When drawing a Line spline (page 1–270) or
Wall object (page 1–223),OrthoSnappingMode
constrains line creation to the horizontal or vertical
directions relative to the active grid. That is, with
Ortho on, you can draw on ly lines that are parallel
to lines of the active grid. Ortho is particularly
useful for drawi ng plans where all lines must be at
90 degrees to each other, such as a house plan. To
constrain line-draw ing to other angle increments,
use Polar Snapping Mode (page 2–39) instead.
Impor tant: By default, Ortho Snapping Mode is not
directly accessible in the 3ds Max user inter face. To add
itasabuttonontheSnapstoolbar,followthis procedure
(page 2–39).
The following provisions apply to using Ortho:
• Use of Ortho is mutually exclusive of use of the
Polar Snapping Mode toggle (page 2–39);only
one can be active at a time.
• Ortho Snapping applies primarily to the
creation of line splines and wall objects. It can
be used while creating other objects, but results
arelikelytobeunsatisfactory.
