This change in Draft.py will fix the display in TechDraw, but not 3D or Drawing:

hmm several issues at once...
The getSVG function has a techdraw argument that allows to do stuff only for techdraw, but there seem to be several other issues underneath, I'll have a look

Usually arrows are used this way

Did you ever have time to look at this? I noticed this issue but forgot to report it. I use a lot the Arch -> Arch SectionPlane -> Techdraw workflow, but decided to omit arrows, except for dimensions, precisely because of this.

No, it slipped through the cracks. PR submitted. Not sure when it will get merged - as soon as the v0.18 release is sorted, I guess.

Where does the annotation arrow feature comes from? Is this already in master?

Pretty sure that is a Draft Arrow + TD Annotation. Text + leader is coming for v0.19.

Or is this just some macro added to the toolbar?

FreeCAD+GIMP.
I'm not a programmer. I just want to show you how this functionality should look like.
This is a very often used function in mechanical drawings.
