Evening everyone, 

New member and first time poster here so apologies if this is in the wrong section.

Im currently building a producing instructions for a model and have use a buffer exchange command to show the placement of a tile in the main build. 

Now Ive followed the information from Holly-wood.it and the working with pub google site but I still have an issue.

The 'hovering' part appears with the arrow in the correct location but on the next step it recounts the piece in the PLI so you end up with a extra piece. Is it something simple that I've missed or arranged incorrectly ? The code looks correct but Im not sure.

Here is the code:

Johann,

Awesome! That worked perfectly thanks! I had been trying to get it working for over a day  Confused 

So how does the extra line of code work if you don't mind me asking ? Does it just tell Lpub to ignore that part ?

Again Thanks!

Again Thanks!

Hi Tom

Yes.
All parts between "!LPUB PART BEGIN IGN" and "!LPUB PART END" are ignored.
So it is very important not to forget the "! LPUB PART END", otherwise all parts will be ignored immediately.

Regards Johann

The reason the tutorial doesn't mention this is that the old LPub (non 3d) automatically ignored parts after buffer exchange. Or something like that, can't remember it very well.

Ah ok thanks! Was getting proper annoyed with it as the code and everything matched the tutorial, but it wasn't working! Now that explains why !

Correct. Earlier versions (like you describe non 3D) did this indeed. Though not always flawless.
