I know I have done this fine on previous versions. But.... I have made 3 tracks in an area and wanted to use the MAKE A NETWORK option. It runs then errors about halfway with the following error...

I have tried using each of them individually but it get the same error??

Yeah, I've had this problem off and on as long as I remember. Same spartan log message as you get. I find that restarting Windows (not just TF, the whole computer) sometimes helps, but not always. Some tracks just won't convert. I'll send one in.

This evening I went back to my old tracks to make sure I was not dreaming and all of them work fine ...

Hmmm I may have discovered a repeatably problem... Â

'> Looks like it is related to the first few track points.... This first picture gets the error...

and when I move the first point down so it does Â not cross the trail like this...

It makes a network just fine without a problem....
It seems to be related to just the beginning of the trail.... Because, and don't laugh Â ':p'

Â SInce I was having problems locating this cache, I went in circles a few times ... this one one makes a network just fine...

I also got the violation... but I didn't restart winders, just TF.

Ran the same network trails again, and also got it.

I tried moving the top listed track down the list (remove & re-add), it was actually right in the middle of the network, and re-ran and it worked.

I looked at the TF log, and it shows a DirectX error right after catching the violation.. speciafically:

DirectX Error [2405]: Access to this surface is being refused because the surface is already locked by another thread.

I saved the log if anyone wants it?

Scott will have to take a look at this, he wrote all the network code. He's out riding the Arizona trail currently. He should be back in a couple weeks.

I read this post today, as I was having exactly the same issues. I was reassembling a single loop from a series of walks that covered much of the same ground. So I had to cut out lots of duplicate tracks resulting in occaisional breaks in the original loop. Before using the "make network" to stitch these segements into one continuous loop, I went back to make sure that no lines intersected. All the segments were touching, and there were not cross-over points. But still "make network" barfed, as described in the previous posts. Something is too unstable in this function...

Try changing the order of them (segments) in the list.

Worked for me.... least, this time.
