"Point or option keyword required"

[julioahernandezd]

I was drawing with the command "pline" then i wrote "@1" "Enter", then I selected "undo" and i wrote another number "@2" "enter" but this time it says "point or option keyword required". How do i fix this?

Sorry for my english.

Thank you in advance for your support.

Hi and Welcome to AutoCAD Forum,

>> .... then i wrote "@1"

This value is invalid !! When a command prompts you for a point, you can use the pointing device to specify the point, or you can enter its coordinates. When dynamic input is turned on, you can enter the coordinate values in a tooltip near the cursor. I suggest to follow this   Link   that will help you how to use Specific Coordinates & Relative Coordinate.
