I created an assembly from a part and got a message about .asmb templates when saving it. I saved it anyway (as a assembly) and then when I returned to this assembly from another assembly a part was missing. This part then wasn't saved on my computer as a part. I decided to start a new assembly some time later and the part appeared before I could add any components. Now every time I make a assembly it starts out with that same part. I am very inexperienced and just want this problem to go away. Additionally, I have tried restarting solidworks and turning off my computer. Does anyone have a solution to this problem?
