Creat surface component in a designated area

[[Wa...]]

Hello Gom team,

      Can I get the point gom.Vec2d (x, y) coordinate which seems is the pixel coordinate in image through a point coordinate (x,y,z) after surface component?  
      Or how to creat surface component in a designated area?
      Thanks.

Hello Wang,

you can get the coordinates even after the creation of your surface for each point, if you export the surface component as a CSV file.

You can also create the surface component in a designated area. You can reach this goal with different selection tools such as selection inside cube. 

For further information you have to ask more precise.

Actually, I want to check the average strain of necking area in tension test automaticly. There are two problem.

First, the tension test evalution script cannot detect the crack area. So I need to creat the necking point manually.

Second, I want to test the average strain of necking area in 1*1mm. And normal facet and distance is 19*16 which the small triangle edge is quite large. 

Then I change to 19*6mm to meet the 1*1mm area. However, creation of the surface component is time consuming and the file is very large. So i want to creat surface component with 19*6mm in a small necking area automaticlly. With this method the file is small and don't need much time.

Is there a method to do this in script?

Thanks in advance.
