BEGINNER : polyline / line coordinates problem

I HAVE JUST STARTED MY AUTOCAD 2010 COURSE AND IM HAVING A PROBLEM,

Example: pline/line tool to draw recatangle 30,250 - 230,250 - 230,120 - 30,120 - C

when i enter 30,250 its fine but then when i enter the next point of 230,250 it adds it to the inital point and sends it of screen to 260,500 instead of 230,250, the next point does the same from 260,500 to 490,620.

very frustrating and an easy fix im sure

please help

Do you add "@" in front of coordinates set? Use it only if need to input relative coordinates, not for absolute ones.

Regards,

The coordinates that are entered at the command line have you drawing a rectangle that starts at the upper left-hand corner and proceeding in a clockwise manner. Trust me when I say it does work as I just tested it myself. You'll end up with a rectangle having dimensions of 200 x 130.

You do not have to include the "@" symbol. Here's the input...

Command: _line Specify first point: 30,250

Specify next point or [undo]: 230,250

Specify next point or [undo]: 230,120

Specify next point or [Close/Undo]: 30,120

Specify next point or [Close/Undo]: c

Check the setting of the variable DYNPICOORDS, at 0 the coordinates you enter are Relative, and 1 they are absolute.

Also check the state of DYNPICOORDS system variable – if is set to 0 will treat the input as relative coordinates.

Regards,

A print out of the coordinates using the List command:

Command:

LIST

Select objects: 1 found

Select objects:

LINE Layer: "0"

Space: Model space

Handle = 175

from point, X= 30.0000 Y= 250.0000 Z= 0.0000

to point, X= 230.0000 Y= 250.0000 Z= 0.0000

Length = 200.0000, Angle in XY Plane = 0

Delta X = 200.0000, Delta Y = 0.0000, Delta Z = 0.0000

thanks for the quick response folks absolutely brilliant unfortunately i am not entering the AT symbol. i think i have in advertentley clicked something as i have come this far with no problems.

Ok so i click on polyline, then enter starting point as 30,250 FINE then i enter the next point as 230,250 which sends the line to a point of 260,500, which as u can see is the two points added together, very frustrating to a novice !! What the heck is going on ??

see above post from Msasus, does changing the variable DYNPICOORDS solve it?

(To change the variable, simply type DYNPICOORDS on the command line and then 1 (or 0) to change it)

Thanks for your deference, but to be fair, you were the first to suggest that solution!

Regards,

the dynpicoords worked i changed it to 1 from 0, im very happy !! Thanks to everyone for offering help, my tutor usually takes 48 hours to get back to me and you guys helkped within 5 minutes, fantastic. NOW what the hell is dynpicoords

Thanks to all

...NOW what the hell is dynpicoords

its a mysterious beast that lives way up in the woods and feeds only of... hrmp, not the fantasy-story-forum, right.

Its part of Dynamic Input that some like, some use some parts of it and some (like me) switch it all off and forget about it. But now that you have some key words, you can search through Help (and this site) and find more info.

NOW what the hell is dynpicoords

It is a system variable (a name recognized as a mode, size, or limit) that controls the current method used to input coordinates on prompt: if is set to 0, the values are considered to be relative (that it, displacements from previous inputted point), for 1 the values are considered to be absolute.

Regards,

I don't think changing DYNPICOORDS would have an affect either way.

no, but perhaps an effect :wink:

Just for the heck of it I changed the setting from 0 to 1 and repeated the assignment. It did not change a thing.

Enter new value for DYNPICOORDS : 1

Command: _line Specify first point: 30,250

Specify next point or [undo]: 230,250

Specify next point or [undo]: 230,120

Specify next point or [Close/Undo]: 30,120

Specify next point or [Close/Undo]: c

Output was exactly the same. I think the OP messed up when inputting the coordinate values somehow.

I must admit, I did the same just now and as you, it didn't change a thing. But the OP said that it solved his problem so all is good. It could have something to do with how myck other Dynamic crap that you have on I guess.
