CREATION NEW OBJECTS

[darkjhesus]

I am creating new diagrams, but, I am getting the error showed in the attached image. How could I solve it?

The demo diagrams are constructed using model objects (those objects that are invisible at runtime but are at the left of the drawing in inkscape). The instruction "copy_xsac_from" is used on new objects to copy the properties from model objects, this way you can change colors and behavior only by altering the model object (avoid altering multiple breakers for example when you have to change some detail). Those errors may appear when the pointed model object is not present in the drawing. If you don't want models, just remove the "copy_xsac_from" from the "Set" tab of objects.
The browser F12 console also can present some error messages for missing tags etc.
If you can't solve those problems post or send me the SVG, I will revise it.
