Re: What improvements would you like to see in Vensim?

We are currently coming towards the end of a complete re-write of the user interface. Once this is complete, we should be able to implement SVG without any problems.

Re: Set of initial values for a level with subscripts

The best option would be to put these values in a separate CIN file. You can hard code them into your model (see below), a CIN file will be better in the long run.

Re: use superordinate folders in relative file paths for vensim command scripts?

It will not work without modification to Vensim. We'd need to change Vensim to recursively replace any occurrences of ".." with the parent folder names.

Re: How do I re-activate the View/As Text Option?

Quick question for you as a text mode user. In the development build of Vensim, I've got text mode working. On the toolbar I've added "Check model", "find", "replace", "add var", "Add lookup", and "~~|". Is there anything else that would be useful here? While I'm actively programming this, I might b...

Re: PRO 8.2.1 questions

VPM/VPMX are published models, so are essentially read only which is why you are not seeing the sketch tools.

You will need to contact the author of macro dynamics. They've published it and made the decision to block access to the equations, there is no way to bypass this.

Re: Issue with publishing to web

ok. If you edit
C:\Users\Public\Vensim\COMP\wasm\wasm_compile.bat

and make sure the last line is "pause". Run the compile to web again and the compile window should pause so that you can see the errors. Can you paste the output here?

Re: Reform and clean on save no longer working in 8.2.1

Reform/clean was not really the right thing to do when saving a model, it's more for cleaning up internal memory so we replaced it with something slightly different.

If you click on Model->Settings, there is a new section titled "File Format". Changing the settings here is the best option.

Re: Subscript Selection and loaded VDFX resetting on model re-open

Can you email the model to us?

Also check that you are not storing the settings in a separate file (although that should not matter).

Also, CMD scripts when run from Vensim can load MDL files.

No, that's the only installer (and downloaded many times so far with no issues).

Is your MacOS installation up to date?
