Here’s a riddle for you. How do you know if two versions of a CAD file that appear visually the same are the same? The truth is, often you don’t.
Kubotek USA is aiming for a different answer. The Marlborough, MA , company has released the Kubotek Validation Tool, a product designed to assure manufacturers that two CAD models that visually appear the same truly are geometrically identical. Kubotek is aiming to help solve a common problem: Changes in the definition of a 3D model can happen anywhere in the process—either amongst the internal development team or within the supply chain. These changes can be concealed and imbedded in the 3D CAD data and if undetected, can cause disastrous errors resulting from unintentional edits or translation errors when a model is passed between engineering groups. The Kubotek Validation Tool tests the 3D model and generates reports, including a simple pass-fall indicator, a tamper-proof validation certificate and a detailed listing of any differences found.
The software works with models from all the major CAD systems without requiring any CAD licenses. Kubotek claims its approach is better suited as a comparison tool for solid models coming from multiple CAD programs. Instead of Boolean differencing or measuring point deviations, which other similar programs employ, the company uses Kubotek’s Face Logic technology to analyze the geometric data types found in solid models based on a specified tolerance. Additional tests compare mass properties results and count geometry and topology.
We looked at a number of sources to determine this year's greenest cars, from KBB to automotive trade magazines to environmental organizations. These 14 cars emerged as being great at either stretching fuel or reducing carbon footprint.
Researchers at MIT and Sandia National Labs have observed a reaction in lithium-air batteries that could help improve the design of these cells for electric vehicles and other applications.
Healthcare might seem to be an unlikely target application for the Internet of Things technology, but recent developments show small ways that big-data is going to make an impact on patient care moving into the future.
As energy efficiency becomes more and more a concern for makers of electronics devices, researchers are coming up with new ways to harvest energy from sound vibration, footsteps, and even electromagnetic fields in the air.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
