@francelic7 ,

Welcome to the forum.

Try converting it to 3D solids first.

Also keep the following in mind:

Perhaps  your model is not watertight. Could you post your DWG file here?

[francelic7]

Sure, here it is

I tryed that but it didnt work. 😞

I ran your model through a program that checks for water tightness and your model has holes.  It also has many triangle edges which are shared with 3 or more faces, which should not be.  Sorry but I do not have program that will fix  these problems.  My version of AutoCAD does not have  STL import/export capability, so I can't tell you if that is your problem.

Are you going to 3D print this model?  I loaded it into my slicer program and there were no errors reported, so it may print with no problem.  You do realize that your model is only about 2mm square?

@francelic7 ,

You have to make sure the objects are watertight or have no gap between surfaces.

Consider using the menu "Modify" > "Mesh Editing" > "Convert to Faceted Surface" to convert 3D Faces to Surfaces;

then use menu "Modify" > "Surface Editing" > "Sculpt" to convert those Surfaces into solid.

Be patience, since these operations take some time to complete.
