uninitialized values passed to circleproc()
uninitialized values passed to circleproc()
hi,
we are using dd libs 1.14.02.
for the attached r12 file, when we import "layout 1", the values passed for center and normal paramertes to one of the calls to my circleproc() by the vectorizor are what looks to be uninitialized.
here is a dump of the watch window from vc8.
code:
- center {korigin={...} x=-1.#ind000000000000 y=-1.#ind000000000000 ...} const odgepoint3d &
+ korigin {korigin={...} x=0.00000000000000000 y=0.00000000000000000 ...} odgepoint3d
x -1.#ind000000000000 double
y -1.#ind000000000000 double
z -1.#ind000000000000 double
radius 0.057718428674495441 double
- normal {kxaxis={...} kzaxis={...} x=-1.#ind000000000000 ...} const odgevector3d &
+ kxaxis {kxaxis={...} kzaxis={...} x=1.0000000000000000 ...} odgevector3d
+ kzaxis {kxaxis={...} kzaxis={...} x=0.00000000000000000 ...} odgevector3d
x -1.#ind000000000000 double
y -1.#ind000000000000 double
z -1.#ind000000000000 double
- pextrusion 0x00000000 {kxaxis={...} kzaxis={...} x=??? ...} const odgevector3d *
+ kxaxis {kxaxis={...} kzaxis={...} x=1.0000000000000000 ...} odgevector3d
+ kzaxis {kxaxis={...} kzaxis={...} x=0.00000000000000000 ...} odgevector3d

in circle import i call the perpvector() method which throws an invalid input exception with the following stack:

the problem is happening with the xcode build as well.
when i save the file with autocad 2005 into autocad 2004 or 2000 file format and open the file, it imports without any problem.
can you guys help identify the problem?
thanks,

hi,
any updates on this?
thanks,
varun
is it possible to reproduce the problem in any of our samples? odamfcapp seems to render the layout correctly.
probably you have not set up view properly.
sergey slezkin
hi sergey,
you were right! the setwidth() and setheight() of overallviewport were being called with zero values.
the values returned by getlimmin() and getlimmax() for this layout are zero. why does this happen for some files? and how can we find out the width and height of the paperspace layout correctly?
thanks,
varun
limmin - limmax can be set to zero even in autocad.
they simply store grid limits.
what do you mean by "width and height of the paperspace layout"?
- extents of paper space entities?
- size of paper?
- overall view (area visible on screen)?
they are different.
sergey slezkin
i was referring to the first one: extents of paper space entities. it would be very instructive to me if you could enumerate how to get all three of them.
thanks,
varun
hi,
now i am using oddbviewport::height() and oddbviewport::width() instead of limmin and limmax. however i am still confused over the following points:
1. what is zoomextents() supposed to do when called on a overall viewport of a paperspace layout?
2. comments above functions oddbviewport::height() and oddbviewport::width() say that the value returned must be divided by a factor of 1.058 for overall viewport. why is this? what does this new value signify?
thanks,
varun
