“Combine” will ignore all the selected objects’ curve properties and combine those objects into a new curve combination with new curve properties. Same as other objects, this new combination can be selected, copied, pasted and set properties.
“Uncombine” will get the combination back to the curve objects separately. The objects after “Uncombine” may be different from those before “Combine”. “Undo” should be used to restore the original objects.
The shortcut keys of “Combine” and “Uncombine” respectively are: Ctrl+L and Ctrl+K.
When selected the “Group” function will keep the selected objects’ original properties and make them into a new object, and this new group, as the same as other object, can be selected, copied, pasted and set object properties.
“Ungroup” will turn the object which has just been grouped into previous situation. The object which has just been grouped by more than 1000 objects will become 10 objects. If the object is a vector file which has different pen color, it will become some objects according to color.
The shortcut keys of “Group” and “UnGroup” respectively are: Ctrl+G and Ctrl+U.
