You can apply relationships as you draw and place elements by using the relationship indicators that appear by the pointer. You can also apply relationships to elements that you have already placed on the drawing sheet.

Applying Relationships to Existing Elements

To apply relationships to elements that you have already placed on the drawing sheet, click a button on the Change toolbar (in Catalog), or the Relationship toolbar and then select the elements you want to relate. When you apply a relationship between elements, the elements are modified to reflect the relationship. If Maintain Relationships is set when you use the commands on the Change or Relationship toolbar to add relationships to your drawing, the added relationships will be maintained.

For example, selecting Equal and clicking two circles makes the two circles equal in size.

If a line and arc are not tangential, applying a tangent relationship modifies one or both elements to make them tangent.

When you use commands on the Change or Relationship toolbar, the software allows you to select only elements that are valid input for that command. For example, when you use Concentric, the command allows you to select only circles, arcs, and ellipses.

Perhaps you begin designing with a few key design parameters. You would usually draw known elements in relation to one another and then draw additional elements to fill in the blanks.

As you draw and add elements to the drawing, the relationships are maintained, and additional relationships are applied.

Modifying Elements That Share Relationships

If two elements share a relationship, the relationship is maintained when you modify either one of the elements. For example, if you move a circle that has a tangent relationship with a line, the line also moves. The elements remain tangent.

If you move a circle that does not have a tangent relationship with a line, the line does not move.

Other elements that share relationships maintain them in the following ways:

If a line and an arc share a tangent relationship, they remain tangent when either is modified.

If a line and arc share a connect relationship, they remain connected when either is modified.

If two lines are horizontal, they remain horizontal even if you change the position and length of one of the lines.

Deleting Relationships

You can delete a relationship as you would delete any other element. You select a relationship handle, and then click Delete. Relationships are automatically deleted when their deletion is necessary to allow a modification to occur. For example, if you rotate an element that has a horizontal relationship applied to it, the relationship is automatically deleted.

If you want to change an element by adding or removing a relationship, and the element does not change the way you expect, it may be controlled by a driving dimension. You can toggle the dimension from driving to driven, and then make the change.
