read proposed grades just fine. Question: Will SketchUp work as well with proposed contours from CAD Civil 3D as it will with existing contours? (54:00)Īnswer: It’s hard to say without looking at the file. To export to Leica, you should export it from SketchUp as an FBX file. Question: Can the SketchUp grade be exported into Leica? (51:40)Īnswer: Yes, it’s possible, although it’s better to export to a DWG if possible. Note: Bringing contours into SketchUp from CAD Civil 3D can be a little trickier, requiring you to break the terrain into pieces. Using Artisan to flatten an area, and to select and paint vertices (49:50) Other valuable terrain tools: CLF Color by Slope and CLF Color by Z (from Chris Fullmer on the Extension Warehouse) (48:45) Using the DropGC tool to drop blocks (such as site amenities and trees) into the site (45:15)Īdding a fence using the Instant Fence tool (from Vali Architects) (46:55) You can export these contour lines to CAD if you want. Making contour elevations using the Contours tool (available from the Extension Warehouse). You can also use Soap Skin Bubble (another alternative to From Contour) for grading work. Grading the wall into the terrain using From Contour (36:00) Using the From Contour tool to create a grade (33:45) Using Tools on Surface from SketchUcation (one of Daniel’s favorite tools) to draw 2D lines on 3D terrain and create the extents of the site (31:26) (30:42)ģ1:26 – 45:14: Integrating Structures Into the Terrain (Re-grading) You can also use a tool called DropGC (available from Smustard) for this same purpose. You can use the up and down arrows on your keyboard to move objects straight up and down in SketchUp. Placing all the necessary elements into the terrain (29:30) (25:10)Įxtruding elements such as walls, buildings, steps, etc. This tool is more difficult to use than Artisan, but it’s also more accurate. Using the Instant Road tool (available from Chuck Vali’s website) to grade the road and select a predetermined road set. Highlighting the mesh with the Drape tool (from the Sandbox menu) and “draping” a road (21:40)Įditing and smoothing the road using the Artisan tool (available from the Extension Warehouse) (22:35) Turning on the road layer in SketchUp (21:30) This step creates a tighter, more accurate grid (although this tightness can also cause SketchUp to work a little more slowly). However: You can modify the grid to make it more accurate. Note: The main issue with Topo Shaper is that, though easier to work with, it creates contours that aren’t as accurate as those created by From Contour. Processing the terrain by selecting Topo Shaper (17:56)Ĭalculating the terrain and creating a mesh grid (square rather than triangular) (18:30) Note: Topo Shaper can handle many more vertices than From Contour can handle. Note: TINs in SketchUp are notoriously difficult to work with. Opening the Hidden Geometry (from the View menu) to examine the TIN (16:25) Using the From Contour tool to generate the contours and create a Triangulated Irregular Network (TIN) made of stitched-together faces (16:18) Using the Simplify Contours tool (native SketchUp tool) to simplify the contours brought in from CAD (15:55) This can bog down SketchUp and cause it to slow down. Note: When you bring in contours from CAD, they often contain too many vertices. You can obtain many of them from the Extension Warehouse.Ģ Generate terrain – Triangulated Irregular Network (TIN) to Meshģ Overlay roads, trails, walks – flatworkĤ Extrude structures like buildings, walls, and stepsĥ Integrate structures into terrain – re-gradeĦ Drop blocks and replace: Site amenities and vegetationġ4:43 – 21:12: Generating Terrain in SketchUpĢ ways to generate terrain in SketchUp (14:43):ġ The From Contour tool from the Sandbox menuĢ The Topo Shaper tool (available at ) List of Terrain Modeling Tools & ExtensionsĮxtensions are the SketchUp version of apps.
