3D Simulation Software for Electrical Works
Learning creation (production tool) function:

It should be possible to directly create learning materials
for lecture in the slide format.
Should easily create audiovisual materials by insert
images, 3D modeling, video, sound, text, and animation
effects.
The animation function makes it possible to create
materials for step-by-step practices.
3D modeling type parts should be inserted, so it should
be easy to explain the shape and operation method of
the actual components.

Theory study function :
Easily learn about electrical circuits through essential
data on basic circuits.
It should provide the same questions and drawings from
the previous electrician qualification tests (total 7 test
examples), thus increasing the adaptability to your test.
