Procedure of building an array by table |
Scroll |
To build an array whose instances’ positions are determined by coordinates of points, use the Array by Table 
command.
Select source objects for construction of an array, specify construction parameters, check whether set values are correct using a phantom and complete the operation.
Source object selection
Specify source objects for construction of an array in the Design Tree or in the graphic region of a model.
There are dissimilarities in the procedures of array construction for objects of different types. Due to that, an array (except for an array of arbitrary objects) cannot simultaneously contain objects of any types. By default the system defines objects’ type after you specify first of the objects – corresponding button will be pressed in the Type group. You may define objects’ type yourself by pressing the required button before specifying objects.
More details about selecting objects being copied...
After you choose objects to be copied, a phantom of the copied object's base point appears in the graphic area in the form of three mutually perpendicular vectors (see section Base point of a 3D object).
Specifying point coordinates
Specify coordinates of points which determine instance positions – basic points Of instances. To specify coordinates, choose source for obtaining data and perform steps according to chosen option. Data source is selected with button group Data source in Array parameters section:
File — point coordinates are read from data file; the required file is selected using the Source File field;
The variable table – point coordinates are entered into Table of modifiable variables; this table is stored in the model.
More about specifying point coordinates...
After you specify point coordinates, a phantom of the array appears in the graphic region.
Choosing point coordinate type
Select the type of the point coordinates for the interpretation of data, obtained from a file or table (see above). To do this, press the relevant button in the Coordinate type group of the Array parameters section:
Rectangular,
Cylindrical,
Spherical.
Points for specifying instance positions will be constructed in the coordinate system of type selected.

Array instance orientation
If point positions are specified in cylindrical or spherical coordinates, you may select method of array instance orientation. To do this, press the relevant button in the Orientation group of the Array parameters section:
Keep original orientation,
Rotate along the radial direction,
Orient by specified object.
More details on orientation of array instances...
Array Advanced Options
If needed, specify advanced options for array construction.
•Choose an arbitrary point as a Base point of the base instance (the position of this point affects the placement of the created instances). To do this, select the Point field in the Base point group of Array parameters section and select the point object required. Details...
If the source object for array construction is a revolution operation, a solid created by such operation or a revolution surface, you can disable using base point projection (it is enabled by default). Details...
•Specify the array name and instance surface properties instances using elements of section Properties.
Extra options for array construction for objects of certain types
Depending on type of objects being copied, following array construction options may be available.
Type Operations — constructing a geometric array. To do this, use the Geometrical Array toggle switch in Array parameters section. Details...
Type Arbitrary — defining the operation application area using elements of the Application area section. Details...
Type Operations or 
Curves, points, construction geometry — modifying dimensions of array instances. To work with dimensions, set the Show Dimensions toggle switch to I (enabled) position. The toggle switch is located in Instance parameters section. Details...
For all types except Solids or surfaces – changing array instance variable values using the table of modifiable variables. To create a table or edit it, click the field name Table of modifiable variables in the Array parameters section. Details...
|
Changing variable values and instance dimensions is not available for geometrical array. |
Deleting and restoring array instances
You can delete certain array instances or restore deleted instances. To do this, open the Deleted instances section. In graphic region, handle dots Delete/restore instance will appear by array instances. Click the handle of the instance to be deleted/restored. Details...
Completing the operation
To complete creation of the array, press the Create Object 
.
If the operation results in a solid consisting of multiple parts, then after completing the operation, the program starts the process of modifying this set of parts. Select the parts to be retained (see section Selecting the parts to keep).
|
Each instance in array of operations inherits the application area of its source element. Details... |
After performing the specified actions, the created array appears in the graphic area of the model, and the respective icon appears in the Design Tree.
To complete operation of the command, click Finish 
button.
