Have any of you every tried to do this in Dynamo with an ordinate dimension strand? (see below)
Ordinate Dimension “Flip Side”
Apparently, the Revit API does not have this functionality - at least not yet that I know of.
Thankfully, there is a nice alternative that makes this function unnecessary. The answer was so simple that it annoyed me and it worked on both axes.
Try plugging in the Curve.Reverse node before the line input on your dimension node and see what happens!
Have a nice day.
