Abstract

The invention relates to the field of building construction, in particular to a method and a system for automatically generating drawings of a three-dimensional light steel keel wall model based on Revit. A drawing automatic generation method of a three-dimensional light steel keel wall model based on Revit includes the steps of generating a drawing in a unit of a room in a plan view after the three-dimensional model is generated in Revit, selecting or drawing out a specific area as the room and naming the room, generating a view number of each view based on the room naming, selecting the room for creating a vertical view, generating the vertical view of the room, wherein the plan view comprises the view number of each vertical view, selecting a required view and marking the selected view according to default drawing setting, then selecting the required view to be arranged in a preset frame to generate the drawing, and hiding a sealing plate on a wall when the vertical view is generated. And further, the problem that in the prior art, a designer still needs to draw a two-dimensional drawing manually after generating a three-dimensional model is solved, so that time and labor are wasted.

Description

Drawing automatic generation method and system of three-dimensional light steel keel wall model based on Revit Technical Field The invention relates to the field of building construction, in particular to a method and a system for automatically generating drawings of a three-dimensional light steel keel wall model based on Revit. Background In the construction process of a building site, a constructor needs to carry out corresponding construction according to a drawing, and the drawing is generally provided by a designer. Three-dimensional models are powerful tools for space conception, professional coordination and scheme optimization by designers, and for this reason, the designers often draw three-dimensional models when drawing or generating drawings. The three-dimensional model is convenient to view, but the three-dimensional model is generally not provided with dimension marks, and because constructors need to print on drawings when viewing on site and carry dimension marks, after the three-dimensional model is drawn, a designer needs to draw a two-dimensional drawing again, so that the constructors can view the drawing conveniently, and drawing approval and data archiving are carried out. Redrawing is time consuming and labor intensive and may even affect the construction period. Disclosure of Invention In view of the above, the invention provides an automatic drawing generation method of a three-dimensional light steel keel wall model based on Revit, which is used for solving the problem that in the prior art, a designer needs to draw a two-dimensional drawing manually after generating the three-dimensional model, so that time and labor are wasted. A drawing automatic generation method of a three-dimensional light steel keel wall model based on Revit includes the steps of generating a drawing in a Revit, taking a room as a unit to generate the drawing, selecting or drawing out a specific area as a room and naming the room, generating view numbers of all views based on the room naming, carrying out default drawing setting, selecting a room for creating a vertical view in a plane view, generating the vertical view of the room, wherein the plane view comprises view numbers of all vertical views, selecting a required view and marking the selected view according to the default drawing setting, then selecting the required view to be arranged in a preset drawing frame to generate the drawing, wherein the default drawing setting comprises marking types and drawing frame information, and hiding sealing plates on walls when the vertical view is generated. Further, the view numbers of the corresponding walls are ordered sequentially clockwise or counterclockwise along the room in which they are located. Further, when the selected room has a plurality of rooms, the rooms are named sequentially in a clockwise or counterclockwise direction. Further, the view name of the elevation view is automatically generated according to the wall position, and the view name comprises a view base name, a room name and a wall view number. Further, the default map setting also includes keel parameters including cross keel parameters, vertical keel parameters, pass through keel parameters, and connector parameters between keels. Further, when the video is marked, the sizes of the door and window openings are marked on the left side and the lower side of the inside of the position of the opening, the other openings are marked on the left side and the lower side of the outside of the position of the other openings, the other sizes are marked on the left side and the lower side of the corresponding drawing, and the keel parameters are marked on the right side. Further, the drawing ranges of the elevation view and the plan view of the room are defined by 100-200mm outside the wall body connecting point or the wall body elevation line. Further, when naming rooms, each room is automatically identified according to the closed primitive model, or a specific space including the primitive model is drawn by a separation line. The automatic drawing generation method based on the Revit three-dimensional light gauge steel wall model has the advantages that the light gauge steel wall three-dimensional model generated in the Revit is used as a basis, the generation of drawings is facilitated through selection or demarcation of the generation range, the problems that the workload is large and the drawings are difficult to distinguish due to the fact that all parts are generated once are avoided, the naming of rooms is correspondingly carried out, the view naming of the walls forming the rooms is correspondingly carried out, the distinction between the rooms and the walls is facilitated, after the generation, the elevation view of each wall can be found according to the name, the drawing is set in a proper drawing proportion and in a labeling mode, the generation of the plane view and the elevation view is facilitated due to the fact that the gener
