Tria mesh and free edges

Recommended Posts

Hi guys,

I have  a model composed by about 27 parts. This model is a STEP file. After importing the geometry into Hypermesh, I linked the parts in contact between boolean operations. Now the topology of the model is correct and I have created a 2D mesh of all parts. When I want to create a 3D mesh of all parts by tetramesh command, the status bar shows " Tria mesh and free edges". After  I used Tools > Edges panel for check, there is " no edges were found.Selected elements may enclose  volume". However, when I executed the Boolean operation and used the  tetramesh command directly, I successfully created a  3D mesh of all parts.  Who can tell me the reason? Thanks!
