TOPIC: HOW TO USE ARRAY STYLE POLAR ARRAY IN AUTOCAD
Welcome to Learnvern.
I am (name) and I welcome you all to today’s video. So, in the last video, we learned about “How to insert symbols in the text” . That is where we learned about how to add different characters and symbols. In today’s video, we will learn about “Array Style” where we will learn about the first style which is “Polar Array”. So, let’s start today’s video. So, today we are going to learn about “Array Style”.
In AutoCAD, a facility is available i.e. a command is available with us which is “Array Style”. So, firstly let’s know what is Array Style? meaning if you want to draw any object multiple times and to draw in a specific format like suppose if I draw a circle here… and I want to arrange this circle, to draw this circle in a fixed row and a fixed column like I am taking the option “copy” from here… I have selected the object, entered it and here I want to do multiple copies so, “M + Enter”, so here after selecting, according to my requirement of row and column, I can draw like this. (6 seconds gap) So, here you can see that the distance is uneven here, between two rows and between two columns. So, this is a hectic process and for that, a facility is available in Array where if we use array command so we can make multiple copies in three ways that are in array style we have three options available. Suppose if we want to set any circle in polar which means set at “360” degree angle, so, we will use “Polar Array” and if I want draw any object like, here I have taken an object as circle and I have to draw this object in a pattern that is in columns and rows then I will use “rectangular array” and like here I have once again taken the object as circle and I want to draw that object or circle in a fixed path. meaning We have this shape available and in that shape, we have to draw that object multiple times. So, we will use Array Style. Here are three styles, “Polar, Rectangular, and Path”. So, in this video we are going to learn about “Polar Array”.
To start a polar array, first we need an object. For object, here let’s draw a circle….and suppose I have a shape available that is also a circle. Now what I have to do is, I have to arrange or set up this circle in a polar array. So, I will use the ‘array command’ and to use it I will type “AR”, this is the shortcut key of the “Array command”. And after that, I will get an option to select the object meaning which is that object that I want to divert or draw in array style. So, I have selected the object and then entered it. Then the three options will be available to me for diverting or growth, whether i want to choose “ Rectangular or Path or Polar”. Right now, my requirement is a “Polar Array”. So, I have selected it. Then I have to specify the center of the arrangement. So what is my requirement?
This is the circle, and on its 360 degree angle which means all around the circle the other circle should be set and drawn all around it. I will select this center and then you can see that my object has been drawn here at a 360-degree angle. So, when we will press enter here, we will get these many options available on the upper side.
So, firstly here is “items'' , that is if according to my requirement I want “10” objects so, I will enter that and then you can see that my object i.e. my circle was 6 earlier, now the number of items is 10. So, like this, I can set up. Then we know here that the angle is “360 degree” that is polar, that is a complete circle and in that it is arranged, if the item is 10, then the in between distance or in-between angle, it will insert 36 by itself only. Because 360 divided by 10 is equal to 36. If I require the polar array to be 180 instead of 360, that is in a semicircle, then here I will insert “180” and enter and you can see that the items are 10 and the angle from starting to end is 180, and according to that the in-between angle or distance, it will insert 20 by itself. One more time I will press “CTRL + Z”... we will see one more time. Let me first center the coordinates ok? So, according to my requirement, I want to set/draw this circle here, so, for that I will go “AR + Enter, if I don’t want to use the shortcut key then I can select from here also, what I need to do is polar array. Then I will select the object, enter it, and then I have to specify the corner and if i select this corner, you can see that it is set. If I want to change the number of objects from here, then I can also do that like “10” enter. You can see that 10 objects have been made. Okay? Then the path polar which is from 0 to 360 and my requirement is 270 degrees only then I can also do that. If my requirement is 180 then also I can do it. right now, we will keep 360 only. Something like this. Then there is an option available beside it that says how many rows do I have to add in it like the distance here between these two is “2.03”. and we have one row available, that is the whole object is available in one line only in polar. If I want two lines of it, then I will do “2” here and enter. And the actual distance is “2.03”. if I want to increase the distance, that is my requirement is of “4” and as I enter 4, you can see that the polar object which has been formed there, the distance between both of them has been increased. Suppose my requirement is of 3 rows and I will insert it, then you can see that when I am adding a row here, the total distance is also added. That is, from the first object to the last object, the distance will be multiplied here and according to that, the total distance will be shown here accordingly.
