Use the FLATTEN command. You must have Express Tools installed. ------------- "Humans have a strength that cannot be measured. This is John Connor. If you are reading this, you are the resistance." <<AutoCAD 2015>> |

| That depends on what you mean by objects [considering also the possibility of things other than Lines] being stretched on the Z axis. If, when you select a Line, the Properties box shows a "Delta Z" value of zero, but it's "tall" into the Z direction when viewed from a direction other than plan view, then it must have non-zero Thickness [not to be confused with Lineweight, or with Width in Polylines -- Thickness is "up off the page" in the Z direction]. Other entity types show it differently than the Delta Z value for Lines, but like Lines, they will all have a non-zero value in the Thickness slot in the Properties box. FLATTEN is not needed to fix that [though it will] -- just change their Thickness to 0, either in the Properties box or with the CHPROP command, to flatten that kind of extension in the Z direction. And unlike Flatten, this approach will leave things that should remain at different elevations [such as contour lines] where they are, instead of taking them all to the 0 level in the Z direction. |

Hello everybody, I have this old method working on all the AutoCAD releases ( I suppose ).
With an UCS set on WORLD: move all the objects from point 0,0 to 0,0,1E99 then move all the objects from 0,0,1E99 to 0,0,0.
this should be checked with a 3D viewpoint that you find in : View, 3D point of view, SE or an other.
Amaona, please tell us what you have done, succeeded or not, etc...

[That will "zero out" the Z coordinates of things, but will not change entity Thickness, if that's the issue, to zero. The Flatten command will do both, if that's what's needed.]
