Contour

The Contour command creates a spaced series of planar curves and points resulting from the intersection of a defined cutting planes through objects.

Input
  • Curves, Surfaces, Polysurfaces, Extrusions, Meshes, SubDs

Steps

  1. Select objects for contour creation.

    2. Infinite Plane: Type IP for InfinitePlane options.

  2. Pick the base point.
    One of the contour planes will go through this point. The contour curves and points are created from the intersections of a series of invisible parallel planes cutting through the selected object.
  3. Pick a direction perpendicular to the contour planes.
    The contour planes will be generated in both directions from the base point and will be perpendicular to the picked direction.
  4. Specify the distance between contours and press Enter.
    This will create contour curves where the contour planes intersect the selected surfaces and polysurfaces and points where the contour planes intersect the selected curves.
Command-line options

AssignLayersBy
CurrentLayer

Creates the output curves and points on the current layer.

InputObject

Creates the output curves and points on the same layer as the input objects.

GroupObjectsByContourPlane

Specifies whether or not contour on the same contour plane will be grouped.

JoinCurves
ByPolysurface

Curves in the same contour plane created from a polysurface will be joined.

ByContourPlane

All curves in the same contour plane will be joined.

None

No curve joining.

Range

Specifies limits for the contours.

Steps

  1. Select objects for contour creation.
  2. Pick the start for the contour curves and points.
  3. Pick the end of the contour range perpendicular to the contour planes.
    The range line determines the direction for the contours curves.
    The contour planes will be perpendicular to this direction, generated from the base point to the end point.
  4. Specify the distance between contours and press Enter.
    Contour curves are created where the contour planes intersect the objects.

SubCrv

Type subcrv to select part of a curve as input.

Section

The Section command creates a planar curve or points resulting from the intersection of a defined cutting plane through objects.

Input
  • Curves, Surfaces, Polysurfaces, Extrusions, Meshes, SubDs

Steps

  1. Select objects.
  2. Pick the start of the section plane.

    3. Infinite Plane: Type IP for InfinitePlane options.

  3. Pick the end of the section.
    Section curves and points are created by intersecting the selected objects with the section plane, which is perpendicular to the construction plane.
  4. Press Enter when you finish creating sections.

Curves in the same section plane created from a polysurface will be joined.

ExtendSection

Specifies whether or not the section curves will automatically be created for all selected objects as though the drawn section plane extended through them.
