alterations or additions to existing buildings). STEP 2: Create the Revit Toposurface. Here is my revit project. Step 2 - Link in the 3d dwg file of the site information. Then, click on Graded Surface (on the massing & site Tab) select the topography, and on the dialog that appears, select the first option, see below, and simply accept the graded region like that pressing on the green "accept" symbol. Create seperate building project file(s) and a seperate site project file then link them together. It is a real shame we cannot turn the topo boundary line off because sometimes the points given by the surveyor does not take the topo beyond where we set the view's crop region. By default they are in the same location. Select the triangle survey marker icon and move it down to z = 0 of the linked dwg. This is often a good option to say “yes” to, but may not always provide desired results. Both ends of an open loop must lay on the boundary of the surface. This can be changed to show the correct levels based on the position of the position of the Survey Marker. Can automate this with access the Revit API Add-in/ app: Topo Align . Full Revit users can select the linked dwg. e.g. Fixed an issue where incorrect topography geometry was created when linking a Civil 3D published topography which had large coordinates. Linework representing site contours at the correct elevation (z value) or, preferably the original triangulated network from the surveyor (ask them to include the TIN information in the dwg file). Provides a container of all Revit built-in FailureDefinitionId instances. See Step 5a below. You can Edit the Slope Value for each line by selecting it or turn off the slope for that boundary entirely with the “Defines Slope” option (available in the top tab or properties tab). Simple as that, the levels are now reporting the correct RL's. The test being that when True North, the linework representing north in the linked dwg should be oriented straight up the view.

First, lets discuss 2 methods for setting up your project to manage your site information: Method 1 - Integrated Building & Site Select the “Image” command from the “Insert” … This can be done seperately in plan and elevation. It may help to set the view to wireframe to see all the linework in the linked dwg. Click the Green Tick to Finish Edit Mode. Click (Pick Lines) or use other sketching tools to create a subregion on the toposurface. All to often people tell me how they go through the tedious process of selecting all their levels and using the move command, then have to select all their views/details/text etc and move it all up or down to align with the new location. © Copyright 2021 Autodesk Inc. All rights reserved. Editing the Boundary of Toposurface in REVIT. Before you create topography in Revit, make sure that your Survey Point is set to a known elevation on your topography. Get answers fast from Autodesk support staff and product experts in the forums. 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 Surface tool giving nice clean accurate edges to your site. This is suitable for small scale jobs where there is very little or no chance of the building being relocated on the site (e.g. Place the base of the rotation somewhere on the linework indicating north and rotate it so that it is pointing straight up the view. From Visibility/Graphics turn on Site > Base Point & Survey Marker. Select one of the imported dwgs and you should see the topo be modified to follow the helical edge. Managing your Site Information Establish the true north and the correct levels (RL's) from the site information. LOCATE THE INTERNAL ORIGIN. It is often easier to edit topography in a Site view or a 3D view. For example, you can use subregions to draw parking lots on a graded surface, roads, or islands. Click (Pick Lines) or use other sketch tools to modify the subregion on the toposurface. Create Revit Topo Surface from the site information. Revit enters sketch mode. . However, Revit offers no mechanism to create custom room types that have overrides. I hope factory does something about this in next release. Step 5 - Geographically locate your project from information in the survey dwg It is not strictly necessary but it will help to explain what is gong on in the next steps. The Subregion can be created very quickly by tracing the Floor boundary. Toposurface is critical when developing your Project Site. I have an existing (demolished) toposurface that does not cover the entire area of my site plan. You can also give an offset value if required. Linework for the boundaries if you have it. Link in the 3d dwg file of the site information provided by the surveyor, or from some other source. Custom script or Dynamo Page 10 of 32 In the “Project Browser” change the “Floor Plan” to “Site”. The splitting boundary drawn would result in a self-intersection of the surface boundary. Create a Toposurface Subregion. Drawing a reference plane while editing the surface will allow you to snap the plane to the surface points. Create Revit Boundary Lines with correct bearings and distances Create Revit Topo Surface from the site information. Now you can create the Revit Property lines by tracing over the boundary linework in the linked dwg. From an elevation or section view, select a level, edit the type properties and change the Elevation Base from Project Base Point to Survey Point. Revit Topography. However graphics-wise, it doesn't look very good on the plan. This is one reason for having some linework in the dwg at z = 0. The simplest way of trimming an existing Toposurface boundary is to use Split Surface in the Massing & Site tab: Here we can use the Pick Line utility to specify the split line: Then you just need to close the loop and select the green tick, creating a second surface. Create Revit Boundary Lines with correct bearings and distances. Autodesk is a leader in 3D