Why we like it

TechSec earns its place in the Superhive library for bringing SVG technical sectioning into Blender, combining dimensions, hatching and multi-scale page layout for architecture, engineering and CAD work.

What is Techsec?

TechSec (Technical Section) generates static and interactive SVG technical sections based on Blender mesh geometry. Sections can be output as SVG and PNG at a specified scale, with line weights, angular and linear dimensions, text annotations and hatching patterns that can be set at individual object or collection level. Common ISO page sizes are also supported.

Multiple section cuts at various scales can be combined into one final page. PNG sections can be applied and visualised interactively on Blender geometry, and complex geometry can be used to create interactive sections such as staggered sections. Camera control automates the application of rendered image backgrounds to the produced SVG sections.

The emphasis is currently on architecture, with general engineering and CAD applications as well. TechSec has been tested on Windows 10/11 (x86-64 only), macOS (Intel and m-series) and Linux (x86-64 only); on Linux a local installation of Cairo is required. It works with Blender 4.0 to 4.5 and is distributed under a GPL license.

Who is Techsec best for?

Frequently asked questions

Does TechSec work with Blender 4.5?

TechSec lists compatibility with Blender versions 4.0 through 4.5, so recent releases in that range are covered. The addon works directly with Blender mesh geometry to create technical sections and outputs them as SVG and PNG files. It is distributed under a GPL license. For the most current version support and any updates beyond this range, the developer's page is the place to check before installing.

What operating systems does TechSec support?

TechSec has been tested on Windows 10 and 11 (x86-64 only), macOS on both Intel and m-series machines, and Linux (x86-64 only). On Linux, a local installation of Cairo is required for the addon to function. Across these platforms the tool creates SVG and PNG technical sections from Blender geometry. If you run a different architecture or setup, checking the developer's page before installing is worthwhile.

Do I need Cairo to run TechSec on Linux?

TechSec requires a local installation of Cairo when running on Linux. On Windows 10/11 and macOS (Intel and m-series) this extra step is not listed. The addon generates SVG and PNG technical sections from Blender mesh geometry, including line weights, dimensions, text annotations and hatching patterns. Linux users should confirm Cairo is installed before setting up the addon so that section output works as expected.

Is TechSec free to use?

TechSec is listed as free in this catalog and is distributed under a GPL license. Licensing terms can change over time, so for current details it's best to check the developer's page directly. The addon creates static and interactive SVG technical sections from Blender geometry, with support for ISO page sizes, line weights, dimensions, text annotations and hatching patterns for architecture, engineering and CAD work.

Can TechSec combine multiple section cuts on one page?

TechSec allows multiple section cuts at various scales to be combined into a single final page. It can also apply and visualise PNG sections interactively on Blender geometry, and use complex geometry to build interactive sections such as staggered sections. Camera control automates the application of rendered image backgrounds to the produced SVG sections. Line weights, dimensions, text annotations and hatching patterns can be set at individual object or collection level.
