Reducing Polygons in Rx Shapefiles
Displays, such as Precision Planting's Gen 3 and Kinze's Blue Vantage, will only accept a certain number of polygons. Here is how to reduce the number of polygons in SMS.
- Import your shapefiles into SMS as Planting Prescriptions (if you bring these in as "Generic" and change them when you save the fields, this WILL NOT WORK!)
