Null Triangles by Angle/Length (Seed)

This option is used to Null (remove) Triangles by Angle and Length with a Seed Point. The seed point is the starting point for the nulling by angle and length, which is particularly useful for nulling internal areas of a tin.

Tin Boundary

This tool is used to create a Boundary string/s around a Tin, to ensure that the unacceptable triangles around the edges of the tin that have been nulled will be saved if the tin is retriangulated. The video below will show how to create a Tin Boundary string/s and save it to the Tin for [...]
