   Anchor

   By default, the application positions each instance with respect to the center of gravity or the element to be duplicated. To change this position, use the anchor field: click the Anchor field and select a vertex or a point. Note that contextual commands creating the anchors you need are available from the Anchor field: Create Point: for more information, see Creating Points Create Midpoint: creates the midpoint of the line you select Create Endpoint: creates the endpoint of the line you select Create Intersection: see Creating Intersections Create Projection: see Creating Projections

   If you create any of these elements, the application then displays the corresponding icon next to the Anchor field. Clicking this icon enables you to edit the element.

5. Click OK to create the pattern.
