The Create Section Curves option creates new curves at the intersection of selected surfaces with single or multiple planes.
- Surfaces
Select the surfaces.
- Plane Setup
Specify the planes that intersect with the selected surfaces to create the new curves.
- Normal to XYZ Plane
Select the plane normal to the X, Y, or Z axis. The plane will pass through the origin (0, 0, 0).
- Start Point / Multiple
This option allows you to define a Start Point through which the plane must pass, and allows for multiple planes defined by an offset value.
- Delta Offset
To define multiple planes, a Start Point and End Point must be defined. The offset value is defined as a fraction of the distance between the Start and End points. Planes will pass through each offset point, as well as the Start and End points, resulting in multiple section curves. For example, if a Delta Offset value of 0.5 is entered, a plane will pass through the Start Point, the End Point, and the point halfway between the Start and End points.
- Normal to Three Points
Select 3 points to define a plane. The plane normal to this will be used in the creation of the new curves.
- Normal to Existing Curve
Select a curve. The number of sections that is entered will result in equally distributed planes normal to the selected curve at the local parameter. For example, if a curve that is a circle is selected, and 10 sections are specified, then 10 planes normal to the circle, at every 36 degrees, will be used to create the new curves.
