# Floor Plan Cut Plane and Story Settings

Anonymous
Not applicable
Hello,
I am having some difficulty understanding
the logic of the floor plan display in AC 10.

I draw a wall 8'-0" high with it's base
at at 0'-0" from story one.
I set the floor plan cut plane height
to 9'-0" from story one.
If I set the "height to next" in the
story settings to 7'-6" then the wall
contours show as cut lines
If I change the "height to next" to 8'-6"
then the wall contours show as uncut lines.

I am unclear about what the height to next
has to do with how a wall is shown as
cut or uncut by the floor plan cut plane.

Perhaps someone could explain this.
Thank you,
Peter Devlin

Peter,

In "Floor Plan Cut Plane Settings" dialogue, under "Floor Plan Range", either set "show up to:" greater than 1 OR set "Offset By:"=1' 7".

Hello LiHigh,
I did your first option of setting floor plan range to 2 but
nothing changed. Obviously, I must also change something else
as well. I left every thing else exactly as I last had it except
to change the eight foot wall back to "Automatic" in order
In your secound option, what is the derivation of the figure 1'-7" ?
Thank you,

And I doubt it will because it's the Cut Plane Height that really matters, not the range.

Peter,

Same senario as you first mentioned. 8'-6" wall, FPCP Height=9',
"Height to Next"=7'-6"

let say OS=Offset by; SUT=Show up to n story above (0=current story).

In Order to solve your Problem, Do either one of the following:
Under Relative Floor Plan Range,
1) If SUT=0 then set SUT=FPCP height (in fact it will be done automatically)
2) if SUT=1 AND Height_to_next< FPCP then SUT=FPCP-Height_to_next

sure it will works!

What seems logical and solved the problem is depicted
in the attached image.

Since all of the walls and openings except one are
at a "normal" height, setting the cut plane to 6'-0"
and the height to next to what it should be,
namely 9'-0" which is the height of the second floor
slab, is the logical set up.

The 2'-0" wall 10'-0" above ground with the arch-head
opening is a special case which requires "taking liberties"
with the plan cut height. Archicad allows this if
this one wall is set to "symbolic cut" which lets
it be seen in the same story as all the other walls
and openings in this story.

I'm sure the math works, but it's the height of the cut plane that determines the wall's cut appearance, unless it's set to Symbolic as Peter concluded.

By all means if there's more to it, please do shows us!

IMHO, walls bodies that run thru story line shall be set to automatic. The reason is simple. These walls would most likely need to be shown on both current story and story above.

Peter, you can also achieve the same result by setting the 8' wall to symbolic and 2' wall 10' above to automatic. It works here (AC10 1010).

If it doesn't works, send me the PLN file. I'll have a look....

Yes, what you suggest does work but what I finally came up with also works, and in this context I don't want to see the high wall on the next story up.
Does what I finally came up with seem non-logical to you ?
Thank you,
