I just started learning Alpha and one thing (among many) is doing my head in - i cant seem to find the function to draw/enter data in relative coords.
Looked at manuals, watched videos/tutorials - everybody starts to draw examples at 0,0 ABS, which is all good and well.
But what do i do if i want to draw a, say, rectangle from random picked point and is 20x10 size ? I dont know the coords of first picked point.
Disregard all the snapping functions for now, how do i enter data RELATIVE to start point ?

Do i make sense ?

I come from autocad, which i use for decades by now(started on R10 on dos ), and all i might need to do there to switch to relative is to just add @ to entered data string (i draw/modify almost completely in CLI). For the life of me i cannot figure out how to do this in Alphacam... Embarrasing.

Also, when it comes to snapping is there a reference snapping in Alpha ? Assumed extension lines from indicated snap points or something similar to autocad ?

In Alphacam, you do not need to type an @ symbol to specify relative coordinates. Instead, simply enter the offset from your starting point (e.g., 20,10).

That is exactly the problem, if i enter 20,10 the end point ends up at 20,10 ABS, not REL to start point.
