what‘s the function of LDToggleDim()？？？

Hi,

You can try (whereIs LDToggleDim) to check if a function is built-in or custom. It should even give you the source file of the function (if loaded in debug mode).

Here is a solution to find the source of functions which works most of the time : 

1. Do your usual project setup but stop just before starting virtuoso.
2. Instead of running Virtuoso as usual, run virtuoso -nocdsinit

If you are usually running a wrapper provided by your CAD, the following should do (before running the wrapper) :
- csh: alias virtuoso \virtuoso -nocdsinit \!*
- bash: virtuoso() { \virtuoso -nocdsinit $* ;}
- otherwise, you can always create <any_dir>/bin/virtuoso as a wrapper which will run the second virtuoso executable available from path and add <any_dir>/bin/virtuoso to the beginning of $PATH.

3. Once your Virtuoso without customization is running, paste the following in the CIW :

   (sstatus debugMode t)
   (sstatus keepSrcInfo t)
   ;; The following should work out-of-the-box
   ;; Otherwise, replace `ddGetStartup` call by the hardcoded .cdsinit path
   (load (ddGetStartup ".cdsinit")) 

4. Once this is done, this SKILL command should give you the source file : (whereIs LDToggleDim)

This might not work in all cases, for instance if loading the .cdsinit changes the sstatus switches.
(This is often done by CAD as debugMode uses more licences)

Hope this helps,
Aurel

Actually, turning on the debugMode switch does not need more licenses. BTW, keepSrcInfo is usually on (I've never seen anyone turn it off, but probably a good belt-and-braces approach to ensure it's on). What checks out the SKILL Development license is using any of the debugger/IDE features or SKILL functions.

Other than that, this is a great suggestion (I should have made it myself, as it's what I do to track down such functions!)
