5. 1. This great post from the Revit Kid showcases how to use Lineworks to get proper depth effect. From here on you can Save the CAD file and take these points directly in Revit to generate topography. Go to Insert Tab on the Ribbon and select Link CAD (or Ipmort CAD doesn't seem to matter here) and browse to find the Topography file you saved from AutoCAD. To make internal origin visible, click View tab > Graphics > Visibility/Graphics, or use the VG hotkey. In your Revit site model, go to any elevation and uncrop the view. Change to a 3D side view and move the nodes vertically, in elevation, to the divided node. DISCLOSURE: CADMapper is a website that can save architects, designers, and planners tons of time by automatically generating 3D information for over 200 cities around the world. So after a successful internship I've been hired at this company, spending my time mostly in Revit. Found inside – Page 104Be aware that topographic surfaces cannot display surface patterns ... corner of the topographic surface, and change the Elevation value in the Options bar ... This value determines the elevation of the point being placed. 6. The guide assumes knowledge of setting up site coordinates and linking. 3. Found inside – Page 13-3Label Contours: Adds an elevation label to the selected contours. FYI: Contours are automatically created based on the ... Creating topography in Revit 1. 5. Revit is so broken in so many ways. The most easier way to comprehend this is to explain to yourself like this: There is a piece of land in the real world and is represented by attached Survey Point. You can also orbit the drawing to check that the topo lines create a legible surface. Before you create topography in Revit, make sure that your Survey Point is set to a known elevation on your topography. How to create and update landscape elements, including topography, hardscape, curbs, parking, and plantings. (The points and their elevations are used to create the surface.) 3. This blog will highlight some of the common questions and cool tips found in the process of transitioning our office to Revit. Let me tell you how to fix this: Revit 2010 has included handy new hidden elements in elevations called project base point and survey point in the form of a little circle and a little triangle. Found inside – Page 229To label the contour elevations, select Label Contours ( )from the Design bar, and click two points as if to create a section through the topography. I have been trying to get Revit to allow me to assume a FF ground level elevation of 100' (instead of 0') and maintian Real Sea Level elevations when using "shared". . Figure 12: Divided node and topo point locations. You design your project, you used the relocate project command, and you placed you Topography in the project while you where in your main level plan. 4. It should end up in the right place, throw some label contours on it and check it out. The only way I can get the numbers to work out is to "move" (relocate) the project 100' up and cheat the Project Base Point 100' less than real. It's on a steep site and the foundation must be in the native soil. I did my first topography in Revit and was delighted that the topography automatically cuts in any section I have produced. Revit TotD - 6.24.09: Project Elevation vs. Actual Elevation. Again to remedy this, manually change the project base point in elevation by clicking on the circle and changing the number to whatever you want it to be. In Autocad, delete everything except the hatch pattern. All Rights Reserved. REVIT FOR PRESENTATION Katia Gard, The Buchan Group . Your topography base point will be based on this level's floor. This elevation information, available as HGT files in 1°x1° tiles, can be used to generate topographies in Autodesk® Revit®." . Join Shaun Bryant for an in-depth discussion in this video, Using site and topography, part of Cert Prep: Revit for Architectural Design Professional. To modify the topo, simply change to a top down view in 3D and edit the topo and place points at each divided node. Looks janky. Assigning "real-world" coordinates to a Revit project requires some input and an understanding of how Revit "sees" its location. If the label contours are still off, play with changing the labels parameters from shared to project and visa versa. Have you every had a topographic model within Revit not display the secondary contour lines? Create the topo surface. Home » Articles » Revit Tutorial: Importing Topography. The only way to keep it consistent is to move the levels. Click on the circle and verify that the elevation number is relative to the distance you used to relocate your project. The project base point represents just that, the project base point. Then, use the relocate project command if you haven't previously done so. An alternate solution would be to manually edit the topography in Revit-- in an Elevation view or 3D view oriented to the side, do a window select of the points at the elevation you desire to change, and then change them. Absolute elevation refers to the Project Base Point, however most (all) siteplans we recieve are based on the Survey point. Topographic Surveys primarily include elevation contours or points. Levels are system families that are built into the Revit software and system family parameters cannot be edited (at least not that I have… Click on the check mark in the ribbon menu and your topo surface is complete. Now, when