This checking approach can be time-consuming if you check a very large model. One way of speeding the process is to increase the distance between checks in the Surface Continuity Options box. You can press Esc to terminate the check before it is completed. A series of messages appear in the promptline to indicate the maximum continuity deviations. Once the check is complete, one of the following messages is displayed on the promptline.
Surfaces are positionally continuous.
Left mouse button - Using Combs Comb display demonstrates the differences in continuity along a surface boundary. Alias will create a comb indicating the relative size of the gaps, tangency and curvature breaks along the surface boundary. The longer the line in the comb, the larger the break on the surface. Each segment of the comb is drawn in the surface normal direction and represents the gaps, curvature, and tangent continuity breaks at specific points along the surface boundary. Scale the comb Your left mouse button scales the comb.
