[Discover the key benefits of how SecturaFAB accurately identifies length with centerline technology.](https://help.secturafab.com/uploading-linear-cad-files?hsLang=en#_Key_Benefits)   ### Key Benefits   ### Enhanced Length Detection for Rotated Parts:   - **New Centerline Technology**: We've implemented advanced centerline technology that accurately calculates the length of linear parts, even when they are drawn at a rotated orientation. This enhancement ensures that the true length of the geometry is measured, providing precise measurements for all linear parts, regardless of their orientation. ![](https://help.secturafab.com/hubfs/Knowledge%20Base%20Import/29192889948827.png)   ### Accurate Measurement for Bent Tubes:   - **Extended Accuracy**: The new centerline technology also applies to bent tubes, a feature that was previously unavailable. This improvement guarantees that both straight and bent tubes are measured correctly, enhancing the overall accuracy of your quotes and estimates. ![](https://help.secturafab.com/hubfs/Knowledge%20Base%20Import/29192913385755.png)     Related to - [STEP](https://help.secturafab.com/hc/en-us/search?content_tags=01H39WN5ADJGKCGRYQD7S1S03D&utf8=%E2%9C%93&hsLang=en) - [CAD](https://help.secturafab.com/hc/en-us/search?content_tags=01H39YW7H05JKMJPTDCT3B51TR&utf8=%E2%9C%93&hsLang=en) - [linear](https://help.secturafab.com/hc/en-us/search?content_tags=01HAMAZKZXRBV0T0G21J7DJ235&utf8=%E2%9C%93&hsLang=en) - [Getting started](https://help.secturafab.com/getting-started?hsLang=en#main-content) - [Preferences](https://help.secturafab.com/getting-started?hsLang=en#preferences) - [Quote Detail](https://help.secturafab.com/getting-started?hsLang=en#quote-detail) - [Quick Start](https://help.secturafab.com/getting-started?hsLang=en#quick-start) - [Operations](https://help.secturafab.com/getting-started?hsLang=en#operations) - [Organization Settings](https://help.secturafab.com/getting-started?hsLang=en#organization-settings) - [Cost](https://help.secturafab.com/getting-started?hsLang=en#cost) - [Customization](https://help.secturafab.com/getting-started?hsLang=en#customization) - [Integration](https://help.secturafab.com/getting-started?hsLang=en#integration) - [Personal Settings](https://help.secturafab.com/getting-started?hsLang=en#personal-settings) - [Inventory](https://help.secturafab.com/getting-started?hsLang=en#inventory) - [Security](https://help.secturafab.com/getting-started?hsLang=en#security) - [General](https://help.secturafab.com/general?hsLang=en#main-content) - [FAQ](https://help.secturafab.com/general?hsLang=en#faq) - [Announcements](https://help.secturafab.com/general?hsLang=en#announcements) - [Product Updates](https://help.secturafab.com/general?hsLang=en#product-updates) - [Tools and Configurations](https://help.secturafab.com/tools-and-configurations?hsLang=en#main-content) - [Materials and Products](https://help.secturafab.com/tools-and-configurations?hsLang=en#materials-and-products) - [SecturaSYNC](https://help.secturafab.com/tools-and-configurations?hsLang=en#secturasync) - [Operations](https://help.secturafab.com/tools-and-configurations?hsLang=en#operations) - [QuickTIPS](https://help.secturafab.com/tools-and-configurations?hsLang=en#quicktips) - [Importing Geometry](https://help.secturafab.com/tools-and-configurations?hsLang=en#importing-geometry) - [Frequently Asked Questions (FAQs)](https://help.secturafab.com/frequently-asked-questions-faqs?hsLang=en#main-content) - [Quoting](https://help.secturafab.com/frequently-asked-questions-faqs?hsLang=en#quoting) - [General](https://help.secturafab.com/frequently-asked-questions-faqs?hsLang=en#general) - [Setup](https://help.secturafab.com/frequently-asked-questions-faqs?hsLang=en#setup) - [What's New](https://help.secturafab.com/whats-new?hsLang=en) [![SecturaFAB by Stella Source\_400x100 1-1](https://help.secturafab.com/hs-fs/hubfs/SecturaFAB%20by%20Stella%20Source_400x100%201-1.png?width=200&height=50&name=SecturaFAB%20by%20Stella%20Source_400x100%201-1.png "SecturaFAB by Stella Source_400x100 1-1")](http://www.stellasource.com) Copyright © 2025, Stella Source
