CAD Design & 2D/3D Drafting Services
CAD Design Services & Manufacturing Grade Drafting.
Precision 3D parametric modeling, drafting conversions, and manufacturing drawings with standardized dimensioning and tolerancing.
CAD Design & 2D/3D Drafting: Scope & Deliverables
Precision hardware production relies on unambiguous engineering documentation. WENS Engineering provides disciplined CAD design services, mechanical 3D modeling, and production drafting. We convert legacy 2D drawings into parametric 3D CAD models, build mechanical assemblies, generate manufacturing drawings with Geometric Dimensioning & Tolerancing (GD&T), and establish structured BOMs ready for CNC machining, fabrication, or tooling. Our outsourced CAD drafting support includes SolidWorks mechanical design, assembly detailing, sheet metal drawings, and 2D-to-3D conversion. Native file formats and drawing standards are agreed before release so your engineers and suppliers can use the deliverables.
Core Engineering Capabilities:
Problems This Service Solves
- Incomplete or ambiguous production drawings causing shop-floor manufacturing errors.
- Outdated legacy 2D drawings that do not match current physical tooling or parts.
- Supplier disputes over inspection criteria due to lack of defined datum schemes and GD&T.
- Engineering bandwidth bottlenecks during drawing release phases.
Our Technical Process
A clear, phased workflow with verification gates at each step.
Data Audit
Review supplied sketches, scan data, legacy prints, or CAD models to establish datum strategies.
Parametric Modeling
Construct fully constrained native parametric geometry adhering to client modeling standards.
Drafting & Detailing
Generate projection views, cross-sections, detail views, and apply exact GD&T tolerances.
Quality Check & Sign-off
Perform peer review verifying interference checks, revision blocks, and dimensional integrity.
Standard Project Deliverables
You receive fully documented, revision controlled engineering assets ready for fabrication or your internal engineering systems.
Frequently Asked Questions
What are CAD design services?
CAD design services encompass the creation, modification, and digital modeling of physical parts and mechanical assemblies using parametric computer-aided design software. WENS Engineering delivers high precision 3D solid models, assembly structures, and standardized 2D manufacturing drawings with standardized Geometric Dimensioning & Tolerancing (GD&T) conventions for production machining, fabrication, or tooling.
What is the difference between 2D drafting and 3D CAD modeling?
3D CAD modeling constructs a full volumetric digital representation of a component, allowing interference checks, mass calculation, and direct export to CAM machining. 2D drafting translates that 3D model into detailed manufacturing prints with orthographic projections, datum reference frames, GD&T feature control frames, and surface finish callouts required by machine shops.
Why is GD&T essential in manufacturing drawings?
Geometric Dimensioning and Tolerancing (GD&T) establishes an unambiguous mathematical language defining feature locations, orientations, and forms relative to functional datums. Unlike coordinate plus-minus tolerancing, GD&T prevents supplier measurement disputes, provides bonus tolerance under Maximum Material Condition (MMC), and ensures mating components assemble seamlessly on the factory floor.
Can WENS convert legacy 2D drawings into parametric 3D CAD models?
Yes. WENS Engineering regularly digitizes legacy paper prints, scanned PDFs, and 2D DXF/DWG files into fully parametric native 3D CAD models. Our engineers verify dimensional consistency, resolve legacy drafting discrepancies, and generate parametric feature trees aligned with your internal CAD standards and revision controls.
What should I send for a CAD drafting quotation?
Send the sketches, existing CAD or drawings, number of parts and assemblies, required native CAD format, drawing standard, and target deadline. Identify whether you need new mechanical design, drawing cleanup, or a complete manufacturing drawing package.
