He hates Autocad....not really...Part 2 of Excel to Autocad

I showed my PLC Excel application (see my previous post) at work , and the man said, yes, it had promise. As usual, someone else said "The address numbers are not right!" Ok.

So here I have wasted another sunny day (actually, if I go into the sun here in NZ for more than 15 minutes, I get burnt) fiddling with this stuff.

I have done a few changes, mainly the buttons that were embedded in the spreadsheet have now been transferred to a User Form, this is activated by the Quick Access menu. It just allows the user to scroll up and down and get the buttons to show only when necessary.

The range of equipment is now light, relay and solenoid valve. The silly idea of having each line drawn has been ditched in favour of block that just gets inserted.

The existing drawings like to tell the viewer that this is an "alarm light". Which seems extra work when you have a symbol that conveys that information. Same for the solenoid valve.

I did toy briefly with the idea of downloading the IEC 6017 electrical symbols. Yes, you can, but they cost. I had some doubts as to the snapping I should be using, but I figure if this all goes ahead and someone says they want 2mm snaps instead of 1.5mm, then it would not be that horrible to change.
