Basement Stairwell

Recommended Posts

I am having issues with my basement stairwell.  I have studied an earlier post from Aprill11, 2016 (posted by ArtisanDeck and answered by Drawzilla) and I think some of my issue lies with terrain settings, but I'm having other issues as well.  I created my stairwell on the foundation level, then created a room above it comprised of invisible walls with no ceiling or roof.  I defined the room as "OPEN BELOW".  Here are my problems: 1) The walls on the first floor are not entirely invisible. 2) The room is not open to the stairs below (maybe due to my terrain specification).  See attached thumbnails.


While I'm at it.  I have been looking for a Bilco (brand name - don't know what else to call it) door for the stairwell.  Does CA have one and I'm just not finding it?

Thanks for the Bilco doors. :)  Here's a sample plan derived from the plan I'm working with.

If you draw a polyline rectange and outline the opening, you can convert the rectangle to a terrain feature. Once converted, open up the properties and change it to a "hole in terrain". 

As for the walls being invisible, are you referring to them not being seen in the floor plan? If so, that's just your visibility settings.

That solved part of the problem, but why does it add a partial wall on top of the foundation wall (shown here as a concrete wall - I'm guessing about 8" in height, but I don't know because I don't have an actual wall to click on to get a dialog box)?  See attached...



As per your instruction...



It seems to add a short wall on top of the foundation...



I have no wall to modify or delete...

Go to your foundation level, and open up your room specification dialogue box for the stairwell.

Once there, select structure and then change your ceiling height to "-4". I'm suspecting yours is probably "4".

This may solve a few issues for you. Just place door in wall of foundation and good to go. Minor height adjustment that's all.



I didn't see any extra wall on plan you attached. Could be wall got adjusted from room dbx. Just drag them down if you want. Also you don't really need room on main level so you could eliminate the invisible walls. 

Normally I would draw stairs for something like that as a p solid because we require a wall below upper portion. Just use a closed polyline to show concrete fill for sections.

Thanks guys... The problem was with the stairwell itself (with its room specification).  You both have been a big help!


Jerry, I have read a lot of your posts as you are in the same climate as I.  I hope you don't mind if I enlist your help periodically.


Thanks to you both.

      I'm designing a 3 level home.. the main level stairs I want to use are  L shaped from 1st to second.  .I have attached PDF cross section of how I want the stairs to function.. and PDF of first floor showing no stairwell to basement..  I want to place a straight railing on first floor across stairwell as well as stair railing descending ( which is in place).
      I also need to be able to come in from the mud room from the garage on the fist floor.. so thinking I need steeper stairs to basement but not sure how to change the heights etc.
      Any suggestions are welcome.  I have watched the videos and I know you have to start from the bottom and work your way up but not sure how to get the look I want.

      I've been learning CA for about a month and have some challenges on a plan that I cannot figure out.  I have attached a perspective with color markups and the plan.  I would appreciate some input on how to fix these items.
      1. Red: The 2nd floor system is 14" trusses.  I cannot figure out how to fill the two indicated areas.
      2. Blue: I cannot figure out how to get rid of the stair rail against the wall without losing some of the wall behind.
      3. Green: I cannot figure out how to put a cap on this half wall; also there is no ceiling drywall directly above it.
      Any help is greatly appreciated.

      I'm not sure when this happened or how it happened but my ceiling isn't meeting the wall in the basement.  The separation is from the garage.  I created a brand new plan to make sure my heights all matched up correctly and they do.  Can you tell by looking at my screenshots what might be happening or what I need to do to fix it?  Photo on the left is the wall/ceiling in the basement.  The photo on the right is from the garage.
      Thanks so much!

      Here is an interesting issue, (at least for me)... I drew this stairway and created the stair well but when I go to a camera view, the wall comes in at the floor level. The basement is 11" thick ICF and the main level is 2x6 so in real life there is a lip on top of the ICF wall going back to the thickness of the 2x6 wall. I can't figure out why when I draw it like this the lip actually comes in at the framing level of the main floor. When I look at a cross section it actually looks like a section of the ICF wall is slid into the stairwell at that level.
      The floor trusses are 22". I have attached a picture of the project, I am already well underway with this, I am just trying to make some as built drawings so I can work on interior design stuff.
      I can probably make due with it as it is but I am just wondering if anyone wants to try and figure out what I am ,missing here.

      Hello, I'm a new comer to chief architect and need help building the attached stairwell.
      Please advice how to go about making this. The colored in area is drywall with built in wooden handrails.
