Some tools like Line Offset, Stretch by Polygon, Delete a Conline do not refresh after the tool has finished executing. So it appears that the geometry was not added or deleted.
Users will experience issues like construction lines remaining after being deleted, lines not appearing after doing an offset or other instances where the function of a tool doesn't return the expected result.
A patch will be provided. Run the patch setup and the original 12.1.1 version will be updated. Obsoletes ArtiosCAD 12.1.1 bld 960 and ArtiosCAD Enterprise 12.1.1 bld 60.
ArtiosCAD 12.1.1 bld 968 and ArtiosCAD Enterprise 12.1.1 bld 72 are the versions which address the issue.
The workaround is to invoke a refresh operation (F2, mouse wheel), CTRL+D (or scale to fit) or just select another tool.
