Abstract: To solve the problem of fast and accurate drawing of section diagrams for beam and plate support formwork, this article uses Python programming language to implement programming. Based on the third-party library ezdxf, standard library functions for various accessories of the beam and plate support formwork system of the plate type steel pipe scaffold, sleeve type steel pipe scaffold, and coupler type steel pipe scaffold are established. The vertical and horizontal rods are matched in the human-machine input interface, and the backend automatically generates a batch of DXF file format diagrams. After the program is packaged, it has been widely applied in practical projects. Practice and research results have shown that software based on Python for automatically generating DXF format formwork profiles can quickly draw various types of beam and slab formwork profiles, which helps engineering personnel understand technical solutions and greatly reduces the labor intensity of scheme developers. This has changed the drawing time from days to minutes. The various library functions of this software can be ported.
