Merging coincident solid geometry

User: "Alex_22223"

I have two separate solid geometry parts that have coplanar surfaces.  How can I merge the two solids together into one part?

My goal is to create 2D midsurface geometry from these solids.  If I do that with unconnected solids the resulting midsurfaces are also not connected.  If there's a way to do this without merging the solid geometry I'd be interested in learning that too.

    Have you tried with Geom-->Solid Edit--> Merge?

    That doesn't work unless the solids share the same surface.

    Another method without merge: split the upper surface of the 2nd solid by edges of the 1st solid. Make the mesh for 2nd firstly. The mesh of the 1st solid will be created from "drag" element face from the 1st.

    For mid-surface extraction, do it for two solids and extend the surface to fit.

    After mid-surface extraction, we have two surfaces:

    Geom > surface edit > extend

    Finally we get connected surfaces!
