[ICEM] Terrible Mesh in the middle slice

Eleven Leo · January 2, 2019, 15:25

This is a 60deg mesh, and it looks fine from outside. However, when you make a slice in the middle of the mesh (i.e., 30 deg), the mesh is terrible, as you can seen. Other slices (e.g., 20, 25, etc) are all OK, only the middle slice is wrong. Anyone can help me find out the reason or possible reason?
Thank you very much for your kind help.

The following are outside mesh and middle slice:

I am not convinced this is a real error. It might be that it is just a matter of inaccuracies when slicing the mesh. Please check the mesh quality perpendicular to this plane: take a z-plane.

Hi Yaopeng,

i agree with Gert-Jan. This is not an error but a property of a slice.

Instead of using a slice, you might should try the feature "Scan planes". It is hidden in the context menu of Premesh - in the model tree.
With this feature you can draw and select specific layers of your blocking.

Best regards,
Sebastian
