Mechanical Design Services, 3D CAD Modeling & Engineering Drawings
Mechanical product, machine, process-equipment and plant-design support—from concept development and 3D modeling to analysis inputs, fabrication drawings, bills of materials, reverse engineering and CAD migration.
Mechanical Engineering Documentation for Products, Machines and Industrial Equipment
Structural Drafting Group provides mechanical design, CAD modeling and engineering-drawing support for organizations developing products, machines, process equipment, packaged systems and industrial facilities.
The scope can begin with sketches, specifications, legacy drawings, scan data or an existing model and continue through conceptual layouts, parametric 3D models, detailed parts and assemblies, manufacturing drawings, bills of materials and controlled revisions.
From Product Concepts to Plant and Equipment Documentation
The legacy page’s principal mechanical-design topics are retained and reorganized into clear service categories.

Sheet-metal components, enclosures, architectural-metal products, weldments, frames and fabricated equipment drawings.
View Manufacturing DrawingsReverse Engineering & CAD Migration
Recreate, remodel or migrate mechanical parts and assemblies from legacy CAD, drawings, measurements, scans or images.
Review Migration ScopeConnect Functional Requirements with Geometry, Analysis and Production Data
A controlled workflow helps prevent disconnected models, incomplete drawings and manufacturing information that does not match the approved design.
Function, performance, envelope, loads, operating conditions, materials and connection points defined from approved inputs.
Alternative arrangements, component selection inputs, motion concepts, access and manufacturing approach explored.
Parametric parts, assemblies, interfaces, clearances and product structures developed in the selected CAD environment.
Analysis results, tolerances, manufacturability, maintainability and project requirements reviewed by responsible specialists.
Approved models translated into detailed drawings, BOMs, manufacturing data, manuals and controlled release packages.

Design Refinement, Analysis Inputs and Manufacturing Readiness
Engineering decisions and acceptance criteria remain with the responsible professionals; our team supports the modeling, documentation and controlled revision workflow.
Static & Dynamic Analysis Support
Prepare geometry, load-case documentation and model revisions for finite-element or other qualified engineering analysis.
Stress & Thermal Design Inputs
Coordinate approved pressure, temperature, load, material and boundary-condition information with equipment models and drawings.
GD&T and Tolerance Documentation
Apply approved datum schemes, geometric controls, fits and tolerance-stack information to manufacturing drawings.
Prototype and Manufacturing Support
Develop production drawings and model formats for approved prototyping, machining, forming, fabrication or additive-manufacturing processes.
Start with the Best Available Technical Information
The controlling specification, source hierarchy, calculation responsibility and expected output formats should be defined before design work begins.
INTypical Source Inputs
Mechanical design assignments can begin from conceptual information or developed engineering data.
OUTTypical Deliverables
Outputs are configured around the client’s design, engineering and production workflow.
A Controlled Workflow from Requirements to Released Documentation
The workflow is adapted to concept development, product redesign, equipment packages, reverse engineering, CAD migration or production-documentation assignments.
Requirements Review
Confirm function, inputs, interfaces, responsibilities, standards, formats and project milestones.
Concept & Planning
Develop the design approach, model structure, alternatives, assumptions and review strategy.
Modeling & Detailing
Create parts, assemblies, equipment layouts, drawings, tolerances and supporting design data.
Review & QA/QC
Check geometry, interfaces, consistency, manufacturability, source data and approved comments.
Release & Revisions
Issue controlled files and incorporate approved engineering, manufacturing or client changes.
Mechanical Design Support for Equipment, Products and Industrial Systems
The existing page’s industry coverage is retained while avoiding unsupported performance or certification claims.
Software Selected Around the Product, Equipment and Delivery Requirements
The legacy page lists a broad range of mechanical, plant and engineering tools. The actual platform should be confirmed for each project before work begins.
File compatibility, software version, model structure, naming standards and required neutral formats should be defined during project setup. Software use does not replace qualified engineering review.
Mechanical Design Support Connected to Drafting, Piping and MEP Documentation
Mechanical designs can be coordinated with fabrication drawings, piping systems, plant layouts and wider engineering-documentation requirements.
Support from requirements and layouts through detailed models, drawings, BOMs and controlled revisions.
Equipment, nozzles, skids, supports, routes and plant interfaces reviewed across related documents.
Templates, model structures, naming, dimensions, tolerances, layers and file formats aligned to requirements.
Capacity for individual components, complex assemblies, complete equipment packages and ongoing workloads.
