ZWSOFT Releases CADbro 2021

GUANGZHOU, China, Sep 24, 2020 – ZWSOFT announced the release of CADbro 2021, an easy-to-use 3D CAD viewer for whoever needs to collaborate on engineering data, especially salespeople, technicians, quality controllers, designers, etc.

Import More Information in Less Time

Importing a 3D CAD file is the first step to use a viewer. Now that the translator of CADbro has been upgraded, you can not only import more versions of files, such as CATIA V5-6R2020, Creo 6.0, Inventor V2020, and NX 1899, but also access their part attributes, for example, material. Hence, providing a quotation takes less time.

Besides, the Quick Import command can help load the display data in short order and the geometric data for measuring or basic editing as well.

Quicker Modification of and Easier Collaboration on 3D Models

With the 3D model imported, you can begin modifying it in the desktop app. If you are not yet familiar with CADbro, the newly added Command Search function is here to help you find the command needed.

Plus, the Coordinate System is available in CADbro 2021. As a result, you can create Datum CYSY and axes effortlessly. They can facilitate the measurement of objects. As a type of reference geometries, Datum axes, in particular, are commonly used as the center of rotation and are especially useful when the axis of a particular model is not in line with any default coordinate indicator.

For the assembly, you can use the new Clearance Check function to check the minimum distance between components. It can help you ensure a safe and reasonable assembly design.

With the model ready, you can predefine the explode steps in the desktop app and upload them along with the model to the cloud. After that, your project members or clients can examine the exploded view according to the pre-defined steps on the web.

Share Smaller Files via QR Code

As QR (Quick Response) code gains popularity, your customers might prefer scanning one to view your product information on their mobile devices. Now, it’s feasible to generate a QR code for your model file in CADbro 2021 and share it via the code.

Kubotek3D Releases Kubotek K-Compare, K-Display v3.0

MARLBOROUGH, MA, Sep 24, 2020 – Kubotek3D, a leading supply chain software provider, announced the 3.0 release of the Kubotek K-Compare and K-Display software products. This major release provides updates to STEP and CAD file readers, user interface improvements, and several new functions for each product. The new releases are available for customers to download immediately.

Major STEP File Enhancements

Kubotek proprietary readers for STEP (ISO 10303) files have been expanded in two important ways. The first major STEP enhancement covers complete reading of AP 242 Product Manufacturing Information (PMI) to support customers practicing Model-based Definition (MBD). STEP AP 242 defines critical manufacturing annotations including Geometric Dimensioning and Tolerancing (GD&T) and their unambiguous relationship to the faces of the 3D model. MBD can provide process efficiency by eliminating the need to translate the design into detail drawings and better support automation of downstream activities such as NC machining and inspection.

The second STEP enhancement is added support for opening compressed ASCII STEP files which use the extension “.stpZ”. Compressing STEP files into the stpZ format improves transfer of large data sets and has been gaining in popularity since originally released in 2013, especially in the aerospace and automotive industries. This new feature is included in all K-Display and K-Compare product levels. For engineers receiving compressed stpZ files, K-Display Convert can uncompress stpZ files to standard stp files which can be read by most CAD programs.

Updated CAD Readers

Reading of 3D CAD files across all 3.0 Kubotek software programs has been updated to support new versions of four major CAD file formats:

  • Siemens NX 1919, 1915, and 1911 (1899 Series)
  • Dassault CATIA V6/3DExperience R2020x
  • PTC Creo 7.0
  • Autodesk Inventor 2021

K-Compare Major Enhancements

Improvements in K-Compare have focused on further increasing user productivity. Comparison of two sets of hierarchical assembly CAD files has been enhanced to support quick side-by-side 3D graphical viewing of the entire assembly or just a set of paired parts. In the graphical view users can immediately browse the difference results tree details and see face highlighting on the impacted parts.

The new automatic Locator View option in the report creation mode of K-Compare Revision saves users the time of creating and annotating extra explanatory views. The Locator View provides the reader a quick frame of reference for views that are zoomed up on a part detail. The Locator View appears in the corner of the view, always stays at full scale (Zoom Fit), and maintains the same 3D orientation as the view. A dynamically linked rectangle over the locator view indicates where on the part the main view window is displaying.

K-Display Major Enhancements

The 3.0 release introduces basic feature recognition capabilities to help users quickly evaluate part details based on geometry from any supported CAD format. During file read K-Display scans the face geometry and topology to builds lists of all machined holes, constant radius fillets, and general chamfers and includes a folder for each in the part tree. Data under each feature folder list relevant sizes such as diameter and depth for a blind hole. Hovering the cursor over the faces of these geometric features also provides a ToolTip which displays size information. This information aids in process planning and selection of tools for NC programming.

A new user option has been added to K-Display programs to support reading all non-primary variants of the 3D data in the CAD file. For a SolidWorks file, variants might be additional part configurations, or for a CATIA 5 file it may be scenes saved in the file. Having an option to decide to read variants or not is important because for many user applications this data is unnecessary, slows down file read, and may even lead to confusion. In other cases, having access to this variant data can be crucial to fully understanding the design.

Free trials of Kubotek software are available. Kubotek3D is also seeking referral partners and qualified resellers for these products.

UTA, Ansys Announce Design, Analysis Workflow

PITTSBURGH, PA, Sep 23, 2020 – The University of Texas at Arlington (UTA) and Ansys are developing an advanced design and analysis workflow for validating system models in the US government’s current and next-generation hypersonic vehicles. The workflow will fast-track certification of simulation software codes, help decrease hypersonic technology development spending and increase engineering productivity.

The US Department of Defense and NASA have prioritized the development of high-speed hypersonic aircraft, spacecraft and missiles. However, funding may not be sustainable as a single prototype flight test costs taxpayers as much as $100 million dollars. Additionally, there is a shortage of engineers with hypersonic vehicle design experience. While these factors have slowed the advancement of hypersonic flight, Ansys’ simulation solutions help spur the development of key hypersonic technologies ranging from thermal protection systems for spacecraft reentry to scramjet combustion technology for hypersonic travel.

Ansys’ high-fidelity physics-based solvers spur hypersonics experimental research — from simulating the design and analysis of air and fuel mixing inside a scramjet to measuring the impact of thermal stresses on vehicle sensors that operate in harsh environments. By simulating these systems, engineering teams can save hundreds of millions of dollars in physical prototype testing and further research and development using fewer employees. After running Ansys’ hypersonic systems models, UTA engineers can verify the software code’s accuracy by conducting physical high-speed flight tests in UTA’s state-of-the-art arc jet hypersonic wind tunnel — the only structure of its kind created by a US university.

“Testing and validating physics-based component models within a wind tunnel that operates at hypersonic speeds and temperatures delivers a major technological advantage for our mutual customers, driving faster development of cost-effective solutions,” said Luca Maddalena, professor of Aerospace Engineering and director of the UTA’s Aerodynamics Research Center. “The university’s arc jet will help validate Ansys’ software codes for hypersonic applications and power leading-edge research in aerothermodynamics, scramjet propulsion, ablation and much more.”

“Our mutual customers in the air and space domains demand substantial reductions in time to market, which creates tremendous challenges for engineering highly complex hypersonic vehicles,” said Prith Banerjee, chief technology officer at Ansys. “By working closely with one of the top universities in hypersonics research, our combined capabilities will shift the paradigm away from expensive and lengthy physical prototype testing to significantly advance the development of current and future hypersonic vehicles.”
