Abstract: The disclosure relates to methods and related systems for precision crop modeling and management using the same. Precision crop modeling and management can be incorporated into various methods for growing plants such as crop plants and various methods for managing the growth of such plants in a particular field. The methods generally utilize in-season information relating to weather conditions actually experienced by the field to prepare mid-season, updated crop management plans. A crop management plan is determined using a crop model incorporating a variety of inputs and plant-specific material and energy balances to specify one or more grower-controlled management parameters. An updated plan for a given field can be followed by a grower to increase crop yield and/or optimize one or more other crop or field parameters.

Abstract: In most of today's computer aided design (CAD), there are many definitive relationship between how components used in a CAD design relate to other components and feature in the same design. These relationships include sizing (a component is sized based upon another component), placement and orientation (a component is position and orientated based upon another component or feature). In addition, certain components can only be used with other specific components within the same design. Various attributes are placed on the CAD components and features that relate to each other that will be used to automatically size, place and orientate components, as well as make sure the component is valid to be used within the design intent. This saves designers considerable amount of design time as well as ensuring accurate component to component relationship as used in their design.
