Need help in adding knot

Postby nihon94 » Mon Aug 13, 2012 4:38 pm

I drew a circle 10Px(did not use object to path) and duplicate 4 times. Then aligned them and Path/Combined and used Added Knot.
When I started Changed Fixed width I noticed the last circle got space on the right which created problem. Rest of the circles got proper spacing.
I wonder if I am making any mistake and how could I get rid of the right edge space in the fifth circle.
Please refer screen shot.

Thank you

Tried to duplicate yr problem but things worked the way i expected them to. FYI when you combine ellipses they are converted to paths anyway. might you have accidentally opened the ellipse into an arc before combining? Do you have an svg? what system and version are you using?
Your mind is what you think it is.

Thank you for quick reply.
I did not understand what does accidentally opened the ellipse into an arc before combining mean?
I got svg off course. OS: windows vista home premium 32 bit(Japanese).
If this information help you.

I would not group the last one, leave it unto itself/by itself, then all you need to do is convert the object into a path, go into the node mode (you might need to add some nodes first, as most circles only have 4 nodes), then select the 2 nodes that are open, and click on 'join selected nodes', that will close the gap. Now you can group this with the others.

Can you duplicate your results and post the svg? Of the 3 versions of Inkscape I have on hand none can reproduce this problem.

By group do you mean combine? because when I group and wanted to add knot it did not work. Therefore, I had to use combine. I also tried your method of leaving last one and using nodes but did not work well.
Thank you for help.

I wanted to post svg file and read in the forum where I could upload svg file the 2nd link Media fire it says it is Free/Trial therefore, I uploaded file to another server.
This is a download link, (you have to copy and paste link in to your browser(may be) sorry for trouble)
File name and size:Knots 20120813.svg (18 KB)

I opened your svg and took a screenshot without changing anything and this is what it looks like in my development build. No problems, right?

Abunai! Opening it in 48.3 gives me the same problem as you!

- but daijoobu desu!There's an easy fix... Switch to the node tool :tool_node: . as soon as you click on the path you will see the nodes of the original path(before the knot LPE) AND you will also see this little 'control' called the 'switcher'. If it's very small you can try setting the size larger in the path effects dialog (probably won't work)... Just drag the switcher to some other crossing point. it shouldn't be where it is, it's a bug that apparently is already fixed, just not in the current release.

Thank you for detailed reply and Japanese :D . So just imagine, you opened my svg file and it is ok and if I use that I face problem. It means there is some thing with the program. However, I had downloaded version 0.48.2 from the inkscape website.
Anyway, I also used your switcher method. As I clicked the "switcher inkscape showed an error message. By the way what am I suppose to do with the switcher?

After doing various experiments I found out that as flamingolady had mentioned earlier, if I join the nodes then I can eliminate the space. :lol:

Arigatou gozaimasu(thank you)

Thank you flamingolady for your good advice :D . Later I did some experiments and found out, if, I join the nodes I could eliminate the space.

The switcher changes which segment of the 'knot' is drawn on top and which one goes on the bottom by dragging it to the intersection where you want the crossing to change and then clicking it. It should not be on a node, but at an intersection. Don't click it but drag it immediately... clicking is telling inkscape to do something impossible, changing the layering where there is nothing to layer. ...
Using the node-editing method means that all your knot crossings become immediately fixed, if that's OK with you...

Thank you for clarification. I was still playing with knots but sorry I can not proceed with switcher as you have explained because it never do anything except showing error message.

I have also followed your screen shot but nothing. I do not know if I re-install inkscape will it be helpful or not. :idea:

Thank you.

nihon - glad you got the gap closed. I'm sorry, I should have been more specific, I would have used the knot function for the group, then for that last end piece, made an entirely separate circle that I left as a circle, and manually added to the group once it looked like what I wanted. Sometimes I just don't have a lot of luck with editing paths without crashing. It's interesting to see what a switcher is and does, I always learn something here, yay. However, I usually end up finagling nodes manually to get to the end point. good luck.

I appreciate your clarification and help.
Me too learn by errors and mistakes.

Thank you.
