[edit] Limit Location Constraint

[edit] Description

An Object can be moved around the scene in the x, y and z coordinates. This constraint places a limit on the location of an object. A limit can be specified on the upper and lower bounds of each coordinate direction. Separate upper and lower limits can be applied for each of the three spatial coordinates (x, y and z). It is interesting to note that even though the limit constrains the visual and rendered location of the object, the object's data block still allows the object to have coordinates outside the minimum and maximum ranges. This can be seen in the Transform Properties N. When an object is grabbed and attempted to be moved outside the limit boundaries, the object will be constrained to those boundaries visually and when rendered but internally, its coordinates will still be changed beyond the limits. If the constraint is removed, the object will seem to jump to its internally specified location. Finally, if an object has an internal location that is beyond the limit, dragging the object back into the limit area will appear to do nothing until the internal coordinates are back within the limit threshold.

The limits for an object are calculated from its center.

Setting a min and max constraint to be the same value constrains the object's movement in that axis effectively locking changes to that axis while allowing motion in the other axis. Although this is possible, using the Transformation Properties axis locking feature is probably easier.

[edit] Options

minX, minY, minZ

These settings specify the minimum location of the object's center in the x, y and z coordinate spaces. To place a limit, the minimum value in world coordinates of the object center location for each axis can be entered. The constraint will not happen unless the associated button for the axis is also pressed.

maxX, maxY, maxZ

These settings specify the maximum location of the object's center in the x, y and z coordinate spaces. To place a limit, the maximum value in world coordinates of the object center location for each axis can be entered. The constraint will not happen unless the associated button for the axis is also pressed.
