Hello everybody, ı would like to ask a quick question.

Is there any way to make it my imported pdf file a little bit transparency so that ı can see my wındows in a wall ?

Thank you so much.

Yours..

Why aren't you seeing the windows in the first place?  Can you see them in the Revit View you are printing?  

...Raster -- not Vector.

I think there is a misunderstanding. I upload a PDF file so that I can model it on revit by using it as a referance file but When I draw a wall the first the I can not see the window anymore. I think it is now more clear.

Select the PDF and change Draw Layer to Background from properties.

Ah, I see.   So, you are tracing the PDF in Revit?  Does changing Revit's Background color help?
