I don't remember the bells and whistles, but it cut suuweet. Had a lot of

nobody could trim a trimmed surf. It had the sweetest vector direction

a check surf area or to extend the cut a bit, click a point, type in an
amount, then type in an angle, or click lines, etc... to get direction, or
free hand it, And you get a visable arrow in the sweetest graphics Ive ever
seen.... and bam, simple surf extend.

Not unusual. Trimming is just a bounding curve on an existing parametric
surface (U&V between 0 & 1 inclusive). The base surface can be extended
beyond that interval, usually, but runs the risk of becoming degenerate or
developing singularities or becoming self-intersecting.
