Abstract: For the problem that users cannot import custom models for new industrial production line and the expansion degree is not high in previois industial simulation systemss，a new way is put forward to implement file data parsing and topology analysis for 3D OBJ model，and a topology design class library was disigned based on grid programming model according to Unity3D kernel. What’s more，custom dynamic import and rendering of software were achieved. Experiments and tests verified that the dynamic model import mode based on grid programming workflow is complete，and the overall rendering effect is consistent with that of 3D modeling software on the market. This process solves the problem that the industrial simulation system is unable to build a custom model base and the expansion degree is not high，realizing the multiplatform and multi-format model import of the virtual simulation system.
