Why couldn't it calculate a cell by using 'boundary fill' function

[chengmjW2EAH]

Hi guys, 

Fig 1 is the initial surface. I need create a solid backwards based on this shape. It's too irregular to thicken. My solution is use boundary fill. Following is my steps: 1. use its edges extruded a new surrounding surface; 2 create a posterior flat surface. 3. use boundary fill to calculate a cell defined by these 3 surfaces. However it won't work. I couldn't understand and deal with the error ('Error: inconsistent containments on coincident face_face_ints
'). Could someone help and tell how to tackle this issue?

Boundary fill will only detect enclose watertight volume.

You have an unsealed region.

Might help….

This will work if you stitch the complex surface to the extrusion first. See attached file.

In theory what you're trying to do should work but I think boundary fill is working to a higher tolerance than stitch. Stitch starts to fail if you set the tolerance to less than 0.001mm

already fixed, Thank you!
