Hello i've generated this code to creat the borderlines and center line of a vertical curve road. Basicly i want to creat the contours through the road so as far as i understand i have to creat first the surface of the road. I am not very familiar with the plots of matlab so if anyone have any ideas to creat the surface and or the contours of the road would be really healpfull. A perfect senario would be someone to reveal me how i can transfer the hole project in an autocad drawing. %MILEAGE start position of the road XB1=0; %road wide bl=20; %longitudinal to the road slopes s1=0.02; s2=-0.02; %vertical to the road slope e=0.025; %Height of start position of the road HB1=10; %Radius of the curve of the road Hw=3000; %Tangent length T=(Hw/2)*(s1-s2); %2*T=Total milage curve length % milage end of the road XB2=XB1+2*T; %rates of quadratic parabola a=(s1-s2)/(2*(XB1-XB2)); b=s2-2*a*XB2; g=HB1-a*XB1^2-b*XB1; %Quadratic parabola H= @(x) a*x^2+b*x+g; i=0; L=zeros(((2*T)/0.1),3); for x = XB1 : 0.1 : XB2 i=i+1; %L(i,x,y,z)=[x,y,z of center line of the road] L(i,:)=[XB1+x,0,H(x)]; end % X Y Z Center line of the road x=L(:,1); y=L(:,2); z=L(:,3); % Υ Ζ Right Borderline yr=y+(bl/2); zr=z+((bl/2)*e); % Υ Ζ Left Borderline yl=y-(bl/2); zl=z-((bl/2)*e); hold on %plots center line left borderline and right borderline plot3(x,y,z) plot3(x,yl,zl) plot3(x,yr,zr)
