Interlocking Block Top Profile

Create a 2D CAD sketch of the TOP EDGE profile for a 16.000-inch interlocking concrete block. Requirements: • Overall profile width = 16.000 inches. • The profile must be perfectly symmetrical about the 8.000-inch centerline. • Create exactly two identical downward-facing trapezoidal notches. • Position the notches so they are mirrored about the centerline. • The profile must be designed so that, when this same profile is rotated exactly 180°, the rotated profile nests completely into the original profile with full contact and no interference. • The top profile is the master geometry. Do not create a separate bottom profile. • The nesting geometry must be self-mating after a 180° rotation. • Only the inside walls of each notch shall have a 5.0° draft angle. • All horizontal surfaces remain horizontal. • The left and right ends must be identical. • Output only the continuous 2D line profile. No dimensions, text, holes, square openings, or shading.

Parameters

Every value above is a live dimension. Open a model like this in the editor and each one becomes a slider you can drag before exporting.
