The MillEditPost.exe should be in the root of the V23 installation... But it is not recommended for V24.. Your best bet, since you already started out this way, is to use a text editer like Notepad.
We should just figure out why your edits arent posting the changes you made..
Be sure that the post you are editing is the actual one you are posting with. To do this, make your edits and csave them with notepad, then when in your BobCad file, right click the selected post and choose edit, then navigate to and choose the one you just edited and post. Note: BobCad will retain the selected post within it's file and post with that, or the default the first time through.. In other words, if I have a post named "Burr" and you open my file and just select post code, it will post with a default post because there is no Burr post in your folder) So reselecting after editing may be nessasary.
With some of the newer OS's and UAC enabled, you cant save a post you are editing to the BobCad post folder with notepad. You will have to save it to somewhere else, then copy it back into the post folder to overwrite what is there..(The only way around this is to start notepad first, as Administrator, then open and edit the post... You can create a shortcut that will launch notepad with admin rights for this)
The Variables selection comes from a text file called "PostVariables.txt" in the posts folder. You can just open this file to read the variables and desciption to use in your editing..
If you really want the editer as a learning tool, you can find it here:
