Overview on Region Analysis

The Region Analysis command enables you to analyze a mold part. This analysis provides the base for alternate method for creating the core and cavity in the MoldDesign module. You can identify and classify the faces as regions of the mold part as core, cavity or slider. This process minimizes the effort in identifying the core and cavity faces and gives you more control on the mold part. The faces can be converted to skin using this command. The skins will be used in creating the core and cavity using the Region based option in the Split Mold command. The following are the functionalities of the Region Analysis options in the selection list.

Direction

The direction is one of the most important criteria for analysis. The direction of the extraction of the mold part will determine the result of the analysis. You can have multiple region analysis by selecting different extraction directions.

On starting the Region Analysis command, the mold part is selected for the Solid selector in the selection list. Under the Directions node, you can enter a name in the Directions text box, else the application itself names each analysis as Direction 1, Direction 2 etc. The analysis is based on the selection of the extraction direction. Each direction analysis can be named as per your requirement using the Directions text box. Then select the extraction direction using the Direction drop-down list.

Once the analysis of the mold part has been done by selecting a specific direction, then two buttons are available for selection.

	New Direction	Each click on the button enables you to select another direction of extraction, based on which the analysis will be computed.
	Delete Direction	Each click on the button enables you to delete the analysis of the direction selected in the corresponding drop-down list.

Using the New Direction button, you can analyze the mold part based on a new direction of extraction. This multiple direction analysis can be done in a single working session of the command.
