Welcome to Learn Vern.
I am (name) and I Welcome you all to today’s video.
In the last video, we learned about special lines, construction lines, and ray lines.
In today’s video, we will learn about multilines.
So let us first understand what is multilines? Suppose I am using a line command here, and I will draw single lines. So what is multiline? Multilines is when I want to draw more than one line in a single attempt. Okay. So to draw multi lines I will type ML and press enter and as soon as I press enter, here you can see I will get the facility to draw two lines together. Okay. So when I want to draw more than 2 lines at once, I will use multi-lines. And to draw a single line, we will use the line command as we saw in the previous videos.
There are many other things, such as while drawing multilines, if I want to draw a line with some specific point, suppose here for multi lines I will click ML and enter, so you can see here that whatever line I am drawing is is being drawn from the top portion or top point exactly which means if I insert any dimension as per my requirement, it will govern from the top point only. Okay. So if I want to change that, we can do that as well.
Suppose ML and enter and then I will type J and enter. As soon as I type J and enter, I will have 3 options available here, one is to draw the line from the top or with zero that is the center or the bottom means with the reference of the bottom line. So come let's see what happens with zero. So as you can see the lines that I am drawing are exactly from the zero means the center.
One more thing, I will type ML and enter, then I will select justification that is J and enter, and here I will select bottom, so the lines that I am drawing here, It will be drawn exactly from this bottom line means this line, according to that direction. Okay. If I select top and suppose here I give the dimension as 3, so my top line will be in the dimension of 3, then next I give the dimension 2, so exactly from this point, I will get a line with dimension 2 . okay. If I choose the center, and I draw a line from here, then I will get a line from the center which is 3 meters, then I will take 2, so exactly with the center, a line of 2 meters will be drawn downwards.
If I select the bottom, exactly a line with 3 meters will be drawn from here to here and the same way all the lines will be drawn according to this bottom reference here as I enter the dimension. Okay.
so according to the requirement of the drawing that we are making, we will select top, bottom, or zero means center. ok?
There are 2-3 more things. Suppose the multiline I am drawing right now Is a simple line. Okay.
My requirement is that I want to make a layout where I want to draw a road, so to draw a road, if we are new users in Autocad and don’t have much expertise, we will draw some lines like this, then we will draw the centerline, so I will draw one more line here, then we will select this line go to modification and from line type we will select a dotted line or any other line, so this process is very time-consuming.
But with the help of multiline, we have an option available wherein the layout of the road, we need 3 lines, 2 edge lines that are full lines or regular lines, and the centerline should be dotted, so I can customize that. Come let us see how?
To customize or edit any multiline I will type MLST that is multiline style. As soon as I enter MLST, Here I have a dialog box and I will click on ‘new’ here. As soon as I click new I have to type ROAD 1 as I am preparing a layout or designing a multiline, so I will type R O A D 1 here. Then I will click on continue. Here I can provide the description of the line, or the types or the dimensions in the description box. Then if I want to add the caps at the starting point and ending point of the line, I can add that too. I can also add an arc there. I can also add the inner arc there. And I can also provide angles for it. So these are the available facilities. Then I can also turn on the display joints where I can show the junctions or the midpoints.
Then here we can see the elements mean the multi lines that are exactly drawn there, which show that 2 lines are drawn right now. Here I can see offset, so what is offset? Offset means one of the multi lines from the center one line is exactly 0.5 above and one line is exactly minus 0.5 below. This means that the offset is exactly plus 0.5 and minus 0.5.
Now If I want 3 lines here, so for that I will click on add. As soon as I click on add, we have a line available here whose color and line type is by layer and the offset is 0 which means the line is drawn exactly in the center. So here we have an option where 0 (zero) is selected by default in offset and we will let it be zero only. Then if I want to change the color here I can change it.
Hope you are able to understand.
This is yellow so we will change it back to by layer. center. Then we will change the centerline to yellow and I will select the line type as this, so I will select this and click ok. Then if I want to change the offset, here I will change the offset of the bottom line to minus 1 . okay. So as soon as I click ok, here you can see that the offset has changed from 0.5 to 1 as the distance has increased. So in this manner, I can modify this as well. Again we will click on modify, and we have all the settings available here. Here I am changing the offset of the top line to 2, suppose I will change its color to red, here you can see the color has changed to red. okay.
So in this way, we can customize any multilines here easily. Okay. If I want to delete this line, then we have the delete option as well. I can also change the offset, color, and line type of all the lines from here. You can change or customize it according to your requirement. Then I will click on ok and then I will click on set current and ok again. Then again ML and enter and you can see here that all the lines are customized here according to my settings and a layout is prepared. so here these other options are available to me. so as I double click on the multilines here, these are the options that are available and we will know more about this later.
Right now it is important for you to know that when you type MLST and enter and then if you want to go to the default settings then you can click on standard and then set current here and when you draw multiline with set current, so ML and enter, as you can see the lines are drawn again with the default settings here. In this way by typing MLST and enter here, you can add as many lines as you want, if you want to draw 5 to 6 different types of lines in your layout then, Where you want to use multi lines, you can add those lines from here for example ROAD2, as the earlier one was road one and you want to add some different elements here than road1, that new road also I can prepare from here. ok?
So in this way, we can use multi lines and I have many more options available for the modification of multilines and I can change the offset for these multilines as well. ok?
So in today's video, we learned about multilines.
In the next video, we will learn about group and ungroup.
I hope you all will practice how to draw multi lines and during your practice, If you have any queries or comments, click the discussion button below the video and post there. This way, you will be able to connect to fellow learners and discuss the course. Also, Our Team will try to solve your query.