design, engineering and entertainment software. Select the desired topography, and click Link. ElumTools can place discrete calculation point locations on any surface, work plane, topography or boundary line in your Revit model. Please edit your splitting lines to correct the problem. Use the Rotate True North tool. Step 4 - Move and rotate the Topo Surface & Linked dwg to be correctly positioned around your building. Click (Pick Lines) ... Click Modify | Topography tab Subregion panel (Edit Boundary). Otherwise, make sure your lines are inside the topography bounds in plan view, simple test: click on inner topo > Edit Surface, try adding additional topo points outside your inner topo surface manually – Revit will not let you. Also, the ground floor level is still at 0. To translate this article, select a language. On the Properties palette, in the Shared Site field, hit the button that says Annotating the topo surface enables easy visualization as well as helps in Site Analysis. straight up the page. Figure 10: Selection steps for helix Revit is a proprietary software package developed by Autodesk, an industry monopoly that consistently underdelivers when architects, engineers, and builders attempt to execute a BIM project. Create a Shared Coordinate Site Adjust the annotation families to show the correct levels and coordinates. Used for jobs when there is a posibility of the building being repositioned on the site (almost every new build I have been involved in has been repositioned in some way during the DD or CD stage). In the Revit Project working on “Level 0” or the equivalent level, draw “Model Lines” or “Reference Lines” to represent the boundary lines of the site. I'd love to be able to hide the boundary line around the edge of the surface, but have the contour lines remain visible. Make sure there is some linework drawn at elevation 0 that can be used as a check datum. Elevation All other annotation families that report levels and coordinates can do this as well. This can easily be changed from wall faces, to centerlines, to wall cores. In Revit you will need to have a Floor, a Toposurface, and a Subregion with the same boundary as the Floor. Now that you are aware of this super secret internal origin, you … Revit LT users will have to do follow a slightly different process. You can create toposurfaces in 3D views or site plans. MEP Analytical Systems © Copyright 2021 Autodesk Inc. All rights reserved. I have located the site in plan so the building is in the lower right corner and rotated it so the boundary is aligned with the building (you can just see the cyan bounday lines in the linked dwg). I'm always amazed when people don't know about this very easy process of changing a building's Levels to reflect the actual RL's of the site. It is part 2 of my RUGwell July 2015 presentation How to get Wellington Area Site & Terrain Information, which should be read first. In the Link Topography dialog, navigate to the topography. I typically link dwg files positioned Center to Center. Create Revit Topo Surface from the site information. Step 1 - Create a Building Project in Revit The Base Point is indicated by the circle with the cross and Survey Marker is the triangle. All room elements in your model will calculate their areas to the same boundary condition throughout the model. You can also use the Relocate Project tool which effectively does the same thing. Fixed an issue where rooms and spaces could lose or no longer detect a linked model boundary after reload latest when using Revit Cloud Worksharing. That's fine for the fact that the new work is just in a small area of the site. Create area boundary lines in either of the following ways: Automatically create boundary lines: Revit will offer to automatically place Area Boundary Lines along all exterior walls. True North has not been set so it is the same as Project North, i.e. Incorporate the site information in the same file as the building project. Adjust the annotation families to show the correct levels and coordinates. Creating subregions does not result in separate surfaces. Fixed an issue where incorrect topography geometry was created when linking a Civil 3D published topography which had large coordinates. Creative Commons Attribution-NonCommercial-ShareAlike 3.0 Unported License. Plan Surveyors cringe when they hear this as it goes against the grain that we should move the site when they have put all that effort into correctly geo-locating the dwg file. Revit LT doesn't have the the Shared Coordinated tools so manually move & rotate the Survey Marker to the 0,0,0 origin of the linked dwg. Secondly, how do you edit topography in Revit? No part of the open loop can intersect or be coincident with the boundary of the surface. 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. If the linked in site information dwg file was set up as listed in step 2, it can be used to geographically locate our revit project. Step 5a - for Revit LT users Lines can be outside the bounds of your topography only if there is one topography instance in your model or your topo instance is not surrounded with another topo instance. But once drawn, the reference plane cannot be modified in the Surface Sketch mode. Toposurface in Revit can be created using multiple methods. It is much easier to move the site around the building. This one simple step has extracted the cordinate system from the dwg file and stored it in the revit project as a Shared Coordinate Site. Fairly simple. Tell us about your issue and find the best support option. But don't worry, it all gets sorted out in the next steps. You can actually do this while editing the surface. by selecting the appropriate variation from the command menu, or, to any boundary type by simply clicking the main command button. First of all, before creating any Building Pad, set the phase of the Topography to a Phase (I assume