【转帖】dwg file coordinates to world
dwg file coordinates to world
dwg file coordinates to world
hi all,
before beginning writing a lot of wrong code i write a little question here
which is the best way to get world coordinates from dwg file?
the only thing i want to do is:
1) open dwg file
2) go around from dwg elements
3) write down world coordinates of every vertex
thanky you in advance

see our odvectorizeex sample, it solves nearly this task.

the only question is: does a dwg contains world coordinates or do i have to convert them in a few way?
i need to make a simple thing and odvectorizeex seems to makes this in a complicate way....
thank you

in common case, dwg can contain a lot of objects, that can contain absolutely any coordinates. also dwg can contain block references with model transforms and spatial clips. in this case, information, that is stored in dwg, is not in world coordinates.
odvectorizeex is a right way to solve vectorization tasks, other ways are wrong.

ok, i understand this. but vectorization is relative to a "view".
in the case of the example we have a pseudo-view of 1000x1000.
i need to get absolute coordinates instead...
maybe a lost something trying to understand the example?

in exsimpleview::update(), there is a line:
code:
seteyetooutputtransform(eye2screen);
if you substitute it by
code:
seteyetooutputtransform(geteyetoworldtransform());
then you'll get wcs coordinates.

ok, then if i understood well the only thing i have to do is:
1) change seteyetooutputtransform(eye2screen); to seteyetooutputtransform(geteyetoworldtransform());
2) replace all the odgiconveyorgeometrydumper dumper functions with mine "drawing" function
do i forget something?

yes, it is so. you didn't missed anything.
(maybe except some kind of your specific initialization, etc)

another question.......
with your help i finally realize my application...
now i need another little thing:
- when i am in drawing proc in my "odgiconveiorgeometry" subclassed class, how can i know wich is the layer owning the geometry i'm drawing??
thank you again
