3D CAD Modeling Services

3D CAD modeling is the creation of three-dimensional digital models of parts, assemblies, and components using solid and surface modeling. Built from 2D drawings, sketches, or reference geometry, these models support visualization, engineering, and fabrication, and export to native and neutral formats such as STEP, IGES, and STL.

Product teams, fabricators, and designers frequently need 2D drawings, concept sketches, or physical references turned into clean, accurate 3D geometry. Our 3D CAD modeling service builds parametric solid models and freeform surface models of individual parts, multi-part assemblies, and building components, distinct from full BIM authoring. We model in SolidWorks, Inventor, Rhino, Fusion 360, and AutoCAD 3D, structuring feature trees and assemblies so the model stays editable and ready for downstream visualization, analysis, or manufacturing.

With 400+ delivered BIM/VDC projects for clients across the US, UK, and Europe, we model to your CAD standards, naming conventions, and templates and work in imperial units by default with metric supported. Whether you need a single detailed part, an assembly with mates and a bill of materials, or components prepared for rendering or fabrication, we keep geometry watertight and dimensionally correct. We export STEP, IGES, STL, and native files, and sign an NDA on request before you share your designs.

Why Outsource 3D CAD Modeling to Powerkh

Solid and surface expertise

Parametric solids for engineering and fabrication plus freeform surfaces for organic and product shapes, chosen to fit each part.

From any reference

We model from 2D drawings, hand sketches, photos, or existing geometry and turn them into accurate, editable 3D CAD models.

Manufacturing-ready geometry

Watertight, dimensionally correct models with clean feature trees and assemblies, exported to STEP, IGES, STL, and native formats.

Flexible, predictable engagement

Hourly pricing with a free quote and payment only after delivery, plus an English-speaking team reachable 8:00-18:00 UTC+2 on weekdays.

Our 3D CAD Modeling Services

Part modeling

Detailed parametric solid models of individual parts with clean, editable feature trees built to your dimensions and standards.

Assembly modeling

Multi-part assemblies with proper mates, constraints, and structure, plus bills of materials and exploded views where needed.

Surface modeling

Freeform and organic surface models for product, enclosure, and stylized shapes where pure solid modeling is not enough.

Building components

Standalone 3D models of facade elements, connections, fittings, and fabricated components for visualization or manufacturing.

2D to 3D conversion

Turning 2D drawings, sketches, or reference images into accurate 3D CAD geometry ready for downstream engineering and production.

Models for render and fabrication

Geometry prepared for photorealistic rendering, 3D printing, or CNC and other fabrication, exported to the formats you require.

Our 3D CAD Modeling Process

  1. Share inputs and requirements

    Send your drawings, sketches, or reference images with target software, units, and output formats. We return a free quote.

  2. Agree modeling approach

    We confirm solid or surface strategy, level of detail, assembly structure, and naming so the model fits your downstream use.

  3. Build the model

    We model parts and assemblies with clean feature trees and mates, keeping geometry watertight and dimensionally accurate.

  4. Check and validate

    Models are reviewed for accuracy, interferences, and manufacturability, and checked against your inputs before delivery.

  5. Export and deliver

    We deliver native files plus STEP, IGES, STL, or other neutral formats you need, and incorporate any revisions you request.

Software We Use

We model in the leading 3D CAD platforms and export to the native and neutral formats your workflow depends on.

  • AutoCAD 3D
  • SolidWorks
  • Inventor
  • Rhino
  • Fusion 360

FAQ

What does your 3D CAD modeling service include?

Solid and surface modeling of parts, assemblies, and building components from 2D drawings, sketches, or reference geometry. We build editable feature trees and structured assemblies for visualization, engineering, and fabrication, and deliver native files plus neutral formats such as STEP, IGES, and STL.

How is this different from BIM modeling?

This service produces standalone 3D CAD geometry for parts, products, and individual components, not data-rich building information models. If you need Revit-based BIM authoring for whole buildings, that is handled by our BIM services; here the focus is manufacturable and presentable 3D geometry.

Can you model from 2D drawings or sketches?

Yes. We build accurate 3D models from 2D drawings, hand sketches, photographs, or existing 3D files. We confirm critical dimensions, tolerances, and intent up front, and flag any conflicts we find in the source material before finalizing the geometry.

Which software and export formats do you support?

We model in SolidWorks, Inventor, Rhino, Fusion 360, and AutoCAD 3D, working in imperial by default and supporting metric. We export native files plus STEP, IGES, STL, and other neutral formats so the model drops straight into your rendering, analysis, or fabrication pipeline.

How do you price 3D CAD modeling projects?

We charge hourly and provide a free quote after reviewing your inputs, part count, and required detail and formats, and payment is due only after the work is delivered. An NDA is available on request before you share any designs.
