From 6dba78d6b9c40432927ef90f874cfc9da6ec2682 Mon Sep 17 00:00:00 2001 From: jfa Date: Tue, 29 Aug 2006 14:57:56 +0000 Subject: [PATCH] PAL12470: Cannot use boolean operations on COMPOUNDs and COMPSOLIDs. Workaround OCCT limitation, performing boolean operations on sub-shapes and then gathering results in a compound. --- src/GEOMImpl/GEOMImpl_BooleanDriver.cxx | 193 ++++++++++++++++++++---- 1 file changed, 161 insertions(+), 32 deletions(-) diff --git a/src/GEOMImpl/GEOMImpl_BooleanDriver.cxx b/src/GEOMImpl/GEOMImpl_BooleanDriver.cxx index a0ae0bc0c..ca0812c39 100644 --- a/src/GEOMImpl/GEOMImpl_BooleanDriver.cxx +++ b/src/GEOMImpl/GEOMImpl_BooleanDriver.cxx @@ -1,36 +1,42 @@ // Copyright (C) 2005 OPEN CASCADE, EADS/CCR, LIP6, CEA/DEN, // CEDRAT, EDF R&D, LEG, PRINCIPIA R&D, BUREAU VERITAS -// +// // This library is free software; you can redistribute it and/or // modify it under the terms of the GNU Lesser General Public -// License as published by the Free Software Foundation; either +// License as published by the Free Software Foundation; either // version 2.1 of the License. -// -// This library is distributed in the hope that it will be useful -// but WITHOUT ANY WARRANTY; without even the implied warranty of -// MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
