Nodes - modifying equally

Postby Janne » Thu Oct 30, 2014 9:49 am

I have been searching for an answer to this problem ( and learned a lot new stuff :) )

Is there a way to apply exactly the same modification to every node in f. i. this figure?

Otherwise I have to count the amounts of clicks with > on every node:)

Inkscape is GREAT :)

For the above example, here are some hints:

Using tile clones, you can make a repeated pattern in a circle. Any modifications to the original segment will be replicated for the other segments.

Refer to Tile Clones, Tricks in the manual. Also see the manual section on guides, and the release notes on the latest version (pre .91) for improvements on guides.

Have a nice day.

I'm using Inkscape 0.92.2 (5c3e80d, 2017-08-06), 64 bit win8.1

The Inkscape manual has lots of helpful info! http://tavmjong.free.fr/INKSCAPE/MANUAL/html/

Thank you very much :)
I am not sure that I understand what you refer to but I'll practise. I am new to Inkscape but I love it so far. Some tools work much better that Illustrator's tools :)
Have a nice evening.

Oops, td sneaked in a message while I'm typing :roll: . Now that's a really fancy way to approach that kind of image! These below may be a little easier, for a newbie.

There are a few ways to move nodes by precise distance. It depends on your image and your needs, and eventually, you'll acquire a preference for which technique to use. The flower shape in your screenshot is probably as complicated as it gets, for example, if you want each node to be moved outward radially by the same distance. But while complicated, not so hard to do. I'll start with some easy scenarios.

If the nodes need to be moved vertically or horizontally, there are a couple of ways. With the Node tool engaged, there are 2 spinboxes in the control bar, labelled X and Y, which allow you to move the nodes to precise x and y coordinates. Just a little simple math to calculate the values. 2nd way is to use grid or guides and snapping. or depending on your drawing, there may be other objects, or various snap targets which can be used. Snapping: http://tavmjong.free.fr/INKSCAPE/MANUAL ... pping.html

Well, you can use the X and Y coordinates to precisely place nodes, even if they aren't being moved horizontally or vertically. It's just that it's much harder to calculate where to put them. Here's the manual info, for more details: http://tavmjong.free.fr/INKSCAPE/MANUAL ... ition.html

Here's how to move the nodes at the tips of the flower petals, in your screenie, outward, radially.

-- Select only those nodes that you need to move
-- On the Node tool control bar, click the "Show Transformation Handles" button (3rd from the right). You should see the same arrow handles as you see with the Selection tool. It manipulates the nodes in the same way as the Selection tool manipulates objects.
-- To keep things in the same proportions, and to move the nodes from the center, hold Ctrl key and Shift key, grab one of the corner arrows with the mouse, and drag outward/inward.
-- Just for another neat trick, click on one of the highlighted nodes. Notice how the arrow handles change, just like with the Selection tool.
-- Grab one of the corner nodes and drag. This will rotate the selected nodes. Pretty cool effect on radially symmetrical objects (which I draw a lot of)!
-- While the handles are enabled, you can also press the "h" key once, to flip the selected nodes horizontally. Likewise, the "v" key flips vertically. Probably not very useful in this drawing, but might as well mention it ;)

I hope some of that is helpful :D

Thank you very much, Brynn!
I saved your links and will check them out tomorrow :)
Your instructions have to be followed with attention and it's too late for me this evening.
Have a nice evening :)

I am sure that I'll play around with these new - to me - tools. Thank you very much both of you!

The clone option might be the one to go for in this case. :)

Here's a better example:

Thank you, Tylerdurden - clones, tiles and grids are the way to go :)
