17-8. AutoCAD TRIM part of the line

How to use TRIM - Trimming off part of the line in AutoCAD?


Modify Toolbar - Modify Menu TRIM in AutoCAD

TRIM command runs with the toolbar or from the MODIFY File Menu, Modify> Trim, or the command line prompt, type the command.
TRIM command can be cut off parts of the line

Trimming (cutting) line is done as follows: In the picture below, the text with blue is marked with a line that we need to cut or remove
Trimm command in AutoCAD


An example of trimming lines in AutoCAD



- click on the button Trim
- select an object (line), which is the limit for the cut (in this case the red line that will dotted line after the first selection)
- press the Enter button (DTM can on the desktop)
- click on the part of the yellow line crosses the red line, that is part of the yellow line that we want to cut.

Now you have this situation. The layout of the drawing after applying the TRIM command to AutoCAD (image below)

Example1 step by step (Applying TRIM in AutoCAD Draw)

Cut part of line in AutoCAD

Take for example the drawing below which will be cut off parts of circles (1 and 2) the rest of the drawing to get the look that we want.

Run Command TRIM by clicking on the button and then select that click on the lines of 3, 4 and 5 (because they are border line to which we need to cut the lines 1 and 2
Auto CAD trimming a part of a circle using the TRIM

Now press the Right Mouse button (DTM) or press Enter to complete the selection. Notice that the cursor is still a square shape (which means that we keep selecting those lines but now we want to cut, in this case, the lines 1 and 2, so click on the lines 1 and 2

Finally, press the ESCAPE key. Now our drawing looks like.

IMPORTANT: So the order of selection is:

  1. The first line of which is cut off (limit)
  2. The lines will be cut off, ie. Removed.

NOTE: Make sure you are all the lines in the drawing-binding, otherwise the command will not work Trim. If you do not command works TRIM enlarge the drawing and see the maximum bond point.

For example, see pictures below (Basically everything looks OK but the lines at a given point are not conected).

After High ZOOM of the desktop using the Mouse wheel. Do you that this is happening because you have a problem at the end of the art (especially in 3D).
Be sure to include OSNAP mode (as well as activate certain point) and increase when you zoom in one place have more binding (connecting) points.

15-13a. AutoCAD Export Coordinates Points to CSV

Image
How to Export Coordinates of Points Using LISP to AutoCAD Since this web tutorial is intended for beginners, here I will describe how to export Coordinates for specific points in the drawing. Take for example that the drawings have points that are set to specific coordinates (this is quite used in geodesy, but mostly  MAP CAD programs  and some already have built-in  LISP  Export programs). In the picture below, notice that I have created several points on the desktop. Note that with the cursor I have an extra cloud with the coordinate position if I click on the position where the cursor is currently located. (this cloud can be switched on/off at the  DYN  button (dynamic input) How to use LISP? To use this option ( export coordinates to CSV file ), a file that has the extension ' * .lsp ' is used. This so-called scripted code needs to be copied to the "some" folder. Usually this is the  AutoCAD folder  that contains other files with...

24d. Plot in Color Thickness Lines

How to Plot in Color and Thickness of Lines on printed paper in AutoCAD. If you probably have a problem with the  Thickness Line  (not to say the width of the line because some use this expression) on the drawing or the  Color Line  on the drawing. If you are asking any of the following questions: Why are all the lines of the same thickness? How to change the thickness of the line on the drawing we print to the printer (plotting on the plotter)? AutoCAD does not print Color on the drawing? Why these questions? Well there is reason. Print black and white drawings are done over pre-prepared  CTB file  (also in color). To have the lines do not look like a toe, you need to experiment with the thickness of the line. If you want to print a drawing Floor plan of a building and you want to distinguish it from outer walls of interior, portions of drawings that display windows, doors and the like. Then you will set different line thicknesses in the...

24c. Ucsfollow Command Rotate Drawing

Rotating Drawing MODEL in AutoCAD - Ucsfollow Command In the previous tutorial, I showed how to  Rotate the drawing within the Constituent/Component . Here is the possibility of Rotating the other way when Plotting Drawings. This method of Rotating images in Layout Model when plotting is often used in geodesy at plotting KCBR (particles) that copies of the cadastral plan, if the particles are bigger in size than A4 paper and can't fit into the framework of Model Layout. (eg, a plan was drawn at a scale of 1:2000 and we have plot on A4 paper, and " Plot scale " scale 1:1, in fact, we print it on paper dimensions are in scale 1:2000) That they would not plot on tracing paper A3 sometimes it is enough to rotate a drawing that plan and the rotation of the entire plan, a particle can be placed within the model. When rotating the drawing in  Layout Model/Paper  should bear in mind that the drawing in our real model does not rotate, no matter what we rotate conducted within ...
