Abstract: The present disclosure provides a BIM component creating method, a digital design resource library application method, and a digital design resource library application device. By displaying recommended creation orders in a recommendation interface for a user to select, the user directly selects a recommended operation order in the recommendation interface, which, compared with selecting an order of next step from an order library, has higher selecting efficiency, and can improve the creating efficiency of the BIM component. Besides, in creation and application of a digital design resource library, a plurality of different creating modes are used for implementation. On the basis of improving the BIM component creating efficiency, the efficiency of creating the digital design resource library is further improved. Moreover, through bulk addition of parameters to the BIM component, geometric parameter visualization verification is performed on the BIM component.
