********************** DIMENSIONING ***********************
FLASH! FEATURES 2 DIFFERENT KINDS OF AUTOMATIC DIMENSIONING.
ASSOCIATIVE DIMENSIONING (AVAILABLE IN REGISTERED VERSION OF
FLASH! ONLY) AND NON ASSOCIATIVE DIMENSIONING AS AVAILABLE
IN THIS NON REGISTERED VERSION OF FLASH!. ASSOCIATIVE DIME-
ENSIONING CHANGES AUTOMATICALLY AS GEOMETRY IS STRETCHED.
<end>
THE DISTANCE BETWEEN ANY TWO POINTS CAN BE DIMENSIONED IN
THE CURRENT COORDINATE SYSTEM. ON THE STATUS LINE ABOVE
THE CURRENT COORDINATE SYSTEM IS "METER". ALL SUBSEQUENT
DIMENSIONS ARE THEREFORE IN METERS. LET US DRAW SOME
GEOMETRY ON THE SCREEN AND DEMONSTRATE THIS.
<end>
NOW FROM THE GROUPS AREA MENU LET US SELECT "DIMENSION".
<end>
THERE ARE THREE TYPES OF DIMENSIONING: IN-LINE, OFFSET AND
ANGULAR WHOSE SUBMENU OPTIONS ARE AT THE FAR LEFT BELOW.
THEN THERE ARE THREE DIFFERENT TYPES OF TERMINATORS.
THEY ARE: DOTS, SLASHES AND ARROWS. CURRENTLY THE "DOT"
OPTION IS SELECTED. LET US CHANGE THIS TO "SLASH".
<end>
LET US FIRST DEMONSTRATE "INLIN" (IN-LINE) AND THEN "OFSET"
(OFF SET) STYLES OF DIMENSIONING. WHEN A DIMENSION STYLE
IS SELECTED A SECONDARY SUBMENU APPEARS.
<end>
LET US CHANGE THE CURRENT COLOR FROM RED TO YELLOW. THIS
ACTION FORCES THE DIMENSION TEXT TO BE YELLOW.
<end>
THE DIMENSION LINES AND TERMINATORS CAN BE PLACED ON ANY
LEVEL AS WILL BE DEMONSTRATED LATER. THE CURRENT LEVEL
WHICH IS LEVEL 001 (LV001 ON THE STATUS LINE ABOVE) IS
AUTOMATICALLY ASSIGNED TO THE DIMENSION TEXT.
NOW LET US CHANGE THE LEVEL FROM LV001 TO LV010.
<end>
LET US DIMENSION THE RED RECTANGLE. REMEMBER THAT WE HAVE
SELECTED THE "INLIN" (IN LINE) DIMENSION STYLE.
TO DIMENSION, SIMPLY SELECT TWO POINTS ON THE SCREEN.
THEN SELECT A THIRD POINT ETC. AND A STRING OF DIMENSIONS
APPEAR. LET US USE THE HOOKS BY PRESSING KEY "9"
<end>
NOW SELECT THE UPPER LEFT AND THE UPPER RIGHT CORNERS OF THE
RED RECTANGLE.
<end>
THE SIZE OF THAT SIDE OF THE RED RECTANGLE IS 1.7 METERS.
NOW LET US SELECT THE NEXT THREE POINTS.
<end>
AS IT TURNS OUT THE RED RECTANGLE IS ACTUALLY A SQUARE.
TO ELIMINATE THE WHITE RUBBER BANDING LINE PRESS KEY "0".
<end>
NOW TO TRY THE "OFSET" (OFF SET) DIMENSIONING STYLE LET US
PRESS "." TO ERASE THE CURRENT SUBMENU AND DISPLAY THE
PREVIOUS SUBMENU.
<end>
NOW SELECT "OFSET" AND THE SECONDARY SUBMENU APPEARS.
<end>
TO DIMENSION THE LONGEST SIDE OF THE GREEN RECTANGLE
SELECT THE UPPER LEFT AND THE UPPER RIGHT CORNERS OF THE
RECTANGLE.
<end>
NOW A THIRD POINT MUST BE SELECT WHICH SPECIFIES THE OFF SET
DISTANCE OF THE DIMENSION LINE.
SELECT A POINT ON THE SCREEN ABOVE THE RECTANGLE.
<end>
2.6 METERS IS THE LENGTH OF THE RECTANGLE.
NOW CHANGE THE COORDINATE SYSTEM AND DIMENSION THE LOWER
SIDE OF THE SAME RECTANGLE.
TO DO THIS PRESS "." TWICE TO EXIT "DIMENSION" THEN PRESS
"5" TO ACTIVATE (GO TO) THE CONSTRUCTION AREA AND SELECT
"COORDINATE" FROM THE CONSTRUCTION AREA MENU.
<end>
SELECT "INCHA" (INCHES ARCHITECTURAL).
<end>
TO SELECT THE "DIMENSION" FUNCTION FORM THE GROUPS AREA,
PRESS "." TO EXIT "COORDINATE" FUNCTION.
