How do you change Ref Des for new parts?

Solved!
Go to solution
I have created several parts of different types but they all have the same reference designation letter "U" attached to them. How do I alter the reference designation letters for individual types?

The RefDes prefix (the U) is assigned based on the family where the part is saved in the database. You can change the default RefDes prefix in the Database Manager:

 

1. Click Tools > Database > Database Manager

2. Select the Family tab

3. Browse to and select the Family where you saved the components

4. Change the Default Prefix to the prefix of your choice

Hi guys,

 

I am wondering if I can change the RefDes to the prefix with double letters.  For now, I only can change to a single letter, A-Z and a-z.  Can I change to like SW for switch?

 

thanks,

Yes, just type in the extra letters.

 

Note: I think version 10.0.0 had an issue where this was not possible, and believe it was fixed in 10.0.1.
