Contour scale different (X, Y, Z)

[villelamatheeus97]

Hello, everyone!

I made a mapping flight using a drone and generated some information, such as contour lines.

Opening the contour file in GIS software, the scale between the X, Y and Z axes is correct. However, opening the DWG file in the CAD software, the scale on the X, Y and Z axes changes.

The Z plane remains with a vertical equidistance of 1 meter, but the X and Y axes appear with strange millimeter scales, as if in the process the meters were transformed into millimeters. The contours assume an absurd distance on the Z axis, as if they were much further away from each other. 

How to fix this problem? Are there any settings that can be made so that the X, Y and Z axes are scaled correctly?

Thank you, everyone.

What's the GIS software exactly?
What variant of AutoCAD are you using?

Hi @villelamatheeus97,
Welcome to the Autodesk Forums.
Hard to tell from your screen shot. Can you zip together and post your drawing and data? And as @pendean requested it would be good to know what other software you're using and what version of AutoCAD.

ArcGIS and QGIS. Working well.

Actually using AutoCAD 2018.
