Cross Section Question

Just installed 2014 and so far I like it, however, I've come across something that is a little baffling.  I am working on a a 1 1/2 story with an angular stairway and three things are presenting a problem and hopefully someone can set me straight. Item 1: I have a section line running throught he center of the stairway and if I select "Break" in the stairway options my cross section goes completely dark.  Item 2: I would think that if break was chosen the hidden lines would appear at the upper end of the stairway on the1st floor plan view and on the lower portion of the 2nd floor plan view, however the dashed lines are in the same location on both the 1st and 2nd plan views.  Finally, I was trying to insert a recessed wall under the lower half of the stairway, but when I try to fine tune its location, the stairway move as well and I cannot make the top of the wall rake to the same angle as thebottom of the tringer.  If I select "rake top of wall to stairs" both top and the bottom of the wall will rake, but not be accurate to the angle of the stair incline.  I'm guessing the wall is snapped to the stairway and that is preventingme from adjusting the wall without the stairway moving too, but I'm not sure.

 

Thanks, Tom

Cross Sections and Stairs

When you select "Break" for a stairway it is automatically excluded from the model. SoftPlan assumes that you want to show the stairway on the other floor as the one to use for the model. To get the stairway to show in the model edit the stairs and select the Common Tab. Place a check next to Extract In Model.

For the stairs on the lower floor you would want the stair to originate from the floor and go up. The stairs on the upper floor should start at the floor and go down. You make this happen by editing the stairs and setting the Reference End. So for the lower stair the reference end should be Bottom, since the bottom should be at the floor. For the upper stairs the Reference End should be changed to Top, since you want the top of the stairs to be at the floor. This will also reverse the dashed lines and the direction arrow if you have it enabled.

To move a wall without moving the stairs also temporarily disable "Attach". Attach is located in the Status Bar along with Group and Link Floors when you select the Move command.

To make a wall follow the same slope as the stairs place the wall under the stairs. Edit the wall and select "Fit to Stair". This will adjust the wall so it follows the slope of the stair but at this point is is fitting to the bottom of the stairs. Edit the wall and next to Wall Height click the button that says Multi-Height. Edit the dimensions and increase the heights uniformly to make the wall taller while maintaining the same slope. Alternatively you can edit the stairs and on the Common tab uncheck Cleanup. Enter an offset Up distance to raise the stairs up, say 4' or so. Then fit the wall to the bottom of the stairs. Finally set the stairs offset back at 0" or wherever it was before and check Cleanup again.

Stair Reference

Thanks Bill.  You've cleared up most of my questions.  I am a little beset by the stair origination command though.  I have the stairway, on the main floor, set to to bottom and the arrows go correctly.  However, if I change the origination to top on the second leg of the stairs, it also changes the first leg to top.  I see the stairway on my 2nd floor plan via the overlay command, but cannot edit it there.  Do I need to insert a separate stairway from the 2nd floor to the 1st setting it's origination as the top?

 

Thanks, Tom

Stairs

Yes, you would actually have 2 sets of stairs. The stairs on the bottom floor with the Reference End set to Bottom so that the bottom of the stairs is on the floor. And an identical set of stairs on the upper floor with the Reference End set to Top so the top of the stairs is at the floor.

See the tutorial Stairways in 3D for an explanation of what the Reference End setting does.
