a problem about hatch
hi, i use following code to read "oddbhatch" object's boundary:
oddbhatchptr ptroddbhatch;
int inumloops = ptroddbhatch->numloops();
for (int i = 0; i < inumloops; i ++)
{
odint32 ilooptype;
ilooptype = ptroddbhatch->looptypeat(i);
if (ilooptype & oddbhatch::ktextisland)
continue;
if (ilooptype & oddbhatch::kpolyline)
{
......
}
else //read as edge
{
......
}
}
i open the dwg file in attach files by this section code, the result is like as hatcherror.jpg in attach files. but i open the dwg file by acad, the result is like hatch.jpg in attach file.
are there some problem in my code?

in this code i cannot notice any significant problems, but it seems you missed something in your hatch vectorization (dd vectorizes this file successfully).
sincerely yours,

hi, george
i don't understand what's mean the missing something. i want to get the correct hatch's loop information. when i exclude some loop type, it seems right. why?
if autocad and odamfcapp renders the hatch correctly and your application not - obviously where is a problem in your code processing loop information.
but it's impossible to say what is wrong because i see no code processing the hatch....

the attach file(hatchdumper) has a particular code's example.
