how to know model(3d) space or drawing(2d) space in dxf file
hi,
i have a difficulty.
please see attached drawing which is dxf file.
it has two layouts... one is model space and other is layout.
model has a image which means layout also has image.
now problem is that while vectorisation of these two spaces.
in rasterimageproc... coordinates of image which we get
are as
in model space it gives respective to model space i.e. same like we get for shell 3d.
in layout we get coordinates transformed to 2d viewer space.
second case is ok. i need two solutions for this.
1) how can i transform those coordinates(which i get in model) to 2d viewer space
2) how do i know that which one i am vectorising i.e. model space or 2d layout space.
please help in finding out solution for my queries above. thanks in advance..
