Well, that didn’t take long. It was only a few weeks ago that we learned that CoCreate was in play and PTC was the suitor. This acquisition reinforces the consolidation of the MCAD industry that continues to march on. Is it necessarily a good or bad thing? Like most mergers and acquisitions, it depends on how you look at it. Sometimes it’s not necessarily strictly one or the other, and often proves to be a bit of both, and I’m sure that will be the situation here. With the acquisition, PTC actually acquired the CoCreate OneSpace suite consisting of the core 3D modeling application, a PDM application, and a Web-based application for collaborative project
It’s ironic that PTC, with its strong legacy in parametrics, would acquire a company whose design philosophy in some respects goes counter to PTC’s, although it does illustrate a major trend occurring in the MCAD industry that is increasingly developing non-history-based methodologies and direct geometry editing, something that CoCreate calls Dynamic Modeling.
CoCreate’s non-history-based modeling approach, is unique, but is by no means is the company alone in offering it . Model history, of course has its place, but a history-based approach to 3D modeling is not always the best way to go, and CoCreate’s customer base proves this. However, as previously mentioned, the non-history-based approach is not exclusive to CoCreate OneSpace Modeling, because Kubotek’s KeyCreator, UGS’ NX5, and IronCAD also employ it, although with slightly different methods, but the results are largely the same. A history-based approach is what most parametric modelers (such as Pro/ENGINEER) employ, but it’s not always the best method or
approach, especially for changes made to a model late in the design process. This is because history-based systems use a history tree to track and replay 2D profiles and modeling steps for generating and modifying 3D geometry. The main drawback is that each step in the history is dependent upon the profile and modeling step that came before it. The further along you get in the design process, the more complicated the design and its associated history become.
On the other hand, a non-history based approach is well-suited for manufacturers that change designs late in the design process, so they are not bound by the constraints and complications that a history tree can impose. Also, a non-history-based system can make data import easier because you don’t have to worry about the overhead of dealing with a history tree from a different system. Neutral file formats, such as IGES and STEP, are for all intents and purposes, native data to CoCreate OneSpace Modeling and other non-history based MCAD applications. This eliminates the burden of legacy data originating from another system.
CoCreate is the latest in a long series of acquisitions that PTC has made over the years that have included Computervision, Mechanica,Arbortext, and Mathcad. How will CoCreate’s product line fit into the mix? That’s hard to say because there is some overlap of the products, especially on the PDM side, but things should start sorting themselves out pretty quickly.
Will the relative incompatibility of the product lines come back to haunt PTC as it has with some of its past acquisitions? It will be interesting to see which, if either, one ultimately wins – CoCreate’s dynamic, non-history-based modeling; PTC’s explicit (the term that PTC is using for dynamic modeling since the acquisition announcement), parametric technique; or an optional choice between the two. Other companies are offering the choice, so why not PTC?. In my book, this acquisition was one the biggest events to occur in the MCAD community for 2007. And, I predict that sooner rather than later, there will be as many as two to three more smaller MCAD vendors
swallowed up by bigger fish, that themselves may or may not already be a player in the MCAD arena. As always, next year promises to be another year filled with unexpected twists and turns for the MCAD community.
The Week’s Top 5
At MCADCafé we track many things, including the stories that have attracted the most interest from our subscribers. Below are the five news items that were the most viewed during last week.
Dassault Systemes launched its new desktop content authoring system, 3DVIA Composer V6R1. New features and packaging for 3DVIA Composer include:
Enhanced Animations and Views. 3DVIA Composer permits users to copy and paste among objects and to drag views in animations. These enhancements were implemented to provide advanced 3D capabilities to non-technical desktop users.
Support of ellipses in 2D vector graphics. 3DVIA Composer can automatically generate technical illustrations from 3D data as part of an integrated desktop system. With these enhancements, technical illustrators can produce more accurate illustrations
Innovative rendering capabilities. 3DVIA Composer offers the ability to render individual objects. Also included are new lighting objects. An innovative new capability called Layered Rendering allows desktop users to build up rendering of parts and assemblies to achieve the most appropriate visual representation of a procedure or process.
Improved performance for large assemblies. 3DVIA Composer's performance, a benefit of its XML-based architecture, is enhanced with new load-on-demand capabilities and support for interactively browsing large assemblies.
CD-adapco today announced the release of STAR-CD V4.04 that introduces new capabilities, including:
A new version of pro-STAR that utilizes an advanced GUI with improvements in usability and speed.
Improved capabilities for melting and solidification, which is now integrated with the stress analysis capability, allowing the prediction of residual stresses in the solidified phase.
The introduction of new physical modeling capabilities, including liquid film stripping.
A mesh morphing capability that simplifies moving mesh simulations, fluid-structure-interaction calculations and optimization studies.
Greater reliability and improved solver speed, resulting in significant decreases in run time.
Integration of the latest STAR-CCM+ meshing technology, including the surface wrapper and polyhedral mesher.
3D3 Solutions announced the addition of Leios Mesh to its 3D scan processing product line. Previously only available as part of a packaged offering, Leios Mesh is now available as a stand lone product. Leios Mesh processes 3D scan data developed by Italian company, EGS. The software takes raw 3D data from 3D scanners or touch probes and transforms the data into a 3D model for use in downstream applications. Leios Mesh is an application for 3D reverse engineering and surface reconstruction. Key features of Leios Mesh include:
Point cloud processing and cleanup
Mesh alignment and stitching
Mesh repair and editing
Inspection and measurement
Solids and surface creation
Geometric Ltd. announced version 2.1 of GeomCaliper for Pro/ENGINEER, focusing on usability and performance enhancement related features. The major enhancements in this release of GeomCaliper for Pro/ENGINEER include:
Enhanced Reporting: Reporting mechanism for thickness analysis results can capture multiple critical regions along with their static image snapshots in one report now.
Customizable color band: Color band displayed with thickness analysis results can now be customized to specify user defined intervals including range and color for each interval.
Contact Distance: In sphere method for thickness analysis, the user can opt to view contact distance between touch points rather than diameter of sphere.
Enhancements in Critical Region Analysis tool: Enhancements in critical region analysis tool include the ability to quickly locate critical regions outside of allowed thickness range, setting default options to view region or clipped section at pre-defined angles, turning animation on-off during critical region analysis, and defining or modifying parameters like status, color, review comments on multiple regions at same time.
Improvements in Performance -- computation time reduced by up to 30%, and significant improvement in visualization performance resulting in 150% improvement in FPS rate. Bigger and complex models are now processed much faster.
