oddbarc::getparamatpoint question
hi i have these data from oddbarc:
double rad = parc->radius();
odgepoint3d center = parc->center();
double startang = parc->startangle();
double endang = parc->endangle();
odgevector3d normal = parc->normal();
odgepoint3d pt = /*....*/;
double par1,par2;
arc.getstartparam(par1);
arc.getendparam(par2);
double param=0;
odresult res = arc.getparamatpoint(pt,param);
the data values are:
rad: 40.414588972907303
center: x=495.89344056266731 y=90.923630137035630 z=0.0
startang: 4.0108237083319391
endang: 3.7379884491134825
normal: x=0.0 y=0.0 z=1.0
pt: x=519.36595613877898 y=123.82317442534203 z=0.0
par1: 4.0108237083319391
par2: 10.021173756293068
param: 0.95109367600887407
res: einvalidinput
distance between pt and center is:
40.414588972907286405343890311823
i think that pt should lie on the arc and getparamatpoint should not return einvalidinput, but should calculate some param.
can someone please help me in determinig whether this is a bug?
i'm using the dwgdirect version 1.10 (but not yet with the new update)
thanks in advance for any help
regards

error code is returned because point's parameter does not belong to arc's interval:
start <= parameter <= end

hi sergey, on the attached drawing, i receive the same data as indicated in the first post.
the point is in the arc's interval.
can you please take a look.
probably i'm wrong but need to know what it is?..
thanks

this is dd bug in oddbarc::getparamatpoint().
start param 4
end param 9
point's param calculated 0.95
i can send you the fix.
