Under settings>fill patterns> you create you patterns there. You will click the drafting version>then custom>browse to the revit.pat file or any .pat file you want and then once you select your concrete pat, you can scale it up or down with the scale value.
Note that drafting patterns scale automaticaly per view and model patterns are real world sizes allways. Use model patterns for your surface patterns typically and drafting for your cut patterns.
To change the line types, you pick the hatch, click edit, then highlight the line youwnat to change and select the linetype you wnat it in the pull down menu.
