how to disable the delta Z value by default

[Anonymous]

Hi All,

My customer is using autocad 2014 and find that sometime when he draw a line and select it, the properties show that there is a data in the delta Z value field, this cause confusion to customer since the length calculation is included the Z value, customer doesn't want the length calculate in 3D, my question is how to disable the delta Z value? In not able, any other solution?

Please note that I am not looking for how to flatten existing drawing, I am looking for how to set the Z value default =0

Hi,

>> I am looking for how to set the Z value default =0

The sysvar ELEVATION (>>>details<<<) defines the default Z value (based in current CS) to be used for 2D-coordinate-input (just X,Y).

But when you use object snaps and want to avoid that the Z-content of the snapped point is used for the point input (e.g. start point of a line) you can set OSNAPZ to 1 (>>>details<<<).

>> Please note that I am not looking for how to flatten existing drawing

As you can not avoid that the user creates his own UCS you also can't avoid that there are objects at Z <> 0 (based in WCS). That has to be trained then like "how to use UCS and OSNAP correctly".

Set the system varaible OSNAPZ to a value of 1.  

Everything you draw will ignore the Z value, even if you are snapping to an existing object that has a Z value already.

The user must simply use the command PLAN and select CURRENT.  After typing in those two commands his new lines drawn will have 0  for the value for Z. This is true no matter what rotation the user's UCS is set to or even if he sets it to a defined view. Keep in mind the existing lines and objects which were present prior to running these two commands may still have Z values other than 0.

It is strongly suggested if a drawing is 2D only, that WORLD be used as the default UCS rotation setting, especially if the drawing is to be shared. A rotated UCS in one user's drawing may not be aligned correctly in another user's drawing.

thanks I inform customer to set ELEVATION =0 , then he said it works!

OSNAPZ doesn't seem to be an option in ACAD 2017... am i missing something?

Why do you think that?
