XOR makes editable CAD models from 3D scan data.
Rapidform XOR/Redesign is the first software solution that allows users to go from 3D scan data to a fully parametric CAD model. While traditional 3D scan data processing software has focused solely on optimizing polygon mesh models or generating high quality NURBS surfaces from 3D scan data, the needs of those who require editable CAD solid/surface models from 3D scan data have been largely ignored. Rapidform XOR addresses the limitations of existing 3D scan data processing software by complementing its mesh modeling and NURBS surfacing capabilities with newly developed CAD modeling capabilities, providing users with the tools to go from 3D scan data to a parametric CAD model. Before the development of Rapidform XOR, those who wanted to make design modifications to their reverse engineered models in their CAD applications were forced to:

1. Export an un-editable, "dumb" surface model that was difficult to edit
2. Recreate a parametric CAD model through a variety of workarounds which require multiple software applications and do not ensure accuracy

Creating a parametric CAD model from 3D scan data allows users to fully realize the value of 3D scanning. Rapidform XOR features a set of tools designed specifically to address the unique requirements of reverse engineering, ensuring that the final redesigned model is built within user-defined tolerances.

 

Rapidform XOR/Redesign employs a completely new approach to reverse engineering and processing 3D scan data. Rather than simply improving the existing methods of creating static models from 3D scan data, Rapidform XOR empowers users to create parametric CAD models from 3D scan data while utilizing the design process and user interface of popular CAD applications. Rapidform XOR is easy to learn for anyone familiar with 3D CAD, and is by far the fastest way to go from raw 3D scans to finished CAD models. XOR's patented Accuracy Analyzer shows real time deviation analysis results while a part is being modeled. The tool ensures the accuracy of the final model while saving modeling time by integrating the inspection tool within the design process, which eliminates the time consuming cycle of checking modeling accuracy in a separate software, modifying the model to correct the undesirable deviation, and repeating that process until the final part is redesigned within an allowable tolerance.
While the main differentiator of Rapidform XOR remains its ability to create parametric CAD models from 3D scan data, Rapidform XOR is a comprehensive software solution that also provides users with the tools to create an optimized polygon mesh model or high quality NURBS surface model that can be used for rapid prototyping, analysis, simulation and machining. The polygon optimization and NURBS surfacing tools are also important tools that can be integrated with the CAD modeling capabilities of Rapidform XOR for the creation of CAD solid/surface models that contain freeform features.

The design process and user interface in Rapidform XOR/Redesign have been developed to be instantly familiar to users of popular CAD applications, leading to incredible time savings over traditional reverse engineering software while simultaneously creating output in the form of parametric CAD solid models. Time savings can be realized through:

Because the interface and design process of Rapidform XOR were developed to be similar to popular CAD applications, users can utilize their existing CAD modeling skills to immediately begin designing in Rapidform XOR. Internal benchmarking tests have shown a time savings of up to 80% when using Rapidform XOR over the traditional surface fitting methods in great part because the design process removes the need to clean the scan data of a part. A complete scan of a part is unnecessary provided there is enough data to recognize design parameters.
 

CAD models are the industry standard for communicating design parameters and manufacturing requirements. Reverse engineering 3D scan data to a parametric CAD model can be useful for a variety of applications including benchmarking, creating a CAD model for a part that lacks documentation, or for creating a CAD model from a clay model. Once the 3D scan data of a part has been modeled in Rapidform XOR, a fully parametric CAD model with modeling history can be exported and modified in a variety of CAD applications including SolidWorks, Pro/Engineer and UG NX. From the user perspective, it will be as if the model had originally been designed from scratch in CAD.

 

CAD local redesigning and CAD-to-Scan refitting feature is an unprecedented tool to compensate the gap between an original CAD model and an actual part when you already have a CAD model but its real-life counterpart has been modified manually. In this case, Rapidform XOR automatically refits the original geometries of the existing CAD model onto the digitalized as-built mesh model and then optimizes them with preserving the original geometric information such as continuity and surface parameters. The innovative one-button CAD Correct™ and redesign feature enables users, like stamping-die designers, to easily correct their CAD model to reflect hand-made modifications. Manufacturing companies today are facing increasing pressures to reduce tooling times and costs. With this CAD-to-Scan refitting feature automating the tool duplication process, Rapidform XOR helps manufacturers effectively outpace the competition.

 

While generating a NURBS surface model is very useful for creating an exact digital representation of the 3D scan data of a part, it is also limited in the modifications that can be made to the model. Rapidform XOR can create an idealized CAD model from 3D scan data that can identify and define design parameters. With Rapidform XOR, a fillet can be represented as a fillet with a defined radius rather than a rounded edge in a static surface model.
