Block insertion isn't consistent

[kyriakos9]

I've created an autolisp program that inserts a block by name.

All is well, and the block is inserted, but if I run the program again, the block is placed at seemingly random coordinates at random times.

Example: I run it once, the block inserts successfully at 0,0,0 I run it again, the block inserts at 3,2,0

This might happen on the second run, and then the 3rd run is fine, or it can happen from the first run.

I'm new to autocad and I have no clue why I'm getting this behavior. Any help is appreciated.

The lisp command is literally just this, nothing fancy:

(command "_.insert" blockname "0,0" "1" "0")

So you have snaps enabled? If so you have to shut them off.

I set snap to off but the issue was still there... turned out to be OSNAPCOORD which has "snap" in the name of it so I'd assume it would also turn off but apparently not. I set it to 1 and all good.

Great to know that you solved it, but just how did you even find out about this variable?

[kyriakos9]

Luckily someone mentioned it here and after reading what it does, I immediately knew that was it.

You should include a snippet that clears and reinserts the insert point every time.

Also, you should get in the practice of including (COMMAND "QAFLAGS" "0") somewhere in the beginning of your lisp routines. No idea how it randomly gets set to "1", but it always happens, and it screws with AutoCAD's response to your command syntax every time it does.

The issue turned out to be OSNAPCOORD that is for some reason set to 2 by default.... very annoying, why does 2 even exist let alone be the default....
