Illustrator is a great tool for creating graphics, but sometimes you may find that you can’t erase something that you’ve created. There are a few reasons why this might happen, and fortunately there are ways to fix it. One reason why you might not be able to erase something in Illustrator is because the object is locked. Locked objects can’t be erased, but they can be edited or copied and pasted elsewhere in the document. To unlock an object, select it and choose Edit > Unlock Object. Another reason why you might not be able to erase something is because the object is protected by a layer mask. A layer mask is a graphic that shows which parts of an image should be visible and which parts should remain hidden. To remove the layer mask, first make sure that the object isn’t protected by another layer mask or locked, then choose Edit > Clear Layer Mask. ..
