We have discovered a problem when patching V21.29 with v21.30, where some DLL files were not updated. This caused issues with Zone Design Configuration, the tabular management options, and editing geometric objects. We apologise for this.
A new patch, v21.31, has been released to resolve the problem.
Help|Check for Updates should locate the new patch or go to https://www.irricad.com/upgrades-patche ... tandalone/ to download V21.31.
Once again we apologise for any inconvenience caused.
