22-2. 3D Absolute Rectangular Coordinates

Three-dimensional Space and 3D Absolute Rectangular Coordinates in AutoCAD.


 AutoCAD Line in 3D Space

 
Absolute Rectangular Coordinates in 3D drawing are the same as in the 2D drawing just by adding a third dimension "Z".
Command is entered on the form of X,Y,Z after the command line you want to draw.


Look at the picture above. To draw a Line in 3D space is necessary to specify the coordinates in the following way.
  1. - Click on the Isometric button to switch to 3D view (toolbar View)
  2. - To set the point T1 is needed: a click of a button LINE
  3. - Type 5,4,3 (X, Y, Z coordinates) time point T1 positioned in 3D space by planes that we have set
  4. - To set the line ending point T2, type in the Command Line 12,8,8 (X, Y, Z coordinates of the point T2)
How does it on the plane?
So the sequence of commands as follows:

Command: _line [click on the button to draw the line LINE]
Specify first point: 5,4,3 [setting up the first point T1 - starting X = 5, Y = 4 and Z = 3]
Specify next point or [Undo] 12,8,8 [T2 set up the second point - the final X = 12, y = 8 and Z = 8]

Point T1 - look at the XY plane

Point T1 - look at the XZ plane

Point T1 - look at the YZ plane

Point T2 - look at the XY plane

Point T2 - look at the XZ plane

Point T2 - look at the YZ plane

15-13a. AutoCAD Export Coordinates Points to CSV

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

Image
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 ...
