FIG. 1 is a flow chart of a house type drawing method for drawing a door and window opening by one-step dragging according to the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
As shown in fig. 1, the house type drawing method for drawing a door and window opening by one-step dragging of the invention comprises the following steps:
s101, creating a temporary mesh and a two-dimensional coordinate system for displaying the shape and the door and window hole identification during drawing;
s102, selecting a target wall in the CAD user type graph, obtaining width data of the target wall, setting a drawing point on a side wall line of the target wall, recording the starting position of the drawing point, and recording as start (X0, Y0);
s103, dragging a drawing point in the extending direction of the door and window opening, enabling the drawing point to adsorb the other edge of the target wall in the dragging process, calculating the extending width of the drawing point from one wall line of the target wall to the other wall line by using a distance formula between the two points, and marking as width;
s104, adjusting the drawing length of the drawing point along the target wall, calculating the drawing length of the drawing point along the target wall by using a distance formula between two points, recording the drawing length, finishing drawing when the drawing is finished, and recording the end position of the drawing point as end (X1, Y1);
s105, matching the width of the target wall with the extension width of the drawing point, and judging that the drawing type is a common door or window if the extension width is as wide as the width of the target wall; if the width is smaller than the wall width, the wall is a hole; if the width of the window is larger than the wall width, the window is a bay window;
s106, storing the drawn door and window hole parameters into the Profile _ PPM.
The data of the target wall includes a start position startpoint, an end position endpoint, a wall left width leftwidth and a wall right width of the target wall. The sum of the left wall width and the right wall width is the width of the target wall. The data of the target wall is already produced in the CAD layout, and the data of the target wall is extracted directly from the file of the CAD layout in S102.
When drawing points are dragged, drawing lines drawn by the drawing points are straight lines. The reason for setting as the straight line is that the CAD house type graph is composed of straight lines and arc lines, and when the drawn plan graph is converted into the three-dimensional stereo graph, the wall body is closer to reality. Among them, the method of setting the drawing line as a straight line is the prior art, and is not cumbersome here.
In S103, the formula for calculating the extending width of the drawing point from one wall line of the target wall to the other wall line is: width ═ X1-X0 |. The adsorption function during drawing is driven by an adsorption pool, and when a user moves a mouse, the world space position of the mouse is compared with all point-line data to obtain an example closest to the adsorption threshold range, so that the mouse is close to the position.
In S104, the formula for calculating the length of the drawing point along the target wall is as follows: length ═ Y0-Y1 |.
S106, the door and window hole parameters comprise rotation, type, extension width, height, ground clearance height, drawing length and position; and inputting numerical value settings after the door and window hole is set. When the rotation is converted from a plane diagram to a three-dimensional diagram, the coordinate is converted into a conversion value, the height is the height of a door and window hole, and the ground clearance height is the height between the window and the hole and the ground.
In the dragging process of S103, a plurality of distance prompts appear on the operation interface for prompting the extending width and the drawing length of the door and window hole drawn in the current drawing state, and the distances from the left and right points of the door and window hole to the start position startpoint and the end position endpoint of the target wall, respectively.
And refreshing the shape of the temporary mesh according to the current door and window hole data in the dragging process of the drawing point of S103 in the S101.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
