Instructions for use

The Update Edge Weight function is used to temporarily update the weights on the network arcs in memory.

When you Update Edge Weight, you need to be aware of the following issues:

• Update Edge Weight is only temporary and will not save the weight result to the field of Network Data. When the network layer is closed, the update result will be automatically cleared.
• When an arc segment is set as an obstacle edge, its weight is -1.
