K3-TENT
Tensile fabric design software. Shade sail design.
K3-Tent Software
K3-Tent is a software suite intended for designing tent structures. The software speeds up design documentation and improves the preparation of manufacturing orders for any tent structure. K3-Tent provides designers with clear, effective tools for working with complex surfaces. K3-Tent significantly reduces the time for form-finding, visualization, cutting line marking, and piece unfolding. The K3-Tent suite is a further development of the FABRIC CAD System.
Examples of shade sail models
K3-Tent software allows you to create various shapes limited only by your imagination.
What К3-Tent software provides
K3-Tent is a complete software solution for engineers and architects working with tensile membrane structures. Whether you need to design a small shade sail or a complex stadium roof, K3-Tent provides specialized tools for every stage of the project: from initial form-finding to precise cutting pattern generation.
Form-finding
Finding the equilibrium shape under given boundary conditions.The algorithms used in the K3-Tent software allow for finding the surface shape without bubbles or wrinkles (i.e., ensuring a smooth, physically accurate tensioned surface).
Cutting line
Tracing future cutting lines. Three methods for constructing the line: the shortest line, intersection with a vertical plane, or intersection with an arbitrary plane.
Creating patterns
Creating a pattern taking into account the seam (weld) width. Generating a coordinate grid for transferring the pattern to the fabric.
Stitching patterns
Creating a stitching scheme
Overall stress heat map
K3-Tent software automatically calculates and visualizes a heat map of the overall stress distribution on the fabric membrane, and also calculates the reaction forces at the membrane attachment points.
Surface curvature analysis
You can analyze the surface shape using contour lines (isolines) or a heat map of the normal deviation from the vertical axis.

Prices
We offer flexible licensing to suit your project needs:
- 1-month license – 150 USDT. A constant internet connection is required.
- 1-year license – 1440 USDT. Supplied with a software protection key. A constant internet connection is not required.
- Perpetual, unlimited license – 3600 USDT. Supplied with a software protection key. A constant internet connection is not required.
Why we use cryptocurrency payments
Due to international banking restrictions affecting Russian companies, we are currently unable to receive wire transfers (SWIFT) from abroad.
However, we have chosen cryptocurrency (USDT / USDC) as an alternative — not because it’s risky, but because it’s faster, cheaper, and more transparent than traditional bank transfers.
No hidden fees – you pay exactly the network fee (usually $1–$5), not 3–5% bank commission.
Instant settlement – no 3–5 business days waiting for funds to clear.
Full traceability – every transaction is recorded on the blockchain, which means you have a verifiable proof of payment.
We issue a formal invoice (PDF) with our company details. After payment, you receive a permanent license key and full technical support, just like with any traditional purchase.
If you are not familiar with crypto, we provide a step-by-step guide and personal assistance – just contact us.

FAQ
Frequently Asked Questions about K3-Tent Software.
1. What types of shade sails can I model in the software?
Examples of surfaces are shown in the screenshots above.
The K3-Tent software simulates the shape of a "soap film" surface for a specific frame. The K3-Tent software simulates the shape of a soap film surface for a specific frame when it is lifted from a soap solution. The frame can consist of rigid or stretchable (rubber) ribs.
You change the shape of the frame, and K3-Tent automatically creates the optimal surface without bubbles or wrinkles.
2. Does K3-Tent calculate wind, snow, and rain loads?
K3-Tent does not account for the effects of wind, rain, or snow. K3-Tent calculates the stresses in the fabric resulting from pre-tension and the weight of the fabric itself. It also calculates the reaction forces at the tent attachment points.
3. Can you manufacture a tensile structure according to our request?
Our company does not create commercial projects. We develop the K3-Tent software.
4. Can you provide ready-made tensile structure projects?
All the projects we have are created by our users. We cannot provide working projects without the consent of our users. Each project is created individually for a specific location.
5. Can I create a steel structure in K3-Tent?
A steel structure can be created in K3-Tent. K3-Tent includes a full-featured 3D editor. However, most users prefer to use their preferred software for steel structure design. The model is then imported into K3-Tent. Based on the imported structure, K3-Tent finds the optimal surface shape. K3-Tent supports 70 import formats.
6. How do I transfer the patterns created in K3-Tent to real fabric?
All patterns can be exported in DXF format. The work then continues with these DXF files.
There are several ways to transfer the pattern to the fabric:
- Loading the DXF contours of the patterns into a CNC plotter with a cutting knife and a marking module.
- Printing the pattern contour on a roll printer and then tracing the contour onto the PVC fabric.
- K3-Tent automatically creates a coordinate grid under the pattern contour. The grid spacing is specified when creating the pattern. This coordinate grid can be used to transfer the pattern onto the PVC fabric.
7. How can I learn to work with the K3-Tent software?
The software comes with a "User Guide" in PDF format. There are also links to YouTube and Rutube channels with tutorial videos. We are also ready to record custom training videos upon your request.
8. How is user technical support provided?
Technical support is provided via email and the Telegram messenger.
For 12 months after purchasing a perpetual license, technical support is free of charge. Technical support is also provided free of charge with the purchase of a monthly license..
9. What are the system requirements for running K3-Tent?
This is one of the most frequent questions asked when purchasing K3-Tent. To avoid unpleasant situations related to unsuitable hardware, here is the full list of requirements:
- Pay special attention to the graphics card. We recommend using NVIDIA video adapters. Each new version of K3-Tent increasingly utilizes hardware capabilities.
- The amount of RAM determines the performance of the operating system in general and the K3-Tent software in particular.
- The screen size and resolution determine the quality and quantity of simultaneously visible lines.
- Recommended graphics adapter specifications for K3-Tent: A discrete graphics card (NVIDIA GeForce, ATI RADEON) supporting OpenGL version 4.2 or higher, with at least 1 GB of dedicated memory.
- Please note: Integrated Intel HD graphics cards do not meet the recommended system requirements and do not provide full system functionality.
- If K3-Tent is installed on a laptop with two graphics cards, ensure the program runs using the discrete graphics card.
Recommended system requirements:
- Processor 3-GHz ;
- Computer memory 16 GB;
- Graphics card NVIDIA with 1 Gb memory or more;
- Monitor diagonal 20" and more. Screen resolution 1600х1200;
- Two-button mouse with a scrolling wheel;
- Free 3 Gb of hard disk space;
- Supported operating systems Windows 7, 8, 10, 11
