# A change log of the ifc2ca files
|
|
|
|
## 01/03/21
|
|
|
|
- Add salome and code_aster script files for a "bonded" case, meaning all connections between elements are considered fixed. This allows to consider exported ifc files from commercial software that do not include connections between surface elements (see building_02 example)
|
|
|
|
## 14/10/20
|
|
|
|
- Add curve connections between elements and as supports according to the defined orientation - stiffness is not yet considered
|
|
|
|
## 17/08/20
|
|
|
|
- Add rigid links for point connection to elements
|
|
|
|
## 14/07/20
|
|
|
|
- Add internal springs for point connection to elements according to the defined orientation
|
|
- Add external springs for point connections according to the defined orientation
|
|
|
|
## 27/05/20
|
|
|
|
- Add orientation for point, curve and surface geometries
|
|
- Calculate final geometry and orientation based on object placement transformation
|
|
- Add warnings in the json file to show any corrections considered while parsing the ifc file from ETABS with a model with rigid links
|
|
- Reduce file size by adding material and profile db in the json file and referencing them in the element objects
|
|
- Implement internal releases for curve-to-point connections with any arbitrary orientation
|
|
|
|
## 22/03/20
|
|
|
|
- Calculation of section properties for I symmetric profile if not provided (assuming fillet radius is zero)
|
|
- Added geometry of planar structural surface members
|
|
- Refactored the ifc2ca.py script
|
|
- Added support for rigid links
|
|
- Added advanced meshing script to correctly simulate connections and independent meshing of structural elements (no common nodes)
|
|
|
|
##### 26/02/20
|
|
|
|
- Changed section to profile and added I profile
|
|
- Modified material and profile schema with mechanical and common properties
|
|
- Added geometry identification for point connection from representation
|
|
- Added connections along with supports based on the number of elements a connection is applied to
|
|
|
|
##### 09/02/20
|
|
|
|
- First implementation for straight structural curve elements and point connections
