To take advantage of sectioning capabilities in a
CATAnalysis document, open the linked CATProduct before running the
The section plane is created parallel to absolute coordinates Y, Z. The center of the plane is located at the center of the bounding sphere around the products in the selection you defined.
A plane has limits and its own local axis system. The letters U, V and W represent the axes. The W-axis is the normal vector of the plane.
You can customize settings to locate the center and orient the normal vector of the plane as well as de-activate the default setting taking wireframe elements into account.
This is done using the Tools > Options..., Digital Mockup > DMU Space Analysis command (DMU Sectioning tab).
Sectioning is dynamic (moving the plane gives immediate results). You can manipulate the cutting plane in a variety of ways:
Results differ depending on the sag value used.
By default, this value is set to 0.2 mm.
3D XML format is supported, which means you can:
3D section cuts cut away the material from the cutting plane to expose the cavity within the product, beyond the slice or outside the box.
In DMU-P1, you cannot select products to be sectioned: the plane sections all products.
Creating Groups of Products
In DMU-P2, prior to creating your section plane, you can create a group containing the product(s) of interest using Group in the DMU Space Analysis toolbar or Insert > Group... in the menu bar.
Groups created are identified in the specification tree and can be selected from there for sectioning. Only one group per selection can be defined.
Creating section slices and section boxes are DMU-P2 functionalities.
For performance gain purposes, when dealing with CATProducts containing a large amount of sections, it is strongly recommended to apply the following procedure before opening your CATProduct documents:
