Line to image in perspective

I’m building an application in perspective, for simplicty I have chosen to use a coordinate view.
In that view there will be an image in the center, its a drawing of the machine used.
On the sides i want to show data regarding the sensors that are in the image.

I want lines from the boxes of information to the different parts to the cards with information.

But how do i make the lines easy? Maybe I’m missing something

Version? 8.3 has drawing tools. In 8.1, create an SVG in inkScape etc and import it

8.3 so i tested the drawing tool and while it works it is isn’t completely practical for the job. I cant see the line on an overlay while i make it. But I guess it has to be good enough.

An alternate to using SVGs in 8.1 was to use the “pipe tool”. You could give that a go in 8.3
