problems in bringing the quota z to zero in all entities with flatten

[Alex97]

how do you proceed to spy on all lines i.e. to take them on the plane or, with autocad 2016 I tried with the flatten command but not working?
Thank you.

It can happen that flatten does not work with everything. Sometimes it may be necessary to explode the elements you would like to move on the zero plane. It is always convenient to try to zero the z quota using directly the properties (some elements are to be done one by one. I happen with the membership fees that are particularly capricious). Finally I recommend you look for the lisp: zeta that seems more complete than flatten.

when it happens I make a select everything, in the selection property window the type of entity and I correct the value z by hand. obviously does not work as much as it is contained in the blocks

 

[Alex97]

If they select everything in the properties disappears z, so I don't understand where to deny 0?
Thank you.

and sure, where you read everything (6094) you must select the type of entity to read the properties and then you can correct them

I have selected with the mouse of the smaller pieces of the drawing and in this way I see in ownership the z and inside time to time I wrote 0.
Thank you.
