Revolutionary CAD-to-3D technology launched – Metrology and Quality News

Nextech AR Solutions Corp. (“Nextech”), a leading diversified provider of Augmented Reality (“AR”) experience technologies and services, announced the launch of its revolutionary CAD to POLY solution. The Company now integrates into its services technology to create optimized 3D meshes suitable for 3D and AR applications. Due to the fact that the global CAD market is dominated by large manufacturers of; automotive, aerospace, industrial machinery, civil engineering and construction, electrical and electronics, pharmaceuticals, healthcare, consumer goods and others, the company believes this technology will gives the advantage of being the first in the market (according to BIS Research) of 11 billion Canadian dollars. and expands its augmented reality business beyond e-commerce.

The Company has filed a provisional patent covering the conversion of CAD files into 3D models. The ability to convert CAD models to 3D means significantly improved scalability associated with Nextech’s 3D models for e-commerce, with the creation of photorealistic, fully textured 3D models from raw CAD models and reference images.

CEO Evan Gappelberg commented on the technology, “Most modern products ever built were made from reference CAD models. Think about it, there are billions of products in the world, and Nextech has invented a simple way to turn them into 3D models. Instead of using 2D images to create 3D models, we now have the ability to go directly to the source, where the products are actually designed by engineers (CAD files) and turn them into perfect 3D models, at large scale. Our new CAD to POLY solution is built on technology that will prove to be the holy grail of scaling 3D content.

Currently, CAD is a function of product engineering. Industrial designers, working for product manufacturers, use CAD software (eg, AutoCAD, SolidWorks, etc.) to design many products in the modern world. To use these CAD files for commercial purposes, one must convert the CAD file into a 3D model which is a digital replica of the physical product.

Nima Sarshar, CTO of Nextech AR, commented on issues with meshes natively exported from CAD, “Nextech solved all these problems by redesigning the process of converting CAD files to 3D meshes from scratch. Rather than relying on native CAD conversion, we created CAD conversion technology from the ground up, creating new techniques rooted in computational geometry, computer vision, and physics. When given a CAD file, we can now create fully textured, light-to-scale 3D models that can be used for real-time AR and 3D visualization.

Computer generated imagery requires 3D meshes

Although highly desirable for manufacturing design, this poses a problem when the same 3D CAD drawings are going to be used for computer generated imagery (CGI). 3D CGI is almost exclusively based on the concept of tessellated surfaces (which are hollow, not solid). In fact, there is no concept of a solid in most CGI design tools; everything is surface. Additionally, renderers that render 3D CGI objects require tessellated meshes for raycasting and shading optimization. This is how almost all 3D modeling and rendering software works. Therefore, in order to use a CAD design for CGI purposes (for example, to allow customers to view the product in 3D on their mobile or desktop websites), a 3D CAD model must be translated into a polygonal mesh. This global operation is called CAD to POLY or C2P. A detailed overview of the process can be read at Automatically transform 3D CAD designs into CGI-ready 3D models
