That makes sense. I've been working on it again and now that I have my code right and am hiding the extra pieces, it is working great. Thanks, Nathan

Thank you everyone for your help. I really appreciate this. It was driving me crazy. Thanks, Nathan

Oh, I never realized that. I'll check it out. Thanks, Nathan

While you are in Edit Mode is there some setting that makes MLCAD show every single part you add to the model even if they are in a Buffer Exchange? Maybe I have to activate or deactivate some setting to make the Edit Mode only show my piece in the final position, but still show both positions in View Mode.

Ok. I did that. It still has the same problem. It has the piece in two different positions in Edit Mode. It still works in View Mode though. Is there some setting that makes MLCAD show ALL pieces even if they are in a Buffer Exchange? In the Edit Mode I mean.

Ok. First I highlighted the piece that is hovering along with the two arrows. Then I clicked 'Add Buffer Exchange'. Then I moved the store command in the Parts List Window to the very top of the screen, above all the other parts. My code now looks like this: 0 BUFEXCHG A STORE All the parts I added before I got to the piece I wanted to buffer. 0 STEP 1 0 -10 -32 0 1 0 0 0 1 0 0 0 1 30071.dat (the piece I show floating) 3 4 -10 48 0 -5 33 0 -10 38 0[ (an arrow pointing to where it should go) 4 4 -12 36 0 -12 -4 0 -8 -4 0 -8 36 0 (another arrow pointing to where it should go) 0 STEP 0 BUFEXCHG A RETRIEVE 1 0 -10 36 0 1 0 0 0 1 0 0 0 1 30071.dat (the piece where it should be) I still have the same problem. Is my code still wrong? Also I have 'Draw to Selection Only' activated. Do I need to deactivate it? Thanks, Nathan

So I have to highlight the floating piece and the two arrows pointing to where it should go before I press Add>Buffer Exchange?

What do you mean by the highlighted location?

Thank you all for replying. In view mode it does show the piece correctly. However since I want to add more pieces to the submodel, it is confusing trying to put pieces on. The piece I am using the buffer exchange for is pretty big and if I put a small piece near it, I won't even be able to see it. I have seen something called a Ghost command. Do I use that somehow? Also if all else fails, I guess I could build the whole model without the buffer exchange and then at the end just go back and add the buffer exchange in. That way I wouldn't have to try to build with the same piece in two positions. I would rather find a way to fix it though. Thanks, Nathan Thanks for replying. I can't find where to put them though. Is it possible I have the retrieve command in the wrong spot? If you look at the code I showed I was using in my earlier post, I can't find any differences between that and the one you gave me.

Thanks, NathanSorry about showing the same thing twice.

I still don't know what I'm doing wrong. I have tried moving the 'store' command to different places but I still can't make the floating part disappear and just show the final part.This is the code I am using in MLCAD. 1 0 -10 60 0 1 0 0 0 1 0 0 0 1 30071.dat (previous part-not important to what I am trying to say) 0 STEP 0 BUFEXCHG A STORE (store the screen as it looks) 1 0 -10 -32 0 1 0 0 0 1 0 0 0 1 30071.dat (the piece I show floating) 3 4 -10 48 0 -5 33 0 -10 38 0[ (an arrow pointing to where it should go) 4 4 -12 36 0 -12 -4 0 -8 -4 0 -8 36 0 (another arrow pointing to where it should go) 0 STEP 0 BUFEXCHG A RETRIEVE (retrieve the way the screen looked earlier) 1 0 -10 36 0 1 0 0 0 1 0 0 0 1 30071.dat (the piece where it should be)

I would like the ability to create submodels. That is a feature LDD lacks that it could really use. I use MLCAD and I love submodels. Also I would like them to make better building instructions. Maybe create a publisher like LPub that is compatible with LDD to make instructions(or make LDD easily compatible with LPub). Finally I think a tool to allow you to type in where a piece should go on each axis would be helpful. That would make placing pieces a lot easier. Nathan

Hi. I have been trying to use the buffer-exchange tool in MLCAD. I can't get it to work. Here are the steps I took: Added previous steps BUFFER-EXCHANGE STORE A STEP Added the piece I wanted floating over its spot Added two arrows to show where it should go STEP RETRIEVE A Added the piece in the spot it should go The problem I have is that it shows the piece I tried to show twice. It shows it hovering above where its supposed to go and in its correct spot. It also shows the two arrows still. This makes it extremely hard to add new pieces. I get confused on which is the piece in the right position! It shows it correctly in View mode, but that doesn't help me. Does anyone know how to get it so that it only shows the piece in its final correct place?? Anything helps. Thanks, Nathan
