Location, Direction and Axis Specification

• Specifying a Location
• Specifying a Location on a Curve
• Specifying a Direction
• Specifying an Axis
• Specifying a Plane
• Drawing a Location, Direction, or Axis

Many commands require that a location or a direction be specified. Although entering the three floating point numbers required to uniquely define a vector is perfectly acceptable, it may be more convenient to specify the direction or location with respect to existing entities in the model.

For example, the following commands might be used for creating straight curves using location and direction specification described here:

Create Curve [From] Location {options} Location {options}

Create Curve [From] Location {options} Direction {options} Length <val>
