Hi,

I have sketched a dodecahedron and now i want to make it a closed solid body (see the screenshot).  
Does anyone have any recommendations how to do it?

Thanks

If the pentagons work as planes, make a bigger cube and use the split body tool to remove the unnecessary parts.

This guy is a GEM! He gives you the math and moves. Just translate them to “New bodies” that you can subtract instead of using “curves”. [https://youtu.be/CX-SxShqjaQ?si=H8Km-jXjgekWnhH2](https://youtu.be/CX-SxShqjaQ?si=H8Km-jXjgekWnhH2)

Really awesome math skills, it is just a little bit difficult to follow the instructions in Shapr. Thanks mate!

It worked very well! It took me some time to figure out i need to add planes 😃 , but works great!

Yes, all steps must be repeated for each side. But, if you have a plane of symmetry, then only half of it 🕶

There are two ways to create dividing planes:  
-offset planes  
-by 3 point

Yes, of course there are several tools for creating the planes, but I meant it for this case… Another interesting question is how history could speed up this process, since there is only a body grid at the beginning of the process.
