Osnap to selected dimensions only?

[Anumet]

We've recently moved from drawing in 2D to 3D. From 2D I'm used to using the osnap function a lot, but in 3D using the osnap means I often end up setting the wrong height on the object. Is there a way to set osnap to disregard the Z-dimension when snapping / only snap to the X/Y coordinates without altering the Z..?

Thanks!

Hi,

I've not used it before yet but i think if you go into the Options and go to the Drafting tab, there's an option under Object Snap Options (bottom left) called Replace Z value with current elevation..

Just click to tick and this should ignore any Z value you click on and use the Z value of the current ucs..

I hope this helps..

Odd, I only have "Ignore Hatch Objects" under Object Snap Options. (Acad 2005) Any idea if there's a line command to activate this feature?

Hi,

Sorry my bad, that was for AutoCAD 2006, forgot to ask or say. I don't think there is a 2005 or pre-2006 feature for this but i could be wrong. sorry..

If you don't mind hitting a button or typing a few keystrokes before selecting a point you could use the following lisp. It is similar to the ".xy" filter but saves a few keystrokes. When prompted for a point, you can type " 'xy " to start the lisp then select point; the routine returns the "xy" of the point to the command. Or assign the lisp to a button.

(defun c:xy ()
(setq pt (getpoint " z being filtered: "))
(list (car pt) (cadr pt) 0.0)
)
