Etrack problem

Hi.

I use to work on autocad. On autocad, I Can stand my mouse on a point, without select it, then go on the right with esnap and write "10" then the first point of my line is 10mm away from the first selected point.

But when i do the same in draftsight, the software start from my last point, and not from the point that I show to my mouse.

So i Can not strat to draw my windows 1 meter from my door for exemple.

Can you help me?

Of course a Can draw a temporary Line instead but i'm looking to fond the good way to do it.

Sorry for my english but it's not m'y language.

Thank you
