All thickened sheet metal features have two distinct sides: The wall will be extruded This edge will share the vertex where you put the datum point. It can be called up in the drawing module just as a part would be.

A new datum will be created on the fly which passes through this datum point and is normal to the attachment edge. Note that the sketched thin profile won't show up as green until after the feature operation is finished. In this case, it will be sgeet inside edge of the wall. This edge will share the vertex where you put the datum point. This wall can either be a flat pattern, or an extrusion of a thin profile.
First cut two holes in the part. The radius you sketch has to be tangent to the existing surface.
The instance is now created showing your part in the flattened state. Now go back and erase the first straight line you drew and align the yutorial arc to both the vertical and horizontal edges of the existing surface.
Draw the profile as a three-sided, open loop. First you will have to unbend one of the bends in the sheet metal. The amount of meal that has to be added to the flat pattern for each bend is controlled by a number of parameters, including: Now sketch the thin profile.
Because the extrusion only extends along part of an edge, a datum point is needed to define a starting point along the attachment edge. Finally, radius the corners seen in Figure To help guarantee this, you should seet a straight line over top the existing edge and then draw a tangent arc. This can be added in as a general view pictorial in the upper right corner.
Again, the no radius option is used because you will draw in the radius rather than letting the system create it for you. The difference is that it will attach to an existing edge and only extend part way along the edge.
Use the same process to create the feature seen in Figure 4. The difference in the radii is defined by the thickness of the material we are using, 3. These holes can be centered on a common datum axis.
Pro/ENGINEER - Sheet Metal
Woldfire thickened sheet metal features have two distinct sides: Sketch the green side as seen in Figure 1a. Now cutting and other material removal operations are used to shape the final part. Repeat the process again to create a new wall on the end of the wall you just created. Place a datum point, PNT0as seen in Figure 3b, using:. Add a view and enter the name of the sheet metal part. Again, you will have to start by creating a datum point on the other end of the edge.
TUTORIAL: Pro/E Sheetmetal – Unattached Flat Wall
The last option indicates that the part is currently completely bent. Because it is a thin featureyou will only define one side of the sheet metal that will eventually be thickened to the specified thickness of the metal.
When you sketch a thin feature, you sketch the green side which is then thickened to form the white side.
Select the horizontal green edge closest to you as the attachment edge. The round feature is a solidrather than sheet metal, feature. One more cut is needed to chamfer an edge. The next feature will be an extrusion like the base feature. The result might look like Figure
