How to fix(store) 2D grid before suppress lines?

Hi,

Thanks to all of you for your valuable time and efforts putting in helping others.

I have a solid.And i mesh some facets by 2D automesh.Then i suppress some lines in these facets to improve mesh quality.

But i found when i suppress lines,the original 2D mesh will change,the mesh in facet which lines(suppressed) belongs to will disappear.

However,i need original 2D mesh to do some reference.Now i use *feoutputwithdata and *feinputwithdata2 to store original mesh.But the reading and writing file takes a lot of time.

Do you know another method to fix(store) 2D mesh ?I am very grateful for your help!

Thank you very much!!!
