Version 23.00.005
Released: 18th of November 2024
Known issues:
- This version has a regression displaying some result symbols without their contour lines. (In graphic engine modes other than DirectX they are not visible at all) This is already fixed in published version 23.00.006!
The impacted results are: reaction/connection force resultant, equivalent load, shear center.
Added:

Modified:
- Modify: Documentation module page change is sped up.
- Modify: From now on, when checking the duplication of loads, we also pay attention to the following properties: the comment, the "Apply on the eccentric..." setting, and whether the load is assigned to a structural element.
