[Source] 3d iso vehicle engine

programming
1

Heya Kirupians, here is a little 3d isometric vehicle engine, I hope you’ll like it :slight_smile:

Example : here

Source also downloadable : here

Commands :
Enter- Show/Hide dots
Page Up/Down- Increase/Decrease size
Home/End- Change Y splines level
Arrows- Move
