End User License Agreement

This agreement covers your use of the SunTools add-ins for Autodesk Revit. Please read it before you install the software or start a trial.

01Who this agreement is between

This End User License Agreement ("Agreement") is between you and SunTools, a product operated by Charles H. Logan III. In this Agreement, "SunTools", "we" and "us" mean SunTools and its operator. "You" means the person who installs or uses the software. If you accept this Agreement for a company or firm, "you" also means that company, and you confirm that you have authority to bind it.

"Software" means the SunTools add-ins for Autodesk Revit, including updates, settings files, documentation, and any license keys we provide.

02Accepting this agreement

By installing, activating or using the Software, you agree to this Agreement. If you do not agree, do not install or use the Software.

03Your license

While your subscription or trial is active and you follow this Agreement, we give you a limited, non-exclusive, non-transferable license to install and use the Software with Autodesk Revit for your own work or your firm's internal work.

04Free trial

We may offer a free trial of 30 days with every tool unlocked. The trial is for evaluating the Software. When it ends, the Software stops working until you buy a seat. Each person or firm may use one trial, unless we agree otherwise.

05Subscription, payment and renewal

06What you may not do

You may not, and may not let anyone else:

07Your models and your data

08Your responsibility for results

The Software changes your Revit model when you run it. For example, it places fixtures, draws wires, moves tags and fills in schedule values.

Test every tool in a blank or test project before you use it on a live project.

You are responsible for:

The Software is a drafting and production aid. It does not replace the judgment of a qualified, licensed professional, and it is not engineering advice.

09Updates and Revit versions

While your subscription is active, you get the updates we release. We list the Revit versions we support on our website. We may stop supporting older Revit versions over time. Autodesk can change Revit in ways that affect the Software, and we will try to keep up, but we cannot promise that every future Revit release will be supported.

10Ownership

We, or our licensors, own the Software and all rights in it. This Agreement gives you a license to use the Software. It does not sell the Software to you. Any rights not granted to you here are kept by us.

If you send us ideas or suggestions, we may use them without owing you anything.

11Autodesk and other companies

Autodesk and Revit are registered trademarks of Autodesk, Inc. SunTools is not affiliated with or endorsed by Autodesk. You need your own valid Autodesk Revit license to use the Software.

12No warranty

The Software is provided "as is" and "as available". To the fullest extent the law allows, we disclaim all warranties, express or implied, including warranties of merchantability, fitness for a particular purpose, accuracy and non-infringement. We do not promise that the Software will be error-free, will work without interruption, or will produce correct results in every model.

13Limit of liability

To the fullest extent the law allows, we are not liable for any indirect, incidental, special, consequential or punitive damages, or for lost profits, lost data, damaged or corrupted models, project delays, or design errors, even if we were told they might happen. Our total liability for all claims about the Software or this Agreement is limited to the amount you paid us for the Software in the 12 months before the claim. If you used only a free trial, our total liability is zero.

Some places do not allow some of these limits. In those places, the limits apply as far as the law allows.

14Ending this agreement

This Agreement lasts while you use the Software. It ends automatically if your trial or subscription ends and you do not renew, or if you break this Agreement and do not fix the problem within 14 days after we tell you about it. When it ends, you must stop using the Software and uninstall it. Sections 6, 7, 8, 10, 12, 13 and 15 continue after it ends.

15Governing law

This Agreement is governed by the laws of the State of Florida, United States, without regard to its conflict-of-law rules. Any dispute will be handled in the state or federal courts located in Seminole County, Florida, unless the law requires otherwise.
