Selecting Geometric Elements on CATIA Version 4 Models

This task shows you how to display a CATIA Version 4 model workspace and select its geometric elements in CATIA Version 5.
Open the document XWINGS.model.

  1. Above the geometry area where the Version 4 model is displayed, click the workspace tab you wish to display (the FUSELAGE workspace in the model shown below, for example), the tab selected then "rises" relative to the other tabs.

  2. If you then wish to select a geometric element, expand the specification tree by clicking on the FUSELAGE item and then on one of the items with a plus sign, *SET5, for example. The specification tree will then look like this:

A set is made up of subsets each containing lines, curves, surfaces, solids, dittos, etc. In the specification tree shown above these are easily identifiable (LN, CRV, SUR, etc.). A subset can be selected just like any other item for copy/paste, show/no-show operations, etc.
However, you can of course select one or more of the lines, curves, solids, etc. contained in the subsets.

  1. Click on the plus sign of the DIT subset and select the contents, *DIT13.
    Notice that the corresponding part of the model in the geometry area is highlighted as shown below:

You can of course select an element by clicking on it in the geometry area.

Note that if you select a Ditto (DIT) in the Specification Tree, you select all the components within the Ditto. For instance, if you hide a Ditto by transferring it to the No Show space, all the objects under Ditto will no longer be displayed in the Geometry area.

  1. Click on the central part of the fuselage (not on the blue component shown above). The corresponding solid is highlighted in the specification tree:
  As you can see above, in the specification tree, double-clicking boxes with a plus sign shows the component elements of that particular workspace or set. Clicking the minus sign hides the elements contained in the workspace or set.
