Changing Floor Joists Type

Recommended Posts

Hello,

I have a situation where in need to change the floor joists type from I Joists to Lumber 2X10" to match the existing house. Some of the steps I have taken are.

1. I went to the default settings -> Framing  then clicked Edit and under both Subfloor  Floor -1 and Floor -2 I changed the Joist type to lumber but the cross section doesn't show lumber still shows I joists.

2. I can click on each individual Joists and change it to lumber and then is displays correctly. I do receive the warning telling me that my "automatic floor ceiling rebuild is turned on would you like to turn it off."

The ideal way is to set the defaults first, then draw.

 

Setting the defaults afterwards requires that you force a rebuild of 1st floor, floor framing by rebuilding the foundation.

 

You should check, and leave checked, Automatically Rebuild Foundation.

 

If you have a 2nd floor already built and wish to change, change the structure here and check rebuild.

Thank you for reply Eric,

I did go back and check the automatic foundation rebuild but, that didn't seem to change the floor Joists to reflect the Joist type that I changed  default settings -> Framing.

Post your plan file and I'll have a look. Close Pro before doing so.

Check your defaults, then delete and rebuild the foundation.

Are you looking at the 2nd layer of your floor framing?

I have similar problem, 1st floor SLAB CONCRETE, that is the default.

 

But 2nd floor is PINE BEAMS, that cannot be the default, checking the default turns this to concrete, going in circles. Plan attached.HD FORUM.plan

so are you wanting exposed pine beam ceilings?  I'm a little confused how you are calling your floor levels your concrete slab should be layer "zero" then the floor with the walls is layer "one" and so on.

Unclear what you are asking.

The slab is UNDER floor 1

 

It is clear that what ever I do the floor 2 structure is concrete when it needs to be 2x8 or similar - I specified PINE BEAM, no, no need to expose the beams either

no, its a house, it doesn't matter, second floor is second floor and it should be 2x construction

Maybe this helps, from the help file.

The floor framing for a given floor is always created on the floor below. As such, the floor framing settings for a given floor are found on the Floor panel for the floor below it. For example, the floor framing settings for Floor