• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

Taxiway to Runway Junction II

I am trying to follow older advices given in this thread (post no 12) http://www.fsdeveloper.com/forum/threads/taxiway-to-runway-junction.426452/

That is, to use CLOSED path to draw the centerline of the junction.
In all cases, the CLOSED links are defined with "Draw Surface" and "Draw Detail" Unchecked and "Centerline" checked. While normal TAXIWAYS have "Centerline" Unchecked.
Nevertheless:
  1. the surface of the CLOSED path does get drawn (except in one trial, in which centerline was not drawn although checked!)
  2. when the node of the CLOSED path is very close to the node of the normal TAXIWAY, unpredictable results occur (centerlines are drawn from TAXIWAYS, although unchecked, or the centerline of the CLOSED link is drawn only in the straight segment).

Can you please help with this?

I attach the wip .ad3 file. See the exit just next to rwy14 threshold.

PS: please also see how the taxiway side lines gets drawn on the runway> Is this normal, or is any way to fine tune it (so the side lines stop at he runway?)

One thing to be aware of is that ADE does not draw taxi markings very well at the moment so the only real test is how things look in FS. I hope to re-write the entire path drawing code over the next few weeks.
 
For the last question you can add a node at the runway's edge and choose no line for the segment on the runway. But check a satellite image to make sure you need to do that.

To draw only lines, I use an Apron Path. If it is not connected to the rest of the taxiway network, it will not be affected by other lines nearby.
 
I offset the runway link black line a bit, so the taxiway side lines end at the runway edge line.
Finally, I used PATH lines to get around.

It seems that:
  1. "Draw surface" is not respected (i.e. when CLOSED links are used, surface gets drawn, regardless the switch).
  2. overlapping nodes (when the center -black dot- is within the ADE color circle of another node) can produce unpredictable results.
Are these two points confirmed (so we don't ask the same questions in the future)?
 
#1 probably depends on the sim, but I can't remember exactly.
#2 is true.

Note that the AI aircraft will follow the black line after slowing to taxi speed, so don't offset it too much.
 
Taxiway DrawSurface flag status is ignored by all sims except Prepar3D v2. ADE uses proximity tests to determine if a user intended to link nodes to nodes or nodes to links etc. That is there is a small test distance and if two elements are within that then ADE will assume the user wants to make a link. So if a node is placed close to another then they may join. Note this does not apply to moving one node over another. So if you want a deliberate break then you should place the nodes some distance apart to defeat the proximity test and then drag one over the other. This is why you might consider the results unpredictable.

That is what I do.
From what I see, if you place the center dot of a node within the colored circle of another things can go bizarre (as noted in OP, point 2). Of course, this is a FSX issue; nothing to do with ADE.
