About this service

Send me a PDF, a scanned drawing, a sketch or a photo of the part, and you get back a 3D model built the way an engineer builds it, not traced.

I'm a mechanical engineer with 10+ years in machinery, welded steel structures, process piping and sheet metal, across Spain and Argentina. Certified SOLIDWORKS Professional (CSWP), English C2.

What you will get:
- Fully parametric model: dimensions are named and driven, so revisions take minutes instead of a rebuild
- Native SOLIDWORKS file plus STEP AP214, IGES, Parasolid or DWG/DXF
- Manufacturing drawings with ISO GPS tolerancing (ISO 286 / 2768 / 1302), welding, machining and bending callouts, and BOM
- Sheet metal parts with correct bend allowance and K-factor, bend reliefs and flat patterns that cut and fold right the first time
- Optional linear static FEA in SOLIDWORKS Simulation

Why this matters:
Most cheap CAD work is traced geometry. It looks right until you change a dimension and it breaks. I model with design intent, so the part survives the revisions your project will actually have.

If your drawing has missing dimensions or contradictions, I tell you before I model, not after you've paid for the wrong part.

I work to ISO standards and European practice. Native Spanish, English C2. Available in US and European time zones.

Questions and answers

Native SOLIDWORKS, plus STEP AP214, IGES, Parasolid, DWG/DXF and PDF. Tell me what your manufacturer needs and I'll match it.

Yes. I review the drawing before modelling and tell you exactly what is missing or inconsistent, so you decide the intent rather than me guessing.

Yes. Dimensioned drawings with ISO GPS tolerancing, surface finish, welding and bending callouts, and a BOM.

ISO GPS (ISO 286, ISO 2768, ISO 1302), first-angle projection. I don't certify to ASME Y14.5.

Yes, as an add-on. Linear static FEA in SOLIDWORKS Simulation covering one load case with defined boundary conditions, delivered with stress and displacement results.
