Introduction

When creating geometry that will be subdivided, it is often necessary to add supporting edge loops around the edges that you want to keep sharp. As you continue to work on the mesh, you may want to tighten or relax these supporting edges, and to reposition them precisely. PowerSlide makes this easy and intuitive.

Moving one edge loop

1. Select an edge loop. This is the primary loop.
   
2. Select an adjacent edge loop.
3. Go in to PowerSlide.
4. Move the mouse pointer left or right to adjust the offset of the adjacent loop, or type an exact distance.

Moving two supporting loops

1. Select an edge loop.
   
2. Go in to PowerSlide.
3. PowerSlide will automatically find both adjacent supporting loops.
4. Move the mouse pointer left or right to adjust the offset of the adjacent loop, or type an exact distance.

Selecting awkward loops

If an edge loop is awkward to select, such as around the face of a cube, then let PowerSlide do it for you:

1. Select any part of the control loop. This can be a single edge.
   
2. Select any adjacent edges on the loop you want to move.
3. Go in to PowerSlide.
4. Press TAB. PowerSlide will find and select both loops.
5. Move the mouse pointer left or right to adjust the offset of the adjacent loop, or type an exact distance.

You can always make multiple selections, and PowerSlide will adjust them all at the same time. This can include a mix of selections, such as three pairs of edge loops and two single loops.

Moving vertices

1. Select one vertex. This is the control vertex.
   
2. Select another vertex. This vertex doesn't need to be directly connected to the first one, it can be anywhere on the mesh.
3. Go in to PowerSlide.
4. Move the mouse pointer left or right to adjust the offset of the second vertex, or type an exact distance.

You can select multiple vertex pairs and adjust them all at the same time.
