Copying shape from master sketch fails on curves

[jze]

Hello,

when I follow https://www.youtube.com/watch?v=2Yee1pSqTLg to make another sketch linked to master sketch (to be able to extrude different parts of the sketch with different size), I select all the points from master sketch and then I draw the same shape in the "slave" sketch. When I have the entire shape drawn I hide the master sketch but only part of the shape in the "slave" sketch is shown although I can see (zoomed in), that there ARE all points connected (in the attached picture the green sketch is the master one and the white is the recognized part of the "slave" sketch).

Is it a bug or am I doing something wrong?

You do something wrong, but without the file we don't know what. A wild guess: You made parts of the sketch as construction geometry shown in blue.

I don't understand why he selects vertex.
Lines are easier to catch and gives less external objects selected (better to repair after tnp).

For such use cases it is worth to consider Sketcher CarbonCopy.

No, I did not.

I did not save the previous attempt so I recreated it again. Although I am not aware of doing anything differently,
this time it looks different, but I wasn't able to create a pad from the copy anyway as it threw an error (vzpěra2a.FCStd).

Because the video explicitly stated not to. After selecting all lines/curves (turned red) what would I do?

I tried (see attached file vzpěra2.FCStd) but when I tried to create a pad it threw an error.

I tried

There is no CarbonCopy in Sketch. It is empty and thus cannot be padded.
Furthermore you have garbled the model with an additional free floating XY_Plane001 .

??? When I doubleclick any of the sketches I can see the shape (in Sketch001 with constraints, in Sketch just the shape).
The XY_Plane001 was added automatically.

Edit "Sketch". The solver message says "Empty Sketch". The list of elements is empty and so is, of course, the list of constraints. Editing a sketch doesn't automatically create a CarbonCopy. Believe me, it is empty.
What you see when editing "Sketch" is indeed Sketch001. Test the following: make Sketch001 invisible and edit Sketch again.

The XY_Plane001 was added automatically.

Not really. If you create a sketch outside of a body it is created without such a plane. You probably copied it from inside of a body with dependencies included.
