Creation of blocks in PID

Thread Content

1. Select the lines that need to be combined into a block, then use the “Make Block” command.
2. Use the UCS/O command to set one point of the block as the (0,0,0) coordinate.
3. Place the block on layer 0.
4. Use the command “-w” (e.g., filename####).
5. Open ####, insert the attribute definitions for the block, and edit the default values and display values as needed. (Pay attention to the text of the attribute definitions and the position of the block; usually, the “m/ins” command is used to adjust these.)
6. Use the command “-w” again; the filename remains ####, replacing the previous one. When selecting objects, the text will appear first, followed by the block.
7. Close the file without saving it.
8. Create a new DWG file, use the “Insert/Block” command, select ####, and insert it.
9. Place the desired block on the appropriate layer.
10. You can double-click on the attribute block to edit its text.
11. In PID files, it’s common to create tables for analysis. With such attribute blocks, all attributes can be extracted into a CSV file using the extraction function (which can be opened in Excel). For even more convenience, you can create a menu based on the instructions provided in the CAD version. http://bbs.hcbbs.com/thread-76624-1-3.html This is the process of creating the blocks I use for implementing PID control; it should be very useful for those who work with PID control. Even for those who don’t use PID, applying such techniques in practical applications can save time and effort. This post was last edited by salinayuanliang on 2008-1-8 at 13:44
