Maptek Vulcan Extents Problem

I was having dinner with some friends tonight and, being the nerds that we are, conversation turned to work and Vulcan software. The crux of the conversation was Vulcan errors that we had all made. One mistake seemed more prominent than others.

In my time supporting the Vulcan software, both with Maptek and even after, one common mistake eventually confuses most new users of the program. The extents mode creates a fundamental change to the way that Vulcan is displayed and most people don't even know how they turned it on let alone how to turn it off.

What happens is this:

The user thinks that a word processing program is the active window on their computer but in reality Vulcan is the active window. As they begin to type the buttons they press aren't creating words in a sentence, they are activating hotkeys in Vulcan. Most of these hotkeys activate things that are rather innocuous (a timer since last refresh or a rotation dial) but eventually the 'E' button (the most used letter in the English language) is pressed.

The 'E' hotkey activates the extents mode in Maptek Vulcan. This puts a box around the extents of every object on the screen. There are often so many box lines on the screen that it is difficult to see anything else.

Because the user doesn't realize what created the error, they have no idea how to turn it off. I have had people approach me in a panic over this and it is so easy to fix.

Next time your Envisage window blows up with thousands of boxes and random lines, try pressing the 'E' key.
