Block Editing (BEDIT)
If we just need to edit the graphics of the block, the operation of block editing is very simple. A large number of parameters and action settings are provided in the block editing. Complex actions can be set for the blocks, the blocks can be parameterized, multiple graphics can be merged into one block, and one block can also be transformed into multiple blocks. The block editor is very complicated. Here I will briefly introduce the operation to you.
1. Create a block or open a drawing with blocks, double-click an ordinary block without attribute text, and the software will pop up a block editing dialog box.
2. We can also enter the BEDIT command directly or click the block edit button in the command panel to open the dialog box first, and then select the block we want to edit in the list.
After confirming from the preview and name that it is the block we want to edit, click the "OK" button to enter the block editor.
3. After entering the block editor, only the graphics of the block will be displayed in the graphics window, and the panel and option board of the block editor will also be displayed. If the classic interface is used, quick editing related information will be displayed. Toolbar.
We can see that the quick editor has a large number of tools. If you want to introduce them in detail, you can write a book. I will not introduce them in detail here. I will introduce them separately later. Let’s just look at the tools for modifying graphics. Basic operations.
In the block editor state, we can use drawing and modification commands to add, edit, and delete graphics. When the graphics are modified, click the "Close Block Editor" button, as shown in the figure below. Show.
4. The software will prompt whether to save the modifications to the block. Select to save the modifications to the block and exit the block editor.
5. After exiting block editing, the graphics will resume display.
Reference editing (REFEDIT)
The reference editing function is a function of editing blocks that was widely used before block editing. Before there was a block editor, double-clicking a block would enter reference editing. Function. The reference editing function can not only edit blocks, but also edit external references (XREF). The current version will automatically execute the reference editing function when double-clicking the external reference.
The reference editing function allows you to select any block reference after the block is inserted, and modify the block definition by editing this reference. The difference between reference editing and block editing is that when entering the reference editing state, other graphics can still be displayed. We can add other graphics to the block or separate the graphics in the block.
Because you can see other graphics during reference editing, but not block editing, and most people do not define dynamic blocks, many designers still like to use reference editing when editing blocks, and like Change the default command executed by double-clicking a block to reference editing. Below we briefly introduce the operation of reference editing.
1. Create a block or open a drawing with blocks, select the block, enter the command REFEDIT and press Enter, or select the reference editing command in the menu or toolbar, press Enter, and open reference editing. dialog box. As shown below.
2. If we select just a simple tile, only the name of the current tile will be displayed in the list. We note that there are two options for nested tiles below. The so-called nested tiles mean that a tile contains other tiles. For example, a table and a chair are two independent tiles. We can combine a table with When making a table and chair tile with four chairs, it becomes a nested tile. If you select a nested tile, a list will be displayed here, and all the tiles at the next level will be listed. We can choose to edit the entire tile or select one of the nested tiles for editing.
In addition, this dialog box also has a settings tab, which has three options. You can take a look at it first. The main one is the last one "Lock objects not in the working set" which will have some impact on editing. The so-called "not working" Sets, that is, other shapes other than tiles.
We use the default options, click OK, close the reference editing dialog box, and enter the reference editing state, as shown in the figure below.
3. The reference editing panel will be displayed in the command panel. If you use the classic interface, the reference editing toolbar will pop up. After entering the reference editing state, the graphics in the block will be displayed normally, and other graphics will be faded and displayed, so that the internal and external graphics can be distinguished.
We note that there are two buttons in the toolbar, one is to add to the working set, and the other is to delete from the working set. This is a function that cannot be achieved by block editing.
3. After trying the above two editing functions and other drawing and editing commands, click the Save Changes or Abandon Changes button to exit the reference editing function.
Remember that you must exit the reference editing function after reference editing. At that time, many people used the classic interface. After reference editing the block, they directly turned off the reference editing toolbar without exiting the reference editing function. It turns out that the drawing cannot be saved, and the following prompt will pop up every time it is saved.
4. Since the reference editing toolbar is closed and I don’t know the command to close reference editing, I don’t know what to do. Now that fewer people use reference editing, this problem is less prominent, but it is also best to remember that the command to close reference editing is REFCLOSE. If you encounter it, you will know how to solve it.
Reference cropping (XCLIP)
1. The XCLIP command can not only crop blocks, but also crop external references. It can not only crop blocks outside the closed area, but also reverse them. Crops the graphics within the enclosed area. Some designers will make complex graphics into blocks, and then take part of the block at different times. At this time, they can use XCLIP to crop. This operation is not complicated. You can draw and edit it when cropping, or you can draw a closed polyline and select this polyline when cropping. I will not introduce it in detail here and will introduce it separately later.
Enhanced attribute editor
If there is attribute text in the block, it is called an attribute block. When you double-click such a block, the block editor or reference editing will not pop up, but The Enhanced Property Editor will pop up because this type of tile usually modifies properties rather than graphics, as shown in the image below.
Summary
1. The above is just a brief introduction to the commands related to tile editing. Each command is not explained in detail. It is just to give you a preliminary understanding. If you want to know more For the usage of these commands, please pay attention to the relevant experience posted later.
