10 SolidWorks Exercises So Hard They Should Be Illegal (Free Download 2025)

Stop scrolling if you think you’re “pretty good” at SolidWorks.Here are 10 parts that silently destroy 95 % of self-proclaimed “advanced” users:

• One has a loft that changes cross-section three times and follows a 3D spline nobody can get right on the first try
• One is a spoon that looks easy… until you try to make the thickness change from 6 mm to 1.5 mm without a single lump
• One is a pipe with five 90° bends that must stay perfectly Ø42.4 × 2.6 mm all the way (good luck keeping the wall thickness)
• One flange elbow will make you question your entire life choices when the section view doesn’t match

I modeled all of them in SolidWorks 2025, took screenshots of every critical step, and made fully dimensioned drawings that you can actually send to a workshop.Want to separate yourself from the crowd who can only do simple brackets?Download the pack (10 × .SLDPRT + 10 × .SLDDRW + PDF + all step-by-step images)

1. “I thought I knew SolidWorks… I was wrong.”
2. “My boss now thinks I’m a wizard.”

Final result – complete technical drawing: Main view, section A-A showing variable wall thickness (20 mm → 40 mm), all radii (R4, R30, R65, R50), overall dimensions and isometric view of the finished part.

Bearing housing end cap (separate part): Start with a simple revolved boss/base from the provided sketch (Ø95 outer, Ø58 inner bore, Ø52 seat, Ø36 shaft bore, 8 mm wall thickness). Add 2.5 mm fillets on all edges and a 2×45° chamfer on the shaft exit.

Tensioning lever arm (separate part): Model using extruded base (50 mm height), extruded boss for the Ø60 mm rounded head, swept boss for the curved arm profile, M6 tapped hole + Ø12 counterbore, two Ø12 through holes and R10/R25 fillets. Final part is mirrored for left/right versions.

Adjustable pipe clamp bracket: Base extrusion from rectangular sketch, two Ø20 circular bosses, Ø10 through holes, 18° angled slot (extruded cut), Ø30 central bore, R20 and R40 fillets on edges, plus small R1 chamfers. All features fully defined for easy modification.

Main curved roller support bracket (the hardest part): Created using Lofted Boss/Base between two sketches (30×20 mm rectangle → 40×40 mm rectangle) with a 3D spline guide curve (R30 + R65 + R50). Central Ø50 mm swept cut along the same path for the roller tube. Finished with R4 fillets on all outer edges and variable wall thickness shown in section A-A.

Machined base block: Rectangular extruded base 200×100×90 mm, large central pocket with 45° and 150° angled faces (extruded cut), Ø12 through hole, curved slot created with swept cut, Ø25 counterbore + Ø12 hole on top face and several fillets/chamfers.

Curved sliding block (Modeling Practice 67): Extruded base 100×75×65 mm, large R20 and R25 rounded top surface using Swept Boss or Boundary Boss, tapered sides with 5 mm wall thickness, R15 fillet on front edge and 5 mm chamfers on bottom edges. Great exercise for advanced surfacing or multi-contour sweeps.

Bent tubular frame (Ø42.4×2.6 mm pipe): Created using Sweep Boss/Base along 3D sketch containing five straight segments and four 90° bends with R60 radius. All bends fully defined in the 3D sketch, table lists exact segment lengths and bend angles – perfect exercise for 3D sketch + sweep + weldment structural members.

Spoon with organic shape and variable thickness: Created using Lofted Boss/Base with five section profiles (from R10 circular bowl to thin 6 mm handle), guide curves for smooth transition, R40/R20/R10 fillets along the edges and variable wall thickness shown in sections. Excellent practice for complex lofts and surface blending.

 90° flanged elbow with complex internal flow path: Built using Revolved Boss/Base for both flanges, Lofted Boss/Base with two circular profiles and guide curves for the smooth R36 bend, Ø18 through bore, four Ø14 bolt holes on each flange (PCD 58 mm), R1 & R2 fillets and 5 mm wall thickness. Section A-A shows exact internal geometry.
