## What is ENGINO kidCAD (3D Viewer)?

ENGINO is perhaps the only construction system that originated directly from Education. Originally inspired by teachers for the Design and Technology classroom, it evolved to an award winning product which covers from Structures to Mechanisms, Renewable energy and even Robotics Control.  The patented geometry of the ENGINO components allows connectivity to all directions of the 3D space with a simple snap-fit method, making it very easy even for children at the age of Primary Schools to build complex models. The 3D model viewer application has been created to allow easy access to new models developed by the ENGINO team and gradually the users themselves. All ENGINO sets have printed step by step instructions for the main models but many additional models can be created. With the new generation of technology where smart phones and tablets have become a part of every-day life, it is essential to enable the users to see new model ideas on these devices. The model viewer has an extensive library of models, continually updated, from cars to motorbikes, planes, helicopters, trucks, cranes and many more! The user can select which model to view and once this is loaded to the application, then the user can rotate the model to see it from various angles, he can zoom in to observe connecting details and most importantly he can explode the model and see how each part connects to the other one.

### 1/5 — Does not work on iPhone

*2026-05-31*

It’s May 31, 2026 and just downloaded the app but it doesn’t work with iPhones. The app opens but it just shows a wheel spinning but never actually loads.

### 1/5 — Nuke this app now!

*2026-05-27*

it’s pretty good BUT u only gave me 5 times to use it! like then u made me make a idiotic account in this stinking app. And when I clicked it,it said access denied! Fix this or i sue u! also the instructions it stupidly glitching like crazy and I got i headache because of this trash. If ya fixzit I will rate it 5 stars.

### 1/5 — Incorrect instructions

*2026-04-18, version 9.7*

Horrible instructions. It’s out of order, having to repeatedly pull apart the model to install a piece that should’ve been placed 5 steps ago. It’s missing steps altogether, and it’s got wrong instructions. 
Only a lifetime of LEGO and gundam allows you to build it in a reasonable time.

### 1/5 — Does not understand

*2026-02-16, version 9.7*

Putting a combination that does not fit

### 1/5 — Do not buy

*2025-10-20*

Instructions for kits are ONLY available through this app, which requires internet access and compulsory registration. Thee is NO OTHER WAY to get instructions - even the “download PDF” button in the app doesn’t work, it just downloads an empty file. This is for a hands-on building kit - the app should never have existed, much less be required for an offline, no-electricity-required toy!

### 4/5 — BEST BULID

*2025-07-09, version 9.7*

The Chinook double blade helicopter I built is amazing.
The app itself is awesome because it is 3d enabling you to spin it round while building. I still haven’t explored the app enough but it is wonderful and all the projects are worth the money.

### 5/5 — I love it I you're haters hate you be not me I love your game I listen to the haters

*2025-06-29*

I love it

### 1/5 — Trash

*2025-01-25*

This app is utter garbage. As an engineer with experience with Fusion360, this app is just a waste. LEGO has a much better interface for building their kits. 

Not only are these CAD drawings/blow ups not complete, the assembly is almost always in the incorrect order that requires you to remove parts just to put another part in the middle. 😡 while building the physics laws sharpening wheel, the completed CAD solution was nowhere near the complete picture on the box. 

Amazing idea, TERRIBLE implementation.

### 1/5 — These instructions are absolute garbage

*2025-01-07*

There are no instructions in the box and you are required to use the app. The order of the instructions in the app make no sense and you need to put pieces physically through other pieces, which is impossible. Which is sad since this is a physics product.

### 1/5 — Stuck Authenticating

*2025-01-02*

After I log in “successfully” it just sits authenticating…its useless
