Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the present application will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
In order to facilitate understanding of the present embodiment, technical terms designed by the present application will be briefly described below.
"Block" is a drawing term that refers to the combination of commonly used pipe and part graphics into a whole, and the common operations of quickly adding part blocks to a drawing by inserting blocks during the subsequent drawing process mainly include: creation of block definitions, insertion of block references, cleaning of blocks.
The created blocks can also be divided into two types, a normal block and a nested block according to the habit of the plotter. The common block is formed by adding necessary basic primitives from blank to each block definition created. The common blocks are relatively independent, and no nesting and dependency relationship exists. The cleaning of a common block is relatively simple, and all block references defined based on the block need only be deleted in the drawing, and then cleaned in a "clean" dialog box. By nested block, it is meant that when a block is created, the contents of that block are not just the base primitive, but also include other blocks, which already form "there are blocks in the block".
After technical terms related to the application are introduced, application scenes and design ideas of the embodiment of the application are briefly introduced.
The cleaning of the nested blocks needs to clean all block references in the drawing and then clean the block definitions used as the block references, and meanwhile, the nested blocks are required to be ensured not to be nested by other blocks, while one drawing in the prior art often comprises a great deal of contents, the nested relation of the blocks is complicated, the relation among the nested blocks or the block definitions cannot be clearly displayed, and the blocks existing in the drawing cannot be cleaned, so that the block cleaning operation cannot be smoothly performed.
Based on the above, the embodiment of the application provides a method and a device for cleaning a block of a CAD, an electronic device and a storage medium, wherein the method for cleaning the block of the CAD is applied to a CAD tool, the CAD tool comprises a memory and a processor, the memory stores a computer program, and the processor executes the computer program to realize the method for cleaning the block of the CAD provided by the embodiment of the application.
Example 1
The embodiment provides a block cleaning method of CAD, which is applied to CAD tools loaded with drawing files and block definition cleaning plug-ins. Referring to fig. 1, the method provided in this embodiment includes the following steps:
s110, the processor responds to the opening operation for the target drawing file and displays a CAD image corresponding to the target drawing file; the CAD image is loaded with block references.
S120, the processor responds to the deleting operation for the target block reference to delete the target block reference in the CAD image.
S130, the processor responds to the starting operation of the block definition cleaning plug-in and the block definition cleaning auxiliary triggering operation to generate and display a block definition tree diagram corresponding to the CAD image; the block definition tree diagram comprises a root node block definition and a child node block definition under the root node block.
S140, the processor responds to the deleting operation defined by the target node block based on the block definition tree diagram.
In this embodiment, when a user opens a block definition cleaning plug-in and triggers a block cleaning operation, a block definition tree diagram corresponding to a CAD image is generated and displayed, where the block definition tree diagram includes a root node block and a child node block under the root node block, and the block definition tree diagram is used to display a nesting relationship between the block definitions, so that the user can know the nesting relationship between the blocks, so that the user can thoroughly understand the blocks in a complex drawing file.
In the engineering drawing process, the CAD image contains thousands of part patterns, when the image block formed by simple lines is reused, the original image block needs to be copied to a designated position, and the lines are easy to miss or select in the copying process, so that the error rate is high. In order to reduce the error rate and improve the drawing convenience and drawing efficiency, a block formed by certain lines is generally created as a block definition, so that the block is defined as a whole, and the operation of reinserting the whole block for use or copy pasting is performed, so that the drawing efficiency is greatly improved.
However, when a drawing engineer wants to delete a block definition in the face of drawings drawn by others or drawings with a lot of block definitions, because there may be a nesting relationship between each block definition, the block definition to be cleaned cannot be cleaned when being referred to by other block definitions, and when the block definition cleaning plug-in this embodiment is started and triggers a block cleaning auxiliary operation, a block definition tree diagram corresponding to a CAD image is generated and displayed, so that the nesting relationship between each block definition is clear, and the block definition cleaning work is facilitated to be smoothly performed.
With reference to the first aspect, step S120 includes the steps of generating and displaying a block definition tree diagram corresponding to the CAD image, where the step includes:
the blocks in the traversal target drawing file refer to the corresponding block definitions.
For each block definition, it is determined whether other block definitions are included in the block definition.
If so, traversing the child node marking the block definition as the other block definition.
