I am working with the latest version of Adobe Illustrator. I have the following:

two rounded rectangles

I would like to cup the shape at the following location, so that I create a flat document icon that is folded in one corner:

slice line of rounded rectangle

How I can achieve this? The knife tool doesn't do straight lines! Even though I press Ctrl / Shift / Alt .. etc

Any help would be greatly appreciated.

Thank You.

I usually create a shape and use pathfinder panel to cut out some part. –  Vnovak Jun 26 at 10:45
    
Knowing what I'm trying to achieve, can you please walk me through what shape .. etc you'd create? And how you'd cut them using pathfinder panel? –  Ciwan Jun 26 at 10:50
    
Take the pen/line tool and draw that line. Then in pathfinder use divide and delete the other part –  joojaa Jun 26 at 11:06

First of all, I worked in Outline mode (Ctrl+Y).

  1. You have you shapes stacked. enter image description here

  2. Turn on Smart Guides (Ctrl+U) it will help to fit exactly into intersection points. Do a straight line of cut with Pen tool (P). enter image description here

  3. Do and complete any shape which will enclose your smaller rectangle enter image description here

  4. Select all shapes, open Pathfinder panel and use Trim. enter image description here

  5. Select unnecessary shapes with Direct Select (A), you can select even part of path or one point. And press Delete. At first press you will delete exactly what selected. After delete the whole path will be selected - press Delete second time. enter image description here

  6. Back to Normal mode (Ctrl+Y).

Brill! Thank you :) –  Ciwan Jun 26 at 12:22

Click TRIM or MERGE in the pathfinder, then use the Direct selection tool and delete all unneeded anchor points! enter image description here

Better not to keep opened paths. –  Vnovak Jun 26 at 11:25
    
@Vnovak Better in what way? –  Komental Jun 26 at 11:26
    
Opened path can be a cause of error (e.g. with some RIPs) –  Vnovak Jun 26 at 11:28
    
@Vnovak OK. Mathematically the fill is calculated as if it is closed. I have never seen problems with that. You can easily close the path by Ctrl+J but I think it's just an extra unnecessary step in this case. :) –  Komental Jun 26 at 11:32
    
Mathematically, stray points also must not raise errors :) –  Vnovak Jun 26 at 11:35
