Hitesh G.

Overview / About Me:

I am a mechanical CAD designer specializing in Siemens NX (Unigraphics). I help clients transform rough sketches, concepts, and technical requirements into high-precision 3D models and production-ready manufacturing drawings.

Whether you need a functional part modeled from scratch, reverse engineering, or standard 2D fabrication drawings, I deliver accurate, detailed CAD assets tailored to your engineering standards.

Core Services:

3D CAD Modeling: Parametric part and assembly modeling, sheet metal design, surface modeling, and reverse engineering.

2D Technical Drafting: Comprehensive fabrication drawings, section views, exploded views, and bill of materials (BOM).

Standards Compliance: Proper application of GD&T (Geometric Dimensioning and Tolerancing) to ensure accurate manufacturing fit and function.

File Conversion & Cleanup: Converting 2D legacy drawings/hand sketches into 3D parametric models, or generating STEP, IGES, DXF, and PDF exports.

Software & Tools:

Siemens NX

AutoCAD / DraftSight

Supported Export Formats: .prt, .step, .iges, .x_t (Parasolid), .dxf, .dwg, .pdf

Why Work With Me?

High precision and clean feature-tree management for easy future modifications.

Clear, prompt communication and reliable turnaround times.

Revisions included to ensure the output aligns with your manufacturing requirements.

Let’s discuss your project requirements—feel free to message me with your drawings or concepts to get started.

Profile Title: Siemens NX CAD Designer (3+ Years Experience) | 3D Modeling | 2D Drafting & Manufacturing Drawings

Overview / About Me:

I am a mechanical CAD designer with over 3 years of hands-on industry experience specializing in Siemens NX (Unigraphics). I help engineering firms, manufacturers, and product developers turn conceptual designs and rough sketches into production-ready 3D CAD models and detailed engineering drawings.

Having spent the last 3 years working on real-world engineering workflows, I understand that CAD design isn't just about making things look good—it's about manufacturability, tight tolerances, and functional assembly. I deliver clean, parametric designs that save time and eliminate errors on the shop floor.

Core Services:

3D CAD Modeling: High-precision parametric part design, complex assemblies, sheet metal design, and reverse engineering.

2D Technical Drafting: Complete shop drawings, fabrication plans, exploded views, section details, and structured Bills of Materials (BOM).

GD&T & Tolerance Stack-Up: Proper geometric tolerancing according to ASME/ISO standards to guarantee precise fit and function.

Legacy Data Conversion: Translating paper blueprints, hand sketches, and 2D DWG/DXF files into fully parametric 3D models.

Software & Export Capabilities:

Primary CAD: Siemens NX

Secondary Drafting: AutoCAD

Deliverable Formats: Native NX (.prt), Parasolid (.x_t), STEP (.step), IGES (.iges), AutoCAD (.dwg, .dxf), and PDF.

Why Work With Me?

3+ Years of Proven Design Discipline: Robust, editable feature trees designed for manufacturability (DFM).

Accuracy First: Focused on standard tolerance practices to avoid costly prototype iterations
