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 ?
Put your geometry under a Switch feature (as one group/transform feature)
Type in the name of the Boolean property in the Switch's "Choice" property
Now the property value will be equal to zero when the checkbox (boolean) is not checked and nothing is shown. Checking the property will show the first feature under the Switch. So, in order to show everything in the switch, group all to the first feature as a Transformation.
