Hello,

when I used the new MLCAD arrows in submodels, I always had one problem: I
couldn't ghost them. Only MLCAD interpreted the ghosted arrows correctly, the
other programs (LPub, LDView...) didn't. Where's the problem?
MLCAD does not ghost the arrow itself (drawn with triangles and quadrilaterals),
but only the 0 MLCAD ARROW command.In plain text, the arrow looks like this:

0 GHOST 0 MLCAD ARROW 11 0 0 98 0 0 -1 0 1 0 1 0 0  10 4 12 20  3 30 1 2  16 16
0 MLCAD SKIP_BEGIN
3 11 0 0 86 0 -5 101 0 0 96
3 11 0 0 86 0 5 101 0 0 96
3 11 0 0 96 0 -2 98 0 2 98
4 11 0 -2 98 0 -2 118 0 2 118 0 2 98
0 MLCAD SKIP_END

But when we want a correctly ghosted arrow, we need to type in "0 GHOST" in
front of command line 3-6:

0 GHOST 0 MLCAD ARROW 11 0 0 98 0 0 -1 0 1 0 1 0 0  10 4 12 20  3 30 1 2  16 16
0 MLCAD SKIP_BEGIN
0 GHOST 3 11 0 0 86 0 -5 101 0 0 96
0 GHOST 3 11 0 0 86 0 5 101 0 0 96
0 GHOST 3 11 0 0 96 0 -2 98 0 2 98
0 GHOST 4 11 0 -2 98 0 -2 118 0 2 118 0 2 98
0 MLCAD SKIP_END

So if you want to render an instruction of a MOC with ghosted arrows using LPub
(I use version 2.1.0.6), you have to do this - only then the arrows will be
shown in the right steps.
I don't know if this problem is fixed in newer versions of LPub (I'm using Win
ME, so unfortunately I cannot use the new beta version).

Happy New Year

(...) Previous to the arrow generation version of MLCad, GHOST only applied to the line in which it is specified. It had no impact on any other lines. Now the definition of GHOST has changed. GHOST on the MLCAD ARROW line *implies* ghosting on the (...) (20 years ago, 30-Dec-04, to lugnet.cad)

Hi Michael, Is it possible for you to let us know about changes like this (the redefinition of the function of GHOST) so we can make updates in a coordinated way? I'm really happy to see arrows handled in MLCad, but learning about their function and (...) (20 years ago, 30-Dec-04, to lugnet.cad)

Hello again, I wrote a little DOS program which does the ghosting automatically. You just have to type in the file name with its path and the programme will create a file called [filename].ghs. Then you have to change the name of this file (for (...) (20 years ago, 1-Jan-05, to lugnet.cad)
