Question 1:
From Autodesk Revit Help:



Allowing Layer Extension

If you select the horizontal outer boundary at the top or bottom of a layer, you can change whether that layer can be extended or not.

Select a horizontal boundary at the top of the layer, and a padlock appears. A locked padlock indicates the layer cannot be extended. Click the padlock to unlock it, and the layer can be extended.


Unlocked layers must be adjacent. You cannot have one layer locked and its adjacent layer unlocked.

When you unlock layers for extension, two instance properties of the wall become enabled: Top extension distance (for layers at the top of the wall) or Bottom extension distance (for layers at the bottom of the wall). You can type values for these properties, or you can drag the unlocked wall layers in a view.

To drag the wall layers, you can modify them in section, 3D, and elevation views.


Place your pointer at the top or bottom of the wall in section and press TAB to prehighlight the shape handle for the extendable layers. Watch the Status Bar to be sure you are prehighlighting the shape handle.
Click to select the shape handle.
Drag the shape handle up or down.
All of the above is done by selecting walls>properties>edit/new>edit>preview>view section.
Question 2
Yes, but then all layers will move together.
Question 3
I'm not clear on what you're asking here.
Question 4
You can attach a profile to a wall by sweeps in the walls > properties > edit/new > edit > preview > view section. Be sure to load and/or create the profile you want beforehand.

Question 5
See above.

Question 4: Could you recommend method to create brick shelf in conc. fdn. wall?I've found it easiest to do a host sweep at the edge of slab -- then join that geometry to the foundation wall at the detail level.


Question 5: Why is shape handle for insul/airspace editable but cmu/brick are not?Shot in the dark on this one: Perhaps Revit "understands" the difference between 'solid material' and 'flexible space?'

A method that I find works well is the following:

If you have a 12" foundation wall with a 4" brick shelf, create the wall with one 8" layer of concrete and one 4" layer of concrete.

You can then unlock the top of the 4" layer, and lower it either by dragging it or via the properties dialog.

Very nice tip Andrew. Simple to do and retains the parametric qualities of the wall. This would be a good one for the FAQ forum and / or Tips & Tricks.

Thanks Robert.

There is one caveat, and that is when the wall is cut in section and viewed in medium or fine detail, the border between the two concrete layers show, & the linework tool won't eradicate it.

The way I get around that is to place foundation walls in their own (previous) phase, and that clears the problem.

How so? (Haven't had a project that used phasing yet.) Overriding the settings for that phase?

[aggockel50321]

If you use the default Revit template phasing, two phases are set up, "new construction" and "existing".

All the views default to new construction, & thus, anything created or placed, ends up in the new construction phase.

If you select all the foundation walls, go to properties and move them back to "existing" , or, in settings, create a new phase(ed: before new phase) called "foundation" & place them there.

Then, assuming your section view is set to new construction, with the filter set to "show all", the walls will grey out & no longer show a cut fill. If you don't want to use the grey (thinner) lines that show for previous phase stuff, you can go into settings/phases, graphic overide tab, and change them to match the current phase.

The other nice thing about this approach is that you can create or duplicate a 3d view, set the phase to match your foundation walls, and you get a 3d foundation plan, which makes it easier to study where you want brick shelves to begin & end.

Thanks for the clarification Andrew. Do you also use the foundation phase to create your foundation plan drawing as well by putting basement columns, windows, window wells, etc. in the same phase, or is it mostly a working method used to aid in the modeling stages? I ask because Aaron Rumple has recommended using worksets as a way to be able to view the foundation from the top without having the first floor walls and other model objects show up. It seems like using your phasing methodology might offer similar benefits. I would guess that either method could be made to work but that each probably has its own pros & cons.

I'll put any items needed to construct the foundation into that phase.

If you don't want to deal with the overhead associated with workgroups, phasing (with some custom filters) is another way to split up a project.

Great. Thanks.

That's what I thought, except that I am a bit confused with the Revit's naming (or coincidental naming) of the phases and the phase filters. For instance, default REVIT phases are: "New", "Exist", "Demo" and "Temp" (or some variations of it) but I wanted (for some reason) to place a retaining wall in its own phase (resolutely called "Retaining Wall") and so I created a new phase (between "Exist" and "New"). But when I went to filters I didn't see my phase "Retaining Wall" - only "New", "Existing", "Demolished" and "Temporary", with no chance to create my new (custom) filter. Sorry, I am dumb - I know, but how do I should go through this confusion? It would be a such fantastic way to place some elements in their own phases and "turn" them "on" and "off" as required.

I think you've got the filters confused with phases. Phases aren't the best way to control the visibility of items in a view. It is a method of seeing objects created at or before a view's current phase. So in the case of the foundation, discussed above, it works well.

The default phases Revit creates are New Construction and
Existing (go to settings/phases, phase tab).

In the phase filter section (phase filter tab), the filters are new, existing, demolished, and temporary. These are the states of any object within the view.

Explaining filters gets confusing, but once you see how they operate, you can figure out ways to get certain objects to show in a view, based on their state.

Here's a try:
New filter pertains to any object created in the current phase of the view. Existng filter pertains to any object created before the current phase of the view. Demolished filter pertains to any object created in a phase before the current phase of the view, but demolished in the current view's phase. Temporary filter pertains to any item created then demolished in the current view's phase.

Hope this helps...

Thank you,

Yes, it clarifies somewhat the difference for me.

However, I still think, that if there was a flexibility to make up your own (new) filters and just specify what phase or phases you want to see (ie. filter named "Retaining Wall" would turn "on" only the phase called "Retaining Wall"), it could be a very powerful tool for precisely what I was thinking - turning "on" and "off" various objects.

Thank you anyway,

Phaseing should be used for phasing - not visibility control. Otherwise when you do end up needing phasing, you have a mess on your hand. Everything I've wanted or needed to do for visibility control can be done with View Graphics, Design Option, Worksets, Crop Regions...

...except for those pesky elevation symbols.
