Architectural sections are typically different from strict planar sections.
There may be no single plane which captures all of the post/brace/window-framing,
Elements may be aggregated from several parallel planes to generate a
I've been monkeying with a completed model and generating a satisfactory section
is proving more challenging than I expected....
Using a section plane eliminates the "foreground" entities OK, but all the "background" stuff is still there.
So I just create a white plane to drop behind the section plane.
There are still lots of both missing and extraneous items.
When doing the floor plans, I resorted to creating FP_ON and FP_OFF layers to put model geometry in
which would be selectively shown/hidden depending on the view one wanted.
Now, adding another orthogonal "layer" of selective hiding has me head-scratching
I am considering creating groups of items which are unrelated except by the need to show/hide them when doing composite sections.
Another tack would be to copy single-instances of all the required geometry to a new location
but that seems kludgey as hell - any model-changes would require changes to the secondary-"section"-model
This is such a standard "thing" that someone must have worked out a simple rigorous effective solution.
In the 2D drafting world, the exclusion/inclusion of geometry was implicitly done on the basis of the particular drawing-view... how to deal with this ?.
