CAD Design From Concept Sketches to Manufacturing-Ready Drawings
Every manufactured product starts as a CAD file. The precision of that file determines whether the first prototype fits together, whether the toolmaker can produce it, and whether your manufacturing partner can quote it accurately. Rough CAD means expensive iterations. Precise CAD means first-article approval on the first try. We deliver production-ready CAD in SolidWorks, AutoCAD, and ArchiCAD with proper tolerancing, materials specification, and manufacturing annotations — files that your toolmaker or fabricator can use directly without interpretation.
The Cost of Imprecise CAD Files
A missing tolerance on a mating surface costs a $15,000 injection mold revision. An incorrect thread specification means 500 machined parts that don't fit. A wall thickness below the minimum for the chosen material means the part warps or breaks after molding.
These aren't theoretical risks — they're the daily reality of manufacturing. And they almost always trace back to CAD files that were modeled for appearance rather than production. A 3D model that looks correct on screen can be fundamentally unbuildable: zero-radius internal corners that concentrate stress, draft angles insufficient for mold release, or assembly interference that only becomes apparent when physical parts meet.
Production-ready CAD requires manufacturing knowledge embedded in the design. Draft angles for injection molding. Fillet radii for CNC machining. Tolerance stackup analysis for multi-part assemblies. Material-specific wall thickness minimums. Fastener specification with torque requirements. These details turn a 3D model into a manufacturing document.
CAD Design Services

Assembly Design
Multi-part assemblies with interference checking, BOM generation, and exploded view drawings. Mechanism simulation for moving parts.
Product Development
Concept-to-production pipeline: industrial design, engineering, prototyping support, and manufacturing documentation. DFM (Design for Manufacturing) included.
Architectural Drafting
Floor plans, sections, elevations, and detail drawings. BIM models in ArchiCAD or Revit for coordination with structural, MEP, and interior design.
Reverse Engineering
Create CAD models from physical parts using 3D scanning data, measurements, or photographs. Recreate legacy parts without original documentation.
2D Technical Drawings
Manufacturing drawings with dimensions, tolerances, surface finishes, and notes per ASME Y14.5 or ISO standards. Shop-floor-ready documentation.
Our CAD Design Process
Requirements & Specifications(2-5 days)
Define functional requirements, dimensional constraints, material selection, manufacturing method, and tolerance requirements. Review existing sketches, samples, or reference designs.
Concept Modeling(3-10 days)
Create initial 3D CAD model with key dimensions and features. Verify form, fit, and function with the client. For assemblies, check clearances and motion range at this stage.
Detail Design & DFM(5-15 days)
Add manufacturing details: tolerances, draft angles, fillets, surface finishes, and material callouts. Design for Manufacturing review ensures the part can be produced cost-effectively.
Documentation & Delivery(3-5 days)
Generate 2D manufacturing drawings, assembly instructions, and BOM. Export in native format plus STEP/IGES for universal compatibility. Include revision history and design intent documentation.

CAD Design by Industry
Consumer Product
Challenge: Startup needs a kitchen appliance designed for injection molding — from napkin sketch to manufacturing-ready CAD in 8 weeks
Solution: Full product development: industrial design, SolidWorks modeling, DFM optimization for injection molding, tolerance stackup, and manufacturing drawing package
Result: First mold articles approved with one minor revision. Product launched 2 months ahead of competitors who were still iterating prototypes.
Industrial Equipment
Challenge: Manufacturer needs to redesign a legacy machine component — original drawings lost, only a worn physical part remains
Solution: 3D scanning of physical part, reverse engineering in SolidWorks, dimensional improvement based on wear patterns, and updated manufacturing drawings
Result: New parts produced within ±0.05mm of specification. Redesign addressed the wear failure mode, extending part life by 3x.
Architecture
Challenge: Architecture firm needs ArchiCAD BIM models for a 12-unit residential project with structural coordination
Solution: Complete BIM model in ArchiCAD: architectural plans, sections, elevations, door/window schedules, and IFC export for structural engineer coordination
Result: Zero clashes detected during construction. BIM coordination identified 23 potential conflicts in design phase — resolved before breaking ground.

Frequently Asked Questions
How much does CAD design cost?
Simple part drawings: $200-$500. Mechanical assemblies with BOM: $1,000-$5,000. Full product development (concept to manufacturing drawings): $3,000-$15,000. Architectural plans: $500-$2,000 per drawing. Hourly rate for ongoing CAD work: $60-$120/hour. We provide fixed-price quotes for defined-scope projects and hourly rates for ongoing or evolving work.
Which CAD software should I use?
Mechanical/product design: SolidWorks (industry standard) or Fusion 360 (cloud, lower cost). Architecture: ArchiCAD (Mac-friendly BIM) or Revit (Autodesk ecosystem). 2D drafting: AutoCAD. Aerospace/automotive surfacing: CATIA or Siemens NX. We recommend based on your industry, team capabilities, and what your manufacturing partners or contractors can receive.
Can you work with my existing CAD files?
Yes — we work with native files from SolidWorks, AutoCAD, ArchiCAD, Revit, Fusion 360, Inventor, CATIA, NX, Creo, and Rhino. We also import neutral formats: STEP, IGES, DXF, DWG, and SAT. If you have files in a format we haven't listed, we can almost certainly convert and work with them.
Do you provide prototyping support?
We prepare files optimized for your prototyping method: STL/3MF for 3D printing (FDM, SLA, SLS), DXF for laser cutting, STEP for CNC machining, and complete drawing packages for sheet metal fabrication. We can recommend prototyping vendors and review first-article samples against the design intent.
What is DFM and why does it matter?
Design for Manufacturing (DFM) is the practice of designing parts so they can be produced efficiently. For injection molding: draft angles, wall thickness, gate location, and shrinkage compensation. For CNC: tool access, fixture planning, and radius constraints. For sheet metal: bend radii, hole-to-edge distances, and grain direction. DFM review during design prevents expensive tooling revisions — a single mold modification can cost $5,000-$20,000.
How do you handle revisions?
Every CAD project includes 2-3 revision rounds. We use parametric modeling — dimensions and features are linked, so changing one dimension automatically updates all dependent geometry. This makes revisions efficient rather than requiring rebuilds. Revision history is documented with change descriptions, and we maintain version control so any previous state can be recovered.
