About the Attached Flat Wall User Interface
The
Flat user interface consists of commands, tabs, and shortcut menus. To access the
Flat tab, click
Model >
Flat.
Use the following configuration options to control the default values and behavior of selected tool settings:
• smt_drive_tools_by_parameters—Uses parameter values as the default values of selected tool settings and to automatically update features when parameter values change.
• smt_drive_bend_by_parameters—Uses parameter values to control the default value of bend angle and bend dimension location settings and to automatically update features when parameter values change.
|  If you want to enable smt_drive_bend_by_parameters, you must also set smt_drive_tools_by_parameters to yes. |
In the following descriptions, [<Parameter Value>] indicates that tool settings are controlled by parameters.
Commands
• Shape list—Lists wall shapes:
◦ Standard wall shapes:
▪ Rectangle—Rectangular wall
▪ Trapezoid—Trapezoidal wall
▪ L—L-shaped wall
▪ T—T-shaped wall
◦ User Defined—Select to create a new wall shape using the Shape tab.
◦ Predefined wall shapes—Saved wall sketches appear on the list when they have been accessed during the current session.
| You can use the Flat_shape_sketches_directory configuration option to specify the directory path to your library of predefined flat walls shapes to appear on the list. |
• 
Wall Angle list—Lists predefined values, user-defined values, a flat wall option, and [<Parameter Value>] for the wall attachment angle.
—Flips the angle direction to the other side of the attachment wall.
| • [<Parameter Value>] uses an angle set by the SMT_DFLT_BEND_ANGLE parameter. • The angle between the attachment edge and surface cannot exceed 180 degrees. When you need a larger angle, use the opposite side of the sheet metal as the attachment edge. |
• —Flips the
material thickness direction.
• 
—Adds a bend to the attachment edge according to a specified value. Default values are as follows:
◦ Thickness—Uses a radius equal to the thickness of the sheet metal wall.
◦ 2.0 * Thickness—Uses a radius equal to twice the thickness of the sheet metal wall.
◦ [<Parameter Value>]—Uses a radius as set by the
SMT_DFLT_BEND_RADIUS parameter.
• Dimension Location buttons:
◦ 
—Dimensions the radius according to the outside surface of the wall.
◦ 
—Dimensions the radius according to the inside surface of the wall.
◦ 
—Dimensions the radius as set by the
SMT_DFLT_RADIUS_SIDE parameter.
Tabs
• Placement—Displays the selected edge type in the collector.
• Shape—Displays the following options:
◦ Sketch—Opens the sketch in Sketcher for editing.
| To change sketch references or orientation or both, click Sketch > Sketch Setup in Sketcher. |
◦ Open—Opens the Open dialog box to select a saved .sec file.
◦ Save As—Opens the Save a Copy dialog box, to save the wall sketch as an .sec file in the specified directory.
◦ Shape attachment—Determines how the wall is dimensioned:
▪ Height dimension includes thickness—Includes sheet metal thickness when calculating wall height.
▪ Height dimension does not include thickness—Does not include sheet metal thickness when calculating wall height.
▪ Sketch window—Displays a window to preview and edit the sketch dimensions.
• Offset—Sets the segment section in relation to the attachment edge.
◦ Click the Offset segment with respect to attachment edge check box to activate the following options:
◦ Type—Sets the type of offset.
▪ Add to part edge—Adds the segment to the attachment edge without trimming the length of the attachment segment.
▪ Automatic—Offsets the new segment, so that it does not go above the original height of the attachment segment.
▪ By value—Offsets the segment by a specified value. Set the following options:
Measure to—Set the way the offset is measured. Use Bend surface to measure the offset from the attachment edge to the bend surface. Use Origin to measure the offset from the attachment edge to the bend origin.
Offset—Type an offset value in the box or choose from a list of previously used values. Use a positive value to add to the attachment segment by the specified value. Use a negative value to trim the attachment segment by the specified value.
• Relief—Sets the type of wall relief.
◦ Click the Define each side separately check box to set separately the relief for each wall end.
▪ Side 1—Sets the relief for the start point of the attachment edge.
▪ Side 2—Sets the relief for the endpoint of the attachment edge.
◦ Type—Lists the types of relief available. Depending on the type of relief, other selections become available:
▪ No Relief—Adds no relief.
▪ Rip
—Adds a rip relief.
▪ Stretch—Adds a stretch relief.
▪ Rectangular—Adds a rectangular relief.
▪ Obround—Adds an obround relief.
▪ [<Parameter Value>]—Adds a relief whose type is controlled by the
SMT_DFLT_BEND_REL_TYPE parameter
When the Bend Relief type is set to Rectangular or Obround, you can set values for the following options:
▪ Relief depth:
Blind—Creates a the bend reliefs with a depth set in the box below.
Up to Bend—Creates the bend reliefs up to the bend line.
Tangent to Bend—Creates the bend reliefs tangent to the bend.
[<Parameter Value>]—Uses the SMT_DFLT_BEND_REL_DEPTH_TYPE parameter value.
▪ Relief length:
Blind—Creates the bend reliefs with a length of the specified value.
To Next—Creates the bend reliefs with a length to the next surface.
Through All—Creates the bend reliefs through all surfaces.
[<Parameter Value>]—Uses the SMT_DFLT_BEND_REL_LENGTH_TYPE parameter value.
▪ Relief width:
Thickness—Use a default width that is equal to the thickness of the sheet metal wall.
Thickness * 2—Use a default width that is twice the thickness of the sheet metal wall.
[<Parameter Value>]—Uses the SMT_DFLT_BEND_REL_WIDTH parameter value.
Type a value—Use the absolute value that you type in the box.
• Bend Allowance
Use this tab to set a feature-specific bend allowance to calculate the developed length of the bend.
◦ Use part settings—Uses the developed length calculation set for the part.
◦ Use feature settings—Uses the developed length calculation defined below.
▪ By K factor—Calculates the developed length according to the K factor. To change the value for K factor, type a new factor value or select a value from the list.
▪ By Y factor—Calculates the developed length according to the Y factor. To change the value for Y factor, type a new factor value or select a value from the list.
▪ By bend table—Calculates the developed length using a bend table. To choose a different bend table, select one from the list.
• Properties—Displays the feature information:
◦ Name—Shows a default name for the wall.
◦ 
—Shows feature information in a browser.
