Creating a Core Sampling

• define a core sampling point (Location/Direction),
• select the elements on which you will perform the core sampling (Filters),
• click Apply to visualize the result in the dialog box,
• click OK to save the result in the CATPart,
• export the result from the specification tree, if necessary.

Available in DMU Composites Review (CPR), in a CATProduct context.
The core sampling is performed on the whole CATProduct or on a selection of CATParts under the CATProduct.
However the core sampling result will not be stored in the CATProduct: OK is disabled.
You will:

• define a core sampling point (Location/Direction),
• select the elements on which you will perform the core sampling (Filters),
• click Apply to visualize the result in the dialog box,
• export the result from the dialog box, if necessary,
• click Cancel to exit the dialog box without saving the result in the CATProduct.

You can perform several core samplings with different core sampling points.

• Part_01.CATPart from the samples\Composites directory if you are working in Composites Design (CPD) and Composites Engineering Design (CPE),
• CPD_01.CATProduct from the samples\Composites directory if you are working in DMU Composites Review (CPR).

1. Click Core Sampling .
   The Core Sampling dialog box is displayed:
   In Composites Design (CPD) and Composites Engineering Design (CPE):
   
   In DMU Composites Review (CPR):
   
   

2. Define the Location/Direction of the core sampling by a core sampling point:
   

   you can either select an existing point: click click Entity and select the entity where you want to indicate a core sampling point. Then pick this entity again where you want the core sampling point to be. This entity can be: a plies group, a ply, a cut-piece, a tape, a surface.
   	The core sampling point must lie on the surface: With the option Point, you must select a point that lies on the surface. With the option Entity, if the indicated point does not lie on the surface, its projection on the surface is used. In both cases, a core sample feature will be created. However if you indicate a point, this point will not be modified if you modify the surface (only its 3D coordinates are stored, not its position on the surface).
   	In Composites Design (CPD) and Composites Engineering Design (CPE), the option Point offers you the possibility to create a point with a contextual menu. In DMU Composites Review (CPR), this contextual menu is not available. The core sampling point must already exist.

3. If necessary, you can modify the location/direction:

   using the manipulators that appear in the 3D geometry. You can drag them both sides. using the direction arrow: it shows you in which direction the plies will be taken into account. Click the arrow in the graphic area, or click Invert Direction in the dialog box to invert the direction.

4. Filters lets you define the selection of entities on which the core sampling will be performed.
   

   In Composites Design (CPD) and Composites Engineering Design (CPE): by default, the whole CATPart is selected. click to select plies groups. if you select an element under a plies group, the plies group is automatically selected. In DMU Composites Review (CPR): by default, the whole CATProduct is selected. click to select CATParts under the CATProduct. if you select an element under a CATPart, the CATPart is automatically selected. If there are any: select the Take cut-pieces into account check-box to take them into account. select the Include non structural plies check box to take them into account.

5. Click Apply to analyze all the plies on each side of the point.
   The dialog box is updated and the number of plies as well as the total thickness is displayed
   (we have resized the dialog box):
   In Composites Design (CPD) and Composites Engineering Design (CPE), the table looks like this:
   
   In DMU Composites Review (CPR), the table has one more column, for the Part ID:
   
   Note that:

   the plies appear in their real order, if any, cut-pieces that intersect each other are displayed in the list.

6. In DMU Composites Review (CPR), you can export the result of the core sampling:
   
   Click ... to enter the path and the name of the export file.
   Select the Open file after creation check box if you want to do so.
   Select the option corresponding to the format required for the export file.
   Click Export.
   Ply Table:
   
   The plies with multiple intersections, if any, are listed at the end,
   the number of multiple intersections is given for each ply concerned.
   Core Sample:
   
   The plies are listed in the order they have been processed, which makes the multiple intersections more visible, if any.
   Click Cancel to exit the dialog box.
   
   In the Composites Design (CPD) and Composites Engineering Design (CPE):
   Click OK to create the core sample and exit the dialog box.
   
   

7. In Composites Design (CPD) and Composites Engineering Design (CPE), once the core sampling is created, you can export it from the specification tree:
   
   If the Core samples node contains several Core samples elements, they are all listed in the xls file.
   The Core Samples dialog box is displayed:
   
   Click ... to enter the path and the name of the export file.
   Select the Open file after creation check box if you want to do so.
   Select the option corresponding to the format required for the export file.
   Click OK.
   Ply Table:
   
   All plies are listed by their name.
   The plies with multiple intersections, if any, are listed at the end,
   the number of multiple intersections is given for each ply concerned.
   Core Sample:
   
   The plies are listed in the order they have been processed, which makes the multiple intersections more visible, if any.
