How can i draw curved wall on sloped slab?

Hi Solari_1

This is an interesting problem, but I found a work around you could use. Please refer to the attachment provided. I hope this helps you!!

There's several approaches. Probably quickest and easiest would be to draw the wall on the lowest Ref. Level and define it's Top Constraint as the highest Ref. Level (the same top constraint defined for the other walls) - and then use the Attach Top/Base tool to attach the Base of the wall to the floor.

The wall in question will not attach to the angled floor when joined with the other walls, but will attach to the ref. plane drawn parallel to the angled floor.

But, there is no wall attached to other walls in the OP's screenshot, so I don't understand your point. The OP is asking how to place a wall on the sloped floor. Doing it the way I described will work. There are several other ways to do it well.  

[PijPiwo]

There are no walls, probably because the OP couldn’t do it the way he/she wanted to - it’s my assumption though.

@Anonymous, to continue with my assumption that you want a continuous wall all around, another option would be to model the floor as one piece and use Modify Sub Elements to get desired heights. All walls will attach to this floor with no problems. Just be aware that Modify Sub Elements option will change the thickness of the angled part of the floor - steeper angle, bigger distortion.

Cutting the bottom of the wall with a void swept blend will work too if Mod. Sub Elem. is not an option.

Maybe I miss something here , but it works if you

• first make a rectangular floor slab, edit it with Modify Subelements, then Attach Top/Base with Attach Base works for floors. (first screencast)
• If you want the floor to be exactly on the wall contour then , you can use  Void Floor to Cut the first floor (second screencast)

This is correct and a very simple solution, IMHO.

hi @Anonymous,

Make sure as well that the wall you want to attach overlaps your slab in plan view entirely.... just to make sure!

Other question, did you use the slope arrow tool or su-elements for the creation of your slope?

slope arrow to make the floor slope

[Sahay_R]

Can a reference plane be created along the sloped slab and used to cut the wall?

[FGPerraudin]

re-hi @Anonymous,

I have tried it on my computer as well and I don't get what is going wrong with your model.

OK, so here is a screenshot just to be sure that you do the right things:

First of all, select your wall.

Are you sure you click on the (1) button?

Then that you check bottom attachment (2)

And then pick the floor you want to attach your wall to (3)?

PS: you can attach your wall to several floors as shown on my picture

i made ref plan on sloped  slab  then i made attach it worked

[ToanDN]

@FGPerraudin

Try it when you have a string of more than one walls.

[FGPerraudin]

Hi @ToanDN,

You were right, I have just had some tryouts with a string of walls.

My conclusion is that Revit Cannot attach base of wall if the handle of the wall rests onto a slab edge.

Basically Revit cannot calculate the junction of the wall if its skatch line lies onto one surface and its thickness onto another one (try it it is quite interesting...)

But it works if they do not!

1 works (wall handle on a surface)

2 doesn't (wall handle on the edge)

Very interesting to know for further notice!

Cheers,

François

thank you so much

Actually, the two "instep" side walls will join to the floor using the Attach Top/Base method, just as I described. The walls are joined as well; however, because there is a change in direction at the top and bottom of the ramp, there is a "hinge" in the walls - just as there would be in the as-built condition.  

[ToanDN]

@barthbradley 

Come on, the walls are clearly not joining properly no matter how you paint them to be:

And why accept hinges when you can do without, not by one, but multiple approaches which are relatively simple?

[barthbradley]

Gimme a break, Toan.

My exhibit only demonstrates that the wall CAN BE attached to the floor. Exactly as I said - twice. I also said the there are other ways to do it – twice.

I’m not advocating an certain approach; just saying that it can be done this way. It appears not everyone was not able to.

And, when I said “join”, I qualified it by saying there is a “hinge” – which actually would mimic the as-built framing.

Obviously, if you are designing circuit boards; this 1/32” gap wouldn’t be an acceptable tolerance. But, in building construction; printed on paper at ¼” per foot – it ain’t getting red-lined in plan check! I assure you.

...but, if it makes you feel better Toan; I thought you had this one nailed for best Solution. I'd have chose it, but unfortunately the OP didn't. Better luck next time.
