when sketching in a part in an assembly, the list of available sketch constraints does not always build until I deselect one of the selected items and re-select it. IE, insert a new part in an assembly and sketch a line. control select the line and an existing model edge OR select "add constraints" an select the same line and edge. The list showing colinear, parallel,etc does not appear. deselect the edge and reselect it. Now the list builds appropriately. SW 2020 sp4.0
