Tapered Aircraft Wing Rib

Create a precise 3D CAD model of an aircraft wing rib for an aerospace engineering project. The model must be a single, watertight solid suitable for import into ANSYS Workbench Static Structural. **Units:** millimetres (mm) **Overall dimensions:** - Length along X-axis: 200 mm - Maximum height along Y-axis: 60 mm - Thickness along Z-axis: 3 mm **Outer profile:** - Create a tapered aircraft wing-rib side profile. - Use a curved upper edge and a curved lower edge that taper towards the right-hand end. - Maximum height must be 60 mm. - Overall length must be exactly 200 mm. - Keep the outer profile symmetric through the 3 mm thickness. **Mounting holes:** - Two circular through-holes. - Diameter: 6 mm each. - Place one near the wide end and one near the narrow end. - Keep both holes completely inside the outer boundary. **Lightening holes:** - Create five circular through-holes in the web. - Hole 1 diameter: 17 mm. - Hole 2 diameter: 20 mm. - Hole 3 diameter: 18 mm. - Hole 4 diameter: 15 mm. - Hole 5 diameter: 10 mm. - Arrange the holes along the length of the rib, following the tapered profile. - Keep adequate material between all holes and between each hole and the outer boundary. - No holes may overlap or intersect the outer edge. **CAD requirements:** - Use a constant thickness of 3 mm. - All holes must pass completely through the thickness. - Avoid gaps, duplicate faces, self-intersections and invalid geometry. - Produce one continuous solid body. - Preserve the specified dimensions. **Export:** Provide a STEP (.step or .stp) file suitable for ANSYS Workbench and a native editable CAD file if available. Also provide an isometric view and a dimensioned engineering drawing. This is a preliminary educational model, not a certified aircraft component.

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.
