straight start from a specific point

[New Rider]

Good morning to all, surely it will be a cabbage but unfortunately I do not go out.
In essence I have drawn a straight line we say having a length of 50 units.
I have to start a second orthogonal straight/colline to this at about 10 units from the final point of the previous tracked line. In the default settings of dynamic insertion I have the reference from the origin of the design. I would need the dynamic insertion to report the original quotas of the point they select (both the final/initial/mezzeria etc).
In the example below I should start a line 500 mm from the yellow initial point for so long I should place myself on the starting point type 500 and from there start with the starting point of a new straight.
I hope to be explained ..

Thank you.

line specific first point: da (from in English) - selections reference point (yellow)<offset>:</offset> @500>0 (the angle depends on how units and angles are set)and the line departs 500 after the yellow circle

Hello crystal, I tried but it didn't seem so complicated to do it. once I saw from a colleague of mine that the insertion was automatic. i.e. it was enough to select the desired point and through the tab key (I think they went to insert the distances from the selected point) ..probably wrong something. .

What you've seen doing to your partner is called "temporary quitting", you find it in the online help of autocad.
Temporary tipalternatively, pull the first line and continue without ever leaving the command, when you are finished delete the lines that are not necessary.
