3. Modelling software overview

One of the main advantages over the programs listed above is the ability to work online. This is an Autodesk software package that can offer many additional tools with a license. However, for small projects, the tools offered by manufacturers in the free online version are fully sufficient.

The program is especially suitable for children because all the tools are visible and clearly understood. This online version has advantages. The teacher can create classes and teach for the whole class. Projects can also be done in teams by "inviting" another user to the project. Another very handy tool is comments. They can be both written and hidden. The program allows you to import already created *.STL files and edit them. There may be problems editing individual blocks in the model because such blocks are "locked" by grouped parts. 

Which program to choose for modelling, depends primarily on the goal and the user’s skills.
