How to remove part of the line in the autocade. Trimming images in autocada, if you have nowhere, and there are no other tools

In this lesson, we will study the trim command to lengthen and learn how with its help it competently crop lines.

The command allows you to trigger the lines specified by the user relative to the objects in advance of them selected, or vice versa - reach the lines of the arcs or segments to what is a certain primitive on the drawing.

First of all, the program will require choose objects. Important ! First of all, we select not those objects that we will shorten or lengthen, and the one relative to which we will perform undergrowth.

After selecting the base object, press PCM and indicate those segments that we want to cut or lengthen. Important ! If we perform trimming objects, you need to specify on that part of the segment or arc that we want to remove.

Pay attention to the prompt in command line or dynamic input: when you press the SHIFT key and selecting any object, we will extend it if initially chose the "Trim" command and vice versa.

Did you know that in AutoCAD absolutely illiterately scaling the drawings immediately on a large canvas, that is, in the space "model"? Yes, this is the truth that few know about. Sadly but fact. But you have the opportunity to solve this secret of us how to quickly ask and painlessly change the scale of the sheets on sheets in the autocada. [...]

Counting the area in the program AutoCAD can be performed different ways. The value of the surface area is used in various calculations: useful or snow load, the volume of work on finishing, or simply, the direction of the area of \u200b\u200bthe room on the plan. The two most common ways to measure the area are presented in the video below. From it you will learn how to easily consider the square in the autocada. Learn to work quickly in [...]

In this article and video tutorial, we learn how to create tables in autocada. The "Table" command is on the ribbon. We find it and click to insert the table. A dialog box appears in which you can set the size of the future table, by regulating the number of its columns and rows, as well as their width and height. After setting the parameters and pressing OK, [...]

The last stage of the construction of the drawing is the final design of the circuit of the technological groove. Of course, this task could be solved by applying four times the tool Conjugation (using tool Similarity To create the upper horizontal line contour line). However, we will consider another tool that will allow us to solve this task a little faster. This tool is called Trim And it is intended for trimming lines speaking beyond other lines or drawing objects. As in the case of a tool LengthenTrimming is performed in two stages. At the first stage, the auxiliary lines are selected since the trimming of the lines is performed until the intersection with them.

1. Run the instrument TrimBy clicking on the button Trim Panels Change or choosing the command from the menu Change »Trim either entering the command in the command window Trim or simply obr.. As with the use of mosquitoes Lengthen, AutoCAD in the command window will offer you to choose objects that will be used as sequential edges in this case.

2. Select two vertical lines created using the tool Similaritywhich denote the right and left vertical boundaries of the circuit of the technological groove (Fig. 2.20) and press ENTER to complete the selection.

Fig. 2.20 lines chosen as sequential ribs

3. Select a horizontal line that denotes the bottom line of the contour to the left or right from them (Fig. 2.21).

4. Repeat the operation described in paragraph 3, but this time, select the remaining bottom line segment, protruding over another secreting edge.

Fig. 2.21 Selection of the right segment of the lower lines for trimming

5. Press ENTER to complete the command. Trim. We are only left to create the top line of the circuit of the technological groove, and then crop the upper parts of the lines that we have just used as sequential ribs.

Note. Cancel unsuccessful command Trim can be entered in the command window Cancel or simply about either clicking on the button Cancel Toolbars Standard..

6. Using the tool Similarity Displays the lower line of the groove contour of 30 units.

7. Run the tool again Trim And choose the top horizontal line of the groove contour (Fig. 2.22) as the Secret Rib.

Fig. 2.22 The top horizontal line of the groove circuit is selected as a secing rib

8. Pressing ENTER to complete the selection of sequential ribs, in response to the autocad invitation to select the lines to be trimmed, first left, and then right vertical lines, as shown in Fig. 2.23. AutoCAD will immediately trim the selected lines.

Fig. 2.23 The left vertical line is cut, now the turn is now right

9. Press ENTER to complete the command. Trim. By comparing the result obtained (Fig. 2.24) with the source drawing (see Fig. 2.2), we see that the goal is achieved. Several simple tools studied in this chapter will not only be useful to you, not only when studying the remaining chapters of this book, but also in everyday work with AutoCAD.

Fig. 2.24 Final type of drawing

If you feel that you do not quite confidently mastered the tools With lines, Similarity, Erase, Conjugation, Trim and Lengthen, You can try to repeat the creation of the considered drawing several times. In AutoCAD, there are no correct and incorrect methods for obtaining results - you can apply another sequence of creating a drawing or other sequence of using tools other than the author's proposed. In addition, you can try to perform the drawing, running all the tools using the input of their aliases in the command window.

