More about 2D-View Sections

In the specification tree, every group of the 2D-view section has four child nodes:

• The Cut elements node contains the result of an intersection operation performed on the group's geometries with the section plane, as well as a join operation performed on this result to unite non-connex wireframes.

  An additional Section join node is added under the Cut elements node. This node contains the result of a join operation performed on the point geometries resulting from an intersection operation performed on the group's geometries with the section plane.

• The Section transformation node represents the isometric transformation applied to the cut elements which are contained in the intersection plane in order to replicate and visualize these elements in the visualization plane.

  An additional Section transformation node is added under the Group node in the specification tree. This node contains the isometric transformation of the new section join feature.

• The Section join node is a join operation performed on the result of the section transformation and additional geometry added via the sketch edition in order to unite non-connex wireframes.

• The 2D-view thickness node contains the result of the optional corner and thickness operations performed on the elements of the section join.

These elements contained under the group node are not independently editable or removable. Double-clicking on them will open the 2D-View Section Definition dialog box.

You can insert your own GSD features in the 2D-view section under the 2D-view section node.

The visualization plane acts as a support plane for the wireframe elements added under the 2D-view section node.

This sub-topic provides information about positioning of the view plane elements.

The rectangular zone displayed on the plane chosen as the cutting plane is created when selecting the first element to be sectioned. The default size of this rectangle is chosen to loosely fit around all selected elements. Manipulators appear on the borders of this zone in the 3D area to modify its size. Changing its size restricts the portion of the section plane used to generate the wireframe elements contained in the Cut elements node.

As a consequence:

• These wireframe elements will no longer be the intersection of the whole cutting plane with the selected geometries but the intersection of the filled rectangle with the geometries.
• A connex intersection wireframe may become non-connex as a result of section plane delimitation.
• Some computed corners may be removed as a result of section plane delimitation.

If the selected cutting plane is not an infinite plane but a bounded planar surface, delimiting manipulators are still usable. The original intersecting element is the bounded surface selected as the cutting plane and rectangular delimiters have no influence. Once manipulators are moved, the intersecting element becomes the rectangular zone influenced by the manipulators, and the boundaries of the original surfaces selected as cutting plane have no influence.
