3D CAD Modeling Services
Professional 3D CAD Modeling to help you overcome product designs and manufacturing challenges.
Although 2D/3D CAD modeling is certainly not new, when combined with precision 3D scanning, the use of this technology has become more prominent throughout product development and manufacturing. Through CAD modeling, designs with complex and organic shapes can be brought from the physical into a variety of CAD software for different prototyping and manufacturing purposes.
Key Applications of 3D CAD Modeling Services:
Validate Prototypes and Products for Faster Approval
Translating the prototype to CAD through 3D scanning eliminates the re-work, increased cost, and time to market from hand measurement. In CAD software such as Geomagic Design X, quick iterative changes can be made to your designs in the 3D CAD model to refine early prototypes, such as shaping, surfacing, and creating high-quality symmetric 3D models. While your prototypes meet ever-increasing quality standards, the approval process will also sped up.
Resolve Quality Issues and Prevent Downtime
In quality inspection, visual deviation color maps or NURB models tell the difference between the built tool and the idealized CAD model. The inspection allows 3D experts to identify the defects and perform root-cause analysis to prevent downtime.

Which 3D CAD Model Works Best for You?
At Applied Precision 3D, CAD models are created from high quality 3D “point cloud” data from 3D scanning. This process is known as “reverse engineering.” Depending on the requirements, we provide you with the right CAD model from a wide range of data formats, including:
NURBs Surface
NURBS, Non-Uniform Rational B-Splines, uses basis splines to represent complex and organic geometry. As opposed to Polygonal Mesh, NURBs is a curve modeling. NURBs models are most used for FEA analysis and precisely capture fine tuning of mold and die surfaces including hand modifications.
Polygonal Mesh (STL)
A data structure, which is usually a post-processing of the cloud of points from scanning, to create a connectivity network between the points, forming a triangle mesh which includes the normal direction of the data. During this process, sub-processes such as filtering and data reduction can be performed. The most commonly used polygon mesh format is STL, which is also the same format often used in 3D printing as an input.
‘Classic’ 3D Model
The creation of CAD data to a high standard, such that it cannot be distinguished (in terms of quality of surfaces) from original design data. The resulting data (typically IGES, STEP, or others) will have the highest fidelity or usefulness for down-stream users.
‘Hybrid’ 3D Model
Combines a mixture of ‘classical’ and ‘rapid’ surfacing(software can assist in varying degrees on how the surface patch structure is created). Typically complex and organic surface geometry is ‘rapid’ surfaced, while geometric features or areas of anticipated change are classically surfaced to allow the highest fidelity in these areas.
