Interesting application in which we can pass the ideas we have in mind in a 3d sketch for greater facilitation, thus being able to be shown to others arriving to have a better understanding of what you are talking about, so that then perhaps they give their opinion and you can improve on the concept you're developing. Simply something functional and with good results.

What should be seen is the difficulty of its use, it is the only defect I see, how long it takes to learn how it works fully.
