# 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