Restrained, you can close AutoCAD without saving the built drawing. To do this, select the command from the menu. File »Exit Or just press Alt + F4. (If you do not want to leave AutoCAD, just close the current drawing by selecting the command from the menu File »Close or pressing Ctrl + F4.) In response to AutoCAD offer Save drawing Click on the button Not.

Now you are ready to explore the material of the next chapter, in which we will talk about the following problem. The object that is depicted on the drawing just created by us has dimensions 470 per 400 units. In this case, we can assume that it is about millimeters. However, such an assumption can be made far from always for example, if we have a 10-unit electric generator shaft drawing of an electric generator with a length of 10 units, then what length this item is in reality: 10 mm, 10 cm or 10 m? In addition, the drawing of the office stand corresponds to the default dimensions of the AutoCAD window, so we have no problems in this sense. But imagine that you really need to create a drawing of a 15-meter electric generator shaft with a diameter of several meters! Finally, if you create a drawing for foreign partners that operate not metric, and the British system of units, you will have to create a drawing not in meters and centimeters, and in feet and inches. Therefore, in the next chapter, we will talk about how to configure the drawing parameters in accordance with the user-standing task before the user.

Go to the "Image" tab → Cutting panel → Team "Create a contour of trimming". Next, you need to choose a suitable subparameter (in our case, "choose a polyline"). Then, in the drawing, select the previously created polyline and press ENTER.

The contour of the trimming can be inverted by pressing a small blue arrow, as shown in Fig.

To hide the contour of the trimming, you need to set the value "0" system variable.

9 Team "Trim" in autocada

When constructing, fragments of segments, arcs, etc., which "got out" outside objects are detected. To trim such fragments in the auto channel serves the "Trim" command. Cuts, rectangles, splines, rays, etc. can also be used as trimming elements.

Cutting in the autocada is carried out by specifying the so-called cutting edge and fragment of the object, which after crossing with this edge must be removed.

You can call a command in several ways:

On the tab "Home" → "Editing" panel.

Introducing keyword "OBR"And then click "ENTER".

First you need to select the cutting edge (or edges), and then select Cropped Objects.

Example. You need to cut a part of the segment that came out beyond the rectangle. In this case, the cutting edge will be the rectangle itself, and the cutting object is part of the segment outside the rectangle. The whole process is presented in the figure.

Cutting edges, like trimmed objects, can be a lot. For example, sometimes all objects or most of them are allocated as cutting edges. And then click the LKM on the elements that we want to cut. Immediately after specifying the object, its trimming is made. You can finish the trimming by pressing the "ENTER" or "ESC" key. Parts of the cutting edges themselves can be as clipped objects.

If you select Cropped Objects, selecting with the "SHIFT" key, then objects will not be cut, but lengthen. When you select Cropped Objects, you can use the following options:

✗ Line and edge - allow you to choose cutting objects using a time broken line and a securing frame.

✗ Edge - Enables / disables the edge continuation mode to imaginary intersection. When the trimming mode is enabled, the AutoCAD will also be made in cases where the cropped object is not clearly intersects with the cutting edge. This mode is enabled or not, it is seen from the command line request when calling the "Trim" command in the auto channel.

If it is written "edges \u003d without continuing," this means that the mode is turned off. You can enable it before selecting the cut objects by entering into the command line (or just from the keyboard) the letter "C".

✗ Cancel - An option that allows you to cancel the upstream object without canceling the fulfillment of the entire command.

✗ Delete - This option allows you to delete any objects without interrupting the execution of the trim command. After you use any option, you will return to the instructions of the cut objects.

(Finished p. 75)

Frankly, such operations are best done, following the "golden" rule of Voland - "treat this similar to". It is better to cut a raster pattern in a program that is specifically designed to work with such objects, in the same photoshop. What to do it in the Word, squeezing in the browser or cutting raster image in autocada.

After all, the idea is very simple - why insert an image of 1,000 to 800 in size to the Web page and the volume of 20 MB to compress up to 150 per 100, then the volume will remain in 20 - and traffic during download, and the place on the server hard drive, We will consider that the pictures of such may be up to hundreds. Create this version in Photoshop by the desired size, it will be weighing only 100 kb. So, one thing to download 20 MB, and another thing is to download 100 KB, 200 times less!

Approximately the same thing can be said about autocadging, which, with a complex drawing, creates pretty voluminous files - do not forget about 3D, tinting and light sources. In general, it does not prevent to always help yourself, and you can be sure - the program will help you.

Nevertheless, there are different situations. In the end, there is no touch and a suitable tool, and there is no time for this work. Then the autocadus can help solve this task - how to trim the picture, behind which the drawing is not ridiculous.

