My first attempt at C# for Revit: I would like to recreate the MTP command (Locates the midpoint between two points) from AutoCAD into Revit. The command functions by entering MTP and then the user selects a first point then a second point. Then the start point of a line is created midway between the two selected points. So my question begins with, is this even possible? The next question is would this also be possible within the sketch mode?
