For hatches to appear in your elevations, it needs to be in a renderworks texture, and that texture is then applied to your wall.
First step is to have a renderworks texture, click on the edit option(you're in resource manager window),
you can choose hatch (instead of none) and then on the bottom, you can choose your preferred hatch.
(in resource manager) you can modify your hatch scale by right click/ edit, try to find the scale option.
hope this helps.
