Temporarily change the running object snap mode

Stores the Object Snaps you have running at Run-Time and resets the Object Snap mode to specific settings. Once the code is run again, the original settings are restored. 


At my job, I design pools. And when I dimension the pool I like to use the Center object snap and everything else off. I usually have a lot more snaps running than just Center, so it becomes tedious to keep checking on/off the same check boxes everytime I dimension a pool. So I made this code as sort of a "switch" for when I dimension pools, specifically. But you can set it to whatever you prefer, just follow the code. 


instructions for use

How to use:

  1. Open the VBE (Alt+F11)
  2. Insert a new module (or use an existing if you prefer) Insert --> Module
  3. Copy and Paste code into the new module (be sure no duplicates of "Option Explicit" exist)
  4. Change the Snap Settings in the code to your needs
  5. Save the project
  6. Close the VBE
  7. OR
  8. If you are going to download the attachment, then do the following:
  9. Download file
  10. Extract the file to any destination (Desktop, My Documents, etc)
  11. In AutoCAD, type VBALOAD
  12. Select the file you extracted, press enter

Test the code:

  1. In AutoCAD, choose Tools --> Macro --> Macros... (or Alt+F8) and choose "Change_Snaps" to change the Object Snap setting to the desired settings
  2. Repeat step 1 to restore the previous snap settings
  3. If you like, create a user defined button and in the Button Properties under "Macro Associated with this Button" paste the following (without quotes): "-vbarun Change_Snaps"
