Beginners' Questions Knot effect looks all wrong

    Knot effect looks all wrong is there a sequence that has to adhered to? I used the following work flow and got the result shown in the attached file

    1. Created two circles then centralised them
    2. Created group then object to path created duplicate and pasted then moved the two objects until they were overlapping
    3. Created group then object to path
    4. applied path knot effect and got the attached file. I had anticipated that the line breaks would be where there was an intersection

    Hi.

    What is step 3 for when it´s already paths in step 2.

    There seems an issue as all circles have the same path direction.

    Try the following:

    1. draw a circle - Object to path

    2. duplicate - scale  ->Path->reverse

    3. select both and Path->Combine

    4. Duplicate - move in position

    5. select the 2 and group

    6. call for Path effect->Knots - adjust Gap length:

    Hi PP

    thanks for the reply. I have followed the sequence and can duplicate the pattern you describe but it’s still not the fact I am trying to achieve. I am trying to creat the overlap as if the two sets of circles were solid bangles and they were interwoven like Celtic knots any suggestions.

    Your help is appreciated and sorry if these questions are a bit inane.

    I'm struggling to get the desired result with two circles as the starting point - I'm not sure why. But for this specific case, starting with two squares and rounding their corners completely to make circles seems to do the job.

    1. Draw a square with the line thickness you want. Round the corners all the way using the handle in the corner.
    2. Duplicate and position where you want it.
    3. Select both then Path > Combine.
    4. Add the knot LPE.

    But note that the result probably won't be quite what you want, due to the line caps. Using rounded caps gives the best visual appearance. But assuming you want a hard cut-off you'll find that the square and butt caps cut the overlapping lines off too squarely, rather than following the shape of the line that's being crossed. The only way to get a better result would be to construct the shape manually, rather than using the LPE.

    The Knot LPE won´t work on this set up. It´s needs simple path and the crossings look best when in an right angle.

    The workflow is as here:

    When you have something like this in mind:

    you need to establish new nodes for one outlined+color-filled circle at the crossing - open it via Break Path at selected nodes and add a new segment on each outline and reshape the curvature:
