Release notes for the AEC.codes QTO add-in. Newest releases at the top.
0.9.0-beta.580 — 2026-09-06 Public Beta 2
What's new
Bill of Quantities (BoQ) Excel export — a new export format with configurable, ordered section grouping, free tier.
Unified grouping control in the Export Preview window: one ordered list now
drives BoQ sections, XPWE hierarchy and flat-Excel WBS columns consistently, replacing two
separate controls that could get out of sync.
Export Preview now remembers your last-used output folder across sessions.
All export format checkboxes now start unchecked when Export Preview opens, so you always choose explicitly.
New Reload button on each price list in QTO Setup — re-imports from the original source file without reopening column mapping.
The price lists grid now shows the source format/file for each price list.
New categories: Rooms, Areas and MEP Spaces can now be tagged, computed and
exported like any other category (Areas are correctly excluded from volume calculations;
zero-quantity spatial elements, e.g. an unenclosed room, are flagged rather than silently dropped).
QTO Tag: adding a shared item to several already-tagged elements at once is now additive — it no longer overwrites each element's existing data.
QTO Tag now warns when a selected element's category will never produce a computed quantity, instead of letting it silently disappear later in Compute/Export/Report.
Fixed
A data-loss bug where editing a shared item across several already-tagged elements could silently fail to save the change on some of them.
QTO Tag could fail to open entirely for certain selections.
The category list did not scroll in the QTO Compute Preview/Results windows.
MEP Spaces were sometimes misidentified in export/report output and in the tag parameter list.
The "Delete price list" dialog no longer promises a behavior (orphan-flagging) that doesn't exist.
The data-source picker in QTO Setup no longer offers dead-end options.
The feedback/bug-report button now opens the web form correctly instead of an email client.
Revit 2027 removed from installer targets — it was never functional (different .NET runtime) and is now cleanly excluded.
