If you drag its blue arrow instead of setting a value in the text box, then the "expression" property is the one from <EM>immediately before</EM> it was dragged to its new position. The "value" property returns the correct result in centimeters, so it's easy to work around, just posting in case anyone runs into the same issue.</P><P>Example:</P><PRE># Not working ( last value is used ) distance = adsk.core.ValueInput.createByReal(unitsMgr.evaluateExpression(input.expression, "cm")) # Works distance = adsk.core.ValueInput.createByReal(input.value)</PRE> Sun, 23 Feb 2020 19:28:03 GMT https://forums.autodesk.com/t5/fusion-api-and-scripts-forum/distancevaluecommandinput-s-quot-expression-quot-doesn-t-update/m-p/9336448#M12621 Anonymous 2020-02-23T19:28:03Z https://forums.autodesk.com/t5/fusion-api-and-scripts-forum/distancevaluecommandinput-s-quot-expression-quot-doesn-t-update/m-p/9644768#M12622 <P>I experienced this too.
