Embodiment Construction
[0025] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the following embodiments will specifically illustrate a method for adjusting the serial number position of a three-dimensional digital-analog engineering drawing according to the present invention in conjunction with the accompanying drawings.
[0026] Step 1: Import the 2D engineering drawing into the 3D software. The 2D engineering drawing includes multiple views. There is an outer enclosure line around the periphery of each view. Select the center position O(O, O) of an outer enclosure line, A two-dimensional coordinate system is established according to the center position, and the view is divided into four quadrants in the two-dimensional coordinate system, namely the first quadrant, the second quadrant, the third quadrant and the fourth quadrant.
[0027] Step 2: Divide the first quadrant, the second quadrant, the third quadrant, and the...

According to the method for adjusting the serial number position of the three-dimensional digital-analog engineering drawing, the two-dimensional engineering drawing is imported into three-dimensionalsoftware, the center position of the outer surrounding line of the view and the coordinates of the four vertexes of the outer surrounding line are obtained, the two-dimensional coordinate system is established according to the center position, and the view is divided into four quadrants in the two-dimensional coordinate system; and each quadrant is divided into two regions by taking an angular bisector as a dividing line. The method comprises steps of obtaining the number of serial number labels, serial number positions and serial number attachment positions in a view, determining the areas where the serial number labels and the serial number attachment positions are located, and calculating the equal interval distances between the serial number labels in the x direction and the y direction according to the serial number labels and corresponding vertex coordinates of an outer surrounding line; and automatically adjusting the serial number label and the serial number attachment position to obtain a new engineering drawing serial number position.
Description
technical field [0001] The invention relates to the field of computer-aided design, in particular to a method for adjusting the serial number position of a three-dimensional digital-analog engineering drawing. Background technique [0002] At present, in the field of 3D drawing, the existing 3D drawing tools will generate a large number of engineering drawings in the environment of large assemblies, but the current software has many inconveniences in the drawing of engineering drawings, such as the inability to generate drawings that meet the engineering drawing standards at one time. serial number label (such as figure 1 shown), and then the engineering drafters need to manually modify the annotations of the engineering drawings one by one in the software, which creates a large workload and makes the work efficiency of the engineering drafters low. [0003] Therefore, the present invention designs a method for adjusting the serial number position of the three-dimensional d...
