MeshMagic 3D Modeling Software can help you create 3D models. You can create models from scratch or import them, even if they have been created with other tools. In this regard, it is good to know that various formats are supported, including 3DP, 3DS, 3MF, OBJ, PLY and STL.
The program’s interface makes it much easier to use than other similar tools. So, if you have some experience, you will probably start to use it without even consulting the online help documentation. Most of the working space is occupied by a large perspective view and three smaller ones corresponding to each of the three axes. The tool allows you to create simple geometrical objects, like cubes, spheres, icosahedrons, and toruses, which you can modify by altering their dimensions, position and rotation degree. You can generate 3D objects from 2D outlines. Luckily, the program supports extruding surfaces from any object. Although it is possible to colorize objects, it seems the program does not allow using surface textures. Likewise, unlike other tools, it does not support any kind of animation.
To sum up, MeshMagic 3D Modeling Software may be not as sophisticated as other similar programs. Even its developers claim that it is available for free with the hope that users are encouraged to try their Image and Design Software. However, it is enough to create simple sketches and visualize existing models. If you intend to start a complex project of this type, though; you had better keep on looking. I know at least one very advanced program available for free.
