Midpoint of an Existing Straight Line or Arc

Example

1. NEW STRA

2. FPT MIDPOINT OF @

3. TPT MIDPOINT OF @

   (or NEW STRA DEF MIDPOINT OF @ MIDPOINT OF @)

   The line takes its endpoints as the midpoints of the two hit items. If the two hit items were an arc and another straight line then the situation can be as indicated.

   

   The required midpoint can also be that of one side of a closed polyline primitive, for example, a rectangle. Line definitions of other elements (for example, a line that comprises a piece of a design item in a VIEW) can be extracted by cursor. As well as using a cursor hit, the STRA or ARC can be identified explicitly.

   Note:
   Note that with this variation of the MIDPOINT syntax, the presence of the OF keyword is mandatory.
