Kernels act as the bridge between keyboard, mouse and display, and the computer\u2019s processor. The kernel turns complex commands such as \u201cchange the dimension of the flange\u201d into machine-intelligible instructions and collects the result for display, through the application, back to the user.<\/p>\n\n\n\n<p>Most computer-aided design (CAD) systems were designed with a specific kernel in mind but can, with time and care, be modified to rely on another kernel for application-to-machine instructions. Each kernel has its strengths, weaknesses, and peculiarities, making a change from one kernel to another difficult on users. In a kernel swap, users must convert part libraries and test connections to third-party programs and other interfaces. Part version control is crucial to highlight that a part is converted but otherwise the same as the legacy part.<\/p>\n\n\n\n<p>In the end, each user team must decide which is less disruptive: Converting parts to take advantage of the new kernel\u2019s benefits or switching to a different CAD package and keeping the same kernel. Each alternative involves risk but also the potential for benefit. Moving to a new tool may change your design department\u2019s trajectory, offering new capabilities and opportunities for growth.<\/p>\n\n\n\n<div class=\"wp-block-cover alignwide has-background-dim-60 has-background-dim is-repeated has-background-gradient is-position-center-center\" style=\"background-image:url(https:\/\/blogs.sw.siemens.com\/wp-content\/uploads\/sites\/8\/2021\/06\/017.053_GBL_ARPT_Schnitger-Kernel-Change.jpg);min-height:50px;aspect-ratio:unset;\"><span aria-hidden=\"true\" class=\"wp-block-cover__gradient-background has-midnight-gradient-background\"><\/span><div class=\"wp-block-cover__inner-container is-layout-flow wp-block-cover-is-layout-flow\">\n<div class=\"wp-block-columns alignwide is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:12%\">\n<div style=\"height:100px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>New Math: The Hidden Cost of Switching CAD Kernels<\/strong><\/h2>\n\n\n\n<p>Why should you care about what CAD kernel your vendor uses \u2013 and why do you need to know their long-term kernel strategy?

Old CAD on old hardware was a non-starter, leaving migrating everything to a new CAD system. But what to convert to?<\/p>\n\n\n\n<p>They already used SolidWorks in part of their business and considered moving the legacy parts to that platform. One big problem: Many of the newest features in SolidWorks rely on the Dassault Syst\u00e8mes 3DEXPERIENCE platform. The traditional desktop version of SolidWorks is built on the Parasolid kernel, a&nbsp;geometric modeling kernel owned and developed by&nbsp;Siemens Digital Industries Software, which can be&nbsp;licensed&nbsp;by other companies for use in their&nbsp;3D computer graphics&nbsp;software products. On the other hand, the 3DEXPERIENCE platform uses the CGM kernel. The company\u2019s reliance on two kernels led many users to worry that building parts in SolidWorks will eventually mean a wholesale conversion from Parasolid to CGM. <\/p>\n\n\n\n<p>This raised a big question: if they were to migrate everything today, would they have to do it again in a few years?<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"646\" height=\"454\" src=\"https:\/\/blogs.sw.siemens.com\/wp-content\/uploads\/sites\/8\/2021\/07\/Solid-Edge-OEM-caption2.jpg\" alt=\"\" class=\"wp-image-12570\" srcset=\"https:\/\/blogs.sw.siemens.com\/wp-content\/uploads\/sites\/8\/2021\/07\/Solid-Edge-OEM-caption2.jpg 646w, https:\/\/blogs.sw.siemens.com\/wp-content\/uploads\/sites\/8\/2021\/07\/Solid-Edge-OEM-caption2-600x422.jpg 600w\" sizes=\"auto, (max-width: 646px) 100vw, 646px\" \/><\/figure>\n\n\n\n<div style=\"height:25px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>You can learn more about this company\u2019s decision-making process in <a href=\"https:\/\/solidedge.siemens.com\/en\/resource\/report\/switching-cad-kernels\/\" target=\"_blank\" rel=\"noopener\"><em>The Hidden Cost of Kernel Change<\/em><\/a> \u2013 a report published by Schnitger Corporation. In the report, you\u2019ll learn that converting from one kernel to another can be extremely challenging. If there\u2019s an opportunity to avoid a kernel change, you should definitely investigate this possibility. <\/p>\n\n\n\n<p>The company featured in the Schnitger Corporation report decided that it couldn\u2019t afford the risk, disruption, and uncertainty an unclear future might cause. That\u2019s why they chose <a href=\"https:\/\/solidedge.siemens.com\" target=\"_blank\" rel=\"noopener\">Solid Edge<\/a>, which also uses the Parasolid kernel.
