Revit Tools by Avant Leap
Know Exactly What Changed Between Model Versions
Sub-millimeter precision (0.001 ft). Supports Revit 2024, 2025, and 2026.
RedLine compares your host document against a linked baseline and identifies new, deleted, and modified elements across 20+ AEC categories — with color overrides or shared parameter output.
Compares host model against a linked baseline by ElementId — accurate for version comparison of the same file, where IDs are stable across saves.
Detects moved elements with sub-millimeter precision (0.001 ft tolerance). Supports both point elements (furniture, equipment) and linear elements (walls, pipes, beams).
Highlight changed elements in any Revit view using color overrides — projection lines, surface fills, and cut graphics. Eight semantic colors available.
Write NEW, DELETED, or MODIFIED values to a named shared parameter on each affected element — enabling schedules, view filters, and Dynamo downstream workflows.
Three-level validation (Error, Warning, Info) checks document state, link status, category selection, view configuration, and parameter availability before execution.
Full support for Revit 2024 (.NET 4.8) and Revit 2025–2026 (.NET 8.0) from a single shared codebase.
Element exists in the linked baseline but not in the host — added since the baseline was saved.
Element exists in the host but not in the linked baseline — removed since the baseline was saved.
Element exists in both but its location changed beyond the 0.001 ft tolerance — moved since the baseline was saved.
Sub-millimeter precision, instant visual feedback, and actionable output for every coordination cycle.
