The invention discloses a visualization programming platform based on a mobile terminal and a two-dimensional drawing three-dimensional visualization method, belonging to the technical field of building engineering. the visualization programming platform based on the mobile terminal, comprises a basic module being realized by a Unity 3d development platform; a parameter configuration module, configured to provide an annotation card picture; an interactive module, being realized by Unity 3d development platform and PlayMaker visual programming module. The two-dimensional drawing 3D visualization method based on mobile end, includes: importing the three-dimensional building information model into the Unity 3d development platform and setting corresponding relationship between two-dimensionalconstruction drawings and three-dimensional building information model on Unity 3d development platform, After scanning the two-dimensional construction drawings by the moving end, displaying the corresponding three-dimensional building information model on the screen of the moving end, and making the explosion effect animation and restoration effect animation of the three-dimensional building information model by the visual programming platform, so as to realize the three-dimensional display of the two-dimensional construction drawings on the moving end.
