May I know why I cut voronoi and the model become like this?thanks ![image](https://canada1.discourse-cdn.com/flex031/uploads/itasca/original/1X/801b2d3e646c204ddec6928098c58cff9906135f.png) ![image](https://canada1.discourse-cdn.com/flex031/uploads/itasca/original/1X/a56f9c6a42613cd7a88630f5db50d2f36800258c.png) [0505-cut vonoroi-25.dat](https://forum.itascainternational.com/uploads/short-url/bqqzG77ZWgcACYKrN6vkBrmAfe5.dat) (194 位元組) [0526.zip](https://forum.itascainternational.com/uploads/short-url/3Asw7jZ8H8sSUKTDGkNIaqu726Z.zip) (776 位元組) ---

See here: [What is the meaning of the wrong?](https://forum.itascainternational.com/t/what-is-the-meaning-of-the-wrong/396) The voronoi only works reliably for convex shapes. You can break your dxf into two convex pieces, or else make one big block and cut it. I also had to decrease the block size to get this to work reliably (12 seemed to work OK). ---

Ok,Thank you so much
