Darmstadt Graphics Group video testimonial

The study on consumer behavior by IBM Institute for Business Value clearly shows that there is a high awareness of new digital shopping technologies. What’s more, a large share of respondents expressed their desire to try them: visual search (40%), smart dressing room (41%), and virtual reality (50%). So classical photos of the product, even from several angles, are not enough for winning the market anymore.

The brands, for their part, respond to these market demands. Such giants as Google, Pinterest, Bing, and eBay integrate visual search solutions. Timberland, Topshop, and Lacoste are among the…

Introduction

ACIS is one of the two most popular geometric kernels, powering a lot of CAD, CAM, CAE, and AEC software. It’s more than 30 years old, having been originally created in the ’80s and is currently developed by Spatial (part of Dassault Systemes). Like any other 3D geometry kernel it provides a basis for the engineering and design applications in the form of data structures to represent 3D models and various geometric algorithms to operate on them. To enable saving and loading of 3D models in between the modeling sessions it exposes…


Our only regret in this CAD Exchanger version is that being released during the low season, it competes for your attention with such a stronghold as summer vacations. But when it comes to two new native formats and an all-formats reader and writer, none of the sunny routines can beat us.

Here are the highlights of CAD Exchanger GUI 3.10:

  • 3D XML (CATIA V6) import
  • Solid Edge import
  • Mesh colors import in SOLIDWORKS
  • Broader versions coverage for CATIA, JT, Parasolid, SOLIDWORKS
  • Y-axis upward orientation in Collada, FBX, GLTF, OBJ
  • Read and write PMI options for STEP and JT

The industrial infrastructure prefabrication sector is growing and saving costs by reducing on-site work and thus the need for additional production, assembly, and quality control tools and workforce. However, this practice demands greater accuracy to ensure compliance between assemblies from different manufacturers. A research perspective issued by the Navigant Construction Forum™ (USA) shows that the median cost of field rework is 5.04% of a full project cost. Whether its cause lies in design, measurement, or communication constraints, the result is the same — someone has to pay for it a great deal of money.

The grand purpose of CAD Exchanger is compatibility between CAD, CAM, CAE, PDM, and other steps of a product life cycle. In the mid-1980’s STEP format, also known as ISO 10303, was created with the same objective and became a common standard for CAD data exchange. Sure enough, STEP was one of the first formats supported by CAD Exchanger and the one with high priority for further improvements.

In 2016 STEP importer was boosted with parallel computations that dramatically reduced files processing time. Then, CAD Exchanger took consistent steps to provide full PMI support for this format in 2019–2020. The…

Part 1. IGES

Introduction

STEP stands for Standard for Exchange of Product model data. It originated from a Product Data Exchange Specification (PDES) which was developed in the mid-1980s by the same group that created IGES. Initial aim of STEP was to supersede a few older exchange formats, such as IGES and VDA-FS and to provide a unified implementation-independent data model for products from all kinds of industries. This grand aim necessitated the specification to be split into multiple pieces, defining different aspects of product representation (structure representation, geometry representation, persistence mechanism, etc.). …


This post is a translation of an article published by Denis Kolisnichenko in Xakep.ru (stands for “Hacker”) on August 14, 2018. The original version (in Russian) is available online at https://xakep.ru/2018/08/14/3d-cad-exchanger/.

We all believe that domestic programmers are the best in the world. Not so often, but still it happened that a Russian company challenged the existing conservative order in the industry, and each of these success stories, in our opinion, deserves detailed consideration — both from the technical and organizational points of view. …

Metadata in CAD models: more than just a 3D model

Although 3D geometry and product structure considered in previous parts are the most important assets in the CAD model for many applications, they are not the only ones. Many apps make use of additional information such as names and colors, persistent IDs, layers, user-defined properties and others. All these types of information enrich the 3D model and provide context for it: design intent, manufacturing or…
