Embodiment 1

[0099] like figure 2 As shown, in this embodiment, the local map is quickly dimensioned by the mouse track, and the specific batch dimensioning steps are:

[0100] 1. After the user activates the program, record the mouse active path, pick up the axisymmetric center lines of the equipment, pipelines, and building structures that intersect the path, draw the virtual center line Center, and add it to the annotation set together with the picked Center layer line;

[0101] 2. Process the objects in the annotation set, and obtain the endpoint coordinates and midpoint coordinates of the Center line of each annotation object;

[0102] 3. The user interactively executes the labeling to the top of the view, obtains the upper end point of the vertical Center as the labeling point, and performs batch labeling on all vertical Center lines in the labeling set; batch labeling is performed in the same way when labeling is drawn to other directions of the view;

[0103] 4. If the labeling p...

Embodiment 2

[0106] like image 3 As shown, in this embodiment, the local diagram is quickly dimensioned by frame selection or click selection, and the specific batch dimensioning steps are:

[0107] 1. Use the mouse to select (positive or negative selection) or click objects, and select the characteristic objects such as pipes, equipment, building structures, pipe elbows, center lines (line type is CENTER), circles, arcs, and pipe cross-sections. join selection set;

[0108] 2. For feature objects such as pipe elbows, pipe cross-sections, circles, and arcs, the center of the circle is taken as the marking point, and the end point or midpoint of the line is taken as the marking point;

[0109] 3. The user interactively executes the labeling to the middle of the view, and batch labels all vertical Center lines and feature objects in the labeling set according to the labeling points;

[0110] 4. In the present embodiment, the labeling position is located in the view, and the end point and ...

Abstract

The invention relates to a quick dimension labeling method for drawing based on three-dimensional factory design, which comprises the following steps of: drawing three-dimensional factory software setting according to layers, sectioning a plane section drawing, and transferring the plane section drawing into drawing software of a development environment; receiving a user instruction, and activating the rapid labeling program; the objects are selected through mouse paths, mouse frame selection, mouse click selection and the like, and the selected objects are added into a selection set; performing program processing on the objects in the selection set; and dynamically displaying the marking effect, and completing batch size marking. According to the invention, a rapid batch size marking function is added to the BIM three-dimensional drawing technology, the working efficiency is improved, and convenience is provided for users.

Description

technical field [0001] The invention relates to the technical field of BIM three-dimensional pipeline design, in particular to a method for quick dimensioning based on a three-dimensional factory design drawing. Background technique [0002] With the continuous development of BIM (3D digitization of engineering piping) technology, the popularity of 3D factory design software is getting higher and higher, and it has become a necessary design software for engineering companies and large design institutes. [0003] Many engineering companies and design institutes are using 3D factory design software for 3D piping design, but most of the automatic drawing engines cannot meet the drawing requirements for dimensioning. Medium dimension information. Directly using the automatic drawing engine to form dimension annotations may result in low manual recognition rate or incomplete dimension annotation information; however, it takes a lot of time for designers to label dimensions one b...
