invalid input exception with oddbellipse
invalid input exception with oddbellipse
hello,
i am getting an "invalid input" exception on my call to oddbellipse::set(). here is the call:
code:
oddbellipseptr pacadellipse = oddbellipse::createobject();
pacadellipse->set(ptcenter, odgevector3d::kzaxis, majoraxis, dratio);
the values being passed in are:
code:
dratio (double) 0.79313139580935765
majoraxis (odgevector3d)
{x=1.2031781624481199e-009
y=0.00000000000000000
z=0.00000000000000000 }

ptcenter (odgepoint3d)
{x=-122.49798407582628
y=37.851037434628481
z=0.00000000000000000 }
i am aware of the restriction that the ratio must be between 0 and 1 (not a problem in this case), but i do not know what other conditions can cause the invalid input exception. any help you can provide would be greatly appreciated. thanks.
i am using dwgdirect version 2.4.1 and visual studio 2005.

i know ratio must be greater than 1e-06. maybe other parameters should be in the same range.
other conditions are:
code:
unitnormal.dotproduct(unitnormal) < 1.e-12
|| majoraxis.dotproduct(majoraxis) < 1.e-12
|| !majoraxis.isperpendicularto(unitnormal, 1.e-6)
|| fabs(endangle - startangle) < 1.e-6

thanks for the information.
