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..

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