Diedrom

In this post, I want to show you a new application I have seen.
Diedrom is a three-dimensional volume space with pieces.
It is an application that we can use in class to help students in the visualization of pieces and their dihedral projections. According to its author, Santiago Ortiz, it seeks to stimulate the understanding of three-dimensional space through creation and clarify the concept of dihedral projection through experimentation.
It allows us to create our own figures, change the colors, obtain the views, rotate the pieces...

Here, I let you the link to use Diedrom, it is free and you don't have to pay for use it.
