atoms/connections missing

[THM Dulli]

Hello,

we have a small(big) problem with our model in ED:

We worked on our ED Model on that day for hours and saved it afterwards without error notes.
The next day when opened the file we get this error message:

1 Compile error: "Set(On2DDraw,[if(
c.DrawFlag,

{--External atom(s) control product rotationas--}
do(
{--Variables for rotationas in order to compensate change of transportation direction--}
RotateCoords(c.DrawRotationas, 0, 0, 1),

{--Variables for translation in order to compensate change of transportation direction--}
TranslateCoords(c.DrawXtranslate, c.DrawYtranslate, 0),

...plus all connections are deleted / many Atoms missing.

Any suggestions? Thank you in advance!!!!



Kind regards,

Hi simulationsgroup,
I looked at your model and it is a problem with the model file itself. At almost line 18000 the file is interrupted and an unreadable format takes over. To better understand what happened can you give more details about what you did? (what version of ED are you using, where did you save, did you use the normal save routine, what OS are you using, etc.)

We are student from germany and we want to simulate a package company.
At our university we use "Enterprise Dynamics 8 Developer" with Windows XP and open the model via "Logistics Suite".
We did save a couple times, at the beginning with "save file as" and afterwards with "save file". Always on same file on a flash drive.

You received our broken model. Many Atoms are missing ("Advanced Transporter", "Condition Control", some "Sources") and ALL Connections. We cant explain how this could happen, especially because the days before it was all fine and we didnt change any saving routines.

Could it be that our model is just too big for weaker Computers/Systems?

[MatthijsJongboer]

The ED save routine has straight forward write-lines in readable text.
I have never heard of the routine being aborted and ending the way your file does. Something seems to be influencing the save routine. There could be numerous reasons for this to happen: Full or limited disk access, speed, file lock or access level (perhaps interfering other programs) or interrupted hardware or viruses.
Most problems are detected before the file write starts. When you use an USB flash drive, select the 'Safely Remove Hardware' in the notification area before taking the flash drive out. The OS will let you know when it's safe to remove it.

We couldnt figure out yet what lead to our problem and it seems that we are the only group with that kind of problem.
Since it was not possible to restore our model and have to reach it in soon we just start over from the broken model. After losing 5h of work we are now more carefully when it comes to the saving; that problem of lost connections and atoms doesnt seem to be an exception and doesnt appear anymore (until now)

However thank you very much and we will consider your tips

[MatthijsJongboer]

I hope it will not fail anymore. Another tip is to continue using "save file as" to have fall back versioning (with different filenames).
