4.3.1.49. NXshape¶
Status:
base class, extends NXobject
Description:
legacy class - (used by NXgeometry) - the shape and size of a component.
This is the description of the general shape and size of a component, which may be made up of
numobjseparate elements - it is used by the NXgeometry class
Symbols:
No symbol table
- Groups cited:
none
Structure:
@default: (optional) NX_CHAR
Declares which child group contains a path leading to a NXdata group.
It is recommended (as of NIAC2014) to use this attribute to help define the path to the default dataset to be plotted. See https://www.nexusformat.org/2014_How_to_find_default_data.html for a summary of the discussion.
shape: (optional) NX_CHAR
general shape of a component
Any of these values:
nxflat
nxcylinder
nxbox
nxsphere
nxcone
nxelliptical
nxtoroidal
nxparabolic
nxpolynomialsize: (optional) NX_FLOAT (Rank: 2, Dimensions: [numobj, nshapepar]) {units=NX_LENGTH}
physical extent of the object along its local axes (after NXorientation) with the center of mass at the local origin (after NXtranslation). The meaning and location of these axes will vary according to the value of the “shape” variable.
nshapepardefines how many parameters:
For “nxcylinder” type the parameters are (diameter,height) and a three value orientation vector of the cylinder.
For the “nxbox” type the parameters are (length,width,height).
For the “nxsphere” type the parameters are (diameter).
For nxcone cone half aperture
For nxelliptical, semi-major axis, semi-minor-axis, angle of major axis and pole
For nxtoroidal, major radius, minor radius
For nxparabolic, parabolic parameter a
For nxpolynomial, an array of polynom coefficients, the dimension of the array encodes the degree of the polynom
direction: (optional) NX_CHAR
Any of these values:
concave|convex
