默认 【转帖】remove from dxfdwg file

remove from dxf/dwg file
remove from dxf/dwg file
hi!
i抦 about to remove layers among other things from a file. i have no problems with removing it from the screen (hiding). what i need to do is actually to physically remove the entire layer from the dxf/dwg file, not only some kind of hiding process. i have tried
code:
oddbobject::erase()sure it does a great job of hiding but as far as i can understand there抯 no deletion in the file or i'm i wrong?
have a nice day!
kennet
this thread pretty much covers what i want to do:
see post #6:

i'm trying to delete all of the entities in invisible layers, then those invisible layers themselves.

hi again!
i've hidden layers using;
code:
player->setisoff(!player->isoff());no problems and i also have my layer box correctly updated. now i use the erase option to mark layers for later deletion when saving the file. if i understand this correctly everything in the "erase" - marked layer will be removed during the saving procedure.
right now i'm struggling with a strange phenomenon. if i do a refresh when a layer has been hidden and the erase flag has been sat the layer turns up and it has the colour of the layer next to it, in the order they are found in the dxf-file.
i have added a couple of images to illustrate what happens. the lines are a bit blurred but i think they'll do.
it seems as if the line is drawn with the colour of the previous layer when the erase flag has been sat. i thought that layers that were marked for erase would automatically have their entities marked as well. they are after all under the same roof so to speak. to some extent this must be trough since the colour has been lost.
please give me hint were to start with this problem.
best to you all

erasing a layer does not erase the entities on it. the drawing gets invalid - where are entities referencing erased layer.
