CORD2R

Rectangular Coordinate System Definition, Form 2

Description: Defines a rectangular coordinate system by reference to the coordinates of three points.

Format:

Example:

Field Definition Type Default
CID Coordinate system identification number. Integer > 0 Required
RID Identification number of a coordinate system that is defined independently from this coordinate system. Integer ≥ 0 0
Ai, Bi, Ci Coordinates of three points in coordinate system defined in field 3. Real Required

Remarks:

  1. Continuation entry must be present.
  2. The three points (A1, A2, A3), (B1, B2, B3), (C1, C2, C3) must be unique and noncollinear. The model translator checks for noncollinearity.
  3. Coordinate system identification numbers on all CORD1C, CORD1R, CORD1S, CORD2C, CORD2R, and CORD2S entries must all be unique.
  4. The reference coordinate system must be independently defined.
  5. A RID of zero (or blank) references the basic coordinate system.
  6. The location of a grid point (P in the sketch) in this coordinate system is given by (X, Y, Z).
  7. The displacement coordinate directions at P are dependent on the location of P as shown below by (, , ).
