Creating a pocket consists in extruding a profile and removing the material resulting from the extrusion. You could actually create pockets for each part in the Part Design workbench, but the Assembly Pocket command available in Assembly Design workbench creates pockets more rapidly and more productively: the command creates a pocket on several parts in only one interaction. | |
This task shows you how to create a pocket by removing material from two parts. | |
Open the AssemblyHole.CATProduct document and sketch a rectangle on the purple face. | |
|
|
You can use profiles sketched in the Sketcher workbench, sub-elements of sketches or planar geometrical elements created in the Generative Shape Design workbench. |
|
The Assembly Features Definition dialog box appears. |
|
The dialog box that appears displays the names as well as the paths of the parts that may be affected by the extrusion. |
|
The assembly feature's name appears in the Name field. If desired, you can edit this name. |
|
The frame Affected parts is exclusively reserved for the parts you wish to use. Purple Part is displayed in this frame. |
|
Note that the Pocket Definition dialog box is displayed. |
|
|
|
The other three buttons lets you move the names of the parts from one list to another too: |
|
|
|
|
|
You can define a specific depth for your pocket (using the Dimension and Depth entry fields) or set one of these options to define the pocket type: |
|
|
|
If you wish to use the Up to plane or Up to surface option, you can then define an offset between the limit plane (or surface) and the bottom of the pocket. |
|
The other options available are: |
|
|
|
Additional options appear if you click the More button. |
|
|
|
|
|
The pocket is created on both parts. |
|
A new entity 'Assembly features' appears in the specification tree. It contains the assembly pocket referred to as 'Assembly Pocket.1" and the affected parts. |
|
Moreover, this feature has generated a pocket in each part. An arrow symbol identifies these pockets in the tree, meaning that a link exists between Assembly Pocket.1and them. |
|
Editing an Assembly Pocket |
|
To edit an assembly hole, double-click Assembly Pocket.X entity then you can either: | |
|
|
If you need to cut the link between a generated pocket and Assembly Pocket.1, just use the Isolate contextual command. Obtain a 'traditional' pocket as if you have designed it in Part Design and you can edit it in Part Design. | |
Reusing Part Design Pockets |
|
To increase your productivity, you can create Assembly pockets from existing Part Design pockets, or more precisely by reusing the specifications you entered for designing Part Design pockets. To do so, just proceed as follows: | |
Before reusing Part Design pocket, note that:
|
|
|
|
|
|
|
|
The assembly pocket inherits the specifications as displayed in the Part Design Pocket Definition dialog box. You can edit these specifications at any time. Editing an Assembly feature created in this way does not affect the specifications used for the Part Design feature. |
|
Reusing Assembly Design Pockets |
|
The application also lets you reuse Assembly Pockets' specifications to accelerate the design process. In this case, you just need to select the existing assembly pocket, click the Assembly pocket icon and then select a face. Only the Assembly Features Definition dialog box appears to let you determine the parts to dig. |
