How the 'Use in Surface' property of code affects the surface creation

Points, lines, and areas can be added to the Input List of objects used to create a new surface and calculate its triangulated wireframe in the Create Surface dialog. Codes of point type, line type or area type applied to respective objects feature the Use in Surface property of the code along with code type specific parameters of this property (Breakline for line type and Exclusion Area for area type). The status of the Use in Surface code property affects how a new surface is calculated.

Note: Review and change the status of the Use in Surface property in the Code dialog (to open, click > > , highlight the desired code in the list and click the Edit button).


Point
When points (b1 and b2) with point type code are added to the Input List of objects for a new surface creation, these points are either used in the triangulated wireframe calculation or not, depending on the state of the Use in surface property:

Linework
When lineworks with line type code are added to the Input List of objects for a new surface creation, these lineworks are always used as breaklines, regardless of the Use in Surface and Breakline statuses:

Area
When area with area type code is added to the Input List of objects for a new surface creation, this area either defines the outer boundary of the triangulated wireframe, or defines an exclusion area that is excluded from the triangulated wireframe calculation:

The Input List in the Create Surface dialog displays the information on how the added object is used in the surface.
