Description
Technical Field
The invention relates to the technical field of automatic acquisition of object position information in AutoCAD P & ID, in particular to a refreshing method for object position information of Autodesk AutoCAD P & ID.
Background
AutoCAD P & ID is a design software product based on an AutoCAD platform for creating, modifying, managing pipelines and process flow diagrams. As an important component of the euterk digital plant design solution, autoCAD P & ID can greatly improve the work efficiency of plant designers and easily cope with increasingly complex plant design problems. European Teck provides an easy-to-use two-dimensional and three-dimensional design solution for engineering departments.
Because the area positions of the symbols of the equipment, the valves and the page-to-page connectors in the AutoCAD P & ID are determined according to the area position information formed by the horizontal axis and the vertical axis of the picture frame, for example, when the area position information of one valve needs to be determined, the positioning point of the valve needs to be determined, then each line segment is respectively confirmed to be drawn in the XY two directions to accurately position the area code of the valve in the drawing, finally, the two area codes are filled in the area position attribute, and because the P & ID does not have the function of automatically calculating the position of a special object area, the position is calculated on the drawing object by object and then the characteristic is filled manually at present, the operation efficiency is very low, and if the drawing is too many, the items need to be opened one by one drawing for similar operation.

Take the valve with the coordinate (411.1085,264.6400) in the A1 frame as an example
1. The program can directly obtain the length (h=841), the width (w=594), the center point PCenter (x, y) =pcenter (420.5,297) of the visual port of the frame A1, and calculate the coordinates of the maximum point max_s (x, y) and the minimum point min_s (x, y) of the visual port of the frame A1 according to the above data:
Max_s(x,y)＝Max_s(PCenter.X+H/2，PCenter.Y+W/2)
＝Max_s(420.5+841/2，297+594/2)
＝Max_s(841,594)
Min_s(x,y)＝Min_s(PCenter.X-H/2，PCenter.Y-W/2)
＝Min_s(420.5-841/2，297-594/2)
＝Min_s(0,0)
2. since the distance between the maximum point and the minimum point of the outer frame and the maximum point and the minimum point of the inner frame are fixed, the coordinates of the maximum max_n (x, y) and the minimum point min_n (x, y) of the inner frame can be calculated:
Max_n(x,y)＝Max_n(Min_s.X+H-10，Min_s.Y+W-10)
＝Max_n(841-10,594-10)
＝Max_n(831,584)
Min_n(x,y)＝Min_n(Min_s.X+25，Min_s.Y+10)
＝Min_n(25,10)
3. the average length xLength of the inner frame after 8 equal divisions of the X-axis length and the average length yLength of the inner frame after 8 equal divisions of the Y-axis length can be calculated:
xLength＝(Max_n.X-Min_n.X)/8
＝100.75
yLength＝(Max_n.Y-Min_n.Y)/8
＝71.75
on the XY axis network, the X axis 8 equally corresponds to the designated area A, B, C, D, E, F, G, H, the Y axis 8 equally corresponds to the designated areas 1,2,3,4,5,6,7,8,
4. the valve with the coordinate (411.1085,264.6400) is compared with the minimum point Min_s (0, 0) of the outer frame by the length of equal division to obtain 4.08 equal division of the valve on the X axis 8 and 3.68 equal division of the valve on the Y axis 8, so that the position of the valve on the XY axis network is D4.
The device according to the invention is not limited to the examples described in the specific embodiments, and a person skilled in the art obtains other embodiments according to the technical solution of the invention, which also belong to the technical innovation scope of the invention.
