The prompt
Here is a crisp and clear prompt you can use in a text-to-CAD system to generate the bevel gear with the specified dimensions. Text-to-CAD Prompt: Create a parametric 3D model of a straight bevel gear with a stepped cylindrical body, made of steel. The dimensions are based on the provided specification sheet. Construct the gear in the following order of operations: Main Body: Extrude a 29.89 mm diameter cylinder from the origin. Set the total height of the cylinder to 45.22 mm. Gear Teeth (Tapered Cone): Define the top profile of the gear as an 18.42 mm diameter circle. Extrude and taper this top profile downwards to meet the main cylinder, forming the gear's conical section. This conical section will have 10 straight teeth equally spaced around its perimeter. The teeth have a whole depth (radial height) of 3.6 mm. Internal Square Bore (Bottom): On the bottom face of the gear (at the origin), create a 10.81 mm by 11.22 mm rectangular sketch. Extrude this rectangle upwards into the gear body to a depth of exactly 16.49 mm to create the drive socket.
Parameters
