Thank you all for your patience

What I wanted to do is to draw straight lines between to point by plotting a point and drag a line to anotherpoint I am usualy using cad system as TurboCad
The UI of InkScape is new to me and not so easy to understand (my opinion)

Hello
Inkscape appears to me to be very slow and very complicate to use
I can believe that it must be possible to draw simple lines with InkScape

Unfortunately no option in the interface seems to allow to do that ?

I need an Inscape user interface specialist to help
