pmit_create_cadcs

Create object of PmitCadCSH class

Syntax

PmitError = pmit_create_cadcs(PmitCadCSH* const pmitCadCSHOut, const char* name, const char* nodeID, double rotation[9], double trans[3])

Description

PmitError = pmit_create_cadcs(PmitCadCSH* const pmitCadCSHOut, const char* name, const char* nodeID, double rotation[9], double trans[3]) returns an error status PmitError.

With pmit_create_cadcs, you can create an object of PmitCadCSH class to represent a coordinate system in an API CAD model.

Input Arguments

name

String naming the coordinate system

nodeID

String uniquely identifying the coordinate system for associativity purposes

rotation

Double-type real rotation 9-vector specifying rotational transformation of the origin of this coordinate system with respect to its parent CAD model.

trans

Double-type real 3-vector specifying translation of the origin of this coordinate system with respect to its parent CAD model.

Output Arguments

pmitCadCSHOut

Handle object of PmitCadCSH class representing a coordinate system in an API CAD model

Orthogonal Matrix

A matrix R is orthogonal if it satisfies the matrix multiplication rule RT*R = R*R T = 1, where 1 is the identity matrix.

Rotational Transformation: Rotation Matrix and Rotation Vector

The rotation vector input is a 9-vector, defined from the 3-by-3 orthogonal rotation matrix R, that represents the rotational orientation of a CAD model component with respect to its parent CAD model.

You define the rotation 9-vector column-wise:

rotation = [R(1,1) R(2,1) R(3,1) R(1,2) R(2,2) R(3,2) ...
           ... R(1,3) R(2,3) R(3,3)]
