the system comprises a demand acquisition unit, a demand analysis unit and a demand analysis unit, wherein the demand acquisition unit is used for acquiring user demands, and the user demands at least need to represent attribute information of a desired BIM component;
the retrieval unit is used for retrieving corresponding BIM components from the BIM component library according to the attribute information of the represented BIM components required by the user, arranging the BIM components in a descending order according to the sizes of the fitting degrees, wherein the BIM component with the highest fitting degree is the target BIM component until all target BIM components required by the user are obtained;
the editing and modifying unit is used for importing the details and the technical standards of the task book, entering an editing interface of the target BIM component and accepting the editing and modifying of the target BIM component by a user; and
and the assembling unit is used for assembling all the target BIM components after the editing and the modification are finished, generating a second BIM structure model after the assembling is successful, and returning to the step to reselect the target BIM components and edit and modify the target BIM components if the assembling is unsuccessful.
9. A computer device comprising a memory and a processor, the memory having stored therein a computer program that, when executed by the processor, causes the processor to perform the steps of the BIM forward design method as claimed in any one of claims 1 to 4.
10. A computer-readable storage medium, having stored thereon a computer program which, when executed by a processor, causes the processor to carry out the steps of the BIM forward design method as claimed in any one of claims 1 to 4.
