Pivot & Align Tools (PAT) are a set of macros bundled into a quad menu that allow you to perform various object alignment, pivot alignment and object snapping functions... among others. Most of the functions can operate on a selection of multiple objects at once, including grouped objects as part of the selection (open or closed).

NOTE: This script now handles quad setup for both 3dsmax 2025 and above, as well as previous versions of Max.

See online guide in links section. 

Similar to the CAT Muscle Strand object, only mesh-based and accepts modifiers.

Creates surface defined by four splines. The order of picking the splines matters - they should form a closed loop. If you get a weird looking mesh, try once again starting with another of the four splines:

Note that if any of the splines are animated, the resulting mesh is animated, too.

Given and object and a surface, creates a surface-aligned helper and parents the object to it.
