CSWPA-SU is a hands-on SOLIDWORKS advanced surfacing exam of about 19 tasks delivered in roughly 90 minutes through the Tangix TesterPRO client. It requires a 75% score, costs about $19.95 per attempt, and enforces a 14-day retake wait. Tested skills span surface creation, editing and repair, curve tools, and continuity, with surface creation features carrying the heaviest emphasis.

1Which SOLIDWORKS surface feature creates a surface bounded by sketches, edges, or curves in two perpendicular directions and is preferred when you need high-quality continuity control in both directions?
A.Boundary Surface
B.Planar Surface
C.Extruded Surface
D.Offset Surface
Explanation: Boundary Surface uses curves or edges in Direction 1 and Direction 2 and offers per-edge tangency/curvature control, producing the highest-quality blends among the basic surface tools. This is why it is favored for complex consumer-product shapes on the CSWPA-SU exam.
2On the CSWPA-SU exam you must combine several adjacent surface bodies into a single continuous body before thickening. Which command joins coincident-edge surface bodies into one body?
A.Trim Surface
B.Knit Surface
C.Move Face
D.Untrim Surface
Explanation: Knit Surface stitches two or more adjacent surfaces that share coincident edges into a single surface body, and if the result is fully closed it can be made into a solid. It is a required step before Thicken when several patches must act as one body.
3A knit set of surfaces forms a fully closed, watertight volume. What must be true for SOLIDWORKS to convert that knit surface body directly into a solid body using the Knit Surface option?
A.All surfaces must be offset surfaces
B.The surfaces must all be planar
C.The enclosed volume must be completely closed with no gaps
D.The surfaces must share a single sketch
Explanation: When 'Try to form solid' is enabled, Knit Surface produces a solid only if the knitted surfaces enclose a completely sealed volume with no gaps. Any open edge prevents solidification, so candidates must inspect open edges first.
4Which feature thickens a surface body or a knit set of surfaces into a solid by adding material to one or both sides of the surface?
A.Planar Surface
B.Ruled Surface
C.Offset Surface
D.Thicken
Explanation: Thicken adds a specified wall thickness to a surface body, generating a solid with the surface as one of its faces. You can thicken to side 1, side 2, or both sides, which makes it a primary surface-to-solid tool on the exam.
5You must create a smooth patch that closes an open region bounded by several existing surface edges, with the option to constrain the patch to be tangent or curvature-continuous to the surrounding faces. Which feature is the best fit?
A.Filled Surface
B.Extruded Surface
C.Revolved Surface
D.Offset Surface
Explanation: Filled Surface constructs a patch within a closed boundary of edges and/or curves and lets you set Contact, Tangent, or Curvature continuity per boundary edge. It is the standard tool for closing gaps and patching faces on the CSWPA-SU exam.
6When using Trim Surface with the 'Mutual' trim option, what role do the selected surfaces play?
A.One surface is the tool and the others are kept
B.The surfaces trim each other at their intersection
C.Only sketches can be used as trim tools
D.The surfaces are knitted before trimming
Explanation: In Mutual trim mode, two or more intersecting surfaces act as trimming tools for one another, and you choose which pieces to keep or remove along the shared intersection. Standard trim mode instead uses one explicit tool to cut a separate target.
7An imported surface body has a face that was trimmed away, leaving a hole. You want to regenerate the missing portion by extending the surrounding surface back to its original mathematical extent. Which command does this?
A.Move Face
B.Replace Face
C.Untrim Surface
D.Delete Face
Explanation: Untrim Surface removes trim boundaries and extends the underlying surface back to its natural (untrimmed) extent, optionally filling internal loops. It is the direct way to restore geometry lost to trimming on imported or repaired bodies.
8Which Delete Face option removes the selected faces and then attempts to extend and trim the adjacent faces to close the resulting opening, effectively healing the body?
A.Delete and Keep
B.Delete
C.Delete and Patch
D.Delete and Fill
Explanation: Delete and Fill removes the chosen faces and creates a single face that patches the gap, with an option to keep the result tangent to neighbors. It is heavily used to clean up imported geometry on the surfacing exam.
9To create a surface that transitions smoothly between two or more profile sketches, optionally using guide curves and a centerline, which feature should you use?
A.Lofted Surface
B.Offset Surface
C.Ruled Surface
D.Planar Surface
Explanation: Lofted Surface blends between two or more profiles and can be shaped with guide curves, a centerline, and start/end tangency to neighboring faces. It is the classic multi-profile transition tool tested on CSWPA-SU.
10In a Lofted or Boundary Surface, what is the primary purpose of a guide curve?
A.To set the wall thickness of the surface
B.To control the path and shape of the surface between profiles
C.To convert the surface into a solid
D.To define the trim boundary
Explanation: Guide curves steer the contour of a loft or boundary surface between its profiles, controlling how cross-sections evolve along the feature. They are essential for matching styling intent and forcing the surface through specific points.
