Problem After SP1 Installation

[MatthewS]

I have attached what I believe to be everything an intrepid extrusion engineer needs for their latest civil engineering project. Even with a fancy readme to tell you what is what!

Thank you!

Well FSX KML 1.09 now supports ExtrusionBridges!

Here are a few screen shots... I need to do a little more work on 1.09 and I'll upload on Sunday some time.

BTW bridges can be landed on too!

Hi, Mace

I think it's a great new feature of FSX to have the extrusion bridges in the sim now.QUOTE]

Do you refer to the new SP1A upgrade?
Wasn't it possible before?

No I was referring to FSX. Sure we could do extrusion bridges before SP1.

Which is the new tool to help creating extrusion bridge, please?

I believe they are made using the ExtrusionBridge command in xml, and run thru bglcomp. I have not made one yet though...I have not had the need...been doing all airport scenery lately.

Of course, I guess at an airport, if you had a bridge going into it, an Extrusion bridge might be in order! I'll have to look at that. MPTO has two freeway bridges going into a parking area.

According to the SDK these extrusions bridges can also take traffic (ie Freeways).

I guess this means you can create properly elevated freeway intersections where traffic from one freeway passes overhead the traffic below.

Amazing!

Hello,

What is the exact path to these SDK documents? I have it installed but which folder contain such documents? Maybe a silly question but I would like to pin-point it.

Thanks,

WoW!! I am looking forward to especially because by freeway traffics built for downtown area in Chicago still refuses to show up though placed in the Addon Scenery/Scenery folder (by clicking "Build" in FSX_KML v.1.7).

Later I also tried to activate the Addon Scenery in FSX but still no show.

Maybe I have to re-build everything from scratch.

PS. There's also a file that I had downloaded from Avsim intended to get rid of the trees at Belize Int'l airport. But now, after installing
SP1, it no longer works. Now, the jungle reigns there. But I an hopeful!....



NEW EDIT (5/20/07): Finally I got all my KML built freeway traffic back! But for that I hat to create a folder in Addon Scenery: e.g. Downtown Chicago Traffic/Scenery and then added it to the library in FSX settings.


Matthews, THANK YOU!!!

Be forewarned, I had a monster of a time getting a simple straight, one span bridge to display its pylons. My code was flawless and the ever helpful Doug Matthews uploaded the xml of an extrusion bridge that was known to work. Standing on the shoulders of giants, I was able to crack this extrusion bridge thing wide open, but honestly I haven't probed the depths of what can be done. Heck, i haven't even deviated from the concrete deck and pylons that his example XML used. Perhaps later tonight I will get more daring.

Bridges can and do easily carry traffic. For example, I don't know the height of the real Bonner Bridge, other than the hump for boats to pass under is 65 feet. I put a line of traffic on it to visualize how tall it "should" be because I know what it looks like from driving across it a few times before. I figured I could use the cars to see if it looked right. And there were my cars, happily driving along. But it might be to ready to accept traffic. When learning from the master XML I received, I modified the height of the bridge so I had two that followed the same path stacked like a double deck bridge. All the traffic flowed across the top deck.

By pure chance last night, I was flying the famous River Visual approach to DC's Reagan National and spied an odd behavior by traffic encountering an exclusion bridge (it MIGHT have been a library object bridge, and I will investigate later). If you fly directly north along the Potomac out of KDCA, you'll eventually come to a 90 left hand turn in the Potomac. There will be a large island right before the turn. The bridge here, the Francis Scott Key Bridge, has the George Washington Parkway passing underneath it on the southern/western bank of the river. The GW Pky has traffic on it. But when it encountered the bridge, cars were making a 90 degree vertical turn and climbing the side of the bridge, then going back down the other side. I will attempt to obtain a screenshot of this, as well as maybe trying to make my own set of crossing bridges with traffic. This link http://maps.google.com/maps?f=q&hl=...76,-77.072439&spn=0.025682,0.057335&z=15&om=1 should provide you with the exact location of the bridge, if you want to see it for yourself.

The behavior you witnessed on the GW Parkway is due to the traffic system's ground elevation query hitting the platform in the bridge.

Thank you!

Glad to have helped

Ok that makes sense I guess. I assume this means that its not possible to make a bridge that passes over a road with freeway traffic on it.

Not in FSX (unless your extrusion bridge specifies to suppress platforms).
