CSWA Practice Problem 1.7

This is Practice Problem 1.7 from the CSWA (Certified SolidWorks Associate) exam preparation series, modeled in SolidWorks. The part is an asymmetric mounting block, featuring a large rectangular base (100mm × 60mm) with a stepped profile and an extruded cut forming a U-shaped channel (23mm wide, 15mm deep) through the top. A circular through-hole (Ø13mm) is positioned on the left face at 15mm from the top and 25mm from the side, while a circular boss (Ø20mm) protrudes from the right face at a reference position of 30mm × 50mm. The front profile includes a 12mm wide × 30mm tall raised tab extending from the top-right corner over a 50mm base span. Units are in MMGS and the total volume of the part is 148,172 mm³. All sketches are fully defined with the origin indicated per design intent. The part is asymmetric. Modeled as part of CSWA exam practice to build proficiency in sketch tools (Lines, Centerlines, Rectangles, Circles) and Boss-Extrude/Extrude Cut features in SolidWorks. Difficulty level: Medium — estimated modeling time: 20 minutes.
