CSWA Practice Problem 1.9

This is Practice Problem 1.9 from the CSWA (Certified SolidWorks Associate) exam preparation series, modeled in SolidWorks. The part is a symmetric rectangular block with corner bosses and cutouts, measuring 175mm × 100mm in footprint with a height of 30mm. All four corners feature identical square bosses (40mm TYP wide, 22mm TYP tall) extruded upward, while matching square cutouts of the same size are cut into the sides, giving the part an interlocking tab-and-slot appearance. The side walls have a uniform thickness of 25mm. Units are in MMGS and the total volume of the part is 944,900 mm³. All sketches are fully defined with the origin indicated per design intent. The part is symmetric. Modeled as part of CSWA exam practice to build proficiency in sketch tools (Lines, Centerlines, Circles) and Boss-Extrude features in SolidWorks. Difficulty level: Medium — estimated modeling time: 10 minutes.
