- Using the Command Line
- List of Commands Ordered by Functionality
  The next table represents an exhaustive list of the commands supported in newFASANT. These commands are ordered by the function they perform.
- Command Reference
  - analyzeCurvature
    This option is useful to identify the curves and surfaces in the geometry that describe large curvatures. Given a desired angle as reference (in degrees), if some of the selected objects describe curvatures bigger than the reference angle the points are generated where the curves has varied their direction every angular step. The detected points may be only visualized or also added to the geometry.
  - analyzeEdges
    This tool allows the user to detect the edges in the geometry. The edges may be only visualized or also added to the geometry.
  - analyzeNakedBorders
    This tool allows the user to detect the naked borders (borders of the surfaces that are not in contact with other ones) in the geometry. The borders may be only visualized or also added to the geometry.
  - angle
    This tool allows the user to calculate the angle (in degrees) between two given vectors. Vectors are specified by an initial point and an end point.
  - arc
    This command allows the user to draw a circumference arc specifying its central point, radius, initial and final angles (in degrees), in this order.
  - area
    This command returns the total area of the selected surfaces.

    This command computes the resulting surfaces of subtracting the second object to the first one (A minus B operation), that is, the regions of the first object that are not contained in the second object.
  - booleanInside
    This command select the surfaces of the first object that are contained in the second one (A inside B operation).
  - booleanIntersection
    This command creates an object with the regions of the two selected objects that are included in both of them (A AND B operation). Note that the original objects used for the operation will be deleted.
