Transparency 2d symbol

[weronika28]

I am trying to change a 2d symbol of an object. I added a transparent shape and put it above a table. Unfortunatelly it is only showing up in the tab where I change the symbol. When I load this symbol to the project, it stops being visible. How can I make this transparency visible in the project?

Could you just do without the Fill? When you say "load into the project" is that the same project in which you made the modification or a different one? Did you override the previous object? If it is a different project, have you reloaded your libraries, given that you did not just save to the embedded library previously?
