Identifying the position of a component on the PCB

hello How can I be sure that a component will be installed in the correct position on the PCB? I mean square SMT components which apparently can be placed in four different configurations and geometrically look the same in any position you place them only the distinction in the tiny dot at the end of the component points to pin number 1 Or diodes and LED and so on Requesting information in order to complete everything required to send a work file for the production of PCB boards including the installation of the components without faults Sincerely Gabriel Toito
