never returning function ending in external exception
never returning function ending in external exception
hi guys,
i have a very hard circumstance. we have a series of very confidential drawings, so i cannot send these for you to reproduce. however i am hoping that from the following information that you maybe able to solve the problem.
using is 1.14.2 of the opendwg libraries and after calling m_blocktableptr->getgeomextents(m_odblcktbleexts); the function never returns with the following callstack if i press break into the debugger.

if i let the program continue running, and break again, it is always around this same area of code in opendwg. if this program continues long enough it will end in an external exception thrown.
the second bit of information i have that maybe able to help is that these drawings work perfectly fine with version 1.14.1. what i mean by this is if the same line of code is called using the 1.14.1 libaries, it works perfectly fine.

hi,
i need file. i think, that problem is in acis rendering. you can attach file with bad entity only. for example, remove all non solid entities from file. try to locate bad solid. copy it to new drawing. also you can explode solid to parts and attach(or email directly to me) invalid part.
thanx for your reply, but i have a problem with this method.
the moment i open it in autocad, and save it again, fixes the problem??
even if i do not change the drawing at all, all i have to do is load it into autocad, save it again, and opendwg 1.14.2 loads it fine?
any other suggestions on how i can get this problem entity to "remain" a problem?
cheers

ps. sorry for sounding unco-operative, but i just cannot send the drawing, else i would for ease of reproducing the problem.
try to save it to dxf, not to dwg. it will disable autocad geometry cache for 3dsolids. is 1.14.2 throw exception with dxf ?
could you attach log of call stack in case of exception ?
