Embodiment 1

[0059] This scheme uses the reference beam method, which completely avoids the shortcomings of non-parameterization, inability to change, no connection between planes, and cumbersome process in the reference plane method. Designers no longer need to complete complicated work and improve the efficiency of roof model drawing. At the same time, the operation items for drawing the roof by the traditional reference plane method are reduced from 15 to 7, and the operation items are reduced from 6 to 2 when changing. For the specific process comparison, see figure 1 . The drawing time is shortened by more than 60% compared with the traditional method, the drawing efficiency is high, and it is not easy to make mistakes.

[0060] The method of using the reference plane has many defects. By using the parameterizable reference beam model surface instead of the reference plane, the steps are as follows:

Embodiment 2

[0088] Embodiment 2 is basically the same as Embodiment 1, and may also include step G after step F, model change;

[0089] 1) Input the new parameters of the height of the end points at both ends of the reference beam model;

[0090] 2) Correspondingly adjust the parameters and positions of each model element on the roof to complete the model change.

[0091] Through the presetting of the scheme, the drawing process is finally simplified, the time for drawing the steel structure slope roof model is shortened, the accuracy rate is improved, and the parametric change of the steel structure slope roof model is realized, so as to improve the drawing efficiency of the steel structure slope roof model the goal of.

Embodiment approach

[0093] Through the above scheme, the steel structure sloping roof drawing template can be constructed specifically, and the specific implementation method is as follows:

[0094] 1. Define the default structural roof elevation, grid and center reference plane.

[0095] 2. Draw the reference beam model, define the default elevation as the structural roof elevation, the default elevation of the starting and ending points, the extension of the starting and ending points, material, structural use and other parameters.

[0096] 3. Draw the default roof beam model, define the working plane as the surface of the reference beam model, the default elevation of the start and end points, the extension of the start and end points, the material, the structural purpose and other parameters.

[0097] 4. Draw 2 default purlins, define the working plane as the surface of the reference beam model, the default elevation of the starting and ending points, the extension of the starting and ending ...

Abstract

The invention discloses a method for rapidly drawing a steel-structure pitched roof model, and belongs to the field of BIM technology application. The problems that in the prior art, a steel-structure model is complex in drawing process, and cannot be changed after drawing, an order cannot be parameterized, and the efficiency is low are solved. According to the method for rapidly drawing the steel-structure pitched roof model, the reference beam model surface is defined as a working plane, pitched roof model primitives are pre-bound one by one, surfaces of all components serve as reference planes, angles and distances between the reference surfaces and surfaces of reference beams are bound, model relationships between all the components of a roof are determined, and a whole beam system and model establishing are completed by defining the roof, defining the roof pitch, drawing roof beams, drawing purlines, drawing tension bars and drawing purlin supports. The method has the advantages that the drawing steps are simple, changing is easy, the order is parameterized, and the efficiency is high.

Description

technical field [0001] The invention relates to the application field of BIM technology, and more specifically, relates to a method for quickly drawing a steel structure slope roof model. Background technique [0002] The traditional method of drawing a steel structure slope roof model in Revit is to first define multiple reference planes with slopes, then load the required model elements, and finally draw the required components on the set reference planes. But building with the reference plane method has various drawbacks and problems. [0003] Using reference planes has the following drawbacks: [0004] 1. Drawing each roof component needs to establish its own reference plane [0005] When drawing a roof steel structure model, it is necessary to bind different model elements by establishing multiple reference planes. [0006] 2. Complicated use of reference planes [0007] The reference plane needs to be strictly defined as a system family in the settings of the Revit...
