  TAPE command.

6.4.  THE DISTANCE COMMAND  on the RESIZE pop-down menu allows you to SELECT  two points in a drawing and have the computer tell you, in the "command prompt area" at the bottom of the screen, what the DISTANCE is between those two points.  (The computer  will also be giving you a lot of other information about the location of the two points, but the distance is the first numbers in the list.)  For very accurate measurement use the SNAPTO sub-commands when you SELECT the points.

6.5.  THE MEASURE COMMAND on the RESIZE pop-down menu allows you to mark any line object (LINE, ARC, CIRCLE, POLYLINE) into segments of a specified length.  The line is not broken into the segments.  The purpose is to create point entities that can  be used as points to SNAPTO. You will not be able to see the points it creates unless you use some sort of a drawing mark. The best thing to use is one of the Marking Symbols included with CPM or you can create your own. (See detailed information about blocks in Chapter IV, section 18.) First put the block into the drawing.  It is not important where you put it, and you can ERASE it right away.  The purpose of this is to add the BLOCK  drawing database. Then SELECT the MEASURE command. The computer will ask:

Select object to measure:
Point with cursor to object. The computer will then ask:
<segment length>/Block:

6.6.1.  If you TYPE and ENTER a number for the segment length the computer will divide the line into segments that length, starting at the end closest to where you pointed when you SELECTED the line. However, you will not be able to see where these measured out point are. You will need to use a BLOCK to show where the point are.

6.6.2.  You can also "show" the computer the length of the segments by SELECTing two points on the line.

6.6.3.  THE BLOCK OPTION allows you to put a SMLDOT  or some other mark or drawn object at the vertex dividing points.  These are handy for using with SNAPTO functions, or, if you had some specific drawn object that was to become part of the pattern, to easily place something at regular intervals. It is perfect for putting in a row of button holes or buttons. You can use any of the SYMBOLS already  in the program or you can make up  your own marking symbol on the spot.
        (See Chapter IV, section 18 for in depth information about BLOCKS.)

6.6.4.  In the MEASURE command , if you TYPE B and ENTER for B(LOCK), the computer will then ask:
Block name to insert:

6.6.4.1.  TYPE the name of the block you want to use, in this case SMLDOT and ENTER.  The computer will then say:
    Align block with object? <Y>
