I have just started to use Dia for designing ER diagrams and I cannot seem to find a way to show total participation, which is usually expressed by a double line. Thank you.

Just double click on the line you want to represent double participation and switch Total to Yes:

However, note that the line must have been created using the Participation symbol of the ER sheet.

You can add new shapes to the software, but you to create them first.. I've just done an example for you (it's in Spanish but I think you'll understand):

  1. Create the new shape in dia

enter image description here

  1. Export to a shape format

enter image description here

  1. Select File → Sheets and Objects from the menu to open the Sheets and Objects dialog or press F9.

enter image description here

  1. Sheets and Objects dialog. Click on the New button - a new dialog will be opened

enter image description here

  1. Select your new shape and then click on Acept

enter image description here enter image description here

  1. You'll see your new shape like this:

  1. Add it wherever you want

You can check this manual.

Hope you find this useful!
