This release focuses on flow — multi-select actions across Project Overview and Library, persistent filters that remember you between visits, an inventory that holds its place, and a handful of long-awaited fixes for special conditions and the AI Assistant. Let’s dig in:☑️ Multi-Select Actions on Projects and Library
We’ve added a proper Selection mode to both Project Overview and the Library.- Select multiple projects or library items at once
- Apply actions in bulk instead of one-by-one
- Works across both views with a consistent UX
💾 Filters That Remember You
Project Overview now remembers your filters between visits. No more manually hiding “On hold” and “Archived” projects every time you open the platform — your selections persist across sessions.A small change, but one that adds up fast when you log in several times a day.🧱 Collections in the Constructions Library
The Constructions view in the Library now supports collections, just like the Materials view does. Organize your assemblies into the same logical groupings you already use elsewhere — no more switching mental models between tabs.🧭 Project Navigation, Refreshed
The in-project navigation has had a visual and structural refresh — cleaner hierarchy, clearer active states, and faster orientation when jumping between dashboard, inventory, and report views.📋 Building Component Inventory Keeps Its Place
The Building Component Inventory now preserves your expanded state and scroll position during normal use. Click into a material, hit back, and you’ll land exactly where you left off — no more re-expanding the same tree for the fifth time today.🗺️ Map Shows Your Location First
When creating a new project, the Location step now uses your browser location to show a map centered on where you are — instead of a blank page until you start typing an address.🔄 SI Agent Mapping Updates Live
When the SI Agent maps or remaps a material, the inventory now updates automatically — no manual page reload required. Mapping feedback is instant.🇸🇪 Resurs-ID on Boverket Data
Swedish Boverket materials now carry their Resurs-ID as the declaration number — making it easier to trace EPDs back to the official Boverket database entries.🇮🇸 Iceland: Corrected Installation Input Units
Adjusted the installation input denominator unit for Icelandic calculations to match the correct reference. Small change, correct results.✏️ Smaller Touches
- Decimal values are now allowed for number of persons during project creation (no more “you must enter a whole human”).
- General user feedback messages and toasts have been polished across the app.
🐛 Bug Fixes
- 🧮 Fixed a bug where adding a special condition caused total emissions to increase instead of decrease. Yes — wrong direction. Now correctly subtracts.
- 🧱 Fixed a bug where the special condition (S) button disappeared when a construction was dropped onto a parent/collection row in the inventory. Drop where you like — the button stays.
- 📐 Fixed an issue in Speckle quantity extraction (mængdeudtræk) that produced incorrect quantities on certain models.
- 🤖 Fixed the AI Assistant crashing with “Stream error occured” for some users.
- 💾 Fixed a bug where users were unable to save constructions in certain projects.
- 🪟 Fixed white-background text blocks appearing inside info modals, breaking the visual consistency of the modal.
This release leans heavily on community feedback — persistent filters, the inventory state fix, and Boverket Resurs-IDs all came directly from you. Keep it coming via community.realtimelca.com — we’re listening.Read the full post →
