[0050] <Method Example>
[0051] The present disclosure provides a dimensioning method, which can be implemented by an electronic device.
[0052] Figure 2 Flowchart of a dimensioning method according to an embodiment of the present disclosure.
[0053] like Figure 2 As shown, the method includes steps S2100 to S2300 as shown below:
[0054] Step S2100: Obtain a three-dimensional drawing of the target object.
[0055] In this embodiment, the target object may be a part used to constitute a product, or may be a product. The three-dimensional drawing of the target object may be a three-dimensional part drawing file for designing the target object.
[0056] Step S2200: identifying target features to be dimensioned in a three-dimensional drawing, and obtaining the dimensions of the target features.
[0057] In this embodiment, the target features can be set in advance according to the type of the part in the three-dimensional drawing. For example, the target features can include at least one or more of the following: contour, hanging platform, hole, slot, etc.
[0058] Furthermore, the size of the target feature may be obtained based on a size requirement of the target feature, wherein the size requirement of the target feature may be, for example, a linear size, an angular size, or a radial size.
[0059] In one embodiment of the present disclosure, before obtaining the size of the target feature, the method may further include: straightening the target object according to a processing view of the target object; and constructing a spatial rectangular coordinate system with the target point of the target object as the origin.
[0060] On this basis, the size of the target feature is obtained, including: obtaining the size of the target feature according to the position of the target feature in the spatial rectangular coordinate system.
[0061] In this embodiment, the target point may be the center of the target object or any point on the target object, which is not limited here.
[0062] This embodiment constructs a spatial rectangular coordinate system to obtain the position of each point in the target object in the spatial rectangular coordinate system, thereby facilitating obtaining the size of the target object based on the position of each point in the target object in the spatial rectangular coordinate system.
[0063] Step S2300: Mark the target feature according to its size.
[0064] In this embodiment, the target feature may be dimensioned according to the size requirement of the target feature.
[0065] Specifically, if the target feature's dimension requirement is a linear dimension, the target object's dimension may be a length. In this case, marking the target feature's dimension is equivalent to marking the target feature's length. If the target feature's dimension requirement is an angular dimension, the target object's dimension may be an angle. In this case, marking the target feature's dimension is equivalent to marking the target feature's angle. If the target feature's dimension requirement is a radial dimension, the target object's dimension may be a diameter or radius. In this case, marking the target feature's dimension is equivalent to marking the target feature's diameter or radius.
[0066] Through the embodiments of the present disclosure, target features to be dimensioned in a three-dimensional drawing of a target object are identified, and the dimensions of the target features are obtained. The target features are then automatically dimensioned based on the dimensions of the target features without the need for manual dimensioning. This can reduce human dimensioning errors, improve the accuracy and consistency of dimensioning results, and improve the dimensioning efficiency of drawings.
[0067] In addition, if the design structure of the target object changes, the method of this embodiment can re-dimension the object according to the updated three-dimensional drawing, thereby achieving adaptive updating of the dimensioning results.
[0068] In one embodiment of the present disclosure, marking the target feature according to the size of the target feature may include: marking the target feature in a three-dimensional drawing according to the size of the target feature.
[0069] In this embodiment, the target features may be dimensioned in the three-dimensional drawing using a product and manufacturing information (PMI) annotation method.
[0070] Through this embodiment, a dimensioned three-dimensional drawing can be obtained.
[0071] In another embodiment of the present disclosure, marking the target feature according to its size may include: obtaining a two-dimensional drawing of the target object according to the three-dimensional drawing; and marking the target feature in the two-dimensional drawing according to its size.
[0072] In this embodiment, the dimensioning method of the drawing module may be used to dimension the target features in the two-dimensional drawing.
[0073] In this embodiment, the two-dimensional drawing of the target object may include at least one basic view of the target object, and the basic view may include a front view, a top view, a left view, a right view, a bottom view, and a rear view.
[0074] Through this embodiment, a dimensioned two-dimensional drawing can be obtained.
[0075] In one embodiment of the present disclosure, the method may further include: compressing and converting the annotated drawing into a drawing file of a set format for storage.
[0076] In this embodiment, the set format can be pre-set according to the annotation scenario. In an embodiment of dimensioning target features in a three-dimensional drawing, the set format can be JT format or GLB format. In an embodiment of dimensioning target features in a two-dimensional drawing, the set format can be PDF format.
[0077] This embodiment compresses and converts the annotated drawings to a lightweight file format that is only 1 / 30 the size of the original format, or even smaller, while preserving the essential information of the 3D model and ensuring the necessary accuracy. This lightweight file format facilitates the rapid transmission of the drawing file over the network and allows for convenient interactive operations such as viewing and annotating the 3D model of the target object using common browser software or other tools. This, combined with Model-Based Design (MBD) technology, enables paperless manufacturing and the upgrading of intelligent manufacturing models.
[0078] In one embodiment of the present disclosure, the method may further include: displaying the annotated drawing or the drawing file in a set format.
[0079] In one embodiment of the present disclosure, the method may further include: acquiring tolerance information of the target feature; and marking the target feature according to the tolerance information.
[0080] In one embodiment of the present disclosure, the tolerance information of the target feature may be pre-set by a designer and stored in a three-dimensional drawing.
[0081] In another embodiment of the present disclosure, the tolerance information may be represented by color. Then, obtaining the tolerance information of the target feature includes: obtaining color information of the target feature; and obtaining the tolerance information of the target feature according to the color information of the target feature.
[0082] In this embodiment, a comparison table reflecting the correspondence between color and tolerance can be pre-set. By searching the comparison table according to the color information of the target feature, the tolerance information corresponding to the color information of the target feature can be obtained, that is, the tolerance information of the target feature.
[0083] When the tolerance information of the target feature is obtained, the target feature can be marked according to the size and tolerance information of the target feature. For example, if the size of the target feature is 97 mm and the tolerance information of the target feature is 1 mm, then the result of marking the target feature according to the size and tolerance information of the target feature can be 97 ± 1 mm.
[0084] Through this embodiment, the structure, size, and tolerance information of the target object can be integrated together, so that designers, process personnel, manufacturing personnel, etc. can share the same annotation data, reducing errors and delays in information transmission.

[0086] like Figure 3 As shown, the dimensioning method may include:
[0087] Step S3001: Obtain a three-dimensional drawing of the target object.
[0088] Step S3002 : straighten the target object according to the processing view of the target object, and construct a spatial rectangular coordinate system with the target point of the target object as the origin.
[0089] Step S3003 , identifying the target feature to be dimensioned in the three-dimensional drawing, and obtaining the size of the target feature according to the position of the target feature in the spatial rectangular coordinate system.
[0090] Step S3004: Obtain tolerance information of the target feature.
[0091] Step S3005: Mark the target feature according to its size and tolerance information.
[0092] Step S3006: compress and convert the annotated drawing into a drawing file of a set format for storage.
