Procedure of array by grid construction |
Scroll |
To construct an array with instances located in the nodes of a parallelogram grid, use the Array by grid 
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.

After you choose objects being copied, a phantom of the array appears in the graphic region.
Setting grid parameters
Specify array construction parameters for each of grid axes. To do this, use elements of Parameter Panel in the section Array parameters. The parameter setting elements for the first axis are located in the Direction 1 group, while for the second axis — in the Direction 2 group.
•Axis Direction
The following methods for setting the direction are available:
•Selection of the guiding object,
•Building a vector 
,
•Setting the slope angle for the first axis and the included angle for the second axis.
More details on specifying the axis direction...
•Number of instances by the axis
Enter number of instances (including the base instance) to be located along the axis, in the Instances by Direction field.
•Step by axis grid
Choose method for setting a pitch with buttons of the group Distance between : Adjacent instances 
or Extreme instances 
— and enter the step value in the field Distance 1/Distance 2.

Array Advanced Options
If needed, specify advanced options for array construction.
•Specify the number of the base an instance in an array. This will change positions of array instances. Number of the base instance is set using field group Base instance of the Additional parameters section:
•By direction 1 – number by the first axis,
•By direction 2 — the number by the second axis.
•Choose instance placement option inside the grid using Scheme button group in the Additional parameters section. 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...
Operations or 
Curves, points, construction geometry — modification of array instance dimensions. 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, click the field name Table of modifiable variables in the Instance parameters section. Details...
|
Changing instances through variables and dimensions table is not allowed 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 Create Object 
button.
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 
.
•The number of array instances, direction of grid axes and steps of axis can be specified in the model's graphic area using defining points.
•You can set linear and angular parameters using the geometrical calculator.
•You may assign tolerances, specified in linear or angular units, to operation parameter values. To do this, call the Tolerance command located in the menu of the required parameter, or click the icon 
displayed in the parameter field (the icon is displayed if a tolerance is assigned to the parameter value). More details on assigning tolerance...
