Tough Questions - Override "Z" Elevation Lisp
AutoCAD 2007
I have a quite a few tough questions/requests and I am currently looking for some lisps to solve them. I have been doing some searching online to find the lisps I need, and although I have been able to find some stuff, I still have some things that I can't seem to find exactly what I am looking for. I would like to take the opportunity ahead of time to thank every who views my questions and for any help that is given.
Wondering if anyone knows of an override that will allow you to temporarily turn off "Z" elevations set to lines in your drawing.
For example, lets say you have contour lines in a site plan that have "Z" elevations set to them. If you try to get a 2d distance from line to line, the distance command factors in the "Z" elevation giving you an inaccurate distance reading.
Another example, when you want to draw a 2D line and you snap your line to a contour line that has a "Z" elevation set to it, the line in essence snaps to the "Z" elevation of the line making it 3D as opposed to 2D.
Does anyone know of a variable or a lisp that will allow you to temporarily override the "Z" elevations in a drawing?
