Examples of Key Entity in a sentence
The Key Entity has a principal place of business or significant operations in a Qualifying Country.
In this case, it is called a Parametric Indirect Key Entity.A Key Entity can be associated not only with a point, a line or an oriented point but also with a combination of them (indicated as an array).
A Key Entity is a geometric primitive (point, line or ori- ented point) associated with either the geometric or struc- tural representations of a Component, or simply located in its local reference frame.
In this figure, EFoC is an oriented point on a contour, EFiC is a pixel on an image oriented by the normal of the image, EPW is a point on the structure of an image, and EFM is a point on a mesh.The parameters of a Parametric Direct Key Entity include the related Component, the related representation (geometric.
A Parametric Key Entity can be represented by a point, a line or an oriented point so as to represent a plane.
Intermediate level (Key Entity and constraint)The intermediate level specifies how the Components are located the ones with respect to the others in the global reference frame of the virtual environment.
The dimension of a Key Entity corresponds to the number of R3 elements used to specify its representation.
A table classifying all the key entities by their dimensions is presented in Table 2.Finally, from the presented specification of Key Entities, it can be noticed that the Parametric Key Entity can be associated with the geometric and/or the structural repre- sentations of a Component, while in traditional CAD sys- tems, the key entities used to specify constraints in assemblies are only located on its geometric layer.
A Geometric Key Entity of a Component is only related to the local reference frame of the Com- ponent, and it is not modified when its geometric or structural representations evolve.
The parameters to define a Parametric Indirect Key Entity contain the already specified Key Entities and some numeric parameters explaining their relations.All the key entities are represented in a 3D space.
