Re: Lock tool will not unlock on Mac Sonoma 14.1.1
It's working fine for me. Are you using an existing packaged model? Packaged models are read only (so the sketch is locked). If you are not using an existing packaged model, what happens when you click one of the sketch tools (such as "move", the tool to the right of the lock sketch button).

Re: Model view adjustments
Can you upload the model?
Also please provide details on what operating system you are on, and the exact version of Vensim.

Try option (Mac) or ALT (Win) and up/down, that should do it.

Re: Vensim training

Re: Can the Vensim PLE version achieve seasonal forecasting?
Start by adding units to your model. I would not bother simulating or doing anything else until your model passes this basic quality check. I can immediately see a problem (you've got a variable called month).

Re: Vensim training
For the system dynamics model that I am working on, I am using the Vensim Professional license. However, I would like to start with the automatisation of runs, parameter tuning etc. Is it true that this is not possible without the Vensim DSS license? Can you explain what you mean by this?

Re: Units tips or laws
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...

Re: Utilizing Ventana Systems Tools for enhancing data breach protection strategies ?
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.

Re: Cannot run Vensim after install
From the wiki page,
You should definitely move to Windows 10.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.

Re: Cannot run Vensim after install
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.

Re: Export as SVG not workingn correctly for new sketch style
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.
