drag-drop a circle... why is there another one under it?

Postby barny18 » Sat Dec 24, 2016 8:11 pm

Hi
I have reciently loaded Inkscape to modify a relay schematic and pcb layout for use in Fritzing.
I am figuring some things out but I have a problem repositioning the existing circles on the PCB layout, when I select one circle and reposition it, a second identical circle remains in the original position.
I have tried bringing the second (stationary) circle to the front but that didn’t have any effect.
Why are there 2 circles, if they are intended to represent both sides of a pcb then is it possible to link them so they both move in unison?
Any input that might help a beginner out is welcome.

Regards

PCB - printed circuit board? Fritzing is open source CAD software?

I have no idea why there might be 2 circles on top of each other. Did you perhaps duplicate the circle?

Or is this a pre-existing file which you didn't personally create? Where did the file come from? Can you share the file?

They might be in two different groups or layers, that could be the reason why you cannot change their stacking order. Or the bottom one could be locked (either by locking the layer or the object), which would mean that you can't even select it.

To move them together, make sure they're both unlocked, then drag a selection box around them (hold down Shift to only select things inside the box, and not the object where you start dragging), and then move them. If you can't move them easily, try holding down Alt while moving. You can also group them, but then any layer structure that may be important will be messed up.

Hi
Thanks for the replies;

Brynn,
Yes I am having my first go at making a printed circuit board in Fritzing. I wanted to include some relays but the Fritzing library doesn’t have the correct relay layout. I found one I could modify and was told I could modify the design in an editor like Inkscape.
So in another first for me I loaded Inkscape and pretty quickly ran into problems :? .
The file I am trying to alter is at https://github.com/Eunanibus/Fritzing-Parts specifically the file 941-2H-5C_PCB.svg .
At first glance it looks simple but the second images are a problem, when I try to resize the footprint and/or reposition the images they don’t move.
I am also communicating with Fritzing about how the PCB layout should be designed but with respect to Inkscape I would like to understand the file I am working with and (hopefully) if possible be able to move and copy both images as one piece.

Moini,
I am still finding my feet in Inkscape, so far I have been unable to influence the position of the second (lower) images. Even resizing the footprint (the box around the 8 circles) only moves the top circles maintaining their position inside the box/frame while the hidden circles don’t move and end up sticking out of the frame.
I can’t make the select box and shift key process work, the ALT key only works for the top image... However, all is not lost; I now know that dragging a selection box around an image is a simple way to select a specific image :-)

Regards.

yes there are 2 layers named "copper1" and "copper2". (use shift ctrl L to show layers)
the easiest way to design imho would be to remove layer (copper2) place the circles in one layer (copper1) then duplicate this layer as copper2 then draw the schematics peculiar to one side.

Structure is this:

Code: Select all

root, contains:
-> gray frame
-> layer "Copper 1"
    --> Group
       ---> circle
       ---> circle
       ---> circle
       ---> ...
       ...
-> layer "Copper 2" (same contents as Copper 1, as far as I can see)
    --> Group
       ---> circle
       ---> circle
       ---> circle
       ---> ...
       ...


Ungrouping: Ctrl+U
Entering a group for editing without ungrouping: double-click on it, or press Ctrl+Enter, then you can select individual items
Select under: Alt + click

If you follow V1nce's suggestion and remove the layer "Copper 2", be mindful of the labels. I think the circle's names might actually be important - but I don't know. This is something you'd need to find out yourself first, with the help of the Fritzing community, before you delete something that has a name, and then replace it by something that has an auto-generated name.
