I found a convenient way to simulate my own conveyor .
Let the conveyor of VC type that has been set up size as a kind of logic, then input my model . After aligned, hide the VC conveyor.
But, for now , I could only hide the VC type in modeling tab, but sometimes ,it’s not convenient .If i hide the whole component, the part which is Conveying will hide too.
The work process has a option on properties to hide model without component.
So, is there anyway to model the component to add the option ?
