Video：<https://www.youtube.com/watch?v=l8xQOGeZpKM&feature=youtu.be>

Set the number of districts to draw and the number of plans to produce, enable shape compactness, and click Run.  **If you are using iRedistrict for Site**, the number of districts is the number of sites, which you cannot change.

iRedistrict produces multiple redistricting plans. There is no limitation on how many plans to create. However, the more plans to create, the longer time it takes. By default, this number is set to 30. This number can be changed.

&#x20;The threshold helps to reduce the population deviation. It is optional.&#x20;