If not, marking the block definition as a root node.
Based on the root node and the child nodes, a block definition tree graph is generated.
Firstly, traversing block references in a target drawing file, acquiring block definitions corresponding to the block references, and then defining whether recursive traversal contains other block definitions for each block, thereby forming a block definition tree diagram.
For example, the block references present in the target drawing file are: valve, stop valve, ball valve, manual control ball valve (as shown in figure 2), wherein the stop valve block definition is a block definition added with straight line preservation on the basis of the valve block definition; the ball valve block definition is a block definition stored after a circle is added on the basis of the valve block definition; the manual control ball valve block definition is a block definition stored after adding a straight line on the basis of the ball valve block definition.
Traversing block definition in a drawing by adopting the following codes and constructing a block definition tree diagram:
private static void GetAllBlocks()
{
foreach (ZWCAD.ZcadBlock B in doc.Blocks)
{
if (!B.IsLayout)
{
Console.WriteLine(B.Name);
LoopBlock (B); and/or recursive traversal
}
}
}。
Specifically, the block definition in the drawing is traversed and the name of the block definition is printed: valve, stop valve, ball valve, manual control ball valve;
then, the block definitions are traversed in turn, for example, the valve block definition is traversed first, and the traversing result is that the valve block definition does not contain other block definitions and is referenced by other block definitions, and then the valve block definition is a root node relative to itself and is a child node of the other three block definitions.
Then traversing the second block definition-stop valve block definition, wherein the traversing result is as follows: the stop valve block definition includes the valve block definition and is not included by other block definitions, at this time, the stop valve is a child node under the valve block definition, and the valve is a root node.
The same method traverses ball valve block definition, and the traversing result is as follows: the ball valve block is defined as a sub-node defined by the valve block, and the root node is a valve.
The same method traverses the definition of the manual control ball valve block, and the traversing result is as follows: the manual control ball valve is a sub-node defined by a ball valve block, and the ball valve block definition also comprises a valve block definition, at the moment, the valve is a root node, a sub-node named as a ball valve is arranged below the root node, and a sub-node named as a manual control ball valve is arranged below the ball valve sub-node.
By generating and displaying the tree diagram of the block definitions, the nesting relation among the block definitions is clear at a glance, and the cleaning of engineers on the block definitions is facilitated.
With reference to the first aspect, the step of defining a tree graph based on blocks, in response to a deletion operation defined by a target node block, includes:
responding to selected operation and deleting operation aiming at the definition of the target node block in the block definition tree diagram, and acquiring the node type corresponding to the definition of the target node block;
and executing corresponding deleting operation according to the node type defined by the target node block.
With reference to the first aspect, the CAD tool further includes a block definition list for storing block definitions; the step of executing the corresponding deletion operation according to the node type defined by the target node block includes:
and if the node type of the target node block definition is a child node, deleting the target node block definition and updating the block definition list.
If the node type of the target node block definition is the root node, judging whether a child node block definition exists under the target node block definition, if so, displaying prompt information that the target node block definition has references and cannot be deleted; if not, deleting the block definition corresponding to the target node block definition and updating the block definition list.
In short, a target node block definition to be cleaned can be cleaned only if the target node block definition is not contained by other block definitions.
When a target node block definition in a tree diagram is selected and deleting operation is executed, firstly acquiring a node type corresponding to the target node block definition, and when the node type of the target node block definition is a child node, indicating that the target node block is not referenced by other block definitions, wherein the block definition can be deleted directly; when the node type of the target node block is a root node, judging whether a sub node block exists under the target node block, namely judging whether other block definitions comprise the target node block definition, if not, indicating that the sub node block does not exist under the target node block definition, and cleaning the target node block definition at the moment so as to thoroughly delete the block definition in a drawing file; if yes, the target node block definition is referenced and nested by other block definitions, the target node block cannot be deleted at the moment, and prompt information that the target node block cannot be deleted is provided.
In combination with the first aspect, the step of defining a tree graph based on the blocks, and responding to the deletion operation defined by the target node block includes:
responding to the touch operation of the second designated key, and displaying a cleanable item list corresponding to the CAD image in the block definition cleaning plug-in;
marking the target block definition as a selected state in response to a selection operation for the target block definition;
and deleting the target block definition in response to the touch operation for the third designated key.
