The Constraint Settings icon opens a menu where you can adjust options related to constraints. Constraint Settings is available opposite the sketch menu when you are working in sketch mode.
Auto-constraining
The Auto-constraining option can be adjusted to control if constraints are added to your sketch automatically or manually. Explore the sections below for a summary of sketch behavior based on the state of this setting.
Auto-constraining = Off
As you create sketch elements, the only constraints that are automatically created are between connected endpoints or midpoints. To create additional constraints, you must select sketch elements and use the constraints menu at the right.
Auto-constraining = On
As you create sketch elements, constraints for connected endpoints and midpoints are automatically created, as well as constraints for:
- Horizontal/Vertical
- Perpendicular
- Tangent (when an arc is created at an endpoint)
- Coincident
Use Sketch Guide Lines to align geometry and automate these constraints. For more information on Sketch Guide Lines, see Snapping Options.
For more information on types of constraints, see Examples of constraint types.
Visibility for constraints
The Visibility constraint setting controls how constraint icons for the active sketch are shown in the design space.
The two options are:
- Selection-based
- When selected, constraint icons are only shown for selected sketch elements.
- Show All
- When selected, all constraint icons for the active sketch are shown in the design space.
For more information on constraint icons, see Adding and removing constraints.
