Split by Line

Source file: split-by-line.htm

Split by line allows you to divide a surface using a line as a reference. The line can be straight or composed of multiple segments. Planes are projected from the line segments and used to cut the surface into two pieces. Various methods are available for defining the projections used for cutting the surface.

Note:  This tool cannot update texture coordinates around the cut on UV textured surfaces, giving the appearance of an imprecise cut.

1. On the Labs ribbon tab, go to the Geological group and select Split by Line.

2. Select the surface to be cut.

3. Select the line to be used.

4. If the Line and Surface fields do not auto fill, drag the objects to their respective fields or manually type in their names.

5. The default projection direction (normal of the plane fitted to the line)  will automatically load. Otherwise select another method from the Projection direction choices.

   
   

   • Two points: Define the direction by specifying two points.
   • Facet: Make the direction perpendicular to a selected facet.
   • Axis aligned: Define the direction by an axis of the view window.
   • Bearing and inclination: Define the direction by a bearing and inclination angles.
   • Action plane axis: Define the direction by an axis of the action plane.

6. Fill in the remaining fields appropriate to the type of projection selected (if required).

7. Click OK or Apply to complete the process.
