Thanks for your input

As mod answers go, maybe this could use a little more constructive direction. Others, who may have the same question look to whomever is responding for answers, not reiterating what is already apparent. The correct way, I believe to modify the numbers in polar tracking is to
1. right click on the icon
2. select “Settings”
3. check the box Additional angles
4. click “New”
5. Enter angles you wish to add to the default increment.
so for example if u have it set to 90º, and add 40º.
that will insert one extra angle to the list that it snaps to 0,40,90,180,270,360.

When it comes to drawing a line at an angle, there are several ways to accomplish this…

Using polar coordinates which consist of a starting point, a distance and direction specified locally as @distance<angle

i.e. starting at point 0,0 with a distance of 10units at an angle of 45 degrees would be input thusly: Line

enter first point: 0,0

next point:@10<45

etc.

Another way to do it is create the line then rotate it

so from the command prompt or selected from the tool pallet, Line
specify a starting point and end point
key in the rotate command
then select the object, key enter
then enter the vertex you want to rotate from
and enter the angle in reference to the current line.

These are by no means complete instructions, but they at least offer direction that might help some users.

means, you are doing something wrong!
