Summary	0031144: Shape Healing - ShapeAnalysis::OuterWire() infinite loop on solid obtained from IFC

Revision	2019-11-13 08:36 by abv
Description	BRepMesh hangs on one of solids created during reading from IFC with OCC reader. This blocks any possibility to see the model in CAD Assistant or other OCCT-based viewer. This is regression appeared in OCCT 7.4.0. The solid is valid according to checkshape but has large tolerance (90 mm, on object of ~ 300 mm size) and visible gaps in edges + misplaced vertex, see attached image. The IFC files comes from Duraark archives (http://duraark.eu/data-repository/ [^]), archive "A-House Scan September 2014" (https://tib.eu/data/duraark/BuildingData/03_IFC_E57/LTU_A-House_2014-09-25_ifc.zip [^]), file LTU_A-House_redesign.ifc, solid 4081 (no information on original entity).
