The ''Preferences'' menu can be reached by using the '''Preferences...''' command in the ''Edit'' menu and then selecting the ''TINs'' item; or it can be reached by using the '''TIN Settings...''' command in the ''TINs'' menu. The following settings are available: | ||
*''Retriangulate After Deleting'' – If this option is on, the region surrounding the vertex is retriangulated as each vertex is deleted. Otherwise, the triangles adjacent to the vertex are simply deleted. | *''Retriangulate After Deleting'' – If this option is on, the region surrounding the vertex is retriangulated as each vertex is deleted. Otherwise, the triangles adjacent to the vertex are simply deleted. | ||
<!--*''Adjust Boundary to Include Exterior Vertices'' – If this option is on, the boundary of the TIN is changed so that the new vertex becomes part of the TIN if a new point is added outside the active TIN. If the new vertex is in the interior of the active TIN, the vertex is automatically incorporated into the TIN.--> | |||
*''Adjust Boundary to Include Exterior Vertices'' – If this option is on, the boundary of the TIN is changed so that the new vertex becomes part of the TIN if a new point is added outside the active TIN.

*''Default Z-Value'' – The default z value is assigned to all new vertices created with the '''Create Vertex''' tool. | *''Default Z-Value'' – The default z value is assigned to all new vertices created with the '''Create Vertex''' tool. | ||

*''Extrapolate For Default Z On Exterior'' – If this option is on and a new vertex is entered outside the TIN boundary, a default z-value is extrapolated from the TIN to the new vertex. | *''Extrapolate For Default Z On Exterior'' – If this option is on and a new vertex is entered outside the TIN boundary, a default z-value is extrapolated from the TIN to the new vertex. | ||
*[[GMS:Editing a TIN#Adding_Breaklines|''Breakline options'']] – The options below define how GMS will add a breakline when the ''TINs'' | ''Advanced'' | [[GMS:Editing a TIN#Adding_Breaklines|'''Add Breakline(s)''']] command is used. | |||
**''Add supplementary points'' – Adds vertices to lines through which breakline passes to create a TIN that will take the breakline into account. Lines will be adjusted to prioritize breaklines. | |||
**''Swap edges'' – Swaps edges to take breaklines into account instead of adding new points. This usually eliminates any lines through which the breakline passes. | |||
*''Minimum length ratio'' – The ratio that GMS will use to determine which triangles to select with the [[GMS:Editing a TIN#Deleting_Triangles|'''Select Boundary Triangles''']] command. | |||
