Modification, including modification reinforcing bar numbering, diameter, spacing and quantities etc., its work efficiency is extremely low.
Civil structure is carried out after three-dimensional cloth muscle, need to carry out two dimension to go out figure.If steel is drawn using above-mentioned traditional method
Muscle figure, workload greatly, and partly works and repeats, inefficiency.So needing to enter in existing RC structural model
Row drawer, generates two-dimentional reinforcement drawing, improves work efficiency.Directly on three-dimensional civil structure model, carry out three-dimensional cloth muscle design,
More directly perceived, efficient.At the aspect such as steel project statistics and report generation, can be convenient quick.From presently disclosed document
From the point of view of, there is no general and efficient method or the approach generating two-dimentional reinforcement drawing from threedimensional model.
Content of the invention
The present invention does not have a kind of general and efficient method generating two-dimentional reinforcement drawing from threedimensional model for prior art
Problem, provide a kind of method that two-dimentional reinforcement drawing is generated based on three-dimensional rebar model, the method comprises the steps：
A. parting plane and concrete structural solid are selected, according to described parting plane and concrete structural solid phase intergrowth
Become xoncrete structure line, be the center of circle according to the point that parting plane and three-dimensional reinforcing bar object intersect, with reinforcing bar radius as radius, cuing open
Cutting plane place plane picture circle, the circle of gained is two-dimensional points muscle object, records reinforcing bar object properties；
B. calculate the angle of three-dimensional reinforcing bar axis and parting plane, be less than the situation of set angle in described angle angle
Under, by three-dimensional reinforcing bar Object Projection to parting plane institute in the plane, obtain two-dimensional curve and record reinforcing bar object properties, described
Two-dimensional curve is as two-dimensional line muscle object；
C. two-dimentional reinforcement drawing is generated according to described xoncrete structure line, two-dimensional points muscle object and two-dimensional line muscle object.
Specifically, in step B, calculate three-dimensional reinforcing bar axis as follows with the concrete grammar of the angle of parting plane：
Judge that three-dimensional reinforcing bar axis is space curve or straight line；
If three-dimensional reinforcing bar axis is straight line, directly calculate the angle of three-dimensional reinforcing bar axis and parting plane, if three-dimensional steel
Muscle axis is space curve, then three-dimensional reinforcing bar axis is carried out discrete processes, obtains three-dimensional point set, calculates from three-dimensional point set coordinate
Obtain mean level of the sea, and calculate mean level of the sea and the angle cuing open plane section.
Specifically, step B also includes：The attribute information of three-dimensional reinforcing bar is stored corresponding two-dimensional points muscle object or two-dimensional line

Present invention has the advantages that：Achieve and generate two-dimentional reinforcement drawing from three-dimensional rebar model, according to being remembered in X-Y scheme
Record reinforcing bar information generate reinforcing bar mark and bar list, by the concordance of model and drawing it is ensured that reinforcing bar X-Y scheme just
Really property, improves design efficiency and designing quality.The present invention is unrelated with software platform, has important answering in engineer applied field
With being worth, and there is applicability and admissibility.
Specific embodiment with reference to embodiments is described in further detail to technical scheme it should note
Meaning, embodiment is used for the purpose of the technology design helping reader to more fully understand the present invention, not in order to limit the present invention
Scope of the claims.
