Linear repetition of objects
Introduction
The operation Linear repetition of objects allows for the duplication of N times the objects according to a vector.
Structure of the operation Linear repetition
The operation Linear repetition of the objects is described by:
 A coordinate system for the creation of points (active coordinate system in the list available on the graphic View)
 A list of objects to repeat
 The components on Ox, Oy and Oz of the vector of repetition
 The number of repetitions
 The appearance of the resulting objects (color and visibility)
Dialog box  Illustration 

Result
The creation of an operation of Linear repetition has as results:
 A geometric operation LINEAR_1.
 As many geometric operations as the objects repeated LINEAR_1_1, LINEAR_1_2… (it permits to isolate each object duplicated and to use them independently then).
 As many objects as the objects to turn symmetric OBJ_ LINEAR _1_1, OBJ_ LINEAR _1_2, …
 The addition of the geometric operation LINEAR _1 in the list of geometric operations of each of origin objects
 The addition of the geometric operations LINEAR_1_1, LINEAR_1_2… in each of the objects resulting from the repetition (OBJ_LINEAR _1_1, OBJ_LINEAR _1_2, …)

Creation of a linear repetition
The creation process of a linear repetition is presented in the table below.
Stage  Description 

1  Choice of the coordinate system of creation 
2  Opening the dialog box Linear repetition 
3 
Choice of the name of the generated Geometric operation (by default: LINEAR_1) 
4  Choice of objects to repeat 
5  Enter the coordinates of repetition vector (DX, DY, DZ) 
6  Enter the number of repetitions 
7  Validation by clicking on OK 
Limitations
In the modification only the vector of repetition and the number of repetitions are modifiable.
The list of repeated objects is not modifiable.
Example of linear repetition
By means of an example, here are the geometric operations and the objects that are created during an operation of linear repetition of objects.
Studied example: repetition of a cone (number of repetitions = 2)
