DMM Varkon® Tutorial
A Beginner's Guide to the Varkon Parametric Modeling and CAD Application Development System
By David M. MacMillan
The following MBS module shows a vertical stack of width 0 (i.e., as thin as possible) lines through a range of lfonts (line styles). Lines are displayed with the lfont number on the left.
The calling syntax is:
showlfonts (firstlfont, numlfonts, lfontspacing, lfontlength);
All parameters are integers.
! Draw examples of all lfonts (line fonts, which are line styles)
global drawing module showlfonts(
vector start, stop;
float x1, y1;
float x2, y2;
float dx, dy;
dx := lfontlength;
dy := lfontspacing;
x1 := 0;
y1 := 0;
x2 := x1 + dx;
y2 := 0;
for ix := firstlfont to (firstlfont + numlfonts - 1) do
y1 := y1 + dy;
y2 := y2 + dy;
start := vec (x1, y1);
stop := vec (x2, y2);
textpos := vec (x1 - 5, y1);
text (#3, textpos, 0, str(ix, 2, 0): tsize=2);
lin_free (#4, start, stop: width=0, lfont=ix);
To invoke this module to display the lfonts from 0 to 4 (5 lines total), use, for instance, an active module containing:
GLOBAL DRAWING MODULE test2d();
part(#1,showlfonts(0, 5, 5, 40));
lfonts greater than the highest lfont defined default to blank. (They plot blank as well.) In this example, lfont 3 is the highest numbered lfont defined.
