Re: TaxiLines

Recommended Posts

When I use TaxiLines I get a 'ghost' line of lights about 50 ft below (south). Anyone else had the problem?I first got this with build 149 but it has continued in build 152 despite a 'fix' mentioned in the update files.Any help would be appreciated.Peter Leadbeater,Air Pierre, Warrington, UK.Peter Leadbeater,Air Pierre, Warrington, UK.

Hi Peter,When I look at the code it seems a bit too much to me. Are you sure this all belongs to the taxiline?When I for example make a taxiline using the new command the code looks like this:[tt]; Taxi Centerline Area( 5 00:0.04265 000:0.09217 10 ) LayerCall( :Taglayer 40 ) Jump( : ):Taglayer RefPoint( 7 :TagPoly .3 00:0.04265 000:0.09217 V1= 33333 V2= 833 ) TaxiMarkings( CL -1353.3332795567 -1879.99992529551 CL 63.3333308166929 -1463.33327518569 CL 896.666631036336 869.999965429307 CL 396.66665090455 2469.99990185102 BREAK ) :TagPoly ReturnEndA[/tt]I see you also have some road and dot commands that are not needed anymore. I think that is the problem.Arno

I suspect the road is his taxiway itself, but I agree, the dot commands are not desired.peter, I don't use Airport, so I'm not sure what its doing, but I'd take the dot commands out, just delete that whole section, and recompile, at least as a test. Then see if its what you want.Perhaps that's what Airport thinks the night lights should be. Bob

If you're using the taxiline menu, with at least one bend in it, this appears to happen. At least, it was the only way I could replicate what you show in your message.This should be brought to Tom's attention.In the meantime, as a work around, use the Polygon menu to construct the taxiway, and the "Create lines and lines of objects" menu to lay a daytime yellow centre line which shows green dots by night. This "line" menu is pretty straight forward. The construction of the taxiway with a polygon requires a bit more work when compared with the built-in menu that you are now employing, but it isn't hard. I have been making taxiways with polygons since I began with Apt program.

Arno,I just realised that I put the wrong piece of code with the wrong picture. However the principal is the same!Other Guys,Thanks ever so much for the responces.I will give the other things a go tommorow - but regretfully 'Build 153' hasn't solved the problem either :-((Peter Leadbeater,Air Pierre, Warrington, UK.

Not had a lot of time over the last few days but I have found there is a definate problem with the 'Taxiway' feature of the 'Road' object (even in Build 153).When you click for 'Add Centerline Lights' and 'Add Centerline Stripe' it creates a piece scasm code for using the 'TaxiMarkings' call and a leader 'CL' to each of the locating numbers. (See the code earlier in this thread for the example).These numbers are not the same as the line itself and cause a 'ghost'. Seems though that if you set these values to the ones for the line then the 'ghost' moves from below to above the correct taxiline.The 'Dots' command isn't required if these numbers were in the correct relationship. I suspect that deep in SCASM (or Airport) the 'CL' call is where the problem is as well as the 'Dots' commands being provided when not required.Hopefully someone gets the idea of the above (please excuse the terminologies!) and can sort things out for the next build?Peter Leadbeater,Air Pierre, Warrington, UK.

Hi Peter,I have not tested it, but when I look at your source I see that the scales of the RefPoints are different. So I guess that is why the coordinates for the TaxiMarking and the Dots are not the same. Apart from some rounding effects I guess the coordinates are the same.Arno

Arno,Just to clarify - the source code was not mine but that generated directly by Airport 2.6 Build 153!The RefPoints in the Centerline section are shown without a zero on the end i.e. -2850 in the 'Road' section is shown as -285. If you add the zero to the end of all the RefPoints following the CL call then the 'ghost' moves to the North of the orginal rather than the South. I cannot seem to get a set of RefPoints in the Centerline section that overwrite the proper taxiline?!Peter Leadbeater,Air Pierre, Warrington, UK.

Update:Thanks to Tom (of 'Airport' fame!) this problem should be resolved by the release of Build 154 which, if all goes to plan, should be available from the support site over this coming weekend.Thanks to Tom, the development team and all contributors to this thread for their help and assistance.Peter Leadbeater,Air Pierre, Warrington, UK.
