18-4. 2D Polar ABSOLUTE Coordinates

AutoCAD 2D ABSOLUTE Polar Coordinate System

AbsolutePolar Coordinates Command in AutoCAD


UCS placed on Absolute Polar Coordinate system


In the picture above you see how it looks coordinate system for drawing the ABSOLUTE POLAR COORDINATES.

Absolute Polar Coordinates of the points that are located at some distance from the origin UCS at an angle and have a certain distance from the UCS.

When working with Absolute Polar Coordinates it is important to note that the same as when working with Rectangular Coordinates Absolute UCS we remain always in the same position and are based (placed) on it, and we must take into account when we take distance from the UCS. An additional difference is that in dealing with the Absolute polar coordinates work with angle as the other member.

IMPORTANT! Remember that in working with Absolute polar coordinates always start from the origin and UCS no matter where UCS was placed in the drawing (the desktop). So we always X = 0 and y = 0 as a starting point (starting point).
This is true for the UCS, which is set to start drawing and you did not move (positioned at another location), but in this case is again the starting point UCS



While entering the coordinates of the first to show the distance from the UCS (Origin) and then the angle that will be located that point distances. the same sign are separated by less "<".

Before drawing you must run the command that we want to draw a Line or Polyline, etc, and then enter the distance from the Origin point (UCS) and the angle at which it will reside.

EXAMPLE 1

Command: LINE [start order]
Specify first point: 10 <75 [entry away from a UCS-10 at an angle 75 °]
Specify next point or [Undo]: 10 <35 [entry away from a UCS-10 at an angle 35 °]

EXAMPLE 2

See an example of working with Absolute Polar Coordinates. (Distance <Angle)

Command: LINE
Specify first point: 14.14 <45 [distance from the UCS and the angle 45 °]
Specify next point or [Undo]: 22.36 <27 [distance from the UCS and the angle 27 °]
Specify next point or [Undo]: 25 <37 [distance from the UCS and the angle 37 °]
Specify next point or [Close/Undo]: 25 <53 [distance from the UCS and the angle 53 °]
Specify next point or [Close/Undo]: 22.36 <63 [distance from the UCS and the angle 63 °]
Specify next point or [Close/Undo]: 14.14 <45 [distance from the UCS and the angle 45 °]
Specify next point or [Close/Undo]: ESCAPE [end drawing]

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 ...
