CAD-CAM-CAE

GrabCAD is a CAD collaboration platform where members share many highly detailed 3D models in several formats, either CAD-based (IGES; Step, etc.) and polygonal (OBJ, 3DS, etc.)

Understanding the history of a particular software and why it was created in the first place can be exciting and insightful, especially for those who are interested in or are currently using the software. Not only is the vision and idea behind the creation important but also the driving forces, the people behind it, and […]

Master techniques from top automotive designers and world-class game developers with this insider’s guide to designing and modeling 3D vehicles. With techniques demonstrated in 3ds Max, Maya, XSI, and Photoshop, 3D Automotive Modeling starts with a fantastic series of hot concept designs and continues […]

An increasinq number of projects in in the automotive and aeronautical industry include Class-A surface quality as a competitive advantage. Quality control tends to be too subjective, however, as it is usually entrusted to human inspectors. Optical systems are showing qreat a promise with theis high resolution, but the relevance, geometrical correctness and correlation with […]

McLaren, the Formula One racing group that is attempting to flex its muscles in road cars, vows to build machines that will leave the likes of Ferrari, Porsche and Aston Martin in the dust. And this requires the company to move faster than its rivals to adopt the latest advancements in computer graphics technology for […]

This paper presents two geometric operations–constrained curve beautification and polygonal mesh scissoring–for a sketch-based Computer-Aided Design (CAD) tool for the configuration design of automobile instrument panels. Using the proposed sketch- based CAD, industrial designers and mechanical engineers can work together closely to perform the early-stage configuration design efficiently by drawing candidate sub- panel boundaries on […]

In the last decades the competition in the automotive market, in all segments, has become very strong. This motivation has pushed all OEM (Original Equipment Manufacturers) to develop complex and high technical products, with more and more variants, that satisfy the increasing customer requirements on style, quality, safety, comfort and environmental protection. OEM have tried […]

Maximizing fuel efficiency of a vehicle is one of the prime areas of focus in the highly competitive automotive industry which requires development of efficient and optimized vehicle designs. External aero analysis using Computational Fluid Dynamic (CFD) techniques is widely used in the accurate estimation of an automotive vehicle’s drag coefficient, often critical in determining […]

Along with the variation of the market circumstance, the automotive industry has to be confronted with various challenges. In order to satisfy the customers’ requirement of Improving the quality and filling at the price, the product life cycles must be shortened more and more. Most automotive factories introduce into some new virtual manufacture systems and […]

When the Apple iPad was announced back in January, it seemed like a natural fit as a drawing tablet. While we knew that it may not have the fidelity of a Cintiq, we also knew that it wasn’t meant to be used the same way. Now that the tablet is out and the flood of […]

The integration of advanced virtual engineering methods into 3D-CAD based development processes leads to increased requirements, concerning the software packages as well as regarding the applied procedures and strategies. Modern IT- based engineering tools offer much more than the conventional development methodologies in component creation and digital mock-up processes. The trend definitely goes into the […]

Virtual reality offers stylists the possibility to immediately sketch and model in 3D, combining the sketching and modelling stages of the design process. In this paper we describe MOVE ON, a new two-handed gesture-based Computer Aided Conceptual Design application for use in a virtual environment. The use of two-handed form-descriptive gestures to sketch and deform […]

SketchBook Mobile shares the same core technology as SketchBook Pro, resulting in an app that truly delivers professional-grade sketch capabilities and quality to a mobile device. In this exclusive interview, Andrew Meehan, digital artist and designer, shares his experience with SketchBook Mobile.

What is Digital Prototyping? Digital Prototyping gives conceptual design, engineering, and manufacturing departments the ability to virtually explore a complete product before it becomes real. With Digital Prototyping, manufacturers can design, visualize, and simulate products from the conceptual design phase through the manufacturing process, boosting the level of communication with different stakeholders while getting more […]

In the early stages of automotive design, designers produce a rich set of concept sketches to develop and communicate their ideas. These sketches convey useful information regarding the desired shape and style. However, creating a 3D digital model consistent with the sketch is a laborious process with existing CAD tools. This shortcoming limits most conceptual […]

We present an interactive pen-based computer program for designing 3D objects through direct sketching. The proposed techniques are tailored toward the creation of free-form curves and surfaces, and are therefore particularly useful for styling design purposes. In our approach, the design process consists of two main steps. In the first step, the user designs a […]

We present ILoveSketch, a 3D curve sketching system that captures some of the affordances of pen and paper for professional designers, allowing them to iterate directly on concept 3D curve models. The system coherently integrates existing techniques of sketch-based interaction with a number of novel and enhanced features. Novel contributions of the system include automatic […]

This paper describes StyleCam, an approach for authoring 3D viewing experiences that incorporate stylistic elements that are not available in typical 3D viewers. A key aspect of StyleCam is that it allows the author to significantly tailor what the user sees and when they see it. The resulting viewing experience can approach the visual richness […]
