The Create New TIN Ground Model dialog is used when creating a TIN ground model from other data. This includes the process of converting a Grid Ground Model to TIN format, or thinning an existing TIN ground model.
The dialog is displayed when you right click a TIN Ground Model group (in the Model Group window or Explorer window) and choose New | Ground Model TIN from the context menu.

| Field | Description |
|---|---|
| Name | Name of the TIN ground model to be created |
| Ground Model Grid |
Used when creating a TIN Ground Model from an existing Grid Ground Model. Existing ground model from which new TIN is to be created. |
| Ground Model TIN |
Used when creating a TIN Ground Model from an existing TIN. Existing ground model from which new TIN is to be created. |
| External data source(s) | Used when creating a TIN Ground Model from external data.
Name - path of external data field Type - type of external data file Use lines? - enforce polylines as TIN edges |
| Thinning |
Used when Thinning a TIN Ground Model. Check the Show sizes box to enable the thinning options. Current Size - displays the number of points contained in the existing ground model Point Reduction - adjust percentage to set how much smaller the new ground model will be Compressed Size - an estimate of the number of points in the new ground model |
| Grid res. factor |
Used when converting a Grid Ground Model to a TIN. The Grid resolution factor is used to lower the resolution of the TIN ground model, where the Grid Res. Factor x Grid Base Cell size corresponds to the minimum size to be considered when importing values from the Grid ground model. |
