D-Shaped Bracket

Create a 3D CAD model of a bracket. Units: inches. Use the origin at the front-bottom-left corner, X = length, Y = depth (back), Z = height. BASE BODY - Sketch the plan view (XY) as a slot/"D" shape: a 4.00 x 2.00 rectangle from x=0 to x=4.00, plus a semicircular end of radius R1.00 centered at (x=4.00, y=1.00). Overall length is 5.00, width is 2.00. - Extrude 3.00 in Z. The whole part is 3.00 tall, with a square left end and a fully rounded right end. SEMICIRCULAR NOTCH - On the front face (XZ plane), draw a circle of radius R1.50 centered at x=2.50, z=3.00 (on the top edge). Only the lower half is inside the part. - Cut through the full 2.00 depth (all in Y). This leaves a semicircular channel with its lowest point at z=1.50, running from x=1.00 to x=4.00. - The left leg is then 1.00 wide at the top (x=0 to 1.00). The right end is full height at x=4.00. HOLES (both diameter 0.50, through all) 1. Horizontal hole: on the front face, centered at x=0.50, z=0.50, drilled through the full 2.00 depth in Y. 2. Vertical hole: on the top face, centered at the center of the R1.00 round end (x=4.00, y=1.00), drilled through the full 3.00 height in Z. Final dimensions: 5.00 (L) x 2.00 (W) x 3.00 (H). Keep all edges sharp, with no fillets or chamfers.

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.
