Model Constructor 3D1.2.1

MC3D is a plastic modelling simulation app for your smart phone and tablet. Put together a variety of realistic models part by part and have fun learning about how these parts form the complete model.

Featuring a very straightforward part drag n' drop snapping system, anyone can begin building a model piece by piece. It has never been easier or more entertaining for adults and children alike to build exciting plastic models.

This app also includes ‘Easy’ and ‘Hard’ puzzle modes.
In ‘Hard’ mode, the order in which parts are fitted is important and learning which part must be added first adds a puzzle element to building the many fantastic models, such as sports cars, ships, submarines and planes and many more. The challenge of placing parts in the correct order of construction makes building a model even more rewarding.

Once the model is completed, you can change its colors, play animations and sounds, and watch as parts of the models move and operate. Of course, you can view the model in more detail by panning, zooming and rotating around the the scene to view the model from all angles. Additionally, the parts menu is randomized allowing you to try your hand at the model again and again, and giving the chance to beat hiscores on the in-app global leaderboards.