If I do some changes here like the in-between distance, then the lower one is changed. if I change the distance here, suppose “10 and enter”, then you can see that it will adjust the in-between distance according to itself and the object will be drawn. Then comes “Levels”. That is when we see anything in 3D. Right now what we are drawing is in 2D,which means in X and Y directions. If I want one more level. That is where you can see that, with shift, if I move it here then you can see that only one level is made here in 2D. Suppose if I do 2 levels here according to my requirement, then you can see that here two levels are made. Okay? If I require that I want 5 levels, then I will make 5 then you can see that 5 levels are made here. The distance in level is of 1, if I change here to like the distance of 3 and enter, then you can see that, whatever I have inserted here, will automatically set here. Okay? And according to that the total distance here, that is the distance of bottom, from there till here is “12” like this is 1 gap, 2, 3, 4.
There are four gaps with a distance of 3 so, the total is 12. Okay? We will once again go to “View” and from there we will go to “Top”. Okay? As we will go top and select on this, We will once again make level as 1 and enter. Okay? Because the work we are doing is 2D. If I want to make any changes to it, then also I can do like on an object, if I select here then once again those options will be available here. then this is “Base Point” if I want to select the base point, then also I can do that and with that the movement or copy or if I want to do the scaling of it, then I can do that. Okay? Then there are “Rotate items”. To explain rotate items I will draw here a circle and with circle the another shape is ( 6 seconds, drawing) a rectangular portion. Ok? Something like this. Now I want to polar array of the rectangular object. So, I will go to “AR + Enter” and select the object, one more time enter, and I am using polar here so i will go inside polar and this is my center. Here you can see the arrangements done here are actual arrangements, in whichever direction you are moving it, according to that the object is changing its direction, why so? because here I have selected “Rotate items”. If I turn “off” this, then you can see that the direction of my basic object, those objects will be set here in the same direction. one more time I will go to “Rotate Items” and according to that whatever the direction is, it will be selected. Okay? Then there is direction so, if I want to give direction clockwise and anticlockwise, then you can see that this arrow here is moving anticlockwise. If I turn “Off” the direction, then according to that it will move clockwise, whatever changes I apply, will be inserted here. Okay?
So, I will do 180 here and it will be inserted here. from here to here 180 and this side will be empty. Okay? If I change the direction here then you can see that the arrangements will be this side, till here it is 180 degrees. So, if I keep the direction “ON” then according to that the pattern will be here and if I keep the direction off, then according to that the pattern will be here. one more time I will make it 360 so that the direction can be equally divided. Then if we want to edit it then how can we do it? So, for that we will go to “Edit Source” and select the error and then “OK” and then you can see that the rest of the object will not be selected here. only the basic object here, that only will be selected here. one more thing if I do some changes to it like if I draw a circle here, then you can see that this circle has been added to the rest of the objects. Let’s see one more time. If I add one more circle here, from here to here. then you can see that this circle has been added to the rest of the objects in which we have used the array command, changes are applied. Okay? Something like this. (7 seconds pause)
Let’s see one more time. If I delete the changes or the circle here then you can see that all the circles are deleted. Now to exit from here and i need to save changes then you can see that whatever changes I have done here, all those are already applied here in all the objects. one more time I will select it. If I want to replace this item, then also I can replace it. So, for that I will make a square here then I will select it and I want to replace this. Then I have to select that from which I have to do the replacement. So, this is a replacement item. Then I have to enter here and from here I want to replace it and it is done. Then “Select an item in the array to replace”. Then it is done. Okay? So, you can see that this item has been replaced here. and then enter. Okay? And then exit.
