Do you have prototypes, current products, or finished tooling, but no related drawings or CAD data? Are you dreading having to create the CAD model from scratch?
Or do you design highly customisable products such as medical devices that require a perfect fit with the human body.
Creo Reverse Engineering Extension (REX), allows you to easily create the 3D CAD model of your physical product.
Whether you are reverse engineering from a complex clay model, or from a scanned engineered mounting plate, Creo Reverse Engineering will enable you to get it right the first time.
Work with ‘point cloud’ data obtained by scanning physical prototypes.
With Creo Reverse Engineering, you are able to capture valuable data without having the original CAD files. The above image shows the resulting facet model from a scanned point cloud of a hip bone. Verification tools ensure that the resulting CAD model accurately represents the scanned data.
- The Steps
-
With these cutting edge tools, you can refine the point cloud and polygonal data, reducing noise and/or the total number of points. In this way you can speed up processing time, without sacrificing the level of detail, all while preserving original design intent.
From there the steps are:
- Create an acceptable facet model
- Next, surfaces can be projected to fit facet data or boundary surfaces created from curves sketched on the facet model.
- Or use the geometric surface options such as planar, cylindrical, extruded or revolved surfaces.
- Creo Reverse Engineering captures physical characteristics such as surface tangency, ensuring that the design intent is preserved 100%.
You can recreate the CAD data for a product for mass-production, or re-use the information for highly customisable products. Creo Reverse Engineering gives you the power to design new, more innovative products that will win in today’s competitive environment.
Dynamic facet modelling
- Key Benefits
-
- Reduce costs and shorten development time by automating the process of reverse engineering a physical prototype
- Simplify the workflow, and minimise the learning curve, by using the same CAD program you use to design your products to also reverse engineer a product
- Reduce noise in point cloud data for more accurate product designs
- Maintain design integrity by accurately capturing the design intent of the original product
- Automate the manual process of transforming scan data into manufacturable surfaces
- Easily update old designs without their original digital data to meet new market requirements
- Analyse the differences between the completed model and the original point cloud data to verify accuracy
