Hello 

I have an svg file with several identical shapes scattered on the page.
I need to draw lines/othere shapes inside one shape and get it dinamically copied to the other ones. Is it possible to achieve in InkScape? Any guidance is welcome.

Thanks and have a great day!

There is a clone option.
Delete unused ones and then add in new cloned items.  That way you can always updated same objects all at once.

Danjr, Tyler thanks a lot for your answers!

The clone option is definitely interesting, however it doesn't seem to help in this particular case.

I have a net of equal shapes and I want to draw the decoration inside one shape and make it dinamically copied to the rest ones,
so I can see the whole net using the same design. The clones seem to only share the outside shape. When I draw something inside the original shape, it is not copied to the clones.

Am I missing something here?
Thanks much

Two approaches I'd consider.

The parent path of the cloned paths can be edited, including adding new subpaths.

Groups can also be cloned, so that after tiling/cloning the group, the parent group can be edited to add more objects into the group.