Existing would be the right one) and then set the phase of the view to the next one. ElumTools locates points specifically by the associated boundary type (Room, Space, Region, etc.) Make sure your properties list the Roof as hosted on the correct level. Open a site plan that displays a toposurface. Create a Toposurface by Importing Contour Data, Software installation, registration & licensing. Step 2: Create Area Boundaries. Example. (I'll have to detail this in a seperate post). Step 3 - Create a Topo Surface We typically do not move the building elements in Revit. In the Site Plan view or any plan view that you can see the linked dwg and more importantly, the linework representing north, set the View Orientation to True North. Connect, consult with, and hire trusted industry experts on the Autodesk Services Marketplace. Also used for projects where there are more that one building on the same site. From an elevation or section view, use Visibility/Graphics to turn on the Site > Survey Marker It's based on the default ootb template. Method 2 - Linked Building & Site Check this in plan and section (you may have to do a Zoom Extents and change where the section is cutting through) You can now set any plan view to be oriented as Project North or True North. Emre Ozkan GAUDREAU INC. Revit Implementation Group Revit is a great tool to create and modify Toposurfaces! With OpenBIM still yet to mature, here is a list of criticisms of the software's limitations. The elevations and cross sections are still showing 0 as the level for the ground floor, which means they are based on the project Base Point. The Toposurface tool defines a topographical surface (a toposurface) using points. Linked RVT Files Fixed an issue where rooms and spaces could lose or no longer detect a linked model boundary after reload latest when using Revit Cloud Worksharing. The easiest way to do this is to draw a reference plane along the edge of the Topo. Get answers fast from Autodesk support staff and product experts in the forums. Autodesk is a leader in 3D design, engineering and entertainment software. Step 7 - Adjust the Level Display In cross section, I have moved the site down so there is an even cut and fill. Once the .DWG file has been imported into Revit, navigate to the “Massing & Site” Tab. This is not strcictly neccessary but is a really good check. Hence you can see the topo boundary that in essence doesn't exist and confuses everyone. Move and rotate the site information to sit correctly around the building. Topo Align has three features, Align to Element, Points from Line, and Reset Region, all of which edit Topography. By now, most people in the industry would have heard of flux.io, a spin-off from X (formerly Google X). Civil engineers typically use a 3D CAD program to model topography for a site. Managing your Site Information. This should contain: Click Massing & Site tab Modify Site panel (Subregion). How to get Wellington Area Site & Terrain Information, Software installation, registration & licensing. Share and vote on ideas for future product releases. Tell us about your issue and find the best support option. Before we do this we should make sure Revit's Base Point and Survey Markers visible. Tips and Tricks Interface Importing Data Modifying Toposurfaces. 1., Choose Massing & Site > Modify Site > Split Surface and select the topsurface created in the earlier steps, 2., It goes into edit option, use Pick Lines option in Draw to trace the area that need to be deleted, 3., Trace the bottom curve, 4., Connect the edges with a line, Adjust the annotation families to show the correct levels and coordinates. Spot Elevation, Spot Coordinates and Contour Labels. Select the topography element, select edit surface, and select Create from Import. Finally the easy bit. Create Revit Boundary Lines with correct bearings and distances. Also a good idea to have some linework that indicates north. This post explains how to use survey information in a dwg file, either from a registered surveyor or from Koordinates.com, to geographically locate your building on the site. You should see that the triangle Survey Marker has moved to map onto the 0,0,0 of the linked dwg. Recently, flux.io updated their site extraction tool which pulls data from free open source datasets, Open Street Map and NASA.When combining with Dynamo, it couldn’t be any simpler to pull in topography information to your Revit model.. Create a Topo Surface from the linked dwg using the Contour or TIN linework from the linked dwg. The Y axis of the saved coordinate system should be indicating north. Under the dropdown menu, choose “Select Import Instance” and select the … Open a site plan that displays a toposurface. Revit enters sketch mode. In some ways it doesn't matter which method you choose because it is quite easy to split a project up into seperate building and site files or conversly merge them together. Establish the true north and the correct levels (RL's) from the site information. To translate this article, select a language. Under the “Modify|Edit Surface” menu, select “Create from Import”. A subregion defines an area of the toposurface where you can apply a different set of properties, such as material. The choice of method to be used depends on the available source data. Click (Finish Edit Mode). Sketch a single closed loop that does not touch boundaries of the surface, or sketch a single open loop. And back in Dynamo, all you need is this very simple definition: BUT, be sure that you run it in Manual mode. Click Insert tab Link panel (Link Topography). In fact most of my jobs start out as method 1 for sketch planning and then get split up as method 2 at DD stage. To create separate surfaces that can be edited independently, use the Split Surface tool. Step 6 - Create Property Lines The following image shows a toposurface that has a subregion, shown in gray.
