Our 3D Part Modeling Services
DevWorks 3D part modeling services cover the full path from a single parametric part to a released assembly: solid and surface modeling, assembly fit checks, GD&T, manufacturability review and file delivery in the formats your suppliers use.
Parametric Part Modeling
History-based, fully constrained solid models where every feature is driven by dimensions and design intent. When a key dimension changes, dependent features update with it, so revisions and part variants never require remodeling from scratch.
Surface & Complex Geometry
Advanced surface modeling for organic forms, Class-A surfaces and complex blends that solid tools cannot capture alone. Surface and solid features are combined in one model, so curved housings, grips and molded covers stay editable and ready for tooling.
Assembly Integration
Multi-part assemblies built with mates, interference checks and motion studies to confirm that parts fit and move as intended. The assembly structure is set up for clean BOM extraction and manufacturing documentation.
GD&T & Tolerance Analysis
Fully toleranced models and drawings per ASME Y14.5 / ISO 1101 with datum reference frames and stack-up validation. Tolerances are applied to the functional features that control fit, so suppliers know exactly which dimensions matter at inspection.
Manufacturing-Ready Models
Models built for the process that will make the part, including CNC machining, injection molding, sheet metal, casting and additive manufacturing. Draft angles, wall thickness, bend radii and tool access are checked for manufacturability (DFM) before release.
Neutral File Delivery
Native CAD files plus STEP, IGES, Parasolid and JT exports. Native files keep the full feature history for future edits, while neutral formats let suppliers and tooling partners open the geometry in their own CAD systems.
How Our 3D Part Modeling Process Works
Our 3D part modeling process runs in six stages, each with a clear deliverable and a review point, so you approve the model before it is released to manufacturing.
01
Input Review & Scoping
We review your sketches, product requirements or physical sample parts and confirm material, manufacturing process, tolerances and output formats.
DELIVERABLE: Confirmed scope and modeling plan
02
Design Intent Planning
We decide which dimensions drive the part, where datums sit and how features are ordered, so the model updates predictably when values change.
DELIVERABLE: Modeling strategy and datum scheme
03
Parametric Modeling
Fully constrained, dimension-driven solid and surface modeling in the CAD platform your team uses.
DELIVERABLE: Native parametric part model
04
Assembly & Fit Checks
Parts are placed in assembly context with mates, interference checks and motion studies to confirm fit and function.
DELIVERABLE: Validated assembly model
05
GD&T & DFM Validation
Tolerances are applied per ASME Y14.5 / ISO 1101 and the model is checked against the target process, such as CNC machining, molding, sheet metal, casting or additive.
DELIVERABLE: Toleranced, DFM-checked model
06
Release & File Delivery
Final models are released in native CAD plus STEP, IGES, Parasolid or JT, with drawings where required.
DELIVERABLE: Native and neutral CAD files

3D Part Modeling FAQs
3D part modeling services create accurate, editable CAD models of individual components from sketches, requirements or physical samples. DevWorks builds these models parametric and fully constrained, so they are ready for manufacturing and easy to revise.
A sketch, a list of product requirements or a physical sample part is enough to start. Tell us the material, manufacturing process and file formats you need, and we confirm the scope before modeling begins.
We model in SOLIDWORKS, Autodesk Inventor and Solid Edge, and deliver native files in the platform your team uses.
You receive native CAD files plus neutral exports in STEP, IGES, Parasolid or JT, so suppliers and tooling partners can open the geometry in their own CAD systems.
Yes. Every model is checked for manufacturability against the target process, such as CNC machining, injection molding, sheet metal, casting or additive, and can include GD&T per ASME Y14.5 / ISO 1101.
A parametric model stores design intent, so changing one driving dimension updates every dependent feature automatically. Revisions and new part variants take far less time than remodeling, and the same model can later support CAD design automation.
