align

Aligns the viewport to the selected face. Thanks to Carl-Mikael Lagnecrantz for some code inspiration.

Tutorial:
Select an editable poly object, select a face, run the script. Now you have a new view perpendicular to that face.

The following will let the user move objects along their Z axis to fit a specified surface. Such a script can be used to automatically plant trees, poles etc. on the ground.

This script is straight out of the 3ds Max MAXScript reference file. Its part of the MAXScript 'How To' lessons that teaches how to use MAXScript with practical problems. Load your MAXScript reference (the one that ships with 3ds Max) and do a search for 'align surface' and it'll be the first result.

I did not write this script I merely copied the code here as aligning to a surface is a very common request. Make sure to read the other 'How To' tutorials in the 3ds Max MAXScript reference - they're all really good!

[Admin update - this is a commercial script]

UV Tools is a 3d studios max plugin designed for making the process of
UVW mapping easier. Designed mainly for use directly while in Editable
Polygon mode, you can use it directly alongside while you are modeling
or editing your geometry.

Script for aligning and looping vertices (uv's) inside the UVW unwrap dialog.
