Autocad - Warm Up Drawings - Array Weave

All right in this video we're talking about the array weave now from the assignment. There is a link away, the array weave, drawing that you can jump into so that you can see how to create that array. Weave, okay, but this is set up so that you take a look at this object and you start to see the relationship between the repetitious nature of the part. Okay. So when you take a look at this, the hint here find the pattern then use the rectangular array. Well, there's a pattern of repetition: okay, finding that pattern of repetition is the key to this drawing. So i'm going to jump into my cad file where i created the steps to do this. Okay, we'll go through these steps, and you can see here. This is the pattern that has been blown apart and it's in an active array. If i were to take and highlight one square of that pattern, you need to see that this pattern breaks on a line, and this is where i want you to start to see things not like you're drawing with a pencil. But what you're, drawing with a pattern right, so one of the first things that you need to do is you need to recognize from the given information in the drawing okay, we're gon na go jump into this drawing and look from the given information here. We need to figure out how to build a pattern, so i'm gon na zoom in here a little bit and it says that the whole thing is six by six okay. So we could make one big six by six rectangle. So so we could do that or we can start with the the base pieces here. So, let's start with the base pieces first we'll build that six by six in a second. But let's start with this, so here we have 0.125. So i know that one of these lines to this line is 0.125. The next spacing is 0.125 also, so every single one of these lines, i can assume, is 0.125 away from each other. There'S a dimension over here that says the square in the middle is 0.25. So now i know that i'm working with pretty much all standard size dimensions - okay, 0.125 or 0.25. Here it's telling me that the spacing from the edge of the rectangle over to the first line is 0.125. So i can assume from this point to this point is 0.125. Then it's given 0.125, this spacing is 0.25 and then so forth and so on. Okay, so i can know what all the spacing is. So if i jump back here into my cad file, one of the first things i'm going to have you do is draw a line that is .75 long, because if we go back here and we start adding up this stuff, so we got 0.125 plus 0.125 plus 0.25 plus 0.1 see where this is coming to add up to be 0.75. If i were to look at this object, the distance from i'll just go ahead and put a dimension on it from here to here is .75. So that's where that line comes from okay, so we go ahead and we draw a line at 0.75. So i'll just do this right above where i have it drawn out just so, we can see that there's no fanciness going on and i'll get this on the right layer, and we haven't really talked about layers in here yet, but we will shortly all right. So we're on the right layer, so we got a 0.75 now number two offset the line up by 0.25, so you should know how to use the offset tool. So i'm going to go ahead and just take this and i'm going to just keep going along i'll copy this over to here. Just so, i'm working above every step and i'll use the offset tool, and now it says, specify offset distance in my command line. So i'm going to type in point one: two: five enter i'm gon na select that object, move up click and that there is step number two. Now, let's jump over here to three i'm gon na go ahead, hit escape finish that command and i'm just gon na keep copying this on down the line, sort of like an assembly line for me and then i'm gon na look at offset the top line up. 0.25, now we're going up 0.25 and the whole reason we're going up. 0.25 is because of this spacing right here: okay, so now we're working on that piece. So we're going to come back up to here we'll do that we're going to do offset tool, specify offset distance 0.25 enter grab the line come up and drop it there's the offset of the 0.25. The next step. Four, i'm just going to again copy mine over keep things rolling down the line and we're gon na up by 0.125 again so offset specify offset distance 0.125 enter grab the top line, move up top click all right hit escape finish the command on to step five. I'M gon na go ahead and highlight my stuff, i'm gon na copy it over just to keep making an assembly line of what we're doing, and now what i need to do is i need to start setting up my first vertical line here now. The distance is coming from the end of the line over by 0.25 and all that is coming from the drawing and at the top of the drawing it's saying up here: 0.25 0.125 from the corner over okay. So that's the spacing for this entire vertical line. Okay and then we start drawing the same piece of information in length which is going to be that 0.75. So, let's jump back over here and the way that i would recommend doing this okay is coming over and then coming up all right or we could go ahead and draw a line and move it into position. There'S a few ways to do this. Okay, so let's go ahead: i'm going to grab my line tool, i'm going to do this all with lines to keep it as clean and understandable as possible. All right, i'm going to first come up by .125 enter and i'm going to come over by .125 enter. Now, the reason why i did these two lines: okay, i drew these two lines as construction points, because i needed to then create a 0.75 line straight down across these parts. Okay, that spaces this line over from the end by 0.125 and it spaces. The start point up by 0.125 by doing that, it positions it properly. Now these lines i just used, i don't need these anymore. I can highlight these and just delete them, and now i have the geometry in the proper location. Now, on the sixth, we are right back into that same situation. We are going to start using that offset tool again like crazy, so here we're gon na offset the vertical line to the right point, one two so grab the offset tool type in 0.125 enter grab. My line move it to the proper direction click enter now we do the same thing again offset last line 0.25. So we'll highlight this: we're going to do a copy put it over here and now offset tool specify offset distance 0.25 enter, grab my line and move it to the correct area, click and it drops that 0.25 over and then you can probably just go ahead and Guess the last thing in the next thing, without even looking at directions, is going to be offset by 0.125 again, so we'll grab that offset tool point one two five enter grab the line and drop it there now. This is where we get to the point where we're going to