Define line color pointer: yellow is a column, cyan is a beam, and green is a wall; define text color pointer: yellow is calculated for the bottom of the plate and cyan is calculated for the top of the plate.
Traversing lines and characters in the DWG file, and classifying according to defined color pointers: the yellow line is classified as a pillar line; cyan and green lines are classified as support lines; classifying the yellow characters into a plate bottom calculation value; cyan letters are classified as plate top scores.
(2) And analyzing the line data to judge the drawing proportion and correcting.
The drawing scale in DWG calculation may be 1:1, 1:100, 100: 1.
Calculating the length of the column line according to the starting point coordinate and the end point coordinate of the column line data, and judging the proportion according to the length of the column line: when the length of the column line is more than 9000 drawing units, the drawing proportion is 100: 1; when the length of the column line is less than 90 drawing units, the drawing proportion is 1: 100;
if no column sideline exists, the length of 10 sections of support lines is randomly averaged to carry out proportion judgment: when the average line length is more than 30000 drawing units, the drawing proportion is 100: 1; when the average line length is less than 80 drawing units, the drawing proportion is 1: 100; if the support line is less than 10 sections, taking the average value of all the support lines and carrying out proportion judgment according to the method.
The above situation does not occur and the drawing ratio is judged to be 1: 1.
When the drawing proportion is 100:1, reducing the data related to all lines, characters and coordinates by 100 times; when the drawing proportion is 1:100, amplifying the data related to all lines, characters and coordinates by 100 times; when the drawing scale is 1:1, no operation is performed and scaling is not needed.
(3) And matching the plate bottom calculation book through the position data.
