I have just started have a problem while drawing in Cad. I can choose any layer in a drawing but once starting a drawing command ie: draw line, draw dimension, it is drawn on layer "0". I assume it is a setting somewhere, But where or what?

Thanks

I noticed this also, and it's driving me nuts. What version of Microvellum are you running? v6 or beta v65?

This is what's happening with me, while running AutoCAD 2008 with Microvellum v65 installed: Typing L (for line) into command line switches to 0 Layer. If I type L-I-N-E (no dashes), it stays on the current layer.

Our other computer here also runs AutoCAD 2008, but without the Microvellum beta upgrade - just the v6 general release . That computer does not have this problem, in that it always draws on the current layer.

I started a thread in the Autodesk discussion groups regarding this issue. No solutions as of yet, but it can be viewed here: http://discussion.autodesk.com/thread.jspa?threadID=615647

I'm suspecting that the Microvellum v65 Beta Upgrade changed some AutoCAD setting(s) that causes this, but I can't figure out what or where. Its really frustrating though.

Check out this old forum, it should cover the issue

Disclaimer on my part.  Do the following at your own risk. 

Go to your User Files and there is a file called Core C Function.lsp  (Back up the file first.)

Delete the following line in the lisp file.

;(defun c:l  () (command "layer" "s" "0" "") (command "line"))

 or put a semi-colon in the beginning like the one shown above.

I wouldn't delete it. The semi-colon in front should fix the problem.

You need to change an MV file called "Core C Functions.lsp".  It's in your "User Files" directory. 

This is the line you're looking for "(defun c:l  () (command "layer" "s" "0" "") (command "line"))".  A semicolon in front of "(defun" disables the command that puts all lines on layer 0.

Save a copy of the Core C file before you make any changes, and be sure you only have one copy called "Core C Functions.lsp" in your Microvellum directory.

Ok, so I added the semi-colon in my Core C Function.lsp, and problem is solved. Booyah!

But check this:

Switching to Layer 0 was a problem for me only once I started using v65. I checked the Core C Function.lsp on our other computer - which is running v6 - and there's no semi-colon. But it doesn't do the annoying Layer 0 change-up anyway. Huh?

What does (defun c:l  () (command "layer" "s" "0" "") (command "line")) do anyway? Why should this problem creep back up with a newer (albeit beta) version of MV? How does excusing/disabling this command differ from deleting it entirely?

I'm glad I don't have to spell out LINE anymore; thank you all for the help. But I'm curious what caused the bother in the first place.

P.S. For those of you who are running v65 with the new frameless library and want to fix this problem, remember there's now 2 UserFiles folders. I changed my Core C Function.lsp in the C:\Program Files\Microvellum\UserFiles first, and I still had this problem. You have to go to the C:\Program Files\Microvellum\Frameless Library 2007\UserFiles, (or whatever you named your library) and change the .lsp file there. That fixed it for me.

hmmm.. maybe that one computer is just specail, haha.  But everyone here is running v6 and has been since we started and I'm pretty sure we all had the same problem and had to make the change. I don't know a whole lot else about it as far as what it does and why the semi-colon instead of deleting it and such, but I do know we had to make the change.

Just a note.  I am using acad 2007 and had the same line problem. However, just adding a semicolon to the front of the line in your core C functions may completely disable your keyboard shortcut for line so instead replace the existing

 (defun c:l  () (command "layer" "s" "0" "") (command "line"))

With the following line.

(defun c:l  () (command "line"))

This only removes the layer function from the command. 

New software version, new Core C Function.lsp file.  Personally, I've had this same problem with each upgrade.

If you remove the layer function, you don't need MV to define the line command for AutoCAD.  It's already there.

Sounds like a New User Induction or something. Ha ha. Thanks again for the help. I just don't understand why that phrase is in the .lsp file if everyone just ends up turning it off or deleting it anyway. Developers, any insights?

Microvellum should just fix it. They have wasted many users valuable time with this silly problem.

Okay, Now I see I think.

I'll need to fix it.

Thanks

NOPE NOT WORKING.

We have added the ";" in front of the text string, removed the text string:"(command "layers" "s""0"")" and removed the entire line of text form the "Core C Functions .lsp file.

If we type "Line" or the line pick button it stays on the current layer.

If we type "L" to draws on layer "0"

Same thing with the arc command.

Double check you User Files Path in your options dialog box.  Make sure you changing the right file.  Restart AutoCAD.
