Sheet metal Cut Features
A sheet metal cut removes material from the walls it encounters.
In Creo TOOLKIT, a sheet metal cut feature shares the same element tree as the basic extrude feature or the solidify feature or the thicken feature. The element tree should include some of the following sheet metal cut-specific elements to generate a sheet metal cut feature:
• PRO_E_IS_SMT_CUT—If true this feature is a sheet metal cut, otherwise it is a solid cut. It is applicable only in sheet metal parts.
• PRO_E_SMT_CUT_NORMAL_DIR—This element defines the surface to which the section projection will be normal. The projection normal specifies the side of the sheemetal wall from which the sketched curve splits the wall. The values for this element are as follows:
◦ PRO_SMT_CUT_DRVSIDE_GREEN—Specifies the normal to the driven surface. This is a direction from the green side to the white side of the sheet metal wall. This is the default value.
◦ PRO_SMT_CUT_DRVSIDE_WHITE—Specifies the normal to the offset surface. This is a direction from the white side to the green side of the sheet metal wall.
For details on the basic Extrude feature, see the section
The Element Tree for Extruded Features.
For details on the basic Solidify feature, see the section
Solidify Feature.
For details on the basic Thicken feature, see the section
Thicken Feature.
The extrude feature has additional optional element PRO_E_SMT_PUNCH_TOOL_DATA. This compound element defines sheet metal cut that is used to cut and relieve sheet metal walls. It is used in sheet metal manufacturing. It is applicable to sheet metal cuts, made by the Punch UDF. It defines the parameters related to the punch feature.
The compound element PRO_E_SMT_PUNCH_TOOL_DATA contains the following elements:
• PRO_E_SMT_PUNCH_TOOL_ATTR—Specifies the symmetry flag for the Manufacturing UDF Punch Tool. The valid values for this element are:
◦ PRO_PUNCH_TOOL_ATTR_SYM_NONE—Specifies that the tool is not symmetric about any axis.
◦ PRO_PUNCH_TOOL_ATTR_SYM_X—Specifies that the tool is symmetrical about the X-axis of the coordinate system
◦ PRO_PUNCH_TOOL_ATTR_SYM_Y—Specifies that the tool is symmetrical about the Y-axis of the coordinate system.
◦ PRO_PUNCH_TOOL_ATTR_SYM_XY—Specifies that the tool is symmetrical about both the X and Y-axis of the coordinate system.
• PRO_E_SMT_PUNCH_TOOL_NAME—Specifies the name of the Manufacturing UDF punch tool used.
For sheet metal cuts and punches, you can specify if the punch axis point must be created. A punch axis point is a reference point that moves with a feature during both, the unbend and bend back operations. In the element PRO_E_SMT_PUNCH_AXIS_PNT, specify PRO_B_TRUE to create the punch axis point in the sheet metal feature.