Some pretty simple operations, almost like the Word

The work order is quite simple and much different from work in the same text process from Microsoft - Word.

We act as follows:

Advanced possibilities trimming

But at the disposal of the user is not only a simple rectangular contour of the trimming. The contour can be any. Moreover, it can be done even inversion - the invisible will become what falls inside the contour.

To create a "broken" contour:

1. After selecting the circuit creation command, select the "polygonal" mode.
2. Following the image, create a polygon according to the usual auto channel rules.
3. As a polygon will be closed, trimming will occur.

Perhaps during the creation of a polygon will interfere with the installed binding mode. In this situation, the mode can be temporarily disabled in the status bar.

Cancel of cropping (as elsewhere called operations) is made by selecting on the "Condition" panel for the selected image of the "Remove trim" command.

Operation through the command line

Crossing operations on the command line corresponds to the "_imageclip" command. It is called on some versions of the program through the "Modify" / "Clip" / "Image" menu ("Conversion" / "Pruning" / "Image"). Here is the procedure for using the team:

1. First, a picture selection appears, if this has not been done in advance, before launching the "Select Image to Clip:" command.
2. Then a general query "ENTER IMAGE CLIPING OPTION : "- Creating a new circuit (new - is accepted by default), delete it and restore the full view of the image (delete), temporary trimming (OFF - it remains, simply not yet applied), turning on the trim again (ON).
3. If the creation mode is selected, the "ENTER CLIPPING TYPE is selected. : ". By default, it is proposed to use trimming through a rectangle - Rectangular, but you can choose a polygon - Polygonal.
4. When choosing a rectangle, it will be necessary to specify the upper left - the lower right corners, and when choosing a polygon - specify the angles, the polygon is initially accepted by closed, so the user circuits according to the rules of auto channel does not require - complete the construction by simply pressing on ENTER.

If you have a task to cut part of the block or array, to cut a block or an array on a specific office, then you probably have already noticed that the team Crop (_trim) In this case it is useless.
At least until the block or array is blown up. About how it can cope with this task without dismembering blocks and without breaking arrays, will be described in this article.

Looking ahead, I will say that the team will come to the aid Cut (_Clip). And to read it was more interesting, I will not just describe the procedure for working with the team, but I will show specific examples of its use.

Example number 1. Trim block

There is a truck block with a cargo that partially drove into the hangar. It is required to hide part of the block, which is inside the hangar. Block the unit and manually crop out all that inside the building is quite painstaking, and we will work with such an object very inconvenient.

Select a block. Go to the tab "Insert" Ribbons, panel "Link" And choose the team Cut (_Clip)

A request will be displayed in the command prompt:

Note that the option <Новый> chosen as defaults (triangular brackets talk about it), it suits us, so just press SPACE or ENTER.

Next, we will be asked what exactly we want to use under the contour of trimming - an existing polyline, a polygonal or rectangular area. The option is suitable for us Rectangular - Note, it is offered as default, so we just press again SPACE or ENTER.

Then you need to specify the first corner of the block area that we want to save, and then the second angle - this is done two consecutive clicks of the left mouse button (LKM):

Here is the result we get:

The trimming was successful, but we see the contour of the trimming, which in this case we do not need. To control the contours of trimming, you need to select one of the three options for displaying the contours in the tape:

Select item Hide contours. Now the result really suits us:

I draw attention to the fact that when the block is highlighted, the contours will be highlighted, and more so interactive - i.e. You can change their moving appropriate markers and the result of trimming will change, which is quite convenient:

Example number 2. Cutting an array with a tile along the contour of the room

IN this example We will look at a very useful case for those who are engaged in interior design, and in particular, laying tiles in AutoCAD. The description will be less detailed, because We have already considered the foundations in the first example, here I will dwell only on those steps that will be different.
So, we have a bathroom wall, a tile in which is decomposed with a rectangular array:

As can be seen, the array goes beyond the walls, and moreover, you need to make a slot under the door. Bring the array and cut it we do not want, yes it will not work, because In the pattern used hatching.
The beginning will be as in Example No. 1 - we allocate an array, call the command Undercut, Zhmem. SPACE or ENTER to create New contour trimming. But this time choose the option Polygonal:

Now we need several clicks of LKM. Sequentially specify all points of our circuit and after specifying the last point to click SPACE or ENTER:

A total of 8 points turned out, and the result of trimming is presented below:

Agree, very simple and convenient.

Example number 3. Creating your hatching (textures) from block

We have such a detail:

The part is made of timber and this species - This is the ends of this very timber. We want to apply on the end to the texture that would resemble the annual rings of the tree and would simplify the visual perception of the part. To do this, create a block of concentric circles, about this species.
