Evaluate > Cross section

Creates cross section geometry on selected surfaces or meshes.

Options

Section Type

Axis Aligned: The cross sections are perpendicular to the X, Y, and Z axes and are evenly spaced.

Picked Reference: The cross sections are created at the intersection between the geometry and selected section data or construction planes.

Radial: The cross-sections are created based on a driving curve you specify. Points, equally spaced by arc length, are placed on the curve to correspond to a given number of sections. A plane is then defined perpendicular to the curve's tangent at each of these points. The cross-sections are created where the planes intersect the geometry.

The driving curve can be a free curve, a curve-on-surface, or a surface edge or isoparm. More than one driving curve can be selected if all curves are tangent continuous.

Construction History

Turn this option on to save the construction history of the cross sections. This way, the cross sections will update when you modify the underlying geometry.

Create Section Data

If this option is not checked, NURBS cross sections are created. If it is checked, the NURBS are rebuilt as section data, according to the Tolerance value.

Tolerance

Fitting tolerance used to rebuild NURBS curves as section data.

> Axis Aligned Options

These options appear only when Section Type is Axis Aligned.

> X/Y/Z

Turn on or off to view various combinations of cross sections perpendicular to the X, Y and Z axes.

Auto Range

If this option is checked, we use the bounding box of the picked objects to determine where to compute the cross sections, independently of the object's position in space.

Start/End

These options only appears when Auto Range is off.

Enter the 3D coordinates of two corners of a bounding box. The cross sections will be calculated for the region of the selected object(s) that intersect this box.

If Start equals End, a single cross section line is created.

Step

The spacing between cross section lines along the X, Y, and Z axes.

> Radial Options

These options appear only when Section Type is Radial.

Number of Planes

Number of planes to define along the driving curve(s). The cross-sections are created where the planes intersect the geometry.

Chain Select

If this option is checked, selecting a driving curve also selects all other curves that are tangent continuous with it.
