I am a bit rusty on drawing but spent years using Generic Cadd and then Visual Cadd. I recently began using TC 17 Deluxe and am starting to get used to it. However, I am having difficulty figuring out how to track from a specific location (ie, the end of a line, the center of a circle, the midpoint of a line, etc) a given distance (and perhaps changing the direction again) to select the starting point of my next action (line, circle, whatever).
For example, let's say I have an inside corner that I want to use as my reference and I want to place the center of a circle @ x= +5, y= -6.875 from that corner. How do I do it? The quick command in Visual (and Generic) Cadd was 'tk' (short for track); you selected the command you wanted to insert (line, circle, etc), typed 'tk', snapped to the point from which you wanted to reference- this put you in the 'tracking mode', moved the mouse in the first direction, input the distance, moved the mouse in the second direction (if you were tracking in more than one direction), input that dimension, hit the escape key and 'click' to place the starting point of the new entity. The starting point of your new entity would now be exactly where you wanted it.
I assume that TurboCadd has a similar ability for 2D drawing, but I can't figure it out! Can anyone help me with this? Thank you!
