how do i edit a path for a solid sweep
that starts on the first level work plane
and spirals up like a coil spring to higher
levels? something like spiral stairs..
or if i could get model lines that way
maybe i could pick that as a path?
there was once an answer here about "piecing"
together parts of the spring and building it up
or something- but i cannot imagine that..
revit 2011- thanks..

Swept blend. I would draw a 180 degree arc for you path, and a rectangle for profile one and ground level, 2nd rectangle at X height. rotate and stack these as you please, and then use an outside edge of these objects as the picked 3D edge path of your more complex sweep.
That's just a first instinct idea, by no means the best idea I'm sure.
to expand on this: It's probably better to do in two steps because it's difficult to account for the disortion of a swept blend between the two profiles. A sweep is always perpendicular to the path however. Swept blend profiles are vertical.

posted pic. easy and fast. Tip: sometimes picking a path will give you an error. Like stairs, shorten it, finish it, re-edit and make it more complex and the program won't complain.
edit: sorry, images are refusing to upload.

i sure did get this thing tangled up in
my mind before i figured it out..
i guess that's why it's taken me five
years to learn only half of revit.. oh well..
thanks alterego

this is when i wish i knew 3d max, a double helix is easy in it, so you could model in max then import to revit...

no if you imported from 3ds max it would have to be
a DWG into a mass.. and the only thing you can
do with a DWG mass is use it for reference- preferably
in a separate session of revit.. none of these programs
can talk to each other.. 3ds and AutoCAD never even
heard of IFC.. sure you can send a revit model nicely
to 3ds if you really want to render with the same
rendering engine.. but you can't do anything with
a model from 3ds except look at it..

scratch another program off list of need to learns! i was imagining the power of 3ds easily forming a mass .. tthought they touted this as a feature for 2012, ...?

if you are an ARTIST- a DESIGNER- then ANY wireframe
modelling program YOU LIKE is the best one..
SketchUP- 3Ds Max- Bonzai3D- Maya- AutoCAD-
Revit massing etc. etc..
i'm not an artist/designer- i use revit for virtual
construction and documentation.. i PAY the artist
for their designs- and then i build them into something
real that i can sell.. i don't care if designs come from a
program that generates .dwg- .skp or from revit
massing- it's all the same to me..
maybe autodesk thought it would be convenient
for me if my designs came from revit massing-
so they built up what used to be a very very
simple massing program that was built into revit..
it used to be useful for things like form roofs
and some kinds of in-place families- i guess..
until a few weeks ago before autodesk
released this new stand-alone massing
part of revit- not many artists would buy
the whole 5000 dollar revit program
just for designing.. and artists who are also
builders are not common..
but i think autodesk made a smart move
turning revit massing into a full-blown
design program- because just look at
all the revit art work that's come into
the revit city gallery..

Single and double Helix's have been produced in Revit for sometime. Here is a quote from Everything Autodesk Revit & BIM 2009 on a competition HOK did:
“The most exciting moment of my design was when time was up, and I transferred all the Parameter information to a nested set of the simple elements. In the click of a button I asked Revit to recalculate over 4500 values, model 1600 solids, regenerate around 20 views, most shaded and shadow-enabled and including perspectives. It took around 3 tense minutes for a quite cryptic image on screen to become the bridge I had in mind.”
....now do that as easily in max

that's a powerful revelation Hub-
if twisted-shape architecture takes off like
autodesk is betting it will- no program can
construct AND design it as well as revit..
so then what i used to think of revit massing
as just being for creating twisted roof extrusions
on rare occasions was really a key to the future
of commercial architecture? probably better
leave bridges to AutoCAD though..

vector 23 ->

they're called architects :-)

McDave- the only thing is- there's nothing on the ARE to do with aesthetics..

your are correct. The elevation requirement was removed serveral years ago.
