The command Extract Solid from Surface has a bug when you enter a value with a decimal value, where it doesn't accept either a comma sign (,) or a period sign (.) before the decimal value. 

The workaround is to type the value you require in Notepad and then copy that text and paste it into the Extract Solid from Surface dialog box. Note that you can't use Ctrl+P to paste, you need to right-click in the box to Paste the value.
