• Start of simulation


Mirror to full model

• Duplicate all parts with all options

Select: „Mesh Editing“ Part Duplicate

Mark the highest model hirarchy


„Include selected parts of Tree“

„Mesh + all options“

„Mirror“

„Apply Mirror“

„Save“

• Duplicate all parts with all options


New Assembly:„Duplicated parts“

is created

Nodes at Midplane are

NOT equivalenced !!


• Equivalence at mid/mirror plane


- Select the new (dublicated) „BUMPER

BEAM“ from Tree

- „Mesh Editing“ „Node“ „Modify“
