Actions​

  • Navigate To — Navigate to the item in the 3D view (ID_POPUP_ITEM_GOTO)
  • Regenerate — Re-run the stochastic generator for this DFN using the current per-set statistics and spatial model. Position and size samples change unless the RNG seed is held fixed. (ID_DFN_REGENERATE)
  • Grow — Regenerate then grow: extend tips under a default stress field using the propagation engine (step 0.5 m, max 50 m per tip, sigma1 oriented N-S) (ID_DFN_REGENERATE_GROW)
  • Delete — Delete this mesh from the project. (ID_POPUP_ITEM_DELETE)
  • Fracture Intersections — Compute the 3D fracture-fracture intersection line segments and build the connectivity graph (required before topology/connectivity attributes) (ID_DFN_FRACTUREINTERSECTIONS)
  • Mesh Intersections — Intersect the DFN against the visible outcrop mesh and store the resulting synthetic trace polylines on the DFN (used by scoring and synthetic-trace export) (ID_DFN_MESHINTERSECTIONS)
  • Truncate Against Boundary — Clip fractures so that they terminate at the domain boundary instead of extending beyond it (preserves observed P32 on truncated sets) (ID_DFN_TRUNCATEAGAINSTBOUNDARY)
  • Override P32 from Selected Traces... — Measure P21 (trace length per unit outcrop area) from the selected trace polylines, convert to P32 via the stereological factor, and replace each fracture set's intensity. Stores the source mesh name for provenance. (ID_DFN_OVERRIDEP32FROMTRACES)
  • Set Region Mask Source from Selection — Use the selected mesh, trace folder, or fault as a region-mask source for placement biasing. Fractures will be sampled with probability falling off as exp(-d^2/falloff^2) from the source geometry; clears the mask if no source is selected. (ID_DFN_SETREGIONMASKSOURCE)
  • Score DFN against Selected Traces... — Compare the DFN to observed traces and report a match score in 0..1. Combines a Kolmogorov-Smirnov length-distribution test, Fisher mean/K orientation distance, and a |P21_syn - P21_obs|/P21_obs intensity term as a weighted geometric mean. (ID_DFN_SCOREAGAINSTTRACES)
  • Re-derive from Source Orientation Groups — Re-run Fisher and length-distribution fits on the orientation groups originally used to build this DFN, then regenerate. Useful after editing the source groups or adding measurements. (ID_DFN_REDERIVEFROMSOURCES)
