When saving objects from weldment, you may encounter a message about this, that objects contain illegal names. Mainly it concerns the sign /, which occurs in operations Trim / Extend and less commonly used Move/Copy.
The general rule is this, that object names come from the last operation on the object. So you can also change the names directly in the operation tree. Nazwy z niedozwolonymi znakami można zmieniać podczas zapisywania obiektów – jednak każdemu ręcznie.
I guess, that you will use the magic button Automatically assign names, who will do it for you!
