The following is a detailed illustration of the solution of the invention in conjunction with the drawings:
the method is realized by a program, and the process is as shown in fig. 2, and steps S101 to S107 are penetrated from the beginning to the end:
step S101:
setting the parameters of the loft map, the scale of the loft map and the offset distance distatch, in this embodiment, for example, scale is set to 0.5, and distatch is set to 60 drawing units.
Step S102:
and picking up the detailed graph contour lines to obtain a detailed graph contour line set outLines, a contour vertex set outPts, a contour line central point cpt, all stirrup graphic primitive sets stics and a stirrup graphic primitive set ties in the contour.
The detail drawing of the edge component to be lofted is shown in fig. 3, and the extracted contour line sets outLines, namely { line AB, line BC, line CJ, line JE, line EF, line FI, line IH, line HA }, vertex sets outPts, namely { a, B, C, J, E, F, I, H }, in-contour stirrup primitive sets stics, namely { stirrup ABCH, stirrup EFGD }, stirrup sets ties, namely { stirrup (1), stirrup (2), and stirrup (3) }. In fig. 3, the detail drawing is composed of a broken line element, a multi-sense line element, a point rib element (also called a longitudinal rib element), a tie rib, a stirrup element, and a broken line element. The shape, size and position of each primitive are determined by the control point of each primitive; the pattern and control points of each primitive are shown in fig. 4.
Step S103:
the distance reinDis between the contour line and the rebar primitive is found as follows.
Traversing stirrups and lacing wires, wherein the minimum value of the distance from the control point of each graphic element to the contour line is marked as eleplas, the maximum value of the eleplas of all the control points of the graphic elements is used as the distance from each graphic element to the contour line, and the maximum value of the eleplas of all the graphic elements is the required reinplas, and the meaning of the minimum value is shown in figure 5.
As shown in fig. 6, assuming that PtA is a control point of a certain primitive, the vertical foot from the point to all contour lines is { PtB, ptC, ptD, ptE, ptF, ptG, ptH }, the nearest distance between the point and PtA is recorded as the minimum value of the distance between the control point and the contour lines, and the above steps are repeated until the maximum value of the elePtDis of all control points of a primitive is obtained as the eleDis of the primitive, and then the maximum value of the eleDis of all primitives is obtained, thereby obtaining reinDis.
Step S104:
finding out each big hoop from the hooping graphic element according to a certain rule, and moving each big hoop to the constructed big hoop set. And sequencing the large hoops according to the number of edges overlapped with other large hoops and the area, wherein the stirrup with the largest area and the largest overlapped edge is the largest overlapped large hoop.
The rules for finding each big hoop are as follows:
traversing the stirrup primitive set, and solving the distance ptDis between the ith control point and the jth profile vertex, wherein the jth profile vertex is a vertex shared by profile lines LineA and LineB, the included angle between LineA and LineB is alpha, if ptDis is smaller than reinDis/sin (alpha/2), marking the control point, and when the control point of the stirrup is more than or equal to 2 such marking points, considering the stirrup as a big hoop, removing the stirrup from the stickers, and adding the stirrup into the bigStirs set.
As shown in fig. 7, the distance between the control point of the stirrup primitive and the contour point is the distance between ptA and cptA, the included angle between two contour lines including the ptA vertex is α, the minimum value between cptA and the contour line should be within the reinDis range, if the relationship is shown, the distance between ptA and cptA must be less than reinDis/sin (α/2), so the criterion is used to determine whether the relationship between a control point and a contour vertex is the positional relationship of fig. 6.
According to this rule, stirrups ABCH, GDEF are selected as big hoops, as shown in FIG. 3, stirrups ptA-ptB-ptI-ptJ, stirrups ptJ-ptK-ptD-ptE, and stirrups ptG-ptL-ptD-ptF are big hoops.
Traversing the bigStirs set, judging overlapped edges between big hoops in pairs, and finally counting the number of the overlapped edges of each big hoop, wherein the overlapped edges of big hoops ptA-ptB-ptI-ptJ are ptJ-ptK, ptI-ptJ and 2 overlapped edges in total as shown in fig. 8; the overlapping edges of the big hoops ptJ-ptK-ptD-ptE are ptJ-ptK, ptI-ptJ, ptL-ptD, ptE-ptD, and 4 overlapping edges in total; the overlapping edges of the large hoops ptG-ptL-ptD-ptF are ptL-ptD, ptE-ptD for a total of 2 overlapping edges, so the stirrups ptJ-ptK-ptD-ptE are the largest overlapping edges. Similarly, as shown in fig. 3, the overlapped edges of the big hoop ABCH and the big hoop GDEF are GD, and are 1 overlapped edge, and then the big hoops are sorted according to the area size, and if the area size is the same, any big hoop is selected as the largest overlapped big hoop.
Step S105:
and determining the movement amount of each large stirrup in the X and Y directions according to a certain staggering principle and a set stagger distance distatchDis.
The staggering principle is as follows:
the maximum overlapped big hoops move the distance of the deltatchDis along the normal positive direction of the overlapped edge (namely, the direction of the overlapped edge with the normal vector of which the included angle with the Y positive direction is not more than 90 degrees and the included angle with the X positive direction is not more than 90 degrees), the rest big hoops move the distance of the deltatchDis along the normal negative direction of the overlapped edge, then the rest big hoops are checked for the overlapped edge, if the rest big hoops still have the overlapped edge, one big hoop is selected, and the distance of the deltatchDis is continuously moved along the normal negative direction of the overlapped edge.
As shown in FIG. 8, the maximum overlapping macrocuffs are ptJ-ptK-ptD-ptE, the normal positive direction of the overlapping edges is directA and directC, respectively, the normal negative direction of the overlapping edges of the remaining macrocuffs is directB and directD, respectively, and the remaining macrocuffs have no overlapping edges, so that no further movement is required.
Step S106:
and (3) taking cpt as a scaling point for all the reinforcement primitives in the large hoop set, the stirrup set and the lacing wire set, scaling scale times, and moving the scaled large hoops according to the movement amount determined in the previous step to finish drawing of the lofting drawings.
The zoom movement is followed by the zoom movement as shown in fig. 9.
Step S107:
the lofted stirrups and ties are processed according to the following rules, and the drawing of the lofted drawings in this case is completed.
Searching for a broken line drawing element on a contour line, changing a big hoop nearest to the broken line into a wall distribution rib, deleting the big hoop, generating a lacing wire at the position of a control point of the big hoop, searching for a graphic element nearest to the broken line and located in the range of the deleted big hoop, deleting the lacing wire if the graphic element is the lacing wire, generating a new lacing wire at the positions of the lacing wire and the control point of the deleted big hoop nearest to the broken line, and generating a new lacing wire only at the position of the control point of the deleted big hoop nearest to the broken line if the graphic element is the lacing wire.
As shown in fig. 9, the big hoops closest to the break line are (1) and (6), so that the (1) and (6) need to be removed and wall distributing ribs are generated at the positions of the control points, wherein the graphic element closest to the break line in (1) is a (2) lacing wire, so that hoops need to be generated at the positions of the control point of (2) and the two control points of (1) closest to the break line; similarly, the primitive closest to the break line in (6) is the lacing wire in (5), so hoops need to be generated at the control point of (5) and the control point of (6) closest to the break line, and the hoops are formed as shown in fig. 10.
