I am only changing the format of the file so it loads, any differences between QUCS & QucsStudio are beyond the scope of the converter.
I have looked at the rotated components but can not figure out how it works.
It only converts the latest version QUCS files as that is all I have to test.
If need to convert an earlier version just edit the first line in the file or load into later QUCS & re-save.
Not may people have VB6 , but I will put the code online when it has been fully tested.
As I mentioned JavaScript would be better as it will run in a web browser & is easily modified.
