|Tiêu đề: Extending Walls - Wall Layers in Revit 5/4/2013, 19:04|| |
Walls - Wall Layers in Revit
it or not, Revit will allow you to extend or contract selected wall layers above
or below their base or top constraints!
means that you can have one part of the wall assembly at a different height to
the rest of the same wall. Let me demonstrate:
by creating a couple of
Basic Walls, I have used a Double Brick wall that came with the default
template. These have a few layers already so they should do the trick.
one instance of this wall type and then go
into it's properties, now click
'Edit/New' to bring up the
the 'Edit...' button to
bring up the Wall Assembly editor
sure the Preview is open and that the View is set to Section in the drop-down
in (using the scroll-wheel on your mouse) to the bottom of the wall and click the 'Modify'
Now click on a line at the bottom of
your wall assembly. You will notice a small Lock appears. Clicking
the Lock to unlock the
layer is how we will define which layers will be extended. You can do this to
the top of your wall layers as well.
OK, then OK again in the
Type Properties dialogue.
will now notice a new Instance Parameter called 'Base Extension Distance'. This
parameter will extend the 'Unlocked' layers a positive (up) or negative (down)
value. If you unlocked the tops of any of the layers, you will also see a Top Extension Distance.
have set the Base Extension Distance of this wall to -500 and the parallel wall
to -200, then cut a section through. Note how the unlocked layers have moved
down while the others stay at their base constraint.
can also unlock the adjacent layer in the Wall Assembly, note that you can only unlock adjacent
layers. To do anything more complex, you will need to use Stacked
Walls. Notice that both unlocked layers now move with the Base Extension
Distance. That is, there is only one Base Extension Distance parameter per wall
Base Extension will work with the Base Offset parameter. In the above picture I
have set Base Offset to -200 and Base Extension Distance to -500. As you can see
(more clearly), this wall has the two outermost layers unlocked.
