Hi @yannickMBA7N
Advance Steel will output whatever you model so from you screenshots the slots are outside of the object in the model and thats how they are showing in the DXF as they are created on the Holes layer
There are 2 ways to get what you want
1. As mentioned in previous replies create the shapes you want using the polygon contour
2. You could open then DXF and trim / remove the bits you dont want
