How to delete the edges or lines on the surface when I import a .stl file
Hi all,
I am using Hypermesh of version 2017.2 to process a geometry.
We used Meshmixer to generate a surface geometry and export as the .stl file. However, the Hypermesh just regards .stl file as mesh when importing the file to it. And it looks like this after import:
I want to convert it into geometry first. So this is what I do:
Geometry > creat > surface > from FE
This is the setting of from FE:
The surface looks like this:
My questions are
1 What the points are on the surface? They are made by Hypermesh?
2 How to delete the edges on the surface? Because I need to assemble this geometry with another later, and the edges are redundant and a big problem for me to mesh in the future. And I have imported the .stl file into Comsol, and it regards the surface as a whole without edge. So I think the edges might be the features recognized by Hypermesh.
Thanks a lot!

Use "toggke edge" to disable edges; "add/remove point" to remove points if necessary.
Hi,
Thank you so much for the quick reply. I have toggled edges in this model. It looks like this:
It seems that the solid lines become dash lines and only one surface left indeed. Could I delete them and what they are?
Then I try to mesh it:
But get the report:
Error identifying faces
Is this related to the dashlines? Thank you.
I don't think disable all edges is a good idea. Try small area, step by step. No way to do this work automatically.

Thank you. But there are too many edges (23197) on the surface. Is there any way to suppress the number of edges or any other geometry format more suitable for Hypermesh than .stl?
For CAD "neutral" format, it's better to work with STEP, IGES or Parasolid.

Thank you very much. We manually process the model and find a way.
