Hi Terry, You *were* opening the latest “code”, you just didn’t have access (I assume) to your latest parameter changes because you didn’t save them as a preset. I think the OpenSCAD separation of “initial conditions” from the execution of the code is very clever and useful. I support multiple people with the same code and just change the initial conditions appropriate for them so I can return to them at any time in the future. I just wish there was a way to save the current preset as a separate json file. Then I could email the client their own settings in a convenient form and they could reproduce what I’m doing. I had never used Notepad++ before, but when I first started using OpenSCAD I read that that was the recommended code/text editor. It supports language specific text formatting, which I’ve come to rely on heavily, and a tabbed interface to have multiple documents open. My program uses multiple code documents.

Of course, as a beginner I see Customizer from a different angle to that taken by a developer. I was pleased to be able to modify parameters so easily. But after a succession of these (some followed by actual prints), i wanted to open the latest code for further learning and editing. So I was baffled why the code remained unchanged since I’d downloaded it. And my changes were unavailAble in a SCAD file! From discussion here I now gather that is by design, although I remain somewhat unclear why. Also, could you explain what advantage stems from bringing my text editor into the workflow please?
