Creating a split surface

You can create split surfaces using two methods:

• offsetting a single split line
• fitting an existing surface to split lines

Creating a split surface by offsetting a single split line

The split surface is created by selecting a composite curve as the split line. This split line is then offset by a specified distance and along a specified angle. One side of the split surface is the split line and the other side is the offset of the split line.

1. Click Surface tab > Manufacture panel > Split.
2. Select the Composite curve option from the Split Surface dialog:

   

3. Select the composite curve which defines the split line:

   

4. Complete the dialog.

Creating a split surface by fitting a surface to split lines

The split surface is created by modifying an existing surface to fit split lines. The split surfaces:

• preserve the outline of the surface and the tangency at the outline.
• fit the wireframe at directions parallel to the principal plane.

PowerShape also attempts to trim off the surface inside the wireframe.

1. Click Surface tab > Manufacture panel > Split.
2. Select the Surface option from the Split Surface dialog:

   

3. Select the surface:

   

4. Select the Split lines option from the Split Surface dialog:

   

5. Select the section of wireframe along which you want to split the surface:

   

6. Click Preview to see the result.

   PowerShape generates the split surfaces and attempts to trim off the surface inside of the wireframe:

   

7. Change the selection if necessary.
8. Click OK when you have the required results.

1. A split surface is a Power Surface and is edited accordingly. For further details, see Editing Power Surfaces.
