Re: Optimization with wrong subscripts error
I'll see if I can improve the error reporting. Maybe if I just change ERROR: Cannot find constant in model To one of the following depending on what is in the optimization control file. ERROR: Constant not found in model, cannot continue. or ERROR: Constant found in model, but no subscripts in optim...

Re: Feature request: make loop polarity direction indicator vector graphics
The old GUI is no longer supported. The new GUI already does quite a lot more than the old (such as vector graphics).
You can also find a SVG of the image you want, save it to the model folder and use that as an image.

Re: Issue with the name run
I'll raise this as a problem. You could try "Ratio of scrapped car = 0.5.vdfx". Traditionally in Vensim, you don't need to specify the filename extension when running a simulation. For example, you can enter "run 01" and Vensim will create "run 01.vdfx". Vensim searches...

Re: it is frustrating!
You need a custom graph. Open the control panel (button near right of the top toolbar), one of the tabs allows you to create a custom graph with more than one variable.

Re: Unit errors with LOOKUP
Those are actually warnings that you have passed a variable to a lookup that has a unit.
Traditionally, lookups are supposed to have a dimensionless X axis.
The following help entry details what you can do.

Re: it is frustrating!
The graphic tools are "at a point in time", they will not update during SyntheSim.
But you can add a graph to the sketch, that will update during SyntheSim.

Re: publishing a model on a web server
Ther are some limitations to publish a model on the web. It is sais in the documentation that: At present, only the active model view is published. What is the active model view? This is the sketch you are looking at when you click File->Publish to web. Does it mean that if you have ma model with m...

Re: it is frustrating!
It looks like you've maybe saved the model to the root folder on your computer (which isn't allowed). Try saving to your documents folder. Another problem: Tom Fiddeman use an i/o-tool to show a graph. But there is no i/o-tool in the Version 10.1.3. The use of sliders shows no change in the highligh...

Re: Lock tool will not unlock on Mac Sonoma 14.1.1
No, this is the general Vensim support forum.
I think I understand what you are saying, if you click on one of the other icons to create sketch elements, the diagram will be unlocked.

Re: Lock tool will not unlock on Mac Sonoma 14.1.1
1. the lock tool does not 'unlock'. Can you send me a picture of what it should look like unlocked? 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...
