Triangulate segment to a point

This function allows you to automatically triangulate from a selected segment to a selected point.

The Triangulate To a Point function is another technique which can be used to close the ends of an open 3DM Closed 3DMs are significant because a volume report can be generated from them. Also, slices taken through a closed 3DM will always generate closed segments.

The Triangulate To a Point function can also be used to accurately model `pinch outs' in geological lenses.

To run this function: Choose Solids > Triangulate > Segment to a point, or...

  • In the Function Chooser, type TRIANGULATE TO A POINT, and press ENTER.

Position the pointer and select the point to which the segment is to be triangulated. This will display the prompt:

Select the segment which is to be triangulated

Position the pointer and select the segment which is to be triangulated.

Result

Adjacent triangles are created from the first point selected to the points on the segment selected. The triangles created form a conical shape, with the vertex of the cone being the first point selected and the base of the cone being the selected segment.

The following prompt is redisplayed:

Select the point to which the segment is to be triangulated

The Triangulate To a Point function will continue until the function is cancelled.
