Differentiate the graded region by placing it on a layer created for it (Graded_Region). ADJUST LINE WEIGHT. Using the Toposurface tool, you can generate points on the toposurface from the linked AutoCAD file. On the Modify | Edit Surface tab, click Tools panel Create From Import drop-down (Select Import Instance). Before you jump up and down telling the surveyor to “Do your job properly” and demanding the file in 3D you might be able to impress everyone with your skills and get quicker results. He demonstrates how to set up a project and add the grids, levels, and dimensions that will anchor your design. Learn how this is much more efficient than creating such points manually. Using linked AutoCAD site plans is a quick and effective way to create accurate topography in Revit. Share. Replace deprecated ParameterType with ForgeTypeId Once done, these will leave us with points at the roughly the correct spatial coordinates and elevations. Remember to select the appropriate import units c. For positioning use Auto – Center to Center. I’ve saved mine as txt2point.lsp, In case you were unaware, the command for a lisp routine is defined after the code (defun C: so in the instance of Geobuilder’s lisp routine, the command is Convert_Text_to_Point.

Revit Instructions: Open Revit and link the .dwg file in revit. To create a toposurface by importing contour data. You can modify the topography using the edit surface tool, it’s up to you how you handle it, in this instance I chose to delete the 0 elevation points however you may want to fix up the elevations of the points to make sure all the gaps have been filled in and the topography is as complete as possible. Copy and paste the lisp code into Notepad and save it as something you’ll remember. … And there's a real easy process that we can use … to take that site plan information from the dwg … and turn it into something that Revit calls … a topography surface. The next step is manipulating the data in Excel so that the points import in to Revit correctly. Embed the preview of this course instead. Video: Creating topography from a DWG link. a. Insert tab > Link CAD > Link CAD Formats dialogue box opens (Fig 2). Although it was a fairly lengthy how to, the entire process from start to finish should take no longer than 10-15mins which in most cases is much quicker and far less painful than going into battle with the surveyor over a bunch of 0 elevation points. When the DWG is ready, use the following workflow to create the topography. Thank you for taking the time to let us know what you think of our site. Finally, discover how to annotate your drawings so all the components are clearly understood, as well as output sheets to PDF and AutoCAD.

Same content. Use up and down keys to navigate. Create a Toposurface by Importing Contour Data Revit analyzes the data and places a series of elevation points along the contour lines. I've found it easiest to simplify and clean it up manually in CAD before importing. Removing these points is simple to achieve by using the Quick Select tool. Using linked AutoCAD site plans is a quick and effective way to create accurate topography in Revit. The last thing you want to be doing is telling everyone that the data is rubbish because “these random spots I decided to look at are 5m higher than the surrounding surface, the surveyor must be wrong”, Using your preferred workflow, strip out all the information from the DWG file not related to the surface. You can create toposurfaces in 3D views or site plans. Create a new project with a simply flat topo element. If necessary you can edit the topo points in Revit too. Once you’ve subtracted the base point coordinates from the coordinates of the survey points, the end result should look similar to the screenshot below which lists out all the points in coordinates that are relevative to the project base point. A lot of people misunderstand how Revit’s coordinate system works which often leads to problems  when working with data between AutoCAD and Revit. The two main options you have for automagically generating a topography surface are to either import from a DWG file that contains 3D surfaces – generally these would be topography triangles, or to generate from a list of points in a CSV file. He also shows advanced techniques for modeling stairs and complex walls, adding rooms, and creating schedules. To change the display of your points from dots to crosses, you can change the PDMODE variable. Survey drawings could contain spot information for elements such as buildings, trees, fences and other non-surface information so you need to make sure that you’re grabbing only the information that is relevant to the topography surface. Assigning “real-world” coordinates to a Revit project requires some input and an understanding of how Revit “sees” its location. 1. … So it's going to start by linking in a CAD file … from your civil engineer. Save as cloud model from BIM360 Team to Docs Workflow: Create Topography from DWG in Revit 2016 using Dynamo Today we will see how to create a Toposurface in Revit from DWG file coming from Civil 3D and contains the contour lines. Same content. Using the Toposurface tool, you can generate points on the toposurface from the linked AutoCAD file. In Revit. To finish up, you’ll need to review the imported topography and tidy up the output. If you’ve taken a look at the new Revit API or tried to update your apps to the new version, you may have seen a lot of errors about units because of API code that Autodesk deprecated in the 2022 API. Under the “Modify|Edit Surface” menu, select “Create from Import”. 3.

The guide assumes knowledge of setting up site coordinates and linking. To view or change toposurface or subregion properties, open a 3D view or a site plan view, and then click Massing & Site tab Model Site panel (Toposurface). 6 & 7. This means to process our data in Excel we need to subtract the coordinates of the project base point from the survey point we exported from AutoCAD. In this section you will be creating a helical mountain.To creates a mountain out of the topo tools you first have to create a “guide” family. 1. Select the output location and file type. In this video you'll learn how to use the Revit … Same instructors. You receive a DWG file from a surveyor, and you need to get it into Revit. Remember to always make the topo surface bigger than the site as it can then be trimmed back to the boundary lines using the Split … Once the .DWG file has been imported into Revit, navigate to the “Massing & Site” Tab. This means we’ll have duplicate points, some with a Z value of 0.0 and some at the correct Z value. However, if you receive a file from an outside source, such as a civil engineer, you'll need to create topography from a DWG link in Revit Architecture 2015. Learn how your comment data is processed.
