Creating Patterns of Entities

Use the Pattern command to create copies of specified entities in a linear matrix or circular pattern. The created entities inherit all properties of the original entities such as Layers, LineColors, LineStyles, and LineWeights.

To create a linear pattern:

1. Do one of the following:
   • On the menu, click Modify > Pattern.
   • Type Pattern.
2. In the dialog box, select Linear.
3. Click Select entities , select the entities to generate the pattern, and press Enter to complete the selection.

   The dialog box disappears until your selection is complete.

4. Under Number of elements:
   • For Horizontal axis and Vertical axis, type the number of elements. Alternatively, you can use the plus and minus buttons to increase, respectively decrease the values.
   • For Spacing between elements, define spacings between the elements 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.
5. Click .

  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 to generate the pattern.

To create a circular pattern:

1. Do one of the following:
   • On the menu, click Modify > Pattern.
   • Type Pattern.
2. In the dialog box, select Circular.
3. Click Select entities , select the entities to generate the pattern, and press Enter to complete the selection.

   The dialog box disappears until your selection is complete.

4. Select Orient elements about axis to rotate the entities as they are patterned, otherwise they maintain the alignment of the source entity.
5. Under Settings, set:
   • 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.

     According to your selection, set the corresponding parameters:

     • Angle between (if required) is 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. The pattern is drawn counterclockwise for positive angles and clockwise for negative angles.
     • Total number if required. The number of items includes the original entity.
6. Under Element base point, set:
   • Use last entity selected. Uses the base point from the last item you selected.
   • X and Y. Type values or click Pick Base Point .
7. Under Axis point, set:
   • X and Y. Type values for the center point of the pattern or click Pick Center Point .
8. Click .

  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 to generate the pattern.
