TinkerCAD is free software which you can access on your web browser without the need of downloading it. It is user friendly and easy for beginners to use with built in lessons and tools.
TinkerCAD makes it easy to create basic models such as furniture, key chains, houses etc. The models are designed by selecting dragging and placing the basic shapes and then joining and modifying them to create the models of your wish. The customised shape script lets you use the software in a more flexible way. The public designs can be views by others and they can modify them.
TinkerCAD is above all when it comes to using basic and simple features, combining aligning and arranging of objects. It is easy to modify the already built designs using tinker cad .The 3D stl models can be imported for modification into other models or 2D SVG images can be imported to make expressive patterns.
