Problem splitting a stacked wall

KarenLBR — Fri, 14 Jun 2019 16:01:45 GMT

Hello.

I'm working in Revit light 2018.

I have been having a bit of a headache in drawing a house with a stacked wall (low level red brick finish, with a rendered finish above). There is a small single storey extension constructed at the corner of the two storey house. I have been struggling to get the main house to have the primary join, with the extension abutting in a t-junction. Revit seems to want to join the main wall with the extension - which leaves a bit of a hole... Any how, that is by the by. I think I've cracked it.

Or I thought I had, until I then tried to split the wall as we are partially demolishing it (of course, we are demolishing that corner). I split the wall, created a duplicate 'existing' wall at the corner to demolish, and thought all was fine. However. When I check, the low level aspect of the wall appears to have ignored the split and retained the joint - which means that in my new plan, I will have a wall where I'm supposed to have demolished it.

I have checked the wall profile, and it looks correct - straight edged at the split end.

Attached is a .pdf of screenshots of several views (the plan and elevation of the demolition drawings, and the profile of the retained section of wall).

Please can someone let me know if there is a stacked wall setting that relates to junctions that I have missed? If I have waffled and you can't understand my problem do let me know, and I will try to clarify.

Many thanks

This is a hard read. Think you could post the RVT?

Apologies- I was in a bit of a rant mode...

In essence: (referencing project compass points, not true points, as this is how you will look at the file. ((elevations refer to true compass points... so the elevation in question is north west))

All the walls are stacked walls (brick at low level, rendered above).
The southern wall should join the western wall at 90 degrees. Then western extension (single storey) should meet the corner.
To demolish west end of southern wall, I've split the southern wall approximately in the middle.
The low level brick section has ignored the split, and retained the junction, despite the wall profile being correct.

I've attached the Revit - hope it opens ok, and the summary is slightly clearer.

Not sure if related but you have overlapping walls.

Wow. Lot of interrelated issues here. You got anything simpler we can work on for you.

I think @ToanDN hit on the main issue -- lots of overlapping and no embedding (e.g. Joining). Hard to tell what wall condition should take precedence over another. No wonder Revit is floundering. Might be easier to not use Stacked Walls. Break 'em up.

BTW: I didn't take your original post as a rant. It was just hard to connect the dots. A lot was being described.

Easier would be nice, I realise!!! 🙂

Thank you @ToanDN - I thought I had checked and double checked for overlap, but clearly missed this.

However.

To remove the overlapping bit of wall, I've hidden the left hand 'demolition' section of wall, split the full length wall, and deleted the left hand (overlapping) section. But in doing the split, the right hand section has gone weird - almost as though it has duplicated and offset itself...(see attached). Any suggestions why this has happened or what I can do about it? Or is my best bet complete removal and re-draw of this section of wall (including windows... sob, sob)

I'm not sure which condition you are trying to resolve. There are a bunch of them. Is it this one where the walls are not in alignment with each other?

@KarenLBR : My advice would be what I mentioned above: DON'T DO STACKED WALLS. You have numerous errors/warning/conditions that involve stacked walls. I'd break 'em up to make 'em more manageable.

Also, I'd focus on resolving the Wall Warnings you have regarding the "Overlapping Walls".

Thank you for reminding me to check my warnings @barthbradley , though I'm slightly bemused by the image you have included in your post, as I don't have any curtain walls in this model! (So if Revit thinks there are... hmmm).

The issue I was trying to resolve appeared when I split the stacked wall (and the wall appeared to duplicate and offset itself) - though I don't know which warning it was specifically. I have resolved that particular issue by copying the wall in from an earlier version, but reducing the length rather than splitting it.

Do you think this is a glitch with stacked walls generally? You presumably would recommend drawing each strata of the stacked wall individually, one on top of the other? Would you then embed them or join them?

As it happens, I may have to abandon this one anyway as I need to draw a curved curtain wall but can't in Revit light. 😞

Many thanks for your patience and assistance on this!
