Hello
Can anyone tell me why the following is happening. When trying to draw a line, staring on a grid point with snap on and inputting a length for this line to follow with ortho on, why does the line end up veering off the grid. In the screen shot I attached, this is an 8" long line with the grids initially set at 1/4" with a major line spacing of 4. The line does not follow the grid.
If you turn .BLIPMODE on, so you get evidence of where you actually picked, and start a Line on a Snap location like that, does the resulting blip sit on the grid intersection as expected, or is it also off a little? [Not that I know what to suggest, in either case....]
[I was tempted to suggest that maybe your ELEVATION setting was other than zero, but that could be relevant only if this were an isometric-direction view of an orthogonal-grid drawing plane, so never mind.]
EDIT: I was getting the same thing [Acad2019], but accurate at the origin, and "drifting" farther off, in the X direction only, as I got farther from the origin. If your image is taken from somewhere in positive-X-coordinate territory, that's the same kind of drift I got -- Snapping locations accurate in the Y direction, but at X coordinates a little closer to the origin than the grid points are. BUT after changing Snap and Grid size settings a few times, now it isn't doing it any more. I have no idea what made the difference.