just start doing some trim trimmity trims, because we need to trim up what we have all right. Now we are going to trim now. This trim is very similar to some of the last assignments. We'Ve done like cross boxes, rectangle boxes where we want to look at the drawing that we want to make and then get rid of what we don't need. So i'm going to grab my trim tool and i'm just going to look and mouse over the stuff. I don't want well here. I don't need these two lines down here, so i'm going to click on this one and this one and then here i don't need this one or this one. I come down here and we're going to click on this one and this one and then here i don't need these i'll do a little window across those and they're gone. So this is now the weave that we will use to repeat finish. My trim tool hit escape, and now this is what we will use to create the repeat: okay, all right so 10. The object above is the array object. Well, that's it right here we're not going to copy it to there. We need a 6x6 box now. So we can fill in some stuff, so i'm just going to say: let's grab my rectangle tool, click and pull 6 tab 6 enter. There is my box and then i'm just going to go ahead and position. This thing that i just built up here in the right place: well, how do we do that? Well, if i highlight it and grab my move tool where i really want to grab this thing is right here in this corner, but i don't have any geometry there to grab it by the corner, so i could go ahead and draw some lines: okay or what I can do is what you're watching me do right now on my screen. Autocad will actually give you a corner point to grab this thing by okay. Let'S do this again, so you can see this, because this is really important. You could very simply and i'll do this in a different color. You could very simply draw one line over then you can draw a line down and use that point right there when you highlight everything, grab the move tool and then move it from here to here that works, there's nothing wrong with doing that. Okay, you got to go in and delete these little purple lines and that's the part that gets to be a pain all right or just do some undo's. The other thing you can do - and this is really neat to see in autocad autocad - recognizes that things really do exist by corners and things like that, and sometimes you don't want to have to draw those lines. So if i highlight this grab my move tool, zoom in and i just sit over top of the endpoint once it says - endpoint and i start moving away from it. I get my my displacement to pop up. Then i'm going to move to another endpoint and it remembers the last thing i did i'm moving over moving over moving over to oh and it finds the intersection point for those two lines. So i'm going to left click and then i come down to the end. Point and left click again, so that is just another tool to position parts without having to have geometry set. So at this point we are ready to array our drawing now in the directions. It says: click on the array tool select the weave object only so, let's just do these together. Slow click on the array tool. Well, that's coming off of this ribbon bar rectangular way. Right there bam. I did it step. One now select the weave object only well. That would be this thing right here. So how do i select? Do i go in and click on each one of these look? No, that is way way way too difficult. I'M just going to click and hold. Well click. Not click and hold, but click come across this with a panning window notice. I used a blue window, not a green window. If i did a green window, i'd have to be a little more careful, but this way i can come across that box too, and not get my six by six all right. So i got that selected. It says on the top ribbon bar input 0.75 for row. Spacing between and points okay, so let's go back up here hit escape. Let me do this, so i'm going to do array tool highlight enter and net alright. So while we are in this array tool, we're going to come up here to column between rows between and the information i'm going to put here is the between the between is actually from this point to the next point of the next object. Okay, so i want the distance from this corner point to this corner point to be 0.75, so i'm going to type in 0.75 and then i'll click in a different cell, okay and notice they jump. Then i'm going to go up here and i'm going to put in my between as 0.75 and click in a different cell and they jump into position. So right now we got the spacing between 0.75 and 0.75, okay and and it's important to recognize that that spacing is based upon the distance from this corner to where the next object gets put. Okay. So it's from the corner to where the next object gets, spaced by column and row just means they're jammed up next to each other 0.75 in each direction. Now we need to fill the box. So, let's just do this slowly, let's just say we're going to take the columns and we're going to make them six. And if you click in any one of these other cells, it will show you what you just did so at six we're like uh. We need a little more so if i highlight this and say seven and click in a different cell still need a little more. Let'S go for eight and click in a different cell there. It is, it fills it in nice and neat. Now, let's go in the other direction, so rows, i'm gon na just go right for the full, eight and drop it in and there you go. So you can see that eight and eight point seven five breaks this out so that the array is now pushed through. Your six by six at this point we can say we are done in the array. We can hit close array and it's now closed. We now can take and move this thing around to wherever we want to put it. We can start the dimensioning process, just as we had dimensioned everything else so far, so just place these dimensions on here. If you want to put the hint you, can it's not necessary? What i'm looking for is that you have created the object and that you have dimensioned it so that it is easy to recognize that this is a six and that this is a six. And then, if you dimension one of these weaves we'll get to see that this is a point one two five, and that this is a point one two five and that maybe you just grab something from here to here, saying that this is point two five anything To this effect, uh will work out as far as dimensioning. For this point again, we haven't spoke about the mentioning and the specifics of dimensioning, so um. Any of this will work, try to keep your dimensions as neat and clean and uniform as possible, not running over top of things, and then this will work. So hopefully, this helps you guys get through this array, weave with as little hair loss as possible.
