How do I generate a XY graph from a 3D object

[madame]

I'm trying to get a 2D projection of a section of any stl object. I open the stl file and have a clip plane that cuts the object at any point. Then I was trying to get the object's section that is drawn in this clip plane.

But instead of that I just get a single point in the XY graph.

Could you guys help me?

Hi,

I have no experience with what you are doing - but I can point out some obvious flaws in the code.

In "clip plane" event frame, the property node you use to obtain x and y input for your build xy graph only gives you the size of your window inside the 3D element: width and height.

When fed into the build xy graph this gives only one point. The x and y inputs of the build xy graph would have to be arrays to produce more than one point.

Additionally I think the create clip plane vi doesn't do what you expect it to do - read the help for that vi thoroughly.

As Florian mentionned, you are feeding a scalor for X & Y, thus a single point.

I'm trying to figure out where you're supposed to get your 3D data from...  Can you shed some light on what the code is supposed to do and where the values are from?

First I tried to generate 4 viewports, but I failed. Then I tried to generate a 2D projection of an object slice made by a clipping plane. What I am trying to do is to take measures from this slice, that's why I was trying to use a XY graph

This is something just like I was trying to do:

"3D Vision Advanced Toolkit For LabVIEW" have this Fuction!

I developed a body measurement software using this toolkit.
