Vista cannot open HLCP.hlp file

VISTA no longer ships with WinHlp32.exe which is required to read .hlp files. Vista users wishing to view these (very common) help files must now download WinHlp from the Microsoft site. This is really a bummer as it seems those that have written extensive .hlp files must now convert them to .html files or package WinHlp32.exe with their setup programs to maintain compatibility.

WinHlp32.exe may be downloaded form here. (Validation of Genuine Microsoft Windows required).

The Parallel Continuous Wall Error

In the example drawing shown above, a Zone has been created where one particular wall has been drawn as three parallel continuous walls.

This is not permissible and will lead to geometrical errors such as shifts in windows, etc as shown in the example drawing above.
