Can't switch to edit mode

Hello guys! Why is it that when I reopen my file, I can no longer switch to edit mode? Thanks in advance.

Need more info. Do you have your model selected? Is your mouse pointer in the same window as the model when you hit tab? Could be a number of reasons.

Hit the tilde key (~) to show all layers and make sure that (in object mode) the object you want in edit mode is a) the only one selected b) the last one selected (active).

Got it! Thanks a lot guys! :smiley:
