IfcOpenShell 0.7.11-alpha240829

fcOpenShell is an open source (LGPL) software library that helps users and software developers to work with the IFC file format. The IFC file format can be used to describe building and construction data. The format is commonly used for Building Information Modelling. IfcOpenShell uses Open CASCADE (the Open CASCADE Community Edition) internally to convert the implicit geometry in IFC files into explicit geometry that any software CAD or modelling package can understand.

0.7.11-alpha24080514 Sep 2024 08:05 minor feature: See #5087. See #5114. Skip trying to test shapes that obviously don't have a representation to prevent false positives.
0.7.9.24070304 Jul 2024 22:45 minor feature: IfcWrap CMake - migrate to FindPython Previously it was giving deprecation warnings: CMake Warning (dev) at /IfcOpenShell/src/ifcwrap/CMakeLists.txt:38 (FIND_PACKAGE): Policy CMP0148 is not set: The FindPythonInterp and FindPythonLibs modules. are removed. Run "cmake --help-policy CMP0148" for policy details. Use. the cmake_policy command to set the policy and suppress this warning.

0.7.9.24062728 Jun 2024 02:25 minor feature: When upgrading to IFC4X3, preprocess the file to remove de precated style assignments.
0.7.9.24061415 Jun 2024 06:45 minor feature: See #4854. Don't show IFC mode UI if there is no IFC model. Still quite a bit of work to be done here, but this is better than nothing.
