Construction Entities

A construction entity is an image of an entity that can help you plan and position new entities in the graphical display area. The construction entity is not a real entity and does not print out. The Change Construction Lines tool enables you to change any entity into a construction entity, or to change a construction entity back to a regular entity.

To work with a construction entity:

1. Click the Select option from the Sketcher toolbar. Or press exit until you are in Select mode.

The cursor changes to a black pointer .

2. Click an entity that you wish to change to a construction entity. The entity changes to dotted red when clicked, then dotted black as the cursor is moved away from it.

3. Click the Change Construction Lines tool .

The entity changes to dashed blue, showing that it is no longer a regular entity, but a guide to planning other entities.

For example, you can use a circle construction entity to guide you to define circles that are tangent to the Construction circle.

Tip: You can click the construction entity and select the Change Construction Lines tool again to change the construction entity back into a regular entity.
