Hi guys

I saw a vid a little while ago that showed me how to easily round one corner of a rectangle and I can't remember how to do it.  Im sure its very simple - could someone enlighten me please??

    I'm a noob to illustrator, so maybe don't understand the question, but I was able to create a rectangle with 1 rounded corner by doing:

    1. Create a rounded rectangle

    2. Add a non-rounded rectangle over one half, so that it covers two of the corners

    3. Add a non-rounded rectangle to cover the other corner I want square

    4. Select all 3 shapes

    5. Use the pathfinder> Unite

    Looks like a rectangle with a rounded corner to me.  This was using AI CS6, I'm not sure if the same thing would be possible in older versions.

    This is easily accomplished in Photoshop CC using the rounded rectangle tool. Go to properties, unlink the corners and give 3 corners a radius of 0px while using the desired radius on your rounded corner.

    Seems backwards, but you can save it as an .eps and open it in Illustrator... takes a few seconds.

    i always find it funny when someone's answer to how to do something in illustrator is 'use another program'

    I found a simpler way:

    1. Create a square or triangle

    2. Create a circle with the radious you want your corner to be

    3. Copy Circle (if you want more than one corner rounded)

    4. Place Circle over the square to create the radious you want on square corner

    5. Select Circle and sqaure - make sure circle is on top

    6. Click Divide

    7. Ungroup it all

    8. Delete unessessary parts

    9. Select all pieces again

    10. Click Unite....Done

    Strange enough, InDesign has it all! Do what ever you want in ID copy and paste into AI

    The easiest way for me is to create the rectangle w/one rounded corner in InDesign and save it as an eps then open it in Illustrator. I don't know why Adobe can't make this InDesign feature work in Illustrator too. Maybe next version?

    Illustrator bezier support is complete junk. Sure it's an awesome piece of software for logo design and small print jobs and web pieces but just don't call it an illustrator.

    If you are into complex vectoring either get plugins like Vectorscribe or XtremePath or just switch to new CorelDRAW X6 or Autodesk Sketchbook 2013. You will be amazed by polygonal control of both, heck X6 even offers vector 3D cast shadow of single two point line if you desire so with one click and drag.

    That is very interseing one probably could make a sort of template with a rectangle with one round corner one with two and one with three and each could have a round corner radius adjust able independently.

    I wonder if they could code that as a tool?

    Very interesting and clever.

    We've had many approaches in the past, including graphic styles, actions and scripts.

    All of them suffered from specific limitations. None of them may be called "beautiful". All of them are just that: Mediocre workarounds.

    Although not that old-fogyish as Illustrator, FreeHand and some other programmes are antiquated as well in that area. To me, a true "Smart geometric primitive" would not just offer a couple of predefined corner styles. No, it would allow you to define your own corner styles, comparable to the way you can create corner tiles inside pattern brushes.

    That would be an innovation. Just doing it the same way as FreeHand or Draw does at the moment would be a reactionary step.

    Well to me it does not seem to difficult to accomplish even if there is no tool for it.

    Sure, drawing an arbitrary single-cornered, horizontally-aligned rectangle from scratch isn't so time-consuming. But see how long it takes you to add two corners each (different radii) to three existing rectangles which are all at odd angles. Doing it manually becomes less viable rather rapidly.

    Is that what the OP asked?

    As far as d4efending the indefensible I who and where the poster sees this hapening in this tthread? Or what it has to do with this thread at all?

    the procedure includes

    multiple fills

    round the corner of the 1 fill

    the 2 - apply transform effect using the scale or move options so you mask out the rounded corners (making visible just the ones you want)

    and depends of the corner you want you use fils and move them over the object

    this is a live effect which is the beauty

    It's beyond belief that such a simple task can't be done in illustrator in 2012. Just saying.

    Smart geometric primitives, Adobe. Take a look at your other drawing program. But no rush; you're only decades late on this.

    The itbros script looks good, but you'll need to know the exact corner radius you want—or, run the script multiple times as you sort it out.

    I have two different tools in my Ai arsenal.

    I bought VectorScribe, and it's awesome. It offers a lot more than just rounding single corners.

    www.astutegraphics.com

    And my other corner rounding solution is developed by CValley Inc called "Xtream Path." It is also very cool!
