## What is 3D Engine Auto +?

"3D Engine Auto +" provides information, visualization and working animation on engine 3d and other car mechanisms in 3d. A 3D interactive model helps to visualize the car engine and other mechanisms like "Suspension", "Steering", "Transmission","Differential" from all sides. Models can be rotated, enlarged and panned. 

Features:
1. Enable/disable 3D parts to see the parts which exactly you want to view.
2. Information of each 3D engine parts and other mechanism. The Information is categorized under the following:
a) Introduction of the part
b) Construction of the part
c) Working of the part
d) Material and Dimensions of the part
e) Types of part
f) Other Applications of the part
g) Extra Information related to the part

### 2/5 — Paid version still displays ads.

*2021-06-16, version 1.5*

Paid for ad-free, but ads are still displayed. The ads continue to pop up, so not worth upgrading. When I touch the settings button the app immediately crashes.

### 5/5 — Awesome

*2018-04-26, version 1.4*

Really nicely done! Awesome 3D motion with rotate and zoom features!
