hatch walls under the floor

Is it possible to give walls underneath a level a different hatch then the (same type) walls above?

The walls above a floor would most likely be cut by the view, and therefore the "cut pattern" would be used for display. the walls below the floor would not be cut, and therefore the "surface pattern" would be used for the display.

These attributes can be set using the "object styles" dialog (), or using the Visibility/Graphics overrides ("VG" while in the view, or from the "properties" dialog of the view, select "Visibility/Graphics overrides") (this probably makes more sense)

However, the slab (floor) would be blocking the visibility of the walls below. You could turn off visibility of floors in the view, or you could (if you're using r2008) use element visibility overrides to turn the floor transparent (select the floor, right click>override graphics in view>By Element>Check "transparent" in the top right of the dialog) This will mess up the default hidden lines view in Structure.- the walls below will no longer be shown as hidden, but you could change the projection linetype of the walls to be hidden.....

Also note that this is in medium and fine view. Walls can have a different cut pattern for "coarse view", which is in the type properties of the wall.

So, the answer is "Yes."

Are you confused yet?

Wow, that's a lot of information. But let me explaine a little bit more, just to be sure. I added an example of what I mean. It's made in acad and thats our system how we draw in acad. The amount of information we put in our dwg drawings, should be in the new Revit drawings. That's what I'm investigating. One part the information is hatching above and under floors, just like the example. I tried all the options you out, but they are (I think) not working. But I'm pretty new with Revit, so maybe I have to try a bit harder. Can you confirm that its possible to make the hatch different under the floor like the example?

I checked, and everything I told you works, even though it is a hack.

As a hack, there are situations where the picture is not really what you want- i.e. by making the floor transparent and changing all "Projection lines" of objects to "hidden", you essentially break Revit's automatic hidden creation.
(See the attached image)

If you are serious about making the move to Revit, I would suggest revisiting your graphical standard. In the Object styles dialog, you can set the "Hidden line" style for objects (say, walls and beams) differently, so that you can differentiate them on your plan. That may satisfy the "intent" of your graphical standard, even though it is not what you currently do.

You may want to ask yourself- does this beat drawing and hatching all this manually? Is what I may have to sacrifice in some control of the output worth the time I save in drawing every line individually? Because Revit tries to do it all for you automatically, you'll never have the kind of control you do in AutoCAD, because every object is made of multiple line segments and hatches (which you have to manually create).

Maybe someone else has another way to do this- anyone want to chime in?

Anyway, this is all my opinion... Hope it helps.

if the walls are different types, the components of each wall can be
assigned different materials to display different cut patterns.

if the walls are the same type, in 2008, an override can be assigned (just
select the walls you want different, right click, and fine 'override
graphics in view') to display different cut patterns and linetypes.

or you might use a filter to display different cut patterns and linetypes.

You should be able to use a filter to select walls by level, and assign a hatching to ALL walls on that level, regardless of materials. You could get more adventurous, and use a filter for each material of wall.

Right, you can assign a hatch (or pattern) to anything based on a number of criteria, but getting it to display is another story.

"Hatches" in Revit are not independant objects, but display properties of objects.

Revit displays these (generally) in two ways: When an object is "cut" by a view (cut pattern) and when the surface of an object is visible in a view (projection pattern)

The problem for this user is that the surfaces of a wall below the floor are not visible, because the floor is in the way. Therefore, no surface patterns will be visible.
