1 curve for 2

[rysujesobie]

Hi,

How can I make one mutual curve for 2 objects? Lets say I have 2 squares, one on top of another. Can they share the same curve, being a border for both of them? When moving it up or down can I change the size of both squares at the same time?

Cheers

rysujesobie, AD doesn't currently allow one object to have 2 different colors, except when using a gradient.  So that is the way I'd attack this.  Make a rectangle as big as with both squares.  Then add a gradient with a sharp transition.  You can use a linear gradient with 4 handles.  2 red and 2 white.  Have the inside handle of each color as close together as possible. Zoom in to position them.  Then to resize you'd move the internal gradient handles up or down.

An easier to control gradient would be to use a conical gradient.  Exports may rasterize the conical gradient so it may not work for your needs.  But to resize all you have to do is drag the center handle up or down.  And the color change is very sharp.

Attached are examples of each. Color boxes.afdesign

If you need two separate rectangles, then I'd make them separate and group them together.  I'd also convert them to curves so I could use the node tool to grab the 4 nodes (bottom 2 of the top shape and the top two of the bottom shape) at the same time then holding the shift they could be drug up and down together vertically to resize.

I hope that helps.

Hello rysujesobie,

If I understood your question correctly, you can enable snapping, attach the two rectangles and group them ("Ctrl/Cmd + G). If you move one side of the resulting shape, both rectangles will change size at the same size.

Hi, rysujesobie,

Yet another way. Different shapes can be nested inside larger shapes as "children." If left unlocked, they will shift size, proportion and position as the parent is transformed.

Or do you mean something more like this? Same basic method applies, but is extended by moving the boundary of the area defining the colors, not a line that has different color assignments on either side.

How can I make one mutual curve for 2 objects?

First, some basics: every vector object must have one or more paths that define its extent. An object's path(s) can be stroked and/or its extent can be filled to make those object properties visible; but even if they are not the object must have at least one path to exist.

For example, an open or closed curve always has one path; certain shapes like Cogs & Donuts may have two closed paths; & "Curves" composite objects created by geometric (boolean) operations like Combine and sometimes Add may have two or more closed paths. Appearances can be deceiving. In this Object examples.afdesign file, there are only 9 filled & stroked vector objects, even though it looks like there are quite a few more.

So what you are asking is equivalent to asking if 2 objects can have one 'mutual' path. The answer is yes, but only for a very limited class of vector object types. Maybe more to the point, an object's extent can have only one fill color or gradient; thus the suggestions for working around that limitation.

Thanks a lot for all your replies. Need some time to process it. Will be in touch.

The answer is no. All nine of your examples feature a single object, anyway.

The answer is no but the solution that will do as rysujesobie wants is...

1. Create 2 squares
2. Create a rectangle that is the size of those 2 squares
3. Now make the squares a child of that rectangle
4. Now adjust the height, width and rotation of the rectangle and the squares will scale with the rectangle.

Yes, there are solutions. My post was in response to R C-R's fallacy to hopefully prevent rysujesobie from being misinformed.

Sometimes, we can all interpret a question differently, I've given an answer that I thought was correct or made sense, came back to the post to read replies and after reading those replies see that I read the question wrong  at that point I go for plausible denial lol!

I was trying to keep things simple for @rysujesobie but consider Compound shapes, for example like below:

To the extent that the "1-(2+3)" compound is an object in its own right, it shares a mutual path with the "1" rectangle.
