Designbotic Terrain is a tool for Autodesk® Revit® 2020 - 2024 which creates geolocated toposurface from ESRI grid files (.asc). 

ESRI grid files downloaded from GIS services usually cover very large areas and contain hundreds of thousands of points. Importing that amount of data into Revit is, least to say, problematic and that is why we prepared the tool.

This Designbotic tool lets you load just the portion of an ESRI file that you need. In order for it to work, you need a .dxf file with a geolocated plot that will adjust the survey point of your project. The plugin will precisely position the terrain surface and trim it before loading to Revit, which greatly saves the resources.

The plugin also allows importing ESRI grid files without geolocation and cropping, but the terrain files usually cover extensive areas and contain hundreds of thousands of points. Importing this amount of data usually freezes Revit.

Large areas with a large amount of points can significantly slow down the performance of the addin.
