The CSWE Mechanical Design exam is a 4-hour, hands-on SOLIDWORKS test of about 20 tasks worth 200 points, requiring a minimum of 160 to pass. It demands the CSWP plus four of five CSWPA certifications as prerequisites and tests breadth across advanced parts, assemblies, surfacing, sheet metal, weldments, and drawings. A failed attempt requires a 90-day wait to retake.

1On the CSWE exam, the prerequisite to register is that a candidate must already hold the CSWP plus a specific number of the five CSWPA advanced-topic certifications. How many of the five CSWPA exams are required?
A.Four of the five CSWPA exams
B.All five CSWPA exams
C.Two of the five CSWPA exams
D.Three of the five CSWPA exams
Explanation: The CSWE (SOLIDWORKS Mechanical Design Expert) requires the CSWP-Mechanical Design plus 4 of the 5 CSWPA advanced-topic certifications (Sheet Metal, Weldments, Surfacing, Mold Tools, Drawing Tools). This breadth requirement ensures the candidate is competent across nearly all advanced disciplines.
2A multibody part contains two solid bodies that overlap. To merge them into a single contiguous solid body so that mass properties report one combined body, which operation is most appropriate?
A.Insert a Reference Geometry plane
B.Combine with the Add operation
C.Move/Copy Bodies with a translation
D.Split feature
Explanation: The Combine feature with the Add operation unites multiple solid bodies into one body, useful when overlapping bodies should become a single mass for downstream calculations. Combine also offers Subtract and Common operations for Boolean-style edits within a multibody part.
3You need to create a coil spring that compresses realistically and updates as the assembly moves. The most parametric SOLIDWORKS approach is to model the spring as a swept body and drive its compressed length so it can be configured. Which sweep input controls the number of coils along the helix?
A.The profile diameter
B.The guide curve count
C.The helix/spiral Revolutions parameter
D.The sweep twist-along-path angle
Explanation: A coil spring is typically a circular profile swept along a Helix/Spiral; the helix's Revolutions (or pitch with height) parameter sets the number of coils. Driving the helix height with an equation or configuration lets the spring represent compressed and free states.
4In a large assembly you want to suppress visual and computational load by loading components without their full feature detail, while still allowing mates to solve. Which mode loads only enough data to display and mate components, dramatically reducing memory use?
A.Large Design Review mode
B.Detailing mode
C.Resolved mode
D.Lightweight mode
Explanation: Lightweight mode loads a subset of model data so components display and mate without loading full feature history, reducing memory and rebuild time. Components can be set resolved on demand. It is a core large-assembly performance technique tested at the expert level.
5A design table is used to generate multiple configurations of a part. In the design table header row, what must a cell contain to drive the diameter dimension named 'D1@Sketch1'?
A.The exact parameter syntax $DIMENSION@D1@Sketch1 or the dimension's full name D1@Sketch1
B.The configuration name
C.A reference to a global variable only
D.Just the text 'Diameter'
Explanation: Design table columns are keyed by the dimension's full name (for example D1@Sketch1) or recognized $-keywords such as $STATE, $COMMENT, or $CONFIGURATION. Typing the exact dimension name in the header tells SOLIDWORKS which parameter each row value should set.
6When building a weldment, the structural members are placed along a sketch. To create a custom structural profile not in the default library, you sketch the cross-section and save it. In which file format and library location must a custom weldment profile be saved to appear in the Structural Member dialog?
A.As a .SLDPRT in any folder
B.As a Library Feature Part (.SLDLFP) inside the weldment profiles folder referenced in System Options
C.As a .DXF in the profiles folder
D.As a block in the Design Library
Explanation: A custom weldment profile is created from a closed sketch, saved as a Library Feature Part (.SLDLFP), and stored in the weldment profiles folder (default under ProgramData) referenced under System Options > File Locations. Only then does it populate the Standard/Type/Size lists in the Structural Member PropertyManager.
7A sheet metal flat pattern develops a bend. If the part uses a K-factor of 0.5, what does that value physically represent for the bend?
A.The bend deduction is half the flange length
B.The bend angle is 50 degrees
C.The neutral axis lies at 50% of the material thickness from the inside face
D.The bend radius equals half the material thickness
Explanation: K-factor is the ratio of the distance from the inside face to the neutral axis, divided by material thickness. A K-factor of 0.5 places the neutral (no-stretch) plane at the mid-thickness of the sheet, which governs the bend allowance used to compute the flat length.
8While editing an advanced surface model you must join two adjacent, non-intersecting surface bodies into a single surface body with no gap. Which tool is correct?
A.Trim Surface
B.Offset Surface
C.Thicken
D.Knit Surface
Explanation: Knit Surface combines two or more adjacent surface bodies that share edges into one body, optionally trying to form a solid if the result is fully closed. It is the standard expert step before thickening or converting surface bodies to solids.
9A feature in the tree shows a red error flag and the message 'The sketch plane/face has been deleted.' What is the most direct expert remedy to repair this rebuild error?
A.Use Edit Sketch Plane to redefine the feature's sketch onto a valid plane or face
B.Roll the rollback bar to the top of the tree
C.Suppress the feature permanently
D.Delete the feature and rebuild the entire tree
Explanation: When a sketch loses its plane reference, right-clicking the sketch and choosing Edit Sketch Plane lets you reattach it to a valid plane or face, clearing the error while preserving the feature. This targeted repair is faster than deleting and re-creating downstream geometry.
10On a drawing you apply a geometric tolerance with a feature control frame calling out position with a diameter symbol, a tolerance value, and a primary datum at maximum material condition. The circled-M modifier after the datum letter indicates what?
A.Least material condition applied to the datum
B.Maximum material condition (MMC) applied to the datum feature
C.A projected tolerance zone
D.Regardless of feature size
Explanation: Per ASME Y14.5, the circled M modifier denotes Maximum Material Condition. Applied to a datum reference, it allows a datum shift (bonus) as the datum feature departs from MMC, consistent with functional gauging of mating parts.
