To Create a Boundary Blend Wall
1. Click > 
Boundary Blend. The Boundary Blend tab opens.
Boundary Blend. The Boundary Blend tab opens.2. For the first wall in your design, type a value for the wall thickness or accept the default value.
3. Select a curve, wall edge, datum point, or end of curve or edge as a reference entity of the wall boundary for the first and second directions.
4. To set sheetmetal-specific options, click Options. The Options tab opens. Perform any of the following operations:
◦ Click Add bends on sharp edges to round sharp edges when the sketch includes nontangent geometry. Set the value of the radius and the location for dimensioning the radius.
◦ To set options for merging an additional wall to the model, set the options below:
▪ Select Merge to model to merge the wall to an existing wall in the design. You now have the option to keep the edges of merged geometry and edges of bend surfaces. This option is not available for a first wall.
▪ Select Do not merge to model to keep the new geometry as a distinct piece. You now have the option to flip the driving surface of the sheet metal.
5. To set feature-specific bend allowance and calculate the developed length using a different method from that of the part, perform the following operations:
a. Click Bend Allowance. The Bend Allowance tab opens.
b. Click Use feature settings.
c. Perform one of the following operations:
▪ Click By K factor or By Y factor and type a new factor value or select one from the list.
▪ To use a bend table to calculate developed length for arcs, click By bend table. Use the default table, select a new one from the list, or click Browse to browse to a different table.
 | Only bend tables copied to the part are available. |
