Associativity of Prismatic Machining Area

task target This task illustrates the associativity of prismatic machining areas.

A prismatic machining area in the manufacturing view has associated geometry in the part document. Typical geometry could be:

  • Top element
  • Bottom element
  • Boundary profile
  • Other Prismatic machining area parameters such as minimum corner radius.

If the geometry is modified in the part document, then corresponding parameters and RSUR information for prismatic machining area is updated in manufacturing view to reflect correct values.

scenario 1. Select File > Open then select the PrismaticMachining.CATPart document.
2. Select the Global Feature Recognition icon and create a Complex Pocket.

  3. Select the Manufacturing View icon in the Machining Features toolbar. Right-click the Manufacturing View object and select the Sort by Machining Features contextual command.

  4. Double click the created Prismatic machining area in the tree. A dialog box appears showing the characteristics of the feature.

  5. Right click the green flank area of the pocket in the sensitive icon and select the Analyze contextual command. The Geometry Analyser appears showing that the status of each of the guide elements making up the pocket is Up to date.

Analyze the bottom element in the same way to check that its status is also Up to date.

  6. Modify the geometry of the pocket (for example by reducing the pocket depth).

  7. In the Manufacturing View, analyze the new guide elements and bottom of the pockets.

Their status is Up to date, showing the associative nature of the prismatic machining area.

Some geometry modifications to a part document can change the feature type. For example:
  • the depth of complex pocket can be changed so that it becomes complex cutout
  • the boundary profile of a complex pocket can be modified in such a way that  it becomes a complex step, blind slot or through slot.

Such changes are not associative.
