Have a 2D Drawing but Need a 3D CAD Model?

Send me what you have. I’ll build the CAD.
PDF • DWG • DXF • Sketch • Existing Part

I turn existing drawings and engineering information into clean, editable 3D CAD for
manufacturing, prototyping, and design.

You provide the drawing. I build the model.

No engineering firm. No long-term contract. No need to hire another designer. Send me the
information you already have and I’ll tell you what it will cost.

Services

2D Drawing → 3D CAD Model


Turn dimensioned drawings, PDFs, DWGs, DXFs, and sketches into clean, editable 3D CAD models.

Legacy CAD → Modern 3D


Convert old, outdated, incomplete, or unusable CAD files into current, editable 3D models.

Existing Part → 3D CAD

About Eric Sweet

Owner/Designer


I’m a mechanical CAD designer with a background in mechanical drafting, 3D modeling, assemblies, and manufacturing documentation. I specialize in taking existing designs, sketches, drawings, measurements, and reference information and turning them into clean, accurate, parametric CAD models. My work focuses on producing clean, well-structured CAD that minimizes rework and clearly communicates design intent for manufacturing and prototyping. I have experience developing automotive components and tooling using platforms such as AutoCAD, CATIA V5, SolidWorks, and NX, and I’m comfortable working with complex multi-part assemblies throughout the design process. My goal is to provide practical CAD support that helps inventors, product builders, and small businesses move from an idea or existing design toward a usable prototype or finished product.

Outside of professional drafting, I’ve spent more than 20 years working with tools and materials through woodworking and fabrication projects. That hands-on experience helps me approach CAD with a practical understanding of how parts are actually made and assembled.

Software & Filetypes
Primary: Fusion 360
Experience: Catia V5, UGNX, Solidworks, AutoCad, Fusion 360 (automotive/mechanical background)
Deliverables: STEP, IGES, Native CAD files, PDF drawings (as needed)