you click Okay you will notice the level will dsiplay the elevation based on the survey point (29'-0"): I have worked on projects where the elevation starts at a random number like 10' - 3/32". Software ver: Revit 2014 Edit: For future Revit-redditors wanting to know the answer. Join Paul F. Aubin for an in-depth discussion in this video, Topography settings and graphics, part of Revit: Tips, Tricks, and Troubleshooting. Revit Building >> Technical Support. When we receive their CAD file for a site, we have to import it into Revit to create a topography surface that we can then edit. Revit Topography. CADMapper generates 3D models that can be used with AutoCAD, Sketchup, Rhino, and . How can one create a site boundary contour line in elevation that represents the topography without having to simply draw a line over the topography in section? Found inside – Page 306A common workflow you may encounter when creating the topography context ... elevation to be used in the process of generating a toposurface in Revit ... Found inside – Page 11-3Label Contours: Adds an elevation label to the selected contours. FYI: Contours are automatically created based on the ... Creating topography in Revit 1. If your main level elevation is at 643'-0" it will stay at that elevation. A slight annoyance in Revit is that you can't add a spot level to a topography in a section view. Choose override graphics in view> by element… from the context menu. Elevations in Revit can be measured from either of these points. I am doing structural foundation work on a new chapel we are designing. Define reference elevation for points on toposurfaces When placing points for a toposurface you can chose between Absolute Elevation or Relative to Surface. Throughout the book you develop a two story law office. The drawings start with the floor plans and develop all the way to photo-realistic renderings similar to the one on the cover of this book. This way, you can use it to indicate the Sea Level elevation of any point. Inspect the CAD file the civil engineer gave you. The Toposurface tool defines a topographical surface (a toposurface) using points. An Image of a Tree can be used in Elevation or plan. The topography is probably already oriented to true north and you'll want to preserve this orientation for rendering accurate sun angles. Select the Create from Import dropdown and then click Select Import Instance. Open Revit. In the Link Topography dialog, navigate to the topography. You'll still need the point cloud in Revit to model buildings and street furniture, etc. Go to the Insert Ribbon and click on Import CAD.

If you do not see them in elevation, try showing the hidden elements (i.e. Then you simply punch in the Z values (i.e +1234mm) into each point, rather than do maths on each point rather than (like you have to at present) subtract the topo's "original/base" elevation from each Z value you have (which is obviously a pain, and won't annotate/report the elev. How to get your spot elevations and topography lines to read above sea level, and keep levels reading 0'-0"Revit files:http://www.turbosquid.com/Search/Artis. If you do use a mesh or 3D lines to create a Topo, Revit simply takes the points from those elements… the lightbulb on the bottom of the screen) and then zoom to fit (ZF on the keyboard). Look closely at the two topographic images above. When your dealing with a model someone else did...you have to ask yourself two questions: How long will it take to fix someone else's mistakes? 1. Found inside – Page 93Select the point at the outer corner of the topographic surface and change the elevation value in the Options bar from 20'-0" [6000 mm] to 10'-0" [3000 mm]. Who has the most to gain by using Revit in the landscape. These are the contour layers that you made a note of in Step 1. In the 3D view I was able to make the Topo surface transparent so I can see the footings in the dirt. The following video shows a workaround for this. DISADVANTAGES of these two elements being independent of each other: It can be very confusing when you are trying to show both your building and the contour labels as the ACTUAL values. 2. Revit 2020.2 and later. This will not change the location of your project. These are the settings I used to get 10’ intervals shown as a darker dashed line.

Found inside – Page 324A common workflow you may encounter when creating the topography context ... elevation to be used in the process of generating a toposurface in Revit ... Click Insert tab Link panel (Link Topography). When it comes to topography and terrain modeling, Revit is no longer intuitive and practical. THE PROJECT BASE POINT AND THE RELOCATE PROJECT FEATURES do not go both ways. Back in July, I posted about the Topo Align app, which is a great little app that you can download from the Autodesk app store, for only $1.99. Show both the existing and new elevation for a very large number of positions on a site plan. The image can also be a scanned hand drawing. There seems to be some other reference that it is using that I can't find or change. The most easier way to comprehend this is to explain to yourself like this: There is a piece of land in the real world and is represented by attached Survey Point. Faces are made up of THREE points. Site has coordinates and location settings preserved after IFC export. But I prefer taking spot elevations in excel and do some local-level subtraction and then import it in the Revit. 3.
