Unfortunately I can find the SDK on the MS web site. Maybe it will turn up in due course. bones -----Original Message----- From: jhb_airlines-bounce@xxxxxxxxxxxxx [mailto:jhb_airlines-bounce@xxxxxxxxxxxxx] On Behalf Of FrankTurley@xxxxxxx Sent: 21 October 2006 17:13 To: jhb_airlines@xxxxxxxxxxxxx Subject: [jhb_airlines] Re: FSX XML gauges In a message dated 21/10/2006 16:57:19 GMT Daylight Time, bones@xxxxxxx writes: Sounds like the Ace tool, once mastered, is a lot better than trying to build gauges in Notepad!

I'm not too concerned about that because once you master the ACE tool and the absolute minimum requirements for a gauge to display, you can easily copy the guts of the existing code (i.e. the display string) straight into a working template. This is true for the digital gauges I'm working on for my MiniPanels, I guess your projects would be more complex. Nevertheless, breaking the project into single elements should make gauge building and maintenance a lot easier. As you say, much easier than Notepad! Frank T.
