Ok this may not actually sound as puzzling to some, but being a newbie to Illustrator and InDesign, it is something which I am hoping an expert can answer. I am trying to create a shape in Illustrator which I can then import into InDesign and use as a picture frame (so I can place photos inside it). The shape is a simple square with the opposite corners being two rounded corners and two right angled square corners (does that make sense?) Now I have easily created this in illustrator by drawing a square with rounded corners, deleting the two opposite corners and replacing them with right angles that I have cut from a conventional square shape. What do I need to do next to create this shape so that it has a simple continuous stroke outline and can be used as a frame in InDesign?
