are the layers of the floor all inside the core? Does the column extend to core? Did you join in correct order? These are some of the questions I have.

Yes it is a structural column. And the floor layers are in the correct function. Only the concrete core in the core boindary

...okay, so here's another question; this one regarding the screenshot you posted. Is this Revit or AutoCAD? Reason I ask, is because I don't often see black backgrounds used in Revit.

im not sure why - as you ask..... however if you want it to then simply adjust the Base Offset of the column

@Anonymous - just my two cants - when I gave the base offset of the column a negative \value, it didn't cut through the floor to the structural core. Given a large enough negative value, the bottom of the wall  will stick out of the slab but not cut through the floor (and I had set up a 6" th floor as well as a 6" th Core. I feel the OPs pain.....

@Sahay_R

i think this all might be down to the why? oh why?..... :zwinkerndes_Gesicht:

 

columns are only related to levels. no floors / no cores / only a level - and in fact do not interact with the floor at all. you can place a column anywhere with nothing under it for support or floating 20mm above the floor..... LOL

 

im not sure how revit-structures deals with columns. youd think it would be different eh?!

 

maybe if a column was floor hosted AND had void/cuts it would do the things you both seem to be after?

Well, because Revit doesn't have a VERTICAL extend-to-core type functionality. And lacking that, it thinks you're trying to join the column to the top layer of the floor. And the top layer of the floor is not the same material as the column.

 

To join correctly, you're going to have to model the non-core layer(s) of the floor as a separate floor element, and sketch it AROUND the column base, then stretch the column down to touch the lower floor and join them.

 

OR...

 

If this is only necessary to get a single detail section showing correctly, don't remodel everything, but instead just use the View > Graphics > Cut Profile tool to extend the base of the column through the upper floor layers, and use the Modify > View > Linework tool to get rid of the separation lines between them so they look joined.

@chrisplyler: Why would he necessarily need to model the floor layers separately? Or do I misunderstand you? Seems to me, that if the column base is in contact with the "core" layer of the floor, it would be just a matter of joining the elements together in the correct order.

@barthbradley

 

@chrisplyler is correct.  Columns don't join to a floor the way walls join to walls or columns join to walls.  Below is a structural column before and after attached to the floor.  The column and the core of the floor share the same material.  They are both set to structural.

There are two ways to do that - "Switch Join Order" tool or by "Material for Model Behavior" family parameter:

but i guess you already placed the column under the finish level, @ the slab level? right ?

 

because in my case m i'm placing the column on the floor level, not the slab level, so the column never reaches the slab level what ever i did

Yep, at first, you have to extend column to the core. I believe there is no other way.

No superhuman strength is needed to perform this feat.
