Build Bridge

Use the Build Bridge tool to build a new surface by filling a region defined by 2-4 boundary edges. The new bridge surface can fill up gaps, holes and tunnels in a model imported from Iges.

To use the Build Bridge tool:

To be able to create a new Bridge surface, the following conditions must be met:

1. The edges of a 2 Edges' Bridge must not intersect on both sides (example 1).

2. The edges of a 3 Edges' Bridge must intersect on at least 2 junctions (example 2).

3. The edges of a 4 Edges' Bridge must intersect on all 4 junctions (example 3).

4. You must select the edges in a cross-like manner (example 4).

To Create A Bridge Surface

1. Select the Bridge tool. The model's display had changed to show the edges and vertices.

2. Select the edges to be filled with the bridge in a cross-like manner. The selected edges are highlighted.

   1. To deselect a selected edge Shift-select it.

   2. To deselect all selected edges click on Clear Lines  

3. Click the Space key () to build the bridge.

4. Right-Click to exit the tool.

Troubleshooting

If the bridge operation fails, you should check the following:

1. Try to select the edges in a different order.

2. Make sure the edges intersect (by zooming-in), meaning the vertices are at the same position.
