Hello and welcome back to another ADT 2007 Lesson on Wall Cleanups and this is a pretty easy lesson here. We are talking merges and joins. So, let us start with the join and all I am going to do is I am going to go click on my 8 CMU wall. I am going to draw a piece of wall over there. I am going zoom in, I am going to add another piece of wall over here, and I am going to see there is the base line, there is the base line. What a merge does is you can take a wall like this now especially if there are similar priorities and materials and you can take those now and now I can click on this, I can right click and say cleanup, add merge condition, and then pick this as the object and hit there I am done.
Now, if I actually click on here, right click and I go back to my good old toggle graph line display, if I click on here you will actually see an extra little grip on here, a little minus sign so if I take this piece of wall and move it over to here, we do not have a problem. As soon as I move that because the merged condition has been set up, now you going to see this little anchor line and then if I click on this, it gets rid of that merge condition. Once again maybe I will make this the host. Right click cleanup, add merge condition, click on here, hit enter and I am done.
Now, I am going to go back, turn up my toggle, my graph line you can see this over here, boom! And now what happens is it does not matter, I can come back any time and I can take this and I can move that wall and it will do a cleanup because there is a merge condition.
Okay, if I go back and sometimes we can change the width of the wall. In this case, I cannot really stretch the width of the wall but if you have a flexible width, I can stretch this and start to make some columns or whatever I want to make off of this wall. Okay so merge condition and then you can click on it later right click, cleanups, remove all merge conditions, and then remove that merge condition. Guess what? That did not do it because that is not the host. This is the host, so now I need to go back in cleanups, remove merge conditions and I am back to that.
So, other than that, basically a merge will make them force a cleanup and that is it so I guess any time you want it, you could form a merge condition. If cleanups are not working, I would say use it sparingly but at the same time you might as well take advantage of the tool if it is there. So, merge basically again if they are the same type. If we have two different types of walls, we might not get such a nice condition. If I take this wall over here and draw that in there and I take this and I move this up to say somewhere off of here, I will add a merge condition, right click, merge, and this one enter and it is going to do that. What happen is once it does the merge, it is like a cleanup, it starts comparing the priorities again. So, why did it get rid of all the dry wall in the furring here, simply because the CMU is a higher priority so the CMU worked its way around just like your seeing right in front of you.
So, that is the priorities at work there so still merge condition, you can mix and match them and all the merge does is force a cleanup and after then it is comparing priorities just as if we had done it just like in our previous lessons.
So, the next one we want to talk about is join. Now, join is not really something I have used a lot of but what join is for instance if these two walls are exactly at end to end. First of all they will do a cleanup. Notice that the vertical seam line disappeared when I put that wall there. This is one wall this wall. The line has disappeared because the two base lines are touching and it is actually doing what is a cleanup even though they are end to end, these two lines are touching so it is doing a cleanup. Enter the same type of material and priority so then everything is good.
What a join does is I can take this, I can right click, and I can go straight to join and say join this and this and now that has become one wall. The thing with that is they have to be the same wall type. They have to be going in the same direction and the base lines have to be dead on. To do a join, the walls have to be identical wall types and they have to be exactly end to end with the walls.
So, if I took this and I did a mirror of this like that, that is a good condition where I could do that. There is my wall, there is another wall. Simply go in here. It is the opposite of break, join this with this and you are done. No big deal you can maybe read up a little bit on that. So, merging and joins just a couple extra tools to try to get in, help your walls, cleanup a little better with each other.
