What version of Vensim are you using? And new or old GUI?

Can you upload a sample model, as this should not happen.

Can you upload a sample model, as they should be vector graphics (they have been for some time).

Can you upload the model?

Units should be (and are) easy. If you have a level and you have cars in it, the unit should be "cars". If you have people in a population variable, the unit should be "people". If you have a rate such as birth rate, it should be people/year (or per month etc). - For auxiliary va...

I'd like to see an option in the Comment Editor that allows the text in a comment to be included in the documentation. For example, a check box "Document text" to the right of "No cause' so that when selected the comment text appears at the start of the text for a selected comment wh...

No, there is no way to automatically create the stock & flow diagram.

I've got no doubt that you can use both Vensim and Ventity to help. What you are describing sounds like a major project, it's not something that any of us could give you a few pointers to get you going.

Do you really need to export the whole file? You can use a savelist to export just the data you need.

In theory there is no maximum file size. It's going to take a lot of time though to export something that size.

From the wiki page,

Mainstream support for the Embedded Standard edition of Windows 8 ended on July 10, 2018, and extended support ended on July 11, 2023. As of August 2023, 0.35% of PCs are running Windows 8.

You should definitely move to Windows 10.

It's on the control panel (same as old GUI), to the right on the top toolbar.

I don't think Windows 8 is supported any more so it's unlikely Vensim will run on it.

You can try an older version, or even better, update to a supported operating system.

I think that's more or less the best we can do with the newer sketch style.

I'll see if we can adjust things to line up the pipes. But the curves and drop shadows don't seem to be drawn at all.

There is no equivalent. Are you having trouble with it?

You've got some very basic errors in model formulation which is why I suggested going through the tutorial. "Total surface water" should be a stock/level which increases via "Natural rainfall" and decreases via "evaporation". "Evaporation rate" is 36.9 (but th...

Try the attached, press the SyntheSim button to start the sim.

Have you been through any of the Vensim tutorials? I would start with the PLE tutorial at the following page,
http://www.public.asu.edu/~kirkwood/sysdyn/SDRes.htm

This will get you to the point where you can build a basic model. Once you've done this, I'd start again.

Sorry, I misunderstood your first mesage.

No, you cannot do this via the DLL. The DLL will only open published models, so there is no way to get the MDL file into the DLL in order to publish it. You need to run these commands in Vensim via a command script.

You'll need to upload your model for us to be able to help.

It's rare that you even need to use this function, my guess is you have some sort of formulation problem.

Yes, we are aware. There are much bigger problems with the Mac at the moment due to the latest Xcode/SDK.

You'll need to set up a form for publishing, and then us that when calling
FILE>PUBLISH|frmfile

Can you get the sample models working? They should import more than 1 subscript.

View->Export as SVG.

Try changing this to the following and see if it now opens.

Can you please contact us via email at vensim@vensim.com.
