ac10 walls

[Anonymous]

walls in ac10:
home storey of wall starts at level 0.00 and ends at +2.50
wall base is at -0.05 and wall top is at +5.00.
when I select "show on / link to storey" - "own storey only" instead of the default "automatic" value the wall dissapears from the plan view. 3D is ok.

what should I do? I think I tried all the combinations with "floor plan display" and "projection" but the result is the same.

Have you checked the story below? The "automatic" setting means that AC determines the wall's home story based on the base level. Your setting will make the story below its home story, thus it should remain visible there, at least if you firts change the display setting to "Symbolic cut"

the automatic setting is working fine.
the problem is with the home storey option that should show the wall only on the storey on wich it was created. instead it disappears. it is true that the wall has the base below the home storey and the top above it, but this is a necessity in this case.
this setting should allow the wall to behave like in previous versions.
am i missing something or in's a bug?

I could be wrong, but I think even with the "home story" setting, the Home Story is the story that contains the walls base line, even if it is drawn while another story is open.

It really should, but...

Aha. A wall set to 'automatic' has no home story. Strange but true. If you switch a wall from 'automatic' to 'own story only', it has to choose a home story, and to do this it uses the elevation of the base. It doesn't remember the story that it was created on. This can cause the wall to vanish from the current story and appear below in your case.

My policy is to use 'own story' as default for this exact reason. Only use automatic as needed.

Draw the wall with 'own story', and then leave it alone.

It does seem to lose it's reference. I just tried to change the height of a window on story 1 where the wall extends from story -1. The window dialog would not reference story 1 anymore. It only referenced story2. The wall does not extend into story 2 so the window would not behave.

Odd.

Hi

I have been investigating this topic and I think the confusion is two-fold:

1. The difference between creating a new wall and editing an existing wall.
2. The difference between using the 'Automatic' and 'Own Story Only' settings for single-story walls and multi-story walls.

1. The thing to note is that when creating a wall the 'Show On/Link to Stories' setting appears as 'Current Story Only' (if it's not set to 'Automatic'). When editing an existing wall, this setting appears as 'Own Story Only'.

If we create a wall with the 'Current Story Only' setting, it will only show on the current story regardless of it's elevation. If we edit that wall and change it to 'Automatic' and then to 'Own Story Only' it will go from the current story to it's own story. According to GS terminology that story is based on 'the current vertical position of its reference line', which for a wall is located at it's base. This is probably best demonstrated by trying to model a wall on an upper story, whose base elevation is on a lower story, because if the vertical position of the wall's base does not lie within the current story, a pop-up warning may appear (if it hasn't been disabled) telling us the wall will appear on an unseen story.

I emphasize may because it then depends on the type of wall you are dealing with - a single story wall or a multi-story wall.

2. If we create a single-story wall using 'Current Story only' it will appear only on that story (even if the wall has a base elevation that is not on the current story). This is the default behavior in ArchiCAD 9 and earlier, so one might be inclined to use this setting for typical single-story walls and ease the transition into AC10. Incidentally, if we later change it to Automatic, it will move to it's correct story, based on the vertical position of the reference line, which we now know is the wall base. Again a pop-up warning may appear telling us the wall will appear on an unseen story.

However if we create a multi-story wall using 'Current story only' it will only show on that story. This may not be desirable since it won't show up on any other story it enters. But if we create a multi-story wall using 'Automatic' it will do two things: Firstly it will go to the correct story the instant it is created, again based on the vertical position of the reference line - the wall base. And if no part of it is seen on the current story, the pop-up warning will again appear telling us the wall will appear on an unseen story. Secondly it will appear on any other story that it enters. Now that depends on the 'Floor Plan Display' settings for that wall and the cut plane height of each story, but that's another story (pardon the pun) and potentially takes the confusion to three-fold or four-fold!

FWIW it's my opinion that the most logical default wall setting for AC10 is to set all walls to Automatic. This is the default setting for walls in the standard Graphisoft templates. It's not as easy to get used to, but if you want to 'dive right in' to AC10's new features, it'll take a while to adjust, but I think it'll be worth it. My reasoning is because if the Current Story Only setting is used, it is too easy to put walls on the wrong story. Sure this was handy in AC9 sometimes, but not so much now because of the new multi-story walls in AC10. Also because all walls will go to the correct story the instant they are created and multi-story walls will show on every story they enter. It's also consistent with creating walls in 3D.

There'll always be times when we need to set certain walls differently, but unless I receive information suggesting otherwise, I will be recommending Automatic as the way to go for general modeling.

Just my 2 cents...

Gotta be worth at least 10cents, surely.

. . . and now for your next challenge . . . if you're up to it

work out the best method for displaying roofs. to auto or not to auto. particularly when using accessory tools to clad them with and they're pitching at about 6º through the top of storey 1 and the bottom of storey 2 . . . . ( )

your time starts . . . now...

Sorry mate - I was fishing down at the river fishing, trying to catch dinner (lucky we have tinned tuna in the cupboard).

But for the Roof tool.... It has a Custom setting instead of Automatic. Takes care of all that stuff. Love that consistency...
