In my previous post I described how top rail / handrail terminations in Revit are not visible in plan, thus rendering them useless for 2d documentation. They have another 'feature' that makes them unreliable for use in any model:
Unreliable Rail Extension LengthWhen you first define a new railing type, with a top rail that has a termination and extensions, the termination goes outside the length of the extensions:
Of course you can't see the extensions (unless you select the railings) - but the rail just looks shorter.
This has been acknowledged by Autodesk as a bug, so no doubt it will be fixed in due course. Let us hope that they also fix the visibility issue, which is not yet acknowledged as a bug - last I heard it was "As Designed".
Possible WorkaroundIf you really want to use terminations, and don't mind about the plan visibility issue, there is a workaround to the extension length issue:
- Go to a section view and select the top rail
- Make sure you get the top rail by Tab-Select, otherwise you'll get the whole railing
- Click on Edit Rail in the ribbon
- The extension line will show blue, but note that the termnation has already moved
- Edit Path (note the Edit Rail Path is different from normal Edit Path)
- The extension sketch lines are now editable - drag the extension sketch line to exactly where you want it
- When you finish editing, the termination will be where you want it to be, and will not move without your permission
- While you are editing the extension path, you could have a bit of fun, and curve the extension line. Antonio Gaudi would be proud of you
- Or you could go really crazy
- But even Gaudi wouldn't like this result as his designs were always very considered even when looking arbitrary

Dimensioning TerminationsAnother issue:
You cannot dimension terminations in section (or plan, obviously), which is a limitation for serious documentation.
Perhaps you could create a detail view and place a separate termination component that is invisible in all other views? Another nasty workaround - but what else can we do?
