This software is good for building parts that are dimensionally accurate. This software is useful for people who want objects to fit into each other or to design prototypes.
This software allows users to take photos of a model with their smart phone or camera and then it will create a 3D model using the photos that were taken.
This software made by google, good for beginners to the 3D modelling world, It is full of libraries and tutorials to help develop the users skills. But make sure to check the file before exporting as an STL as the mesh modeller may not automatically stich the walls together creating a solid model required for 3D printing.
