Urgent: SolidWorks Surfacing Expert UK

​We are a UK luxury golf hardware brand. We have an existing, working 3D engineering .STP (STEP) file provided by our manufacturer, but their internal engineering team has completely distorted the visual geometry and proportions. ​We are looking for an experienced Industrial Product Designer or Mechanical CAD Engineer who is an expert in complex organic/faceted 3D Surfacing (SolidWorks, Fusion360, or Creo) to make a few precise geometric modifications to our master file today. ​We have high-resolution 2D visual mockups and clear photos showing exactly where the factory messed up to guide you. ​🛠️ Tasks Required: ​Center the Peak: The factory has skewed the highest point (the tip) of our central diamond muscle-back cavity wall too far toward the toe side (the right). You must shift this central coordinate back to the true vertical geometric center of the cavity so the left-hand and right-hand diagonal slopes form a perfectly identical, balanced, symmetrical V-shape. ​Fix the Framing Proportions: Shifting the point back to the center will fix the top flat border, which is currently pinching and squeezing our logo layout in the middle. We need you to ensure the flat framing margins above the muscle-back and below it are uniform and equal in thickness, exactly as shown in our layout photos. ​Sharpen the Heel Transition: On the heel side (the left side closest to the hosel), the factory rounded off a hard edge into a lazy curve. You need to flatten this curve out into a sharp, crisp, straight geometric facet/step-down. ​📋 Requirements: ​Timezone/Location: Prefer United Kingdom or European timezones for instant communication. ​Turnaround: Needs to be completed within 24–48 hours (this is a straightforward modification job for someone who knows surfacing). ​NDA: You must be willing to sign a basic non-disclosure agreement before we send over our high-resolution visual mockups and brand files. ​Deliverable: A cleaned up, production-ready .STP or .STEP file that we can hand straight back to our factory's CNC milling machines
