In order to use this plugin you should have geo located boundaries of your site and digital terrain model in ".asc" file format. 

1. Prepare shared coordinates in your Revit project.

2. Draw the site boundaries.

3. Load ".asc" file.

If you do not provide the geolocated site boundaries, you can load ".asc" file which will be centered to your project's coordinates.

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.

Large .asc files import can slow down and freeze Revit for longer time. It is recommended to trim the terrain surface to a selected boundary.
