Continuity types include the following:
■ G0 (Position). Measures location only. If the edge of each surface is
collinear, the surfaces are positionally continuous (G0) at the edge curves.
Note that two surfaces can meet at any angle and still have positional
continuity.
■ G1 (Tangency). Includes both positional and tangential continuity (G0 +
G1). With tangentially continuous surfaces, the end tangents match at the
common edges. The two surfaces appear to be traveling in the same
direction at the join, but they may have very different apparent “speeds”
(or rates of change in direction, also called curvature).
■ G2 (Curvature). Includes positional, tangential, and curvature continuity
(G0 + G1+G2). The two surfaces share the same curvature.
Bulge magnitude is a measure of how much surface curves or “bulges” as it
flows into another surface. Magnitude can be between 0 and 1 where 0 is flat
and 1 curves the most.
Set Surface Properties Before and After Creation
Set defaults that control a variety of surface properties before and after you
create the surface objects.
■ Surface Modeling System Variables. There are a number of system variables
that are frequently used and changed during surface creation:
SURFACEMODELINGMODE, SURFACEASSOCIATIVITY,
SURFACEASSOCIATIVITYDRAG, SURFACEAUTOTRIM, and
SUBOBJSELECTIONMODE.
■ Properties Inspector. Modifies properties for both the surface objects and
their subobjects after they are created. For example, you can change the
number of isolines in the U and V directions.
