CADTextData Nodes

Extract and query text data from CAD Links or Imports in Revit without exploding.

The CADTextData nodes provide access to text from linked or imported CAD files using recursive algorithms that work through nested blocks to any depth. This non-destructive approach bypasses Revit's 10,000-element explode limitation, automatically computing geometric transformations for accurate positioning, rotation, and scaling - enabling workflows from creating Revit text notes to extracting survey data for toposurfaces.

FromLayers

Provides rapid extraction of text data from linked or imported CAD files in Revit. The node avoids exploding the CAD instance so it is not restricted to Revits 10,000 element limit.

Features

  • Extracts all text entities from an input CAD link or import (ImportInstance's)
  • Avoids explode so there is no element limit and no need to pre-process your CAD file
  • Works recursively to extract text data from any blocks with nested blocks to n-depth
  • Supports all Revit documents and Families
  • Supports all valid view types, including Section, Elevation, and Legend views
  • Supports shared coordinates and rotations from true north
  • Supports translated, scaled, mirrored and rotated Import Instances
  • Dynamically adjusts units from the CAD file to your display units in Revit
  • Compatible with Dynamo Player
