PropertyManager Combiner
In the Combine PropertyManager , you specify the bodies that you want to add, subtract, or overlap in a multi-body part.
To open this PropertyManager :
In a multi-body part, click Combine (Functions toolbar) or click Insert > Functions > Combine .
You can only combine bodies contained in a multi-body file. You can't combine two separate pieces. However, you can create a multibody part by using the Insert Part option to place one part in the other part file. You can then apply the Combine option on the multibody part.
