I want to sweep a square along a simple figure. The square is on

I then realized that I needed to close the small circle a bit more (it is supposed to be a hook) so I went from 180° to around 220° and this resulted in sharp endings (the plane was not normal to the line anymore). To fix this I need to set

I must understand "normal" wrong, for me this means "perpendicular" - so a plane that is perpendicular to the end of a line. What I get is a plan which is

What am I doing wrong?

*Plane 2*and initially the smaller half-circle in*Sketch 1*was at 180° so I chose a "Point Plane" category for the plane. Worked great.I then realized that I needed to close the small circle a bit more (it is supposed to be a hook) so I went from 180° to around 220° and this resulted in sharp endings (the plane was not normal to the line anymore).

*Plane 2*so that it is normal to the edge of the line of the smaller arc, to which I used "Point Normal".**This is what the document above is supposed to show**.I must understand "normal" wrong, for me this means "perpendicular" - so a plane that is perpendicular to the end of a line.

**parallel**to the line 🤨. (and of course the whole sweep fails)What am I doing wrong?
