Hi Miriam, I guess the surface is being divided into two few triangles. You can increase the number of triangles by increasing the "vertex density" parameter. To do this, select the surface (ctrl-click it), use inspection selector (menu Actions / Inspect), set the "Inspect" menu in the inspector dialog to MSMS Surface, increase the "vertex density" parameter, say from 2 to 5, and press the Enter key after typing in the new number. That should give a smoother surface. Another step that can improve the lighting of the surface is to enable glossy lighting in the Lighting panel. Menu Tools / Viewing Controls / Lighting, quality -> glossy. Some old graphics cards don't support this.

I am having trouble with some pointed edges to my surface (attached). It only happens in one location - everywhere else the surface is smooth. I appreciate any suggestions.
