FredoScale is a cornerstone extension for SketchUp, offering advanced geometric transformations like tapering, stretching, and radial bending that far exceed the capabilities of native tools. Since March 1, 2022, this essential plugin has transitioned from a free tool to a paid model under the Sketchucation SCFLicense system. Current FredoScale License Pricing

As of 2024–2026, users have two primary ways to acquire a perpetual license through the Sketchucation PluginStore :

Individual License: Approximately $12 to $15 USD for a perpetual license that includes 3 seats (activations on up to three different computers).

Fredo6 Bundle: Approximately $40 to $50 USD. This is often recommended by experts as it includes eight of Fredo6's most popular plugins, such as Curviloft, JointPushPull, and RoundCorner. License Types and Trial Period

30-Day Free Trial: New users can access the full features of FredoScale for 30 days starting from the first usage before a license is required.

Perpetual License: This is a one-time purchase, not a subscription. Once bought, the license for that version does not expire.

Corporate/Volume Licensing: For firms requiring more seats, a corporate license can be managed through a generic Sketchucation account and validated against centralized license files. Critical Requirements for Activation

To successfully install and activate a FredoScale license, you must have the following dependencies installed: LibFredo6 - SketchUcation

The FredoScale license marks a significant shift in the SketchUp extension ecosystem, transitioning from a decade of free availability to a paid "Perpetual License" model managed via SketchUcation Overview of the Licensing Model

As of March 1, 2022, FredoScale moved to a paid model to support ongoing development. The current license structure includes: Perpetual License : A one-time purchase of $12 to $15 per individual plugin. Fredo6 Bundle Fredoscale is a paid extension for SketchUp that

: A more cost-effective option for power users, offering eight popular plugins (including FredoScale, Curviloft, and JointPushPull) for approximately $40 to $50. 3-Seat Allowance

: Each individual license typically covers up to three different computers (seats) for a single user. Free Trial

: A 30-day full-featured trial period is available for new users to test the tools before purchasing. Technical Requirements

To activate and maintain the FredoScale license, the following technical components must be installed and up-to-date within SketchUp:

: The foundational library for all Fredo6 plugins (e.g., version 14.3b or higher). SketchUcation ExtensionStore

: The plugin manager (e.g., version 4.4.0 or higher) required to validate the SCFLicense License Management and Validation Users manage their purchases through the My Licenses page on SketchUcation. Validation

: After purchasing, users must open the extension's license dialog in SketchUp (e.g., Tools > Fredo6 Collection > FredoScale > License ) and validate the license file. Seat Release

: If moving to a new machine, users may need to release a seat from an old device to free it up for the new one.

: For payment or validation issues, users often seek help via the SketchUcation community forums Impact on the Community

While the shift from free to paid met some initial resistance, the consensus among professional users is that the nominal fee is a fair "return on investment" for tools that significantly enhance SketchUp's core functionality. These tools, which allow for advanced scaling, twisting, and bending without distorting geometry, remain industry standards for professional modeling workflows. Fredo Licensing - SketchUp Forum

3. Pros of the FredoScale Licensing

✅ One-time payment – No annual fee, unlike many modern SketchUp extensions moving to subscriptions.
✅ Works offline – Great for secure environments or poor internet.
✅ Bundle value – Pay once for ~8 major tools (RoundCorner alone is worth the price).
✅ No DRM spyware – No phone-home checks every launch.
✅ Generous trial – 30 days to fully evaluate, not feature-crippled.
✅ Perpetual – You keep the last version you paid for, even if you don’t renew (but there’s no renewal anyway).

5. Support and Updates

A valid license usually grants the user access to updates and bug fixes for the duration of the license term. Depending on the specific terms at the time of purchase (e.g., via the Extension Warehouse or a third-party retailer), a license may be a "perpetual" license (yours forever, perhaps with a limited update window) or a subscription model.

2. Types of Licenses

The FredoScale license is generally categorized based on the type of user:

Single User License: This is the most common license. It grants one specific individual the right to install and use the software. The license is often tied to a specific machine or a user account ID.
Multi-Seat / Network License: For design firms or studios, volume licenses are available. These allow a specified number of users within an organization to access the plugin simultaneously.

7. TERMINATION

This License is effective until terminated. Your rights under this License will terminate automatically without notice from the LICENSOR if you fail to comply with any of its terms. Upon termination, You must destroy all copies of the Software in Your possession.

3. Usage Rights and Restrictions

When a user purchases a FredoScale license, they are not buying the software itself (the code); they are buying the right to use it.

Commercial Use: A valid paid license explicitly permits the use of FredoScale for commercial projects. Designers, architects, and engineers may use the tool to generate work for paying clients.
Educational Use: Fredo6 and the SketchUp Extension Warehouse often provide discounts or specific licensing terms for students and educational institutions, provided the software is used strictly for learning purposes and not for commercial profit.
Reverse Engineering: The license strictly prohibits reverse engineering, decompiling, or modifying the plugin's source code.
Redistribution: Users are not permitted to redistribute the license keys or the premium version of the plugin to third parties.

4. The "LibFredo6" Dependency

It is important to note that FredoScale runs on a common API library created by Fredo6 called LibFredo6. While FredoScale has its own specific license status, the functionality relies on this shared library. The license agreement covers the interaction between these two components.
