Bridge

Options

Bridge

The Bridge tool works in all three modes (point, edge and polygon). A selection is required in polygon mode.

Bridge enables you to create connections between unconnected surfaces.

Point mode, edge mode, polygon mode and the results (bottom).

In point mode, you can create polygons by defining new polygon edges. To define a new polygon edge between two points, Drag & drop from one point to the other. A highlighted preview will appear to indicate where the new polygon will be created.

In edge mode, you can create a new polygon between two edges by dragging and dropping from one edge to the other. As with point mode, a highlighted preview will appear to indicate where the new polygon will be created.

In polygon mode, before you use the Bridge tool, you must first select the polygons that you want to connect. Then, using the Bridge tool, Drag & drop from one side to the other. A highlighted line will appear to assist you.

Figure 1

The original surfaces are connected together by four new surfaces. The original surfaces are deleted automatically, as necessary.

Not only does the Bridge tool enable you to connect surfaces, it also offers a quick way to create polygons from points. It is possible to create an entire, complex character using the Bridge tool. This method of creating polygons is especially useful when modeling with Subdivision Surfaces.

We will now use this technique to create a few polygons from scratch. The same technique applies to creating hundreds of polygons.

Using Esc to reset Bridge

If you click in the wrong place, you can quickly reset the Bridge tool by pressing the Esc key.

In the example above, note that you had to Drag & drop twice to create the first polygon, but only once to create the second polygon. This is because Cinema 4D assumes that you want the next polygon that you create to be connected to the one you have just created. This is ideal for quickly building a row or loop of polygons. However, if you don’t want the current polygon and next polygon to be connected to each other, press Esc to reset Bridge. You can then Drag & drop twice to create the next polygon in any position on the mesh.
