Am I the only one having problem with circular shapes ?
When I use democirc.m then nrbplot.m I have a good result but if I try to export it int the iges format it does not look the same.

Thank you !

i found the same question with Roland, it seems that the length of output file name should be equal to 11.

i just simply rewrite the code instead the original code line numbered 152~155 using the following code:

tstr = sprintf('%1.0fH%s,', G{1,2}, G{1,1});
tstr = [tstr,sprintf('%1.0fH%s,', G{2,2}, G{2,1})];
tstr = [tstr,sprintf('%2.0fH%s,', G{3,2}, G{3,1})];
tstr = [tstr,sprintf('%2.0fH%s,', G{4,2}, G{4,1})];
fprintf(fid, '%s',tstr);
len_tstr = length(tstr);
for kk = 1:(72-len_tstr)
fprintf(fid, ' ');
end
fprintf(fid, 'G%07.f\n', Gln); Gln=Gln+1;

it happens that the end line delimiter (?) "G0000001" of the second line does not align with the other delimiters, than some CAD programs (like freeCAD) can not read the iges file. In this case, I just edit the iges file manually, but it would be good to make the output more robust.

Hi, all

I am using NURBS Toolbox and IGES reader for MATLAB. The IGES reader is supposed to read IGES files from CAD softwares and extract geometric info from it. When i try to extract entities 126 and 128 (which correspond to NURBS Curves and surface). I am getting inconsistent results.

for example.

when extracting NURBS from a Cylinder IGS file from solidworks, I am getting no surface at all. When i use Rhino 3D i get a nurbs surface which looks like a cylinder but it's not Circular in shape like the IGES file.

I need to extract a proper NURBS surface that looks exactly like the IGS file

Nice Work!
A few question:
-Do you know how to create triangular NURBS patches?
-How to export multiple surfaces in the same file?

Thanks!
