Hi all,<div><br></div><div>I want to add two surfaces in to a same window. But when I add the second surface the first surface can't be seen. It worked well when I viewed only the points without creating the surfaces. </div>
<div>I have managed to show the two surfaces but in different viewports, but I want to show it in the same where the user can view the relevant positions of the surfaces.</div><div>The code I have done so far is given below.</div>
