Hi @brad.bylls .

 

It seems that the Tool's SelectionCommandInput is cleared when the first Cut is performed.

Therefore, if I create the ObjectCollection of Tools in advance and process it, no error occurs.

Hi Mr BradBylls,

 

Could we dream that the problem you solved in your script would be found in a future version of the standard F360 combine tool?
