![The Create Toposurface from Point Cloud Dialog Box.](https://1515823925-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-Lga_i3Obkwb7iGSAwzP%2F-LhATda78SdtRWGkpn-v%2F-LhATm34hf4ClzidtlSV%2Fimage.png?alt=media\&token=7822f8b6-9884-4306-b2b4-c8c1ccefccdf)

This tool will analyse a Point Cloud instance and create a grid-type-layout that will be used to interpolate the points and create the topography surface. The more Iterations, the smaller the iteration distance will be and therefore more points will be created.

**Horizontal or Vertical:**

* Total Distance: The Approximate horizontal size of the Point Cloud Instance.
* Iterations: How many divisions the interpolation will create to determine the points.
* Iteration Distance: The calculated distance of each iteration. This will update as you change Iterations.

After the surface is created, you can delete the points on top of buildings, trees, cars, etc to clean things up a bit.
