STL import of number polygon faces

[synt]

hi, i experiences unexpected result when importing STL file of number polygon faces. Example are cylinder look like models, eight number of side displaying properly, but greater number is not. It shown as four face in PrePoMax istead of tweleve as the edges of circle.

hopefully there’s possibility to improve about this without discarding another advantages, thank you.

Do you have mesh display enabled in the Geometry tab ?

shown edges in geometry seems to be displaying properly, but unfortunately the edge faces at intermediate is lost.

maybe it’s related to boundary face normal angle tolerances between neighbor faces in PrePoMax setting internally?

[FEAnalyst]

Can you share the file with this geometry ?

thanks for looking further into the problem, attached PMX files.

Try setting lower value in Tools → Settings → General → Edge angle.

For example, with 5 instead of 30:
