3D STEP File Updates

I have three existing STEP files that need dimensional or feature adjustments. All other geometry, mounting points, and tolerances must remain intact—the only change is specified, and I will provide the exact measurements for each model.

Here’s what I would like:
• Modify the dimensions on all three .step files to the supplied figures without altering other dimensions.
• Return clean STEP files that open correctly in common CAD packages (SolidWorks, Fusion 360, Creo, etc.).
• I expect this project will require modifications during your progress. Expect 6-10 modifications (within the initial requirements) depending on your initial understanding of the provided detailed instructions.

If you spot any knock-on issues caused by the new dimensions (e.g., clearances, interference), flag them and suggest fixes before final export.

Experience with mechanical CAD and a solid grasp of manufacturing tolerances will help this move smoothly. You should have experience with the "explode" feature of AutoCAD or similar software and the ability to show motion assembly of two parts. Once I approve the revised models, the job is complete and I release payment.
