How are the editing features for embroidery on Husquvarna viking Topaz 30 on the machine. Know it is not touch, is it easy to edit. Can someone explain in detail?

The pdf Features and Benefits (from the Husqvarna website) has the following onEditing:

DESIGN EDITING – Customize your designs
on-screen with just a touch
• Mirror, rotate, and scale designs to suit your
needs
• Cancel color stops to sew one color and tone-on-
tone embroideries.

I have no idea if you can rotate by degrees or just 90 degrees at a time.
For anything else you'll need 5D embroidery (plus) or any other software.

Sorry, I can't but I will push your question back to the top and perhaps someone will come along with some help. In the meantime, try looking here, perhaps under explore the machines.
