How do you package files so that others can use them

Hi hankwen,

The inquiry you posted is a little bit ambiguous. It would be helpful if you can add more details.

Based on what I am able to pick up, what you want is to share your circuit file (*.asc) which contains your model (of a particular device) with its symbol file (*.asy) with someone else.
I am guessing that you can be helped by watching this tutorial video.

For best portability store/copy all user models in project folder. All that you need - zip project folder and send to others.

Hi John 

I have to creat the new symbol use the .lib file,and change to the attribute by the““Edit”→“Attribute”→“Edit Attribute” .But I download cases of other companies with the circuit file(*.asc),It can be used directly without any change。

Open Autogenerated symbol, Save as in Project folder.

Open symbol from project folder, delete ModelFile attribute value, save symbol.

Place LIB file in project folder.
