How to concave a triangular shape

ollie_morrison

I have a softly rounded triangular shape that i am making a microfiber cleaning pad that has a slight concave in it. How do I find the middle of this shape so to add a line in it and revolve remove some of the shape?

The center of an equilateral triangle is at the intersection of its medians. (A median is a line from a corner to the center of the opposing face.) Is this what you're asking?

Yes although I still need to remove revolve a concave of the top surface and it is not working. I have found the middle and have drawn a line down it as a revolve axis but it is not working

What are you hoping to revolve?  You need to have some face or sketch region to revolve about the axis you've made.
