Generate Bridges

Imported or manually created street networks often lack elevation data, which is necessary for the 3D display of crossing streets. The Generate Bridges tool can automatically create such data. It can by executed using the main menu menu:Graph→Generate Bridges.... It operates either on the current street selection or on all streets when nothing is selected.

 

Note that the wider street is kept naturally at it's original level, while the thinner street is raised. Also, please note that new street nodes are inserted at the correct distances from the crossing point, defined by the maximal defined slope. The vertical tangent components are automatically adjusted.
