random change of Z coordinate
Vic Phillips 19 May 2020
I am a 30 year+ user of AutoCAD, and recently DL'ed nanoCAD Free for occasional home use, in making simple 2D plans for woodworking projects. It's very familiar in most respects, but I I have run into a problem that is causing much trouble. It seems that random drawing objects will change the Z coordinate by a huge factor, for no apparent reason. It just isn't possible to do this in error, or unknowingly. As close as I can determine, it happens most frequently with closed polylines created with the RECTANGLE command. I am on the World UCS ins Model space, and no matter how carefully I create these rectangles, confirming that all vertices are on "0" elevation, if I copy, rotate or simply move the rectangle, the Z coordinate will change, by as much as 4000 dwg units. This also happens more randomly with single lines, and only on one endpoint. With any drawing element, If I access the properties and manually change the elevation back to "0," the whole object just disappears.
Is the installation corrupted? Is there some bug? Any help would be welcome!

This one. Simple 2d layout, for my build use, not for presentation.

Hello Vic,
Sorry, not possible to reproduce the bug on my computer .
Idon't see where is the bug
When this problem occurs, a regeneration of the drawing gives what
A file with objects that have changed Z?
to see if this change is saved and if it allows me to see this problem: "If I access the properties and manually change the elevation back to "0," the whole object just disappears."
Best regards
Patrick

Nothing happens when I regen. This issue is not happening accidentally; it takes a bit of effort to change Z coordinates.

Hello,
When I look at the drawing in 3D (shift+mouse wheel), indeed there are entities in many Z.
So when we draw with rectangles, polyline, circles and hang on an object with a Z, it is positioned on the Z of the clicked object. This is normal. A polyline stalls on the starting z. A single line can "navigate" through the Z.
But why Z in this drawing? often this happens when drawing using a file that already has Z's like a topographer's drawing, for example.
When it is the case it is necessary to flatten the drawing to avoid being "polluted" his work by unwanted Z.
Does this happen in a new blank file?
cordially

To flatten the drawing simply, select the entire drawing and in the properties, filter the object types then set the Z or the elevations to 0
