I'm trying to draw a course line on a glass MFD gauge, knowingdesired track and distance to waypoint.I've got a fixed length line that shows the correct direction...How do I go about changing the "height" to a calculated variable,lets say a macro value?Would really appreciate some help with this! :(

					  <Element id="GPS track to waypoint">						    <FloatPosition>241.000,405.000</FloatPosition>					    <Visibility>@GPSWP</Visibility> 						    <Rectangle id="Rectangle">							    <LineWidth>1</LineWidth>							    <Bright>True</Bright>							    <Width>4</Width>							    <Height>120</Height>							    <LineColor>black</LineColor>							    <FillColor>magenta</FillColor>						    </Rectangle>							   <Rotation id="Rotation">							    <Expression id="Expression">								    <Script> @GPSROT 3.1416 + </Script>							    </Expression>							   						    </Rotation> 					    </Element>

Answering my own question... there is a HeightScript identifier which appears to work... so I hope I'm OK,but if there is a better way, please let me know!

..and just in case anyone is trying to duplicate this, be aware that you can shortenthe rectangle by using the HeightScript identifier, but NOT lengthen it..

I assume that you tried this and it didn't work?

<Height>@Height</Height>

Hi,

<Element>
  <Position X="540" Y="480"/>
  <Rectangle Width="2" Height="1600" Bright="Yes" Color="red">
    <HeightCode>(L:segment0,nmiles) 5 * </HeightCode>
  </Rectangle>
</Element>

Gives satisfactory results for me.

Jan that works brilliantly for the FS9 XML schema. I wonder what the FSX XML schema equivalent would be?

This is what ended up working:

<Rectangle id="Rectangle">
  <LineWidth>1</LineWidth>
  <Bright>True</Bright>
  <Width>4</Width>
  <Height>400</Height>
  <HeightScript> ....calculations here </HeightScript>
  <LineColor>black</LineColor>
  <FillColor>magenta</FillColor>
</Rectangle>

Maximum length is 400 and when the calculations produce a number less than 400, the line is shortened.
