Topo From Lines

Digitally signed app



This tool provides a quick and efficient way to use Autodesk® Revit® model lines or a CAD import to generate Toposurface elements.


After your model lines are created or the CAD is imported, use this tool to select those lines and then have a toposurface created.


The toposurface is created by placing 50 equally spaced toposurface boundary points along each line.


If the model lines are modified after the toposurface has been created, the Update command allows you to select a modified line and the toposurface and the tool will then update the toposurface geometry.


Note: This app uses a custom installer (and not the standard App Store installer).

    Interesteing plugin on slope lands and houses integrated in relief. thanks to make it free.

    when do you make for R2022 ?

    Hi - Glad you like it. I am migrating all my various tools into an open-source product with a single install. You can download the installer here (click on "view raw" to download it)

    thanks. I'll see your other plugins ! For me Topo from line is best used on wall plans to decide how the relief goes on one (or both) part of the walls (which is almost impossible with Revit basic tool).

    Great idea! Thank you for it!

    I can't find a way how it's working with Model Lines. I can't asign them at differnt levels. Could you explain a bit?

    Hi, Create the model lines at whatever elevation you want them to be to define the shape of the surface. Then run the tool and select the lines.

    Great tool! Any chances we can get it for Revit 2015 or 2016?

    Harry Mattison (Publisher) | July 08, 2015

    Coming soon!

    Usefull app, thanks for posting it. unfortunatly I can't use it to add point to an existing topo. otherwise this would be a good way to add in some actual pads. if you could select some lines to create contours (as the tool does now) and other lines to place points at 0 relative to an existing surface then you could use it to create the top of a pad and the bottom/top of a batter. that would be all I need to do all my topo.

  • CAD Import?
    Bradley Touchstone | April 29, 2014 Verified Download (What's this?)

    It would be amazing if it could work with cad imports as well.

  • OK job
    Buch Richard | December 30, 2013 Verified Download (What's this?)

    Does a great job on simple designs. However, anything complex, the results are equal to that of Native Revit Topo's

    Harry Mattison (Publisher) | March 18, 2014

    The Revit Site API provides access to create the same toposurfaces that you would create with the Revit UI. This tool creates topo-points on the selected curves to allow the designer to build contour lines instead of placing points individually. But there is nothing in the API that would allow creating surfaces better than what native Revit would produce.

  • Superb

    superb will help a lot

  • Excellent.

    great way to create landscape. remember that: "Circles and ellipses that Autodesk® Revit® creates as a single curve need to be manually split into two lines before being used in this tool". good job Harry, as always.
