Help with transparency

[wizard509]

Whatever your background color is, is what is going to show more and more the more transparent your object is.
So make or clone your shape and set it to no transparency, and flat fill. Make it whatever color you like and put to back.
Now when you want to change the background color of your object just select that background shape and you will be easily able to change the object background color. To select this shape hold ALT and click on the shape until you get the one you want.
OR easier:
If you just want to change the whole background page color (your drawing page) and not create another shape you need to hold the control key and drag your color onto the white page color, this will in affect change what was the white "gradient" to what ever color you changed the page color to, so now when you export your object no more white, only the color you changed the page to. This is a very long explanation of a very simple process. Easy peesy.
I'm a little gun shy of posting things like this for fear of making something more complicated than it needs to be. Anyway I hope this helps.