Displaying a clearly-defined item list when an engineer touches a key to clear a target node block definition, wherein the list enumerates deletable block definitions, and deleting the target block definition in the drawing file by the processor after selecting the target block definition and determining to delete the touch operation.
In combination with the first aspect, the CAD tool further comprises a block editor, the method further comprising:
one or more block references are added at the block editing interface in response to a touch operation for the block editor.
For each block reference, responding to attribute triggering operation for the block reference, and displaying a corresponding attribute editing interface of the block reference; the property editing interface is provided with style editing options.
In response to an editing operation or a selection operation for a style editing option, the adjustment block refers to the corresponding attribute.
In response to a save operation for a block reference, the block reference is stored in a block definition list and the block definition is displayed in the block definition list.
The block definitions may be edited by a block editor to facilitate the cartographic process.
In combination with the first aspect, the block definition cleaning assistance triggering operation includes a touch operation on a first designated key or a touch operation on a designated control.
In this embodiment, the quick cleaning auxiliary tool may be started by touching a designated key or touching a designated control, where the designated key may be predefined for a user, for example, the designated key is set to be F5, and touching the F5 key may trigger the block to define the cleaning auxiliary tool; the touch control designating control is also preset and constructed, such as "blockPurge. Exe" software.
Now, for example, in response to an open operation for a "nested block-valve-dwg" target drawing file, a CAD image corresponding to "nested block-valve-dwg" is displayed;
the 'nested block-valve-dwg' drawing file comprises four block definitions of a valve, a stop valve, a ball valve and a manual control ball valve, and the nested relation among the block definitions is shown in figure 2; and touching a first designated key such as F5 to trigger a block definition cleaning auxiliary tool and starting a block definition cleaning plug-in, and generating and displaying a block definition tree diagram corresponding to the nested block-valve dwg drawing, wherein the interface schematic diagram is shown in figure 3.
Based on the block definition tree diagram, four root nodes from top to bottom are all 'valves', and a child node block does not exist under the first root node; the child node block existing under the second root node is a 'stop valve'; the child node block under the third root node is a ball valve; the sub-node blocks existing under the fourth root node are ball valves which are used as block references of manual control ball valves, namely the manual control ball valve sub-nodes exist under the ball valve sub-nodes.
At this time, the deleting operation of the corresponding target node block definition judges the node type defined by the target node block, for example, in this embodiment, the target node block is "valve", and it is judged that the sub-node with which the "valve" is referred to as a block exists, and at this time, a prompt message that the "valve" is referred to by another block and cannot be cleared is displayed. In this case, the "valve" needs to be deleted after deleting the block definitions corresponding to all the child nodes. That is, it is necessary to delete all of the block definitions named "manual control ball valve", "stop valve", and then confirm that no child node exists under the "valve" block definition to delete the "valve" definition.
The specific operation is as follows: judging whether a child node exists under the definition of the target node block based on a block definition tree diagram, if not, deleting the block reference corresponding to the definition of the target node block in the drawing, triggering the touch operation (such as 'Delete') of a second designated key to display a cleanable item list corresponding to the CAD image in the block definition cleaning plug-in, selecting the definition of the target node block, confirming, deleting the definition of the target node block, and thoroughly cleaning the definition of the target node block at the moment.
If the sub node exists under the target node block definition, deleting the block reference corresponding to the sub node block definition under the target node block definition in the drawing, triggering the touch operation (such as 'Delete') of the second designated key to display the cleanable item list corresponding to the CAD image in the block definition cleaning plug-in, selecting the sub node block definition and confirming, deleting the sub node block definition until the sub node does not exist under the target node block definition, and repeating the steps at the moment to Delete the target node block definition.
In a second aspect, the present embodiment provides a block cleaning device for CAD, which is applied to a CAD tool, where the CAD tool is loaded with a drawing file and a block definition cleaning plug-in. Referring to fig. 4, the apparatus includes: the image display module 10, the target block reference deletion module 20, the tree diagram generation display module 30, and the deletion module 40.
The image display module 10 is configured to display a CAD image corresponding to a target drawing document in response to an opening operation for the target drawing document.
The target block reference deleting module 20 is used for deleting target block references in CAD images in response to deleting operations for target references
