Vector Cross to STL Conversion

I have a clean vector outline of a church cross and now need it turned into a fabrication-ready STL. Before exporting, the top and bottom sections must be tweaked—certain decorative details will be removed, others added—so the final form looks balanced while keeping the existing proportions everywhere else.

Scope
• Import my vector file (SVG, AI, or EPS) into your preferred CAD software—Fusion 360, SolidWorks, Blender, or similar.
• Edit only the top and bottom arms: add subtle ornamental features where indicated and strip out a few that aren’t needed.
• Extrude to the required thickness, ensuring the model is watertight and free of non-manifold edges.
• Provide the finished STL plus two or three high-resolution screenshots showing front, side, and perspective views so I can verify the geometry before sign-off.
• Optional but appreciated: supply a layered DXF/DWG cut sheet with critical dimensions called out for the metal fabricator.

Deliverables
1. Final STL (millimeter units, oriented for machining or 3-D printing).
2. Preview images.
3. Optional DXF/DWG cut sheet if you can generate it quickly.

The file will be used for laser-cut sheets and further construction details, so dimensional accuracy and clean edges are essential. Let me know if you need clarification on the ornament changes, and include an estimated turnaround time when you respond.
