Draw Tool Bar II

Polyline---keyboard command PL (enter)
             There is another thing to be explained. Let me take an example let us say Rectangle. If I give you to draw a rectangle, you can do it in any of the two ways, either you will use Line tool or directly use Rectangle tool. But there is difference too, if you draw using LINE each side of rectangle will behave as different entities, but if you draw using Rectangle tool it will behave as a single object or single entity.The same thing is also with POLYLINE tool. It allows you to draw lines, arcs but when these are drawn in contiguous manner they behave as single entity.
                   
Steps to use this tool:-

  • Specify start point
  • Specify next point or [Arc/ Halfwidth/ Length/ Undo/ Width]
Steps to use the sub-options:-

If 'A',
  • Specify end point of arc
                       HalfWidth                                   Width
If 'H' or 'W',
First let me clear what is Halfwidth and width.
For Halfwidth:
  • Specify starting Halfwidth (A)
  • Specify ending Halfwidth (B)
  • Specify next point
For Width:
  • Specify starting Width (A)
  • Specify ending Width (B)
  • Specify next point
It depends your wish or your requirement or your experience which one to use.
Polygon---keyboard command POL(enter)
                   Here there is nothing to discuss seriously, its all known to you and it means the same as the title. So I will give you the steps :-
Steps to use the tool:-
  • Enter number of sides
  • Specify center of polygon or [Edge] (if you have the centre point then specify it else specify edge                                                                  length)
  • Enter an option [Inscribed in circle / Circumscribed about circle]
