Parameter Explanation:

Region: Select the range of the area where you need to construct TIN.

- Polygon Region: Define a polygon area, the key points located in the area participate in the construction of TIN.
Key Point Class: Select the key point class to participate in the construction of TIN.
Minimum Edge Length: If there is an edge in the TIN mesh triangle that is shorter than the minimum edge length, the triangle will be deleted. Combined with the maximum edge length parameter, it ensures that the generated TIN does not contain triangles that are too short or too long.
Maximum Edge Length: If there is an edge in the TIN mesh triangle that is longer than the maximum edge length, the triangle will be deleted. Combined with the minimum edge length parameter, it ensures that the generated TIN does not contain triangles that are too short or too long.
