The G-Electrical Plugin has a dedicated Knowledge base, available here:
This knowledge base is divided in different sections:
Tips and Tricks
Reports and Export
That will help you taking advantage of all the product features available.
With the same objective, you have the G-Electrical E-book “Creating Electrical Designs”, that will guide you through the product functionality, and how to use them/the workflows involved. The E-book is designed to be used without the presence of an instructor, so it is a step-by-step explained content that requires only a little CAD experience.
You can download the E-book here: G-Electrical - E-Book.pdf
In the Graebert Youtube Channel, you can also find a video showcasing the product's functionality (https://www.youtube.com/watch?v=DX3apjf49po).
