What line type do you use for overhead "stuff"?

Anonymous — Fri, 07 Feb 2025 13:56:25 GMT

I'm wondering what the proper line type is for showing overhead things, like the upper cabinets in a kitchen. Do you use the dot & dash or the double dash? I personally use the double dash, but my office differs on the subject. Not exactly ArchiCAD related but...

Personally I see Double Dashed as more of a centreline ( ____ _ ____ _ ____ ), and use Triple Dashed ( _____ _ _ _____ _ _ _____ ) for overhead lines, particularly roof overhangs and the like. Something like joinery might require a smaller dash though.

Hi Steven
My first checkpoint would be the local drafting standards as these usually have recommendations for stuff above and below and how to represent it. I think the Australian standards say long dash for overhead short dash for things below but hidden. I'm sure someone will correct me if this is not right.

Double dashed lines for everything above. Two diferent double dashed lines - large for structural elements and smaller for furniture.

This is also the [American] National CAD Standard, and what we've adopted for our office.

Here the below hidden lines are dotted.

That's the standard here in Canada too. Lots of firms here are adopting the AIA National CAD standards.

Same convention I've used for years (decades really).

However, under Preferences>Construction Elements; GS has the 'Above Home Story' & 'Below Home Story' lines reversed from what actually shows on the plan (I have a plan out right now and just tested it again in 12). To be helpful, be careful when setting project preferences.

I've seen this Line/language reversal in every version since v5.

[It is not reversed in the reversed Graphisoft thinking kind of way.]

'Above Home Story' means the object-centric
the lines that elements will show on floor plans above the element's home story (the element placement story, that sort of is)

and not the viewpoint-centric and therefore more intuitive —at least for people, maybe not for construction elements—, especially when you are dealing with project preferences and not object settings
the lines that elements will show when placed on and projecting from stories above the current story (the floor plan you are looking at)
