Align topography to elements picked in the model.

General Usage Instructions

Launch the app from the ribbon button.

Select if you will use a single element or edge(s) to align your toposurface.

Set the divide edge distance. This value is the maximum spacing a straight edge will be divided by. Curved edges are automatically tessellated.

Set the vertical offset from the selected face.

Choose if the topo should be aligned to the top or bottom face of the element.

Click Align to Element. Click on the topo to be aligned then click on the element or edges.

To have a floor follow topography Align to Topo.  You’ll be prompted to pick a floor and then a topo and it will add the topo points to the floor to make the floor shape edited.

To use Points from Lines you must place model lines (lines and curves only) and then must be physical located below the topo surface.

Reset region asked for you to pick an existing topo surface in the existing project phase and a new topo surface (usually created as a graded region). You pick a rectangular region in a plan view and topo points within that region are deleted from the new topo surface and new points copied across from the existing topo surface. This will not reset boundary points.

Additional Information

Known Issues

While you can select a family the addin attempts to find the topmost or bottommost face to align the topo surface too. Depending on the complexity of the family this can lead to unexpected results. Families which are joined to other families can also generate errors. Pick edge has been included to allow the topo to be aligned to an individual edge within families or elements.

Version History

Version Number Version Description


Added support for 2024 using toposolids instead of toposurfaces


Added a new command to make floors follow topo.# Improved points at intersection for straight walls / faces. Removed archisoft tools naming


Added support for Autodesk® Revit® 2023.


New command Points at Intersection


Added support to specify the spacing between points along model lines and to offset points in the Z value above selected model line contours. This allows 2D contours to be drawn on a datum level and projected up to the desired elevation.


Re-compiled for Autodesk® Revit® 2022 and in future will just be updated as new Revit versions are released from a single app on annual subscription. This build allows the addin to work with Revit 2019, 2020, 2021, 2022.
