Slanted Columns Cut Plane

[jabarig]

I'm trying to show the proper cut plane for Slanted Concrete Columns in my model. In plan view although everything else (walls, doors etc) shows cut at 4'-0" above the floor the slanted columns are showing the full height of the column. I've gone through every possible setting within and out of the family to get the columns to show properly in plan but nothing works. If I cut them in section the column shows properly so what's going on in plan?

I first thought that it has to do with the Detail Level of the plan drawing. For a wide-flange column, it shows as symbolic lines and shows the location of the placement of the bottom of the column in Coarse detail mode, but shows it slanted in Medium or Fine detail modes.

Then I tried a rectangular concrete column. It shows slanted no matter what the Detail Level for me, so I'm stumped. What family are you using?

It's called "Concrete-Round-Colum.rfa" I got it from the installed Families library under Structural/Columns/Concrete.

Unfortunately if you've used the Slanted Column tool you cant affect the Plan View. Best way is to create the angle in a regular family where you can control that display.

That's what i was afraid of. Thanks dhurtubise.

Actually, those families work correctly in regards to displaying the slanted columns in plan view, being cut by the cut plane.

I'm also a bit surprised about your columns indicating the full length on plan. Could you attach a sample RVT file so we can see how this is happening. No matter what I do I see the same thing as per Alfredo's screen capture - which IMO is correct as it should be. Perhaps I'm missing something or you've got a weird scenario.

They do show the cut properly but you cannot control it.
Say you only want the footprint, which we want, then you cannot.

Exactly! Revit is showing you the true model, not a BS representation.

So you have only a few options: e.g. adjust the view range (at least as a plan region around the column) to 0 relative to the level.

Otherwise, you need to somehow draw something which is not as per the physical model: e.g. hide the column and draw a filled region. This would be my method of choice, since what you're doing is actually misrepresenting the true physical thing, thus drawing linework at places where it doesn't actually exist.

The idea of symbolic lines / detail components in the column family is not going to work in all scenarios (or even most) since they would only display if viewed perpendicular to the column's axis. Which obviously is not going to happen since the column is slanted (thus not perpendicular).

Another idea might be to draw Model Lines in the family and play around with the visibility of the family's objects. But even this might not work, since depending on how the column joins a slab you might only see half the model lines (at best). It's actually worse when you attach the column to something like a slab, since then the "bottom" of the column might be at a totally different place to where you'd expect it to be.

Of course we can. Make a plan region around the column, and change the height of the cut plane of the plan region.
