Autocad line command absolute coordinates problem after installing 2018

[Frans.Hessels]

I have opened a pdf file in Autocad 2018. So far no problem. I rotated en scaled the pdf file to match the correct coordinates pointed in the pdf. I saved the result as a 2013 format dwg. 

I opend my work drawing and attached the "pdf" dwg as a X-Ref file. I opend the line command and typed in the real coordinates. The first point landed in the expected coordinate. The second point (without the use of @, osnap and ortho) landed not in the wright coordinate but in the coordinate plus the old coordinate.

For example: coordinates are point 1: (4,4) and point 2: (6,6) the line should be drawn between (4,4) and (6,6) but autocad now draws the line between (4,4) and (10,10). the coordinates are not absolute but counted together.

So I have a major problem.

Is there an answer to this problem in very short notice. I have installed the AutoCAD_2018.0.2_Update_64bit today.

Sincerely,

Frans Hessels

Hi,

I guess you do have the dynamic input on? If so try the same input with dynamic input off ...

Hi,

>>  but autocad now draws the line between (4,4) and (10,10). <<

This will happened if you use @ symbol before 6,6 like below :

Command: N LINE
Specify first point: 4,4

Specify next point or [Undo]: @6,6

But if you do it like below i suppose that every thing is going fine... isn't it? 

Command: N LINE
Specify first point: 4,4

Specify next point or [Undo]: 6,6

You work with dynamic Input DYNMODE (Systemvariable)) and RELATIVE-Input: DYNPICOORDS (Systemvariable)

Change Dynmode, or if you want to use dynmode >0, than change DYNPICOORDS to 1

See F1

If you want to keep dynamic input on, you can also change the behavior in drafting settings. Type DS at the command line then go to the dynamic input tab. Click on settings under pointer input and change relative coordinates to absolute coordinates.

Alfred,

You solved my problem. It was the dynamic input that was turned on. Now it's off and no problem anymore. Didn't know that it had such a influence.

Thanks.

I already face the same problem but now fix it read your instruction. Boss you are the great

Thanks.

what's the difference between absolute coordinates and relative coordinates?

[sthompson1021]

In the simplest terms, absolute coordinates are in relation to 0,0,0. Relative coordinates are in relation to a point you pick. If you start a line at 20,20 and enter #10,10 as the next point, the line will end at coordinates 10,10. If you start the line at 20,20 and enter @Anonymous,10 the line will end at coordinates 30,30.

Hello Megatimran96,

An absolute coordinate is an exact point. If you want to start a line in a given point you type the exact/stand alone coordinate. This is a coordinate in relation to the origin (0, 0, 0) of the WCS (World Coordinate System) or the UCS (User Coordinate System) depending in which you are working. 

A relative coordinate is a description of the distance from the point you are standing to the next point you want to move to. This can be a distance given in a (x,y,z) format or a length under a given angle.

For example: you draw a line and want to start at point (5,5,0) you type the exact coordinate: [5,5,0] [Enter].

The next point of the line is point (12,2,0).

Typing as next point: [12,2,0] will get you there. You were working in exact coordinates that way.

Typing: [@7,-3,0], meaning go from (5,5,0) a distance in x direction of 7 units, in y direction of -3 units and in z direction a distance of 0 units also brings you at point (12,2,0). Now you were working with relative coordinates.
