Setting Constraint Limits (New for 5.1)

After a constraint is applied to a rigid body, you are able to set limits to the object's position and the angle, which ensures the constrained rigid body can move or roll within a specified distance or range.

You can use the controls in the Move section to limit the constrained rigid body to move along a specific Local Axis within a certain distance range.

• Lock: Press this button down to stop the constrained object from moving along the axis you specified.
  

  The Local X axis is locked. The constrained object can not move along this axis.	The Local Y axis is locked. The constrained object can not move along this axis.	The Local Z axis is locked. The constrained object can not move along this axis.

• Limit: Press this button down and enter the Min and Max values to decide the moving distance along the specific axis.
  

  A range is set to the Local X axis. The constrained object can only move along this axis within this range.	A range is set to the Local Y axis. The constrained object can only move along this axis within this range.	A range is set to the Local Z axis. The constrained object can only move along this axis within this range.

• Free: Press this button down and the constrained rigid body can infinitely move along the specific axis.
  

  The Local X axis is set free. The constrained object can infinitely move along this axis.	The Local Y axis is set free. The constrained object can infinitely move along this axis.	The Local Z axis is set free. The constrained object can infinitely move along this axis.
  Note:
  In Limit mode: If Min = Max, then the effect equals to the Lock mode. If Min > Max, then the effect equals to the Free mode. Because the constraint applied is aligned to the Local Coordinate of the rigid body, when you want to set the limits for the Move, please turn on the Gizmo (Shortcut: Ctrl + Q) and switch to the Local Move (Press W key to toggle) tool for reference; especially after the object has been rotated. World Move mode. Local Move mode. You need to set the limit settings for the Move in accordance with this coordinate.

You may use the controls in the Rotation section to limit the constrained rigid body to rotate along a specific Local Axis within a certain angular range.

• Lock: Press this button down to stop the constrained object from rotating along the axis you specified.
  

  The Local X axis is locked. The constrained object can not rotate along this axis.	The Local Y axis is locked. The constrained object can not rotate along this axis.	The Local Z axis is locked. The constrained object can not rotate along this axis.

• Limit: Press this button down and enter the Min and Max values to decide the angular range of the rotation by the specific axis.
  

  A range is set to the Local X axis. The constrained object can only rotate along this axis within this range.	A range is set to the Local Y axis. The constrained object can only rotate along this axis within this range.	A range is set to the Local Z axis. The constrained object can only rotate along this axis within this range.

• Free: Press this button down and the constrained rigid body can freely rotate along the specified axis.
  

  The Local X axis is set free. The constrained object can freely rotate along this axis.	The Local Y axis is set free. The constrained object can freely rotate along this axis.	The Local Z axis is set free. The constrained object can freely rotate along this axis.
  Note:
  In Limit mode: If Min = Max, then the effect equals to the Lock mode. If Min > Max, then the effect equals to the Free mode. Because the applied constraint is aligned to the Local Coordinate of the rigid body, when you want to set the limits for the Rotation, please turn on the Gizmo (Shortcut: Ctrl + Q) and switch to the Local Rotate (press E key to toggle) tool for reference; especially after the object has been rotated. World Rotate mode. Local Rotate mode. You need to set the limit settings for the Rotation in accordance with this coordinate. The degrees for the X, Y, and Z axis are as shown in below (the value must be between -180 and 180): X axis. Y axis. Z axis.
