I have a geometry that consists of contours of xyz data points, I want to allign it in such a way that the inlet(left side) is perpendicular to the z axis so that the lenght of the geometry is along the z-axis. Can anybody help?

Thanks!

How is your question related to MATLAB?

Do you attain the figure by MATLAB code? If so, then provide the code and relevant data used.

for i=101:171;

plot3(dab.SegmentInfo(i).branch1(:,1), dab.SegmentInfo(i).branch1(:,2),dab.SegmentInfo(i).branch1(:,3)); hold on; --> blue in image

plot3(dab.SegmentInfo(i).branch2(:,1), dab.SegmentInfo(i).branch2(:,2),dab.SegmentInfo(i).branch2(:,3)); hold on; --> green in image

end;

for i = 173:435

plot3(dab.SegmentInfo(i).main(:,1), dab.SegmentInfo(i).main(:,2),dab.SegmentInfo(i).main(:,3)); --> black in image

end

Colours in the figure are after the line, so the data consists of three parts and these consist of countours (xyz values for the points in the contours)
