Project brief

This project brings two related mounting-bracket design variants together in one CAD case study. Both share twin cylindrical bosses with upper bores, a recessed connecting saddle, an obround opening in the vertical body and a stepped rear profile. A shaded solid model communicates the three-dimensional form, while front, side and plan projections define the individual features. Variant A provides coordinated orthographic drawings, a magnified radius detail and section E–E, which reveals the relationship between the upper boss, connecting body and rear steps. Its source drawing specifies a 99 mm overall width, 22 mm upper-hole diameter and 36 mm depth. Variant B presents an alternative dimensioned drawing set, with an overall-width callout of 104.00, an upper-bore callout of Ø18.00, a body-width callout of 64.00 and a depth callout of 36.00. These annotations retain their source drawing units. Each drawing is labelled by variant so that different feature dimensions can be reviewed in their proper context. The five selected visuals include a shaded model, orthographic projections and the section view, demonstrating solid modelling, hidden-line representation, dimension placement and technical communication. The deliverable is a CAD documentation study; the supplied material does not establish physical fabrication, tolerance validation, load testing or measured performance.

The engineering challenge

Communicate two closely related bracket geometries through clear model, projection and section views while keeping each variant’s dimensional callouts consistent.

Engineering approach

  1. Represented the shared twin-boss, obround-opening and stepped-body geometry in a shaded solid model.
  2. Organized front, side and plan projections into clearly labelled Variant A and Variant B drawing sets.
  3. Used the magnified radius detail and section E–E to explain Variant A’s upper transition and internal geometry.
  4. Retained each variant’s source dimensions and unit conventions when documenting its bores, overall envelope and support body.
  5. Selected complementary CAD views to show spatial form, feature location and internal section geometry.
