Geometry Commands

The set of geometry statements is given above. There are a number of ways in which the part geometry in APT could be specified. The part geometry is normally broken into a number of geometric elements that could be defined from the data given in a part drawing.

The Geometry Commands are as follow:

Point

ZSURF

• Using the Rectangular Coordinate Values
• By the Intersection of Two Lines
• By the Intersection of Line and Circle 
• By the Centre of a Circle
• By the Intersection of Two Circles  
• Polar Co-ordinates in a Co-ordinate Plane
• On a Circle at an Angle with X-axis

Line

• By Two Points Symbols or Rectangular Co-ordinates of Points
• By a Point and a Parallel Line
• By a Parallel Line at a Distance
• By a Point and a Perpendicular l Line
• By a Point and Angle made with a Line
• As One of the Co-ordinate Axis
• By a Point and a Tangential Circle
• Tangential to Two Circles 

Circle

• By the Centre and Radius 
• By its Center and a Point on the Circumference
• By Three Points on the Circumferences
• By the Centre and Tangential Line
• By its Radius and Two Points on the Circumference
• By the Centre and a Tangential Circle 
• By Two Tangential Lines and Radius
• By a Tangential Line, a Point on the Circumference and Radius 
• By Two Tangential Circles and Radius 
• By a Tangential Line, a Tangential Circle and Radius

Vector

• By x, y, z Components
• By Two Points
• By Two Points

Plane

• By Three Points 
• By a Point and a Parallel Plane 
• By the Coefficient of a Plane Equation a X + b Y + c Z = d 

Pattern

• Linear Pattern by the First Point, Vector and Number of Points 
• Circular Pattern by a Circle, Angular Positions of First Hole, Last Hole and Number of Points 
• Parallelogram Constructed from Two Patterns 
• Random Strings of Points and Patterns
