Anyone made something in Excel to draw schematic of a network?
Eg. You're supplied with a list of nodes, and a list of connectors
that link those nodes, for a pipeline network, and then VBA takes this
list and draws it in Excel.
My intention is to draw the nodes on the Excel grid (by pasting in pre-
drawn ones from a hidden 'library' sheet, rather than using the
'drawing toolbar'.
I'd be interested if anyone has any tips or advice.
Thanks in advance,
Regards,
Mark
