Ultra-precise, 3D Measuring to Reconstruct an Object into a 3D CAD Model

Our reverse engineering services are industry leading, but what does it take to build a 3D CAD model?

Step 1 – Measurement/Gathering Data

There are several methods that can be utilized for data extraction.

Some of these include:

  • CMM
  • Video measurement systems
  • Laser scanners

As the industry evolves, other cutting edge, extremely accurate systems are emerging. Industrial CT scanning and blue light scanning are two such technologies Nel PreTech has mastered.

Step 2 – Data Processing

This is typically a preprocessing step to get ready for the third step of creating a 3D CAD model. For others, this may be the final step. For customers interested in data analysis, or rapid prototyping with their own internal CAD department, this step may be all that is needed.

The raw data from step 1 is processed and used to create a polygonal .STL model. For those customers who require a solid .STEP conversion of the .STL data set, further mesh editing/processing of the .STL may be needed.

Step 3 – CAD Model Creation

Rapid Surfacing/quick-wrap method: As mentioned in step 2, the option to convert the polygonal .STL file to a solid .STEP file is available. This is typically the least costly and fastest method of creating a CAD model.

Our reverse engineering software takes the STL model from the previous step and shrink wraps a surface over the entire STL model. The result is a completely surfaced model that matches the scanned part exactly. All imperfections such as warp, parting lines, flash, etc. are captured.

The surfaced model can then be exported in an IGES or STEP format for further processing in other CAD software packages. This method produces a solid model that is a simple solid conversion of the polygonal .STL file. No parametric information is contained in the file.

Parametric CAD modeling

Data from step 1 and step 2 can be combined and used as design templates to rebuild a parametric model from scratch.

  • These parts contain geometrically perfect surfaces
  • They can be exported in a .STEP or .IGES format.

Fully parametric models can also be produced and provided in a native Solidworks format.

  • Models provided in this way contain all design tree information and can be edited within Solidworks.
  • These types of files are best suited for parts that are being re-designed or going through several different design iterations.
  • These files can also be used to generate blueprints within Solidworks.

3D Scanning for Reverse Engineering

3d scanning is a technology used to collect a 3d data set of an object or part. The digitization process captures the exact size and shape of a part without need for cutting or destruction. The data is then used to construct a 3d model.
  • Surface variations can be analyzed with user-definable color patterns.
  • Cross sections give the ability to see otherwise hidden features.
  • Materials of different densities and surface finishes are a good fit for 3d scanning as well.

There are a variety of technologies used to acquire x, y, z coordinates of a real-world object. If you choose to work with Nel PreTech, you’ll find we employ the newest 3d scanning technologies. Talk to our experts to find the appropriate fit for your 3D scan to cad application.

  • Legal certification for compliance & protection to our clients
  • Deep understanding & management of measurement uncertainty
  • Quality assurance

Post-Scan Processing

  • The removal of errors from the mesh created by erroneous points or “noise” from the point cloud.
  • Gaps or irregularities in the mesh can also be detected and healed. This is the most important & time-consuming step in the surface wrapping process.
  • It is crucial to remove or fix all errors prior to surfacing to ensure that the final model does not contain undesirable irregularities or surface anomalies.
  • The model must also be water-tight or “manifold” before surfacing.

Creating a Parametric Model

  • An .stl file is generated from the raw scan data.
  • The next step in the process is mesh editing. Mesh editing is not as crucial to the parametric modeling process as it is for a surface wrap.The mesh just needs to be clean enough to extract dimensional data for feature modeling.
  • Dimensions are extracted from the scan & parametric features are created
  • The result is a fully parametric solid model with feature design history that can be transferred over to most major CAD packages for further design editing or incorporation into an assembly.
  • The model can also be exported in a STEP or IGES format.
  • Using the accuracy analyzer allows the user to see areas of deviation. This is useful for finding areas that may need to be further processed or to expose areas where the original part may be worn.

3D Scanning Output Options

Getting to know the customer, the part, and intended use of the 3d scan data we provide helps us determine the best delivery method for your objectives. To learn more about our 3d scanning deliverables read: Engineered Formats & Outputs for 3D Scanning Services.

Four Key Outputs:

  1. Raw data: A cloud of points. Sometimes a company may want this data for archival purposes or to test a tool over time to see if there is any wear.
  2. STL file: Polygon mesh
  3. Surface Wrap: Exact and true representation of the part “as is” in a .step file.
  4. Parametric Model: Builds perfect surfaces on top of an imperfect part or scan data.
