# Creating a isocontour surface

An other way to visualise the electrostatics grid are isocontour surfaces which connect all neighbouring points in the grid which have the same electrostatic value.

We will now create such a isocontour surface: First find the Datasets widget, then highlight the FDPB dataset and use its context menu or the menu entry Tools ⇒ Grids ⇒ Render Contour Surface to create the surface.

In the now open dialog enter the value 0.01 as threshold and press OK. It also possible to create multiple iso surface with different colors.
