Description

Technical Field

[0001] The present invention relates to the technical field of AutoCAD drawing, in particular to a parameterized drawing frame construction method for AutoCAD. Background Art

[0002] As the graphics support software for system development, AutoCAD has powerful two-dimensional drawing functions, a simple user interface, easy-to-learn software, and an open architecture that provides a variety of secondary development tools. It has a wide user base in the field of two-dimensional drawing.

[0003] However, for AutoCAD beginners and people who do not use it frequently, they are still required to have certain drawing skills and some in-depth understanding of the functions of AutoCAD software itself in order to use the software for simple design work. However, for some non-standard drawing frame forms and complex drawing requirements, the drawing frame templates that come with AutoCAD software cannot meet the design requirements. Summary of the Invention

[0004] The technical problem to be solved by the present invention is: in order to overcome the deficiencies in the prior art, the present invention provides a parametric drawing frame construction method for AutoCAD.

[0005] The technical solution adopted by the present invention to solve the technical problem is: a parametric drawing frame construction method for AutoCAD, comprising the following steps:

[0006] S1: Extract the parameters contained in the drawing to be drawn and give the drawing frame standard according to the parameters;

[0007] S2: Customize the drawing frame template according to the parameters and drawing frame standards, and store the drawing frame template in the AutoCAD template library;

[0008] S3: Through the block function of AutoCAD, call the frame template in the template library, edit the frame template in the AutoCAD drawing interface, store attribute XData and dictionary in the block, record attribute text and signature box, and support dynamic attribute text collection and acquisition, batch modification of text and information docking or collaboration with the management system.

[0009] Specifically, the frame standard includes the name, specification, font, font size, position and size of each parameter.

[0010] Furthermore, the frame template includes a PDF file signing service. Through the extensible keywords of PDF, the frame properties and signature frame information are stored. The exported PDF file contains all the information of the frame, providing support for rapid retrieval and role signature in the subsequent management system; and the exported PDF file supports password encryption or certificate encryption.

[0011] Furthermore, the frame template includes a DWF signature service. By storing the frame attributes and signature frame information in the DWF metadata node Global EPlot, the exported DWF file contains all the frame information, providing support for rapid retrieval and role signatures in the subsequent management system; the exported DWF file supports password encryption.

[0012] Furthermore, the differences between the same drawing at different design stages can be compared: through the handle's quick built-in index, if the handle units in the index do not correspond, the differences are directly marked in red; for the same handle units in the index, the feature categories and feature points are identified, and the differences are determined by the feature categories and feature points, and the differences are marked in red.

[0013] Furthermore, step S1 also includes the following steps: using the Edit Shared Parameters command in AutoCAD to create a shared parameter file for the extracted parameters of the drawing to be drawn, defining the path and file name of the shared parameter file, and saving the generated shared parameter file.

[0014] Furthermore, the frame template also includes the incorporation of frames of different frame ratios. First, the main ratio is determined, and the frame is drawn on the plan of the main ratio; then the node details are determined, and the frame is drawn according to the node details. Finally, the frame of the node details is copied to the frame of the main ratio to complete the frame incorporation.

[0015] The beneficial effects of the present invention are as follows: the present invention provides a parametric drawing frame construction method for AutoCAD, which can flexibly modify the drawing frame as needed through the construction of the parametric drawing frame, greatly improving the efficiency of drawing and reducing the difficulty of drawing. DETAILED DESCRIPTION

[0016] The present invention will now be described in detail.

[0017] A parametric drawing frame construction method for AutoCAD of the present invention comprises the following steps:

[0018] S1: Extract the parameters of the drawing to be drawn and generate drawing frame standards based on the parameters. The Edit Shared Parameters command in AutoCAD is used to create a shared parameter file for the extracted drawing parameters. The path and file name of the shared parameter file are defined and saved. The drawing frame standards include the name, specification, font, font size, and drawing frame location and size of each parameter.

[0019] S2: Customize the drawing frame template according to the parameters and drawing frame standards, and store the drawing frame template in the AutoCAD template library;

[0020] S3: Through the block function of AutoCAD, call the frame template in the template library, edit the frame template in the AutoCAD drawing interface, store attribute XData and dictionary in the block, record attribute text and signature box, and support dynamic attribute text collection and acquisition, batch modification of text and information docking / collaboration with the management system.

[0021] Furthermore, the frame template includes a PDF file signing service. Through the extensible keywords of PDF, the frame properties and signature frame information are stored. The exported PDF file contains all the information of the frame, providing support for rapid retrieval and role signature in the subsequent management system; and the exported PDF file supports password encryption or certificate encryption.

[0022] Furthermore, the frame template includes a DWF signature service. By storing the frame attributes and signature frame information in the DWF metadata node Global EPlot, the exported DWF file contains all the frame information, providing support for rapid retrieval and role signatures in the subsequent management system; the exported DWF file supports password encryption.

[0023] Furthermore, the differences between the same drawing at different design stages can be compared: through the handle's quick built-in index, if the handle units in the index do not correspond, the differences are directly marked in red; for the same handle units in the index, the feature categories and feature points are identified, and the differences are determined by the feature categories and feature points, and the differences are marked in red.

[0024] When adjusting the scale of a drawing, for example, you want to put a 1:20 node template in a 1:100 floor plan. First, determine that 1:100 is the main scale of the drawing. The 1:100 floor plan is drawn according to the above method. The 1:20 node template is also drawn according to the above method, and the various settings are modified. When you find that it is necessary to incorporate it into the 1:100 drawing, copy the 1:20 node into the 1:100 drawing frame, scale it 5 times, and then you need to modify the two parameters in the linear scale and annotation. The first is to change the global scale of the annotation to 1:100 (that is, the main scale), and the second is to change the linear scale of the annotation to 0.2. Of course, when drawing drawings of other scales, if you determine from the beginning that it will be placed together with drawings of other different scales, some of the above orders can be adjusted, which can reduce some steps and improve some efficiency.

[0025] With the above-described preferred embodiments of the present invention as inspiration, and with reference to the above description, relevant personnel may make various changes and modifications without departing from the scope of the present invention. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
