Creating Section Boxes

This task explains how to create section boxes. To do so, you must first create the master section plane.

Insert the following cgr files: ATOMIZER.cgr, BODY1.cgr, BODY2.cgr, LOCK.cgr, NOZZLE1.cgr, NOZZLE2.cgr, REGULATION_COMMAND.cgr, REGULATOR.cgr, TRIGGER.cgr and VALVE.cgr.

They are to be found in the online documentation filetree in the common functionalities sample folder cfysm/samples.

Before you begin

When dealing with CATProducts containing a large amount of sections, for gain performances purposes, read carefully the Customization recommendations (follow the described procedure).

  1. Select Insert > Sectioning from the menu bar, or click Sectioning in the DMU Space Analysis toolbar to generate a section plane.

    The section plane is automatically created. If no selection is made before entering the command, the plane sections all products. If products are selected, the plane sections selected products.

    This plane is the master plane and controls all operations on the section box.

    The Sectioning Definition dialog box is displayed. This dialog box contains a wide variety of tools letting you position, move and rotate the master plane. For more information, see Positioning Planes with respect to a Geometrical Target, and Positioning Planes Using the Edit Position Command.

    A Section result window appears alongside the document window. It displays a front view of the generated section and is by default, locked in a 2D view.

     

  2. In the Definition tab, click Section Box drop-down to create a section box:

    A sectioning box is created. The contours of box planes are red. The Section viewer is automatically updated.

  3. Adjust the thickness of the section box: position the cursor over one of the slave box plane edges, click then drag to translate the plane in the desired direction.

    Notes:

    • As you move the cursor over box edges, the cursor changes appearance and arrows identifying the directions along which box thickness is defined appear. Box thickness is also indicated as you drag. 

    • You can also re-size the box by clicking and dragging one of the box sides. Arrows likewise appear to help you.

    • Use Geometrical Target in the Positioning tab to snap boxes to planes.

  4. Click OK when done.
    Note: When sectioning solids which are intersecting, the result displayed is not correct. The intersection between the two solids is not retrieved nor displayed properly, i.e. an empty cavity appears instead.
    Refer to About Sectioning solids which are intersecting
    You can create boxes around the various areas of your product and then, using the Volume Cut command isolate the area on which you want to work.
