Change Units After Entering Loading Functions

One issue that I have encountered is that if I go into the load function and realize that I have the wrong units specified, I cannot change the units by going back to the geometry menus and selecting the correct units to use. When I enter the loading menus again, the units have not changed. Is there another way to change the units once you enter the loading functions?

From the Edit menu, choose Edit Input Command File. Scroll down till you see commands like

LOAD 1

or

LOAD 2

Prior to the load case which has the units error, add the appropriate unit as shown

UNIT POUND FEET

For example

UNIT KIP FEET
LOAD 1
SELF Y -1.0
MEMBER LOAD
1 TO 25 UNI GY -0.2
UNIT POUND
LOAD 2
JOINT LOAD
33 FX 400
UNIT KNS METER
LOAD 3
MEMBER LOAD
45 UNI GY -3.0
