STAIR TYPES

[athanasiosmavrides]

does anyone have any idea how to make a 270 degrees stair continuously? is it capable or ADT is better when the stair time comes

Thanks

[dpasa]

ADT is never better than REVIT.
By continuously you mean using only the "Run" option?
You can make whatever stair you like with boundary defining and placing risers.

Thanks DPASA

YES but HOW? I am about to buy ADT 2005 or Revit and I believe Revit is quite faster and better than ADT. My previous experience was ADT 3.3 and as I have seen Adt2005 is quite the same. My only difficulty was with stairs. I can make only straight stairs, whilst I mostly design 270 deg stairs (due to code of practice in my country). Any Idea how can I create such stair types (270 deg cont.). I am using Revit 6 evaluation. Do you think it has anything to do with this version?
Thanks in advance!!!!!!!!!!!!!!!

What do you mean by 270 deg stairs? Can you post an image or something?

[aaronrumple]

You mean like this?

[beegee]

I always thought that was 180°, but then - I live in a metric world !

[stuntmonkee]

I would assume he's talking spiral? Maybe? :?

[beegee]

Maybe referring to 3 flights created at once. I've never been able to get Revit to do that properly. The stringers and railing usually get screwed.

[stuntmonkee]

wow, yeah, that is a mess to try. . . .but I doubt ADT can do that either.

[Architeria]

I've never heard this term (270 degrees) either but I believe it refers to a stair with four runs (&3 intermediate landings) so that the last direction of travel is 270 degrees from the initial direction of travel.

Basically a square stair.

certainly some ADT vocabulary ;-)

So of course Revit
does this kind of stair

[athanasiosmavrides]

You mean like this?
I am sending you a 270 deg type stair (continuously)

[beegee]

A stair like that could be quickly made using the boundary and tread tools in sketch mode.

Not continuously - using the run tool, ... if thats what you mean.

I saw mention of spiral (helical) stair in this thread. Where did spiral stair go? It was in an earlier version.
Thanks for any lead.

[beegee]

When you select the run tool for stairs you get a choice of sketching by line or arc from centre and end points.

Thanks for reply BeeGee but I'm looking for one with centre post.

Got to http://revit.autodesk.com/library/html/index.html , then to 'revit samples', then revit 6 samples then the stair samples file. There is a spiral stair with centre post drawn there. (It is drawn with a separate post in the centre though.)

I tried to do a spiral recently where the stair actually passes through about 450 degrees from floor to floor. Not easy but I worked it out by 'bolting' 2 stairs together (as you can not sketch the run through an angle exceeding 360 degrees.)

[athanasiosmavrides]

MY STAIR PROBLEM IS THAT THE STAIR IS LOCATED AT A CORNER, THEREFORE IT CANNOT BE DONE SPIRAL. THE EDGES OF THE OUTSIDE EDGES OF THE STAIR, ARE ATTACHED TO THE WALLS, AND THE INNER EDGES ARE FREE, USING A POST OF ANY TYPE.THE PROBLEM IS THAT IT HAS TO BE DESIGNED WITH CONTINUOUS RISERS SUCH AS FIG 1 , AND NOT SUCH AS IN FIGURE 2. DON'T ASK ME WHY I NEED TO MAKE SUCH STAIR. FIRST OF ALL DUE TO CODE OF PRACTICE IN GREECE AND SECOND DUE TO THE SPACE REQUIRED FOR SUCH STAIRS. USING ADT YOU CAN PRODUCE SUCH STAIRS, BUT IS IT POSSIBLE USING REVIT? IF IT CANNOT BE DONE I AM SURE A FUTURE VERSION WOULD DO.

[tobytaylor]

Many thanks Max. Just the ticket.

You can easily make this stair, just not easily with one stair. The way to make this is to create a landing at the halfway point our of a floor, then creat the lower "L" shape as one stair sketch, then create the upper "L" as a second. Then you can edit the railing sketch and have it follow the middle landing(floor).

So the stair settings will either need to have a new level added for the mid landing, or just set the upper constraint to whatever half the overall ht. is.

You can if you need to see it in 3d add a stringer profile to the slab edge.

THANK YOU EVERYBODY FOR YOUR REPLIES. I THINK I WILL BE BUSY THIS WEEKEND!

[gravelin]

Something like that ?

[gravelin]

To do this, I begin a new stair, change all parameters to have my own type (especially uncheck the use of the calculator)

then I draw the boundaries and the rises using corresponding buttons (run button is unusable in this case)

If you have and ACAD DWG of the stair (as it seems in your pictures) it will be helpful to load them to pick the lines with the pick lines arrow button in the option bar.
