AutoCAD – Complete Tutorial for Beginners – Part 2 (commands of section "Modify")

Welcome again to this tutorial for beginners In this video I will introduce you to the commands of the “modify” section it is very important to learn how to use most of these commands from the beginning this not only helps you to modify objects but also to save time when you are drawing another thing when you activate a command of the section “modify” the pointer changes to this shape I’m going to start with the most basic commands they are “MOVE”, “COPY” and “ROTATE” i will start with the command “MOVE” it’s very simple so i will type “M” or clicking the button over there i will select the objects press “enter” now i will pick a point this one for example and now I click again to put the object in the new position this time i will move it “500” to the right of the “endpoint” now i will show you the command “COPY” this time i will type “CO” or “copy” it works as the same way as the command “MOVE” the only difference is that keeps the original objects this time i would choose this base point and i can copy the objects to where I want so i will copy them to a distance of “500” to the left now i will show you another and very useful way of the “COPY” command so we will activate the command again select all the objects press ENTER and select the basepoint if you look to the comment bar it says “specify second point” or “array” so i will type a to activate that and here i have to enter the number of items to array I will put five so you can see on the screen that we will have 5 items displayed in a row and, this is very important with the same distance between each other I will specify “2000” for the distance Finally I’m going to show you the command “ROTATE” so we are going to type “RO” or “ROTATE” I select the objects and press “enter” I’m going to specify a basepoint, for example this I can rotate the figure around that point so i can click somewhere for example here imagine that we want to rotate the figure to the position that it was before so if we do the same process now we pick a point our reference line will not be horizontal this time and when we place the object it will not be with precision this means that we have to use a different way ok we are going to repeat the process again and when we have to specify the base point we are going to type “r” for reference so i will pick two points for specifying a reference line the first one will be this and the second is another so with this way i can rotate around this line and to make it horizontal just use the “polar mode” for example now it says “polar” I can click as you see the figure is finally straight ok now I’m going to show you a command that I consider it very useful it’s OFFSET the icon is located in this place here and it’s used to create parallel lines and curves and also concentric circles i will show you an example with this polyline here i want to create an internal polyline with this distance specified as “150” I click on the icon and I will insert “150” for the specified distance I click on the object and now I click here to offset to the inner side so here it is now I have this line and I want to make multiple parallel lines i would type “o” for OFFSET and this time i will specified distance of “200” for example

I click on the line and now I’m going to type “m” for “multiple” so, with this I am able to draw parallel lines with the distance of “200” from each other now I want to show you the option through in the OFFSET command I will type “o” again now, instead of typing the distance I can type “through” and with this I can place the parallel line where I want So I will place the line using some object snap points as my reference for example this “endpoint” I will also do it at the top of this window and at the top of the wall here now that you know how to use OFFSET you can try it and practice we have an example of offset for an ellipse and an arc if we have a complex polyline with arcs included it also works if we have the same figure but splitted in lines and arcs the offset will be separately and this is what happens so if you want it like before you need to convert the lines to only one polyline and to learn how to do it you can click on this link in this section i will explain you how to trim objects so i have drawn these three parallel lines and also these two that intersects the others I want to cut off these sections and I will do it with the command TRIM which I have it there I will click on the icon and then I select the objects and type “enter” finally I click on the parts i want to remove so as you may understood this tool cuts any section between intersections now imagine if i want to cut off all these parts of the parallel lines i activate TRIM again and this time i will only select this line and the three parallel lines as I have left the diagonal one unselected it will delete everything to the left from the vertical line here it is so now, i am going to show you the command EXTEND you can find it clicking on the arrow at the right side of the TRIM command this is useful when we want to extend lines i am going towards another object I am going to extend the horizontal lines till the diagonal line I will select all I type enter and then, I click on the lines I want to extend so it’s done as you could see the commands TRIM and EXTEND are not difficult to use next part, I will explain you the command mirror it’s very simple and I will show you how it works for example I want to mirror this figure then i create a virtual mirror and finally the object will be copied symmetrically now I will explain the process slowly to activate the comment I could type “mi” or “mirror” or click in the buttom at the “modify” section I am going to select the objects and press “enter” now i have to specify the mirror line but i want the new figure to be at the distance of “100” from the current one so from the endpoint, I drag to the right I type “50” and press enter so I have specified here the first point of the mirror line now I need the second point in order to make a vertical line also also the length of the mirror line doesn’t matter only the direction I click and here i press enter again to remain the source objects another thing beforeI specified “50” for the distance from the object to the mirror line with that, I can have the total distance of “100” now I want to show you another useful situation to use MIRROR

if we need to create a symmetric figure we can just draw half of it and when I have to place the mirror line I will draw it exactly where is this endpoint I move up, click here and it’s done so if you need to make very complex symmetric drawings you can save a lot of time doing this way one last thing on this video we can also draw the mirror line in a different position of course I will make a horizontal line from this endpoint and, theobjects are now mirrored in this different way so it’s also possible to draw a diagonal mirror lines and I had the “polar mode” turned on to make sure my mirror lines were vertical or horizontal now i want to explain you the command FILLET and CHAMFER which can be used to modify corners as you can see here so the command FILLET will change the corner to an arc which i specify typing the radius the command chamfer will change the corner to a line which in this case I specify typing the distances from the corner to the intersections so I will start with the comment field okay I’m going to draw a rectangle with the command line and I will specify the dimensions as 100 per 50 ok once i finish i click on the command fillet which i can find it over there ok, so i will try to convert to an arc this corner I select this line and when i select the second line I realized that no arc was created this usually happens when i’m using the command for the first time as the radius is by default “0” ok, we are going to repeat the process again I click on FILLET now if I look to the command bar I can see all these options so, i type “r” for radius so now i will enter a radius of, for example, 10 i’m going to choose the lines again and as you see, I have put in this corner an arc of radius 10 now i will apply FILLET to the other corners I press ENTER talked about the comment again now I select this line and this another at this line and this is another and an arc was created with the same radius now i will apply to the corner below, but this time I want to change the radius to 20 I type “r” and enter “20” now i select the lines and it’s done in the next part, i will show you how to apply FILLET in polylines so I am drawing the same figure, but this time as a polyline instead of lines now that i finished, I type “f” for FILLET and this time i will enter “p” for polyline I enter “10” for the radius and when i and when I select it creates arcs for all the corners except this one where I started and finished the polyline if I want to apply to all the corners in one polyline I have to type “cl” to close it doing this, is like the polyline doesn’t have a start and an end so, the polyline will continue also in this corner i will use FILLET again and you can see that it is now applied for all the corners corners now I want to show you how to use FILLET, keeping the original corner I activate the command again and this time I type “t” as you see, i can switch between “trim” and “no trim” I chose “no trim” and when I select the object the original is not going to be deleted if I want to use FILLET in several corners in one time I activate FILLET, and then I type “m” for multiple and I am able to do the operation for several corners without need to activate the command again I’m going to show you how to use the command CHAMFER it works as the same way as FILLET but the corner will be changed to a line I will click on the arrow next to the icon FILLET and choose CHAMFER here then, I will type “d” for distance

now, for the distance one, I put 10 and for the distance two, “20” for example I press “enter” now for the distance one, that i put 10 I will choose this line and for the distance two, this line here so, this is how the command CHAMFER works also like the comment FILLET the options TRIM, MULTIPLE and POLYLINE can be used with CHAMFER how to use the command SCALE to change the size of an object basically this is used to increase or decrease the size of a drawing I recommend you to not use this command for printing purposes it’s better to draw always in the scale 1 / 1 however if you need to scale a drawing in order to print it you can check the link above to change the scale of a drawing I will click on the icon in the “modify” section or, alternatively, i can type scale or “sc” now i select the objects i want to scale and press enter then i select the basepoint and when I drag the pointer I realize the rectangle is getting too large as you see here, at the moment it’s using a factor of 35 it means that, if I click here the size of the object will increase 35 times and without any precision due to that, i will insert the scale factor ok going back I will set it as “2” and the lines sizes will change to the double now I will type the command “distance” or “di” so I can measure this line and as you see, the length has changed to “200” another thing, if this dimension doesn’t appear in your workspace you have to switch on this button that’s a dynamic input are also press “F12” if instead, I want to scale my drawing to a smaller size I have to insert for the scale factor a value under “1” for example if I insert “0.5” 0.5 the lines will be shrinked to its half now imagine that I want to change the scale in order to have this line as 135 so i will type the command again I select everything then I choose the basepoint now, if you look to the command bar there is an option called reference so i will type “ref” or “r” with this I will choose 2 points and type the new distance between them that I want so I just this as the first point and this as the second point now I want this distance to be “350” so it’s done and those are my new distances now i will show you another case to use reference with scale but this time I don’t know the distance I just want the length of this door to be exactly as this spacement in order to fit there ok I will do the same procedure as before I will choose now the base point i will type reference like before, I choose the two points of my reference here it is now instead of typing the distance I type “p” for “points” and then I choose these 2 points because i want to fit the door here ok, now these two distances are the same finally I just need to move my door there and it will fit exactly in that place so here it is the last method in this video I will explain how to stretch this figure to convert into this one and for that I will use the common stretch i will type “s” or you can also find it in the modify panel there and i press enter now i have to select the lines I want to extend and also the end section on the right but, I have to keep these lines unselected because i don’t want to move them after clicking “enter” i will pick this points and as you see i can extend the lines i’m going to type with the keyboard the length that I want to extend

so it’s done if for the same figure I select all lines except this first one I will move also the second vertical line another case if instead I choose all my figure this will be moving all the object and the STRETCH will not have its proper effect ok, this is everything for now if you liked this tutorial don’t forget to subscribe the channel to get access to the full list of tutorials of AutoCAD and I want to tell you that these lessons are also available splitted in shorter videos if you prefer so, thank you very much for watching and I hope to see you next time
