Hello Max,
thanks for your reply. I've posted these two files. http://moi3d.com/forum/index.php?webtag=MOI&msg=7777.119
Please have a look at the line " this.internal = {filletEdgeNames: [0]};" in the construct2.js and the corresponding line
"internal":"filletEdgeNames":0,"EcHB1E_E3","EcHB1E_E12","EcHB1E_E21","EcHB1E_E30","EcHB1E_E39","EcHB1E_E48","EcHB1E_E57","EcHB1E_E66","EcHB1E_E75"]}}

If I would erase the default 0 in " this.internal = {filletEdgeNames: [0]};" and store the node file, only the first value "EcHB1E_E3" will be restored from file.

Any idea?

Have a nice day
Karsten
