Abstract
The invention relates to a drawing method for a three-dimensional rebar model schematic diagram, and aims to provide the drawing method for the three-dimensional rebar model schematic diagram. The drawing method is capable of drawing a random shaped three-dimensional rebar model schematic diagram. According to the technical scheme of the drawing method, the drawing method for the three-dimensional rebar model schematic diagram comprises the following steps: A, extracting rebar model information used for reading engineering properties and space geometrical information of a three-dimensional rebar model, and the space geometrical information of the model comprises piecewise numbers and piecewise geometrical properties of the model; B, converting geometric data, and the original three-dimensional geometric data is converted into two-dimensional or one-dimensional geometric data which can be easily demonstrated on a blueprint through coordination transformation and coordination rotation; C, correcting the geometric data, and sequentially carrying out the overall scaling and the piecewise adjustment on a converted two-dimensional or one-dimensional geometric data; D, drawing a rebar schematic diagram, carrying out the drawing of the rebar schematic diagram on each group, and the drawing of the rebar schematic diagram for each group comprises two parts, namely rebar schematic lines and information labels.
