Creating Patterns of Entities
Use the Pattern command to create copies of specified entities
According to these types, the Pattern dialog box displays three tabs (Circular, Linear, and Path).
Use the Pattern command to create copies of specified entities in a circular pattern or in a linear matrix.
The copied entities inherit all properties of the original entities such as Layers, LineColors, LineStyles, and LineWeights.
Associative Patterns
You can create associative and non-associative patterns. Entities within associative patterns retain their relationships. Associative patterns let you edit them in their entirety instead of changing the individual items in the pattern. In non-associative patterns, editing one item does not affect the other items.
To make patterns associative, activate the Associative option in the Settings section of the Pattern dialog box.
To edit associative patterns, see Editing Associative Patterns.
To undo the associativity of patterns, use the Explode command.
Circular patterns
To create a circular pattern:
- Do one of the following:
- On the ribbon, click Home > Modify > Pattern.
- On the menu, click Modify > Pattern.
- Type Pattern.
- In the dialog box, under Pattern type, select Circular.
- Click Specify entities , select the entities to generate the pattern, and press Enter to complete the selection.
The dialog box disappears when your selection is complete.
In the dialog box, the collection of specified entities is referred to as elements.
- Under Settings, set:
- Associative. Specifies whether the pattern is created associatively or non-associatively.
- Clockwise. Specifies whether the direction of the polar array is clockwise or counterclockwise. The option is available only for associative circular patterns.
- Base pattern on. Select an option:
- Angle Between and Total Number of Elements
- Fill Angle and Angle Between Elements
- Fill Angle and Total Number of Elements
- Angle between (if required). Specifies the included angle between the base points of the pattern entities and the center of the pattern. Type a positive value or click Pick angle between items .
- Fill angle (if required). Type a positive or negative value or click Pick angle to fill . The default for the angle to fill is 360° - a full circle pattern. A value of zero is not allowed.
- Total number (if required). Specifies the resulting number of copies in the circular patten (including the source).
- Under Element base point, set:
- Use last entity selected. Uses the base point from the last entity you specified.
- X and Y. Type values or click Pick base point to specify the base point in the graphics area.
- Under Axis point, for X and Y, type values for the center point of the pattern or click Pick center point .
- Select Orient elements about axis to rotate the copies as they are patterned, otherwise they maintain the alignment of the source entities.
- Click OK.
Note: In the Pattern dialog box, click Preview to check the resulting pattern without creating it. You can use this option and return to the dialog box as many times as needed, then click OK to generate the pattern.
Linear patterns
To create a linear pattern:
- Do one of the following:
- On the ribbon, click Home > Modify > Pattern.
- On the menu, click Modify > Pattern.
- Type Pattern.
- In the dialog box, under Pattern type, select Linear.
- Click Specify entities , select the entities to generate the pattern, and press Enter to complete the selection.
The dialog box disappears when your selection is complete.
In the dialog box, the collection of specified entities is referred to as elements.
- Under Settings, set:
- Associative. Specifies whether the pattern is created associatively or non-associatively.
- For Horizontal axis and Vertical axis, type the number of copies.
- For Spacing between elements on, define spacing between the copies and an angle for the pattern:
- Horizontal axis. Specifies the distance between columns. Click Select column offset to identify the offset using two points in the drawing. If the column offset is a negative value, columns are added to the left.
- Vertical axis. Specifies the distance between rows. Click Select row offset to identify the offset using two points in the drawing. If the row offset is a negative value, rows are added downward.
- Pattern angle. Specifies the angle to control how the copies are arranged. Click Select angle to specify the angle using the pointer.
Note: In the Pattern dialog box, click Preview to check the resulting pattern without creating it. You can use this option and return to the dialog box as many times as needed, then click OK to generate the pattern.
Patterns along a path
To create a pattern along a path:
- Do one of the following:
- On the ribbon, click Home > Modify > Pattern.
- On the menu, click Modify > Pattern.
- Type Pattern.
- In the dialog box, under Pattern type, select Path.
- Click Specify entities , select the entities to align along a path, and press Enter to complete the selection.
The dialog box disappears when your selection is complete.
In the dialog box, the collection of specified entities is referred to as elements.
- Click Specify path and select the entity that defines the path to align the specified entities along.
The path can be a Line, PolyLine, Arc, Circle, Ellipse, or Spline.
- In Settings, set:
- Associative. Specifies whether the pattern is created associatively or non-associatively.
- Base pattern on. Select an option:
- Distance Between and Total Number of Elements. Allocates the copies along the path at specified intervals with the specified total number. If the calculated pattern length exceeds the length of the path, the distance between the copies is reduced.
- Divide Equally. Allocates the number of copies evenly along the total length of the path.
- Measure Equally. Allocates the copies along the path at intervals you specify.
- Distance (if required). Specifies the intervals between the copies. Click Specify spacing between elements to identify the distance in the graphics area.
- Total number (if required). Specifies the resulting number of pattern copies in the path patten (including the source).
- Under Element base point, set:
- Use last entity selected. Uses the base point from the last entity you specified.
- X and Y. Type values or click Pick base point to specify the base point in the graphics area.
- Under Rows, set:
- Count. Specifies the number of rows in the pattern.
- Distance. Specifies the distance between the rows. If the distance is a negative value, rows are added downward. Click Specify spacing between elements to identify the distance in the graphics area.
- Under Element alignment, set:
- Click OK.
Note: In the Pattern dialog box, click Preview to check the resulting pattern without creating it. You can use this option and return to the dialog box as many times as needed, then click OK to generate the pattern.
