SEM image to 3D structure?

Hi @mrinmoy
After you have created your structure. Please follow the instructions:
1)Select your object and click right
2)Edit object–> Click tab “Rotations”–> First axis: x --> rotation 1 (degrees) : 90


Dear @mrinmoy

You can add hemisphere from Object Library. As @konslekk mentioned, this object has a 90 degree rotation around y-axis which can be viewed from Edit–>Rotations tab by right clicking on the object.

If you set the rotation to be along -90 degree around z-axis, you can have a hemisphere as below:

And here is an screenshot of the Rotations tab:

I hope this was helpful.
