Hello,
sorry for my english but I'm french.
I'm trying to make a font with inckscape and I'm having a probleme when I do a Union of all my objects, I don't know how to describe it, but all my curves done with "courbe de bézier" ( ) are joined in a line !
I don't understand why.
here are some pic I tooke. the first one is before unioning, the second after

Thancks a lot for your help and reply !

Welcome to InkscapeForum!

I'm not positive about your goals, but it sounds like Union might not the best technique. Since the 2 paths are not connected, or anywhere near each other, and Union needs to make them into a single object, Inkscape has to do some guessing, based on the info provided in the origial paths.

If you need the 2 paths to be subpaths of the same compound path, I'm thinking Path menu > Combine might be the best technique. Nothing will change, except combine the 2 paths into one.

If you try that, and it's still not what you want, would you please describe what you want to do? I can't quite see what's happening with your screenshots. The result of Unioning the 2 objects that are selected in the "before" should not be bigger than the original 2 objects, which is what it looks like in the "after". And I don't understand why objects that appear not to be selected are somehow affected by the Union command. We may need to see the SVG file, but let's go one step at a time.

Let us know if Combine works

Thancks for your reply, and sorry for my latest one.

I thinck I found the solution ! I thinck it's quite the same as your reply.

When I select all the objects I go to > path > change object into path (???) my inckscape is in french but it's the first or second onr both works !
I didn't try to "combine them... I'll try it

But it's solved, in fontforge I can see them and the're perfect !

thanck you !

Oh, I didn't realize that the objects were not already paths. Well, I'm glad you got it working