<end>
PRESS "5" TO GO TO THE GROUPS AREA & SELECT "DIMENSION".
<end>
SELECT "OFSET" AND THE SECONDARY MENU APPEARS.
<end>
SELECT THE LOWER LEFT AND THE LOWER RIGHT CORNERS OF THE
RECTANGLE.
<end>
SPECIFY THE OFF SET DISTANCE BY SELECTING A POINT BELOW THE
RECTANGLE.
<end>
THE LENGTH OF THIS SIDE IS 2.6 METERS OR 8'-6 23/64".
THE OPTION "PARAL" KEEPS THE TEXT PARALLEL TO THE DIRECTION
OF DIMENSION. "PERPN" MAKES TEXT PRINT PERPENDICULAR
TO THE DIRECTION OF THE DIMENSION FOR VERTICAL DIMENSIONS.
HERE IS AN EXAMPLE. LET US SELECT "PERPN".
THEN DIMENSION A VERTICAL SIDE OF THE RECTANGLE.
<end>
THE OPTION "AUTO" WHEN TURNED OFF, ALLOWS USER TO TYPE IN
PLACE OF THE DIMENSION TEXT ANY TEXT VIA THE KEYBOARD.
SELECT "AUTO" TO TURN IT OFF. NEXT DIMENSION THE VERTICAL
SIDE OF THE RECTANGLE AND TYPE IN THE WORDS: ANY TEXT.
<end>
NOTICE THAT THE WORDS: ANY TEXT ARE PRINTED.
<end>
IF THE DISTANCE BEING DIMENSIONED IS AT AN ANGLE, THEN THE
DIMENSION IS WRITTEN AT THAT ANGLE EITHER PARALLEL OR PERPE-
NDICULAR TO THE DIRECTION OF THE DIMENSION.
HERE IS AN EXAMPLE.
<end>
THE LENGTH OF THE LINE IS AS SHOWN. "HORIZ" AND "VERTI"
OPTIONS FORCE THE HORIZONTAL & VERTICAL DIMENSIONS OF THE
DISTANCE BETWEEN TWO POINTS TO BE PRINTED. SELECT "VERTI" &
DIMENSION THE SAME RED LINE. NOTICE THE DIFFERENCE.
<end>
NOW SELECT "HORIZ" THEN "VERTI" AND DIMENSION THE SAME RED
LINE. NOTICE THE DIFFERENCE.
<end>
THE OPTION "UNDO" SIMPLY ERASES THE LAST DIMENSION.
HERE IS AN EXAMPLE.
<end>
NOW SELECT "UNDO" TO ERASE THAT LAST DIMENSION.
<end>
ANGULAR DIMENSIONS ARE CREATED USING THE "ANGLE" OPTION
OF THE SUBMENU BELOW. LET US DRAW SOME ANGLES.
<end>
WITH RESPECT TO THE TOTAL OF 360 DEGREES THERE ARE TWO
ANGLES BETWEEN THESE TWO LINES. ONE IS SMALLER THAN 180
DEGREES AND THE OTHER IS LARGER THAN 180 DEGREES. CHOOSE
"ANGLE" AND SELECT "ARROW" FOR THE TERMINATORS OF THE
ANGULAR DIMENSION.
<end>
WITH THE HOOKS ON, SELECT THREE POINTS AS FOLLOWS: THE
CORNER THEN THE TWO END POINTS. THIS IS VERY IMPORTANT.
HERE IS AN EXAMPLE OF THE THREE POINTS SELECTED IN THE
WRONG ORDER. FOLLOWING THIS EXAMPLE THE OPTION "UNDO"
IS USED TO ERASE THE INCORRECT ANGULAR DIMENSION.
<end>
AS YOU NOTICED THE ANGULAR DIMENSION WAS PRINTED INCORRECTLY
AND THUS ERASED.
LET US CHANGE COLOR AND TRY THAT AGAIN. THE CORNER FIRST,
THEN THE TWO END POINTS.
<end>
THIS ANGLE IS 323.71 DEGREES. LET US TRY THE SMALLER ANGLE.
<end>
THIS ANGLE IS 36.29 DEGREES. AS YOU NOTICED FOLLOWING THE
SELECTION OF THE CORNER THE TWO END POINTS ARE SELECTED
IN A CLOCKWISE MANNER.
ALL DIMENSION TEXT CAN BE ROTATED MOVED OR COPIED USING THE
EDIT FUNCTIONS OF THE SOFTWARE. THE FUNCTION "EDIT TEXT"
CAN EDIT DIMENSION TEXT ALSO.
<end>
THE OPTION "TRMIN" MANIPULATES THE SIZE OF THE TERMINATORS.
OPTION "PARAM" CHANGES THE LEVEL ASSIGNMENT OF DIMENSIONS,
THE COLOR OF THE TERMINATORS AND THE DIMENSION LINES.
THE OPTION "SIZE" SELECTS THE SIZE OF DIMENSION TEXT.
NOTE THAT THE CURRENT FONT IS APPLIED TO DIMENSION TEXT.
