- Will my old subscription still work?
You bet! All Vitruvius subscriptions will be grandfathered in. Existing users will not notice any change in features or loss of access.
- How much will Legacy StruCalc cost?
Legacy StruCalc will be available at the same price, and is included in the 'Plus' and 'Pro' tiers. The pricing tiers are subject to change, but existing users are guaranteed to be grandfathered in and get the best deal.
- How can I get access to the new retaining wall module?
To get first access to retaining walls, make sure you have a Base II or III subscription before the launch. After the launch, your subscription will automatically be renamed to "StruCalc Pro" and include every feature available—including retaining walls!
- What about advanced features like shear walls?
Shear walls, concrete and masonry beams, linked loads, and all the other Vitruvius features you've come to rely on aren't going anywhere. These features still aren't included in the legacy StruCalc platform, but no one who currently uses Vitruvius will lose access to any features they currently have access to.
