It's a good idea to have something really simple as default. It could be a simple circle. I don't want it empty because then it will show a failure, not a good first impression when somebody is first installing to try it out.hammax wrote: ↑Mon Mar 07, 2022 2:01 pm ... if I want to create a new Pc_Curve I have to call the macro.
It has already a predefined curve intus. Now comes the formula editing job.
I'm seeking for a start to get an "empty", or the most simple file (only a circle - R, sin(t), cos(t), e.g. ).
Rest can also be done with some (example)-JSON file, opened in the project, copy and paste jobs and later be deleted.
Here is the example that brought me to the recent form of ParametricCurve.

If you toggle New Formula it creates a new formula added to the JSON list. The new formula will contain all the same existing values as the current formula (IIRC), which you can then edit. The interface is terrible, I know. I have some ideas to improve it.
