Radial sections

images/download/attachments/122259580/CmdRadialSections.svg

This command computes a set of planar sections around an axis. Set of sections are displayed as a single entity, but you can access to each individual section using the command Ungroup Polyline.

Requirements

Select all the mesh(es) on which you want to calculate sections and launch the command.


  1. Enter the direction of the radial section axis.

  2. Enter the origin of this axis.

  3. Range : choose where the sections are calculated:

    • Regular: with a regular step, for example one section each 45°

      • All over: all over the object

      • Custom: only between two angle values

      • Pass through: force the section to pass through a given angle or a given point

    • List of angles: pick points or enter angle values to choose where to calculate sections.

  4. You can also select the option Compute parallels to obtain quadrangular contours.


Technical information

Sections on an inspected mesh

If the sections are computed on the inspected mesh (considered as well as the reference or measure), the sections will keep the inspection values of the mesh. It means that the hair diagram will not be, in most cases, in the plane of the section. It depends on the type of inspection (2D or 3D).

Restriction: when a mesh was colored as the measure with a cloud as reference, this capability is not available.

Example of a hair diagram in 3D on a planar section:

If you want to have a hair diagram on the plane of the section:

  • Do an inspection in the direction of the plane and then do a section with this plane.

  • Do a section in the plane on both entities (reference and measure) and then do an inspection of this polyline/set of polylines.
