# 4.5.9 Spatial Separation The spatial separation during actual manual loading, the cargo expansion, and sometimes buffer materials added between the cargoes, such situations can be simulated by the setting the \[Spatial Separation]. Manual placement intervals and cargo expansion can also be simulated by setting a reserved size on the container page. For details, see “Reserved Size” above. You can choose one of the two methods. If you need to control the center of gravity, it is recommended to use \[Spatial Separation] to simulate. \[Spatial Separation] is an empirical value, and you can try to find the most appropriate value by using LoadMaster for several times. The recommended setting for the first use is about 1cm. ![](/files/-MDxZBX1BM36X63oLvcV) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://doc.loadmaster.biz/4-ui-and-terminologies/4.5-loading-rules/4.5.9-spatial-separation.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
