Understanding G0, G1, G2 and G3 surface continuity using curvature comb
The curvature comb of a curve is defined as: c ( t) = x ( t) โ d โ ฮบ ( t) n ( t). If we discretize c, then we get the appearance of a comb distributed along x, as illustrated in Fig. 1, hence the term "curvature comb". In our examples, comb curves are shown in red; the input curves are in black. The scaling factor d is needed to bring.

The Surface Curvature Combs tool evaluates curvature quality and smoothness. It displays U and V mapping lines in a graphical display across face boundaries. The tool looks for curvature constraints and extends curvature combs across adjacent faces. The length of each spine on the comb is proportional to the amount of curvature at the point.

A comb appears that displays the curvature of the entity. For splines, the comb crosses the spline at inflection points. The comb changes shape dynamically as you drag the sketch entity and its curvature changes. In the Curvature Scale PropertyManager, move the sliders to adjust the size and density of the curvature comb.

To show the curvature combs of a sketch entity: In an open sketch, right-click a sketch entity and select Show Curvature Combs. A comb appears that displays the curvature of the entity. For splines, the comb crosses the spline at inflection points. The comb changes shape dynamically as you drag the sketch entity and its curvature changes.

A "curvature comb" is a type of graphical diagram added to the plot of a curve which shows a number of "teeth" segments with their bases along the curve, oriented perpendicular to the curve and proportional in length to its curvature. I think you can better understand curvature comb through the following figure.

The curvature combs tool graphically shows the amount of curvature at a given point on a sketch element. A smooth curvature comb is desired to produce the smoothest surface. As shown below, both splines look the same until we look at their curvature combs. The spline with the smoothest curvature combs (i.e. no flat spots or dips exist) will.

Apply the Curve Curvature tool by clicking on a curve or surface isoparm. At this time (while the locator is active) you can adjust the comb plot interactively using the mouse buttons. To go back to an existing comb plot to change the settings: Use Pick โ Locator if it's not already active. Use Windows โ Information โ Information Window.

The comb plot allows for a natural correspondence between the comb and the curve. In a curvature plot, points on the curvature graph are disconnected from points on the curve. However, all points with 0(t) = 0 can be marked on the curve. Curvature plots lend themselves to the display of curvature or radius of curvature numerical values.

Take two arcs. One has a radius of 1 the other has a radius of 2. (By the way, radius is the inverse of curvature, c=1/r, so that infinite curvature means 0 radius [essentially a point], and 0 curvature means infinite radius [essentially a straight line]). Radius can be measured using a "comb" on the side of the arc opposite the center.
