Solidworks Surface Modeling 3

Question 1

What does Curvature Analysis display when applied to a surface in SolidWorks?

Accepted Answer

The variation in curvature across the surface using a color map

Answer

Curvature Analysis color-maps the Gaussian or mean curvature across a surface to help designers evaluate smoothness and identify undesirable flat or sharp regions.

Question 2

What do Zebra Stripes show in SolidWorks surface analysis?

Accepted Answer

Reflective stripe patterns that reveal surface continuity and smoothness

Answer

Zebra Stripes simulate a striped reflective environment to visually reveal G1 and G2 continuity problems, tangent discontinuities, and surface imperfections.

Question 3

What does G2 (curvature) continuity mean when two surfaces meet in SolidWorks?

Accepted Answer

The surfaces share both a common tangent and matching curvature at their boundary

Answer

G2 continuity means the two surfaces are tangent to each other AND have the same rate of curvature change at the shared edge, resulting in a smoother transition than G1.

Question 4

What is the Freeform feature used for in SolidWorks surface modeling?

Accepted Answer

Generating organic shapes by dragging control points on a surface

Answer

Freeform allows interactive reshaping of a surface by manipulating control points and curves directly on the face, enabling organic and sculpted forms.

Question 5

Which continuity condition ensures that two surfaces meet with matching tangent direction but not necessarily matching curvature?

Accepted Answer

G1 (tangent) continuity

Answer

G1 continuity guarantees that adjacent surfaces share the same tangent plane at their boundary, eliminating visible sharp creases while allowing curvature differences.
