Civil Geometry Manipulators - Civil Accudraw and Snap Input

The inputs from Civil Accudraw can be persisted onto the intelligence of the geometry elements.  You must lock BOTH Civil Accudraw ordinates and then the input from Accudraw is automatically persisted onto the point.

In the following video:

1. I have a simple line which I use Civil Accudraw to lock station and offset inputs to define a second line (green)
   1. I keyin and lock both station and offset when set the beginning of the green line
   2. Then I simply lock (without keyin) the endpoints of the green line.
2. Then I create a third line
   1. I snap the beginning of the third line
   2. The end point of this third line is set by Civil Accudraw distance and direction by locking both.
3. Then I select the original red line and drag the midpoint handle.
   1. Notice that the Civil Accudraw station-offset constraints are dynamically updated as I do this
   2. Notice that the snap constraint of the third line is also maintained.
   3. Not as noticable is that the end point of the third line is maintained at the distance and direction created by Civil Accudraw.
4. Then I select the 2nd line and edit the Civil Accudraw constraints by click on the text and key in new values.
5. Then I select the thrid line
   1. Notice that there is a snap icon at the beginning point where I snapped.  This tells me that a snap is persisted here
   2. When I move my cursor close to this end, the snap icon is replaced with the normal drag handles.  I could grab one of the handles which would replace the snap constraint with whatever I do while dragging.  The Civil Accudraw constraints can be similarly removed/replaced.  Move the cursor close to the point where Accudraw has been used and the drag handles will appear.
6. Finally, I edit the distance and direction inputs persisted from Accudraw onto the end of the thrid line.