So, you can see that this item has been changed. Let's see one more time. “CTRL + Z”. I will select on it, then replace it with this item, enter and (4 seconds pause) here I want the sources and you can see that I did “OK” here and then all of the things here will be replaced here. Okay? Let’s see one more time. first I will do the “save changes”. We will go in this. If I want to replace then I will draw an item here like a circle. Then I will select this for replacement, go to ‘replace the item’, I want to replace with this item, and then enter, and I want to replace from here and enter, okay? And exit from here….Let's see one more time, maybe there is an error with the command. I have selected this, replace the item, and then select from here, and then enter, and this is my base point, then select this item, then you can see that whatever item I click on, it will be changed. okay? Escape.
then you can see that whatever changes I have done are applied over here. if I want my earlier object back, so I will do a ‘reset array’ and with that, the default objects will come back here. Okay? Let's see one more time for the last time. I have drawn a circle and a rectangle shape something like this. Then I want to array this shape, so I will go to “AR + enter”. Then I will select this object, and then enter, and then I have to do “polar array”, so, this is my center. So, like this my array is available. And here I will keep the rotate item turned ‘on’ so that whatever items and objects we have will change to such a direction and also will apply the changes happening in the degree. If I turn it off then according to first object all the objects will be copied, like earlier. So, I will keep this “ON”. Then I will select the base point, one more option is available over here, which is associative that is if I keep this on, then in future, if I want to edit here, I can edit that. If I turn “Off” this and escape it then you can see that the edit option is not coming above. If I want to edit here then the option is coming here because when I draw, then I have converted that item into an associative. Okay? Let's see for one more time. I will delete all these objects.
20:43 (14 seconds pause)
These are deleted. One more time I will apply the array here, “AR + Enter”. Select it, enter, polar, this is my center and here the associative is not there. This is not associative which means if you want to edit in the future, then the objects individually will be available in the future. If you want to edit the whole array or replacement, you can do that if you keep the associative “ON”. So, here I have arranged the polar and with that, I have kept the associative “ON” also and then I will close from here. So, when I select it you can see that the whole pattern is selected. If I want to do the replacement, then I can also do that. Okay? So, this is a replacement. If I want the replacement with this object, then enter, I want to replace from here, and then you can see that whatever object I select, will go for the replacement, they will be replaced. Then I will escape it and then according to that all patterns have been replaced. One more time I want it so, I will go to reset array so, then whatever the default array was for my system, it will be available once again. one more thing, if I edit here, if I want to edit this array, i will click “OK”, then you can see that the default array object is highlighted here and whatever changes I do in it like if I draw a circle over here, then you can see that whatever the properties are, the circle will be added in all the objects. I will go here and do “save changes” and escape it so, whatever changes I have applied will be applied here.
one more thing, if I want to increase the items in it then I can also do that like right now it is “6”, and I will make it to “10” and enter it, then it will be available like this. Then there is 1 row and I will make it to 2 then like this the two rows will be available. Then if I want to increase the distance in between then I can also do that. Then this is level, I can also increase the level. One more thing is there in it, if I make the level 3 here, then… you can see that the pattern is now available in three layers. If you cannot see it, I will click on it, and increase the distance here. Let's make it “5”. Okay? So, like this the layers are available. Then there is a command like if I select this, and here “increment” like if I make the first level at “0” and make the level of the other with some distance then also we can do that. Right now the levels are being drawn in one vertical line. If I want to draw this with shift and distance, then also I can do that like right now it is “0, 0” and we make it “2” then you can see that the position of the object has been shifted a little bit. I hope you can notice. If I make some more changes here,... let’s make it “10”, then you can see that like this the object is ready. Okay? So, the first level is “0”, then this is “10”, then this is “20”, then this is “30”, and this is “40”. Okay? So, like this, you can draw your object. So, you can see from here, that the two layers in between, the spacing is available here. Okay? (5 seconds) This is first row and this is second row. Now suppose I am adding a row here of 5. Then you can see that like this the object is now available. Okay?(7 seconds gap) So, we can available these all things with the polar array.
So, in today’s video, we learned about the polar array which means the first option in Array style which is Polar Array, how is it used?
