How to start a new line at a specific intersection of another line

[Anonymous]

I have drawn a box, that is 800cm x 3380cm.

On the 800cm line at the top, I need a line that starts 240cm in from the left, and goes down the 3380cm line 1800cm.

I can get a rough start point, but i can't find a way to specify the actual points with numbers. How do i do this?

Hi,

You can start at specific intersection point by using osnap modes ( Object snap ) . INTersection mode will Snaps to the intersection of geometric objects . Also you can draw lines by many ways (Using Specific Coordinates , Using a Relative Coordinate , A Specific Length , At a Specific Angle and At a Specific Angle to Another Line ) . >> Click <<

Command LINE

key in .y

Snap to endpoint

then key in your distance.

With OBJECT SNAP TRACKING [F11 key] and Coordinate Filtering.  Turn Osnap Tracking and either Polar or Ortho mode on, and have ENDpoint or INTersection Osnap mode running.  Start a LINE command, hover over the upper left corner until the little green plus sign comes on there, drag rightward and type in 240 for the start point of the Line.  Then type in .X, pick on that same corner to pull the X coordinate of the next point, drag downward and type in 1800 to get the second point.
