To Create a Swept Blend Wall
1. Click Sheetmetal > Walls > Swept Blend. The Swept Blend tab opens.
2. For a first wall, type a value for the wall thickness or accept the default value.
3. Click References. The References tab opens. Perform any of the following operations:
Define a trajectory and at least two sections for the swept blend.
4. Click Sections. The Sections tab opens. Perform any of the following operations:
Click Sketched Sections or Selected Sections, and then define Section 1. Click Sketch to open the Sketch tab.
If Sketched Sections is selected, then you need to define the Section Location.
If Selected Sections is selected, then you can click Details to open the Chain dialog box where you select Standard or Rule-based references.
If Rule-based is selected, then you can select Tangent, Partial loop, Complete loop, or All curves in feature. Click OK to exit.
Click Add Blend Vertex to add a blend vertex in the active section.
5. Click Tangency. The Tangency tab opens. Perform any of the following operations:
Click Start Section and then select Free, Tangent, or Normal from the Condition list.
Repeat the above for End Section.
6. 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.
7. 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.
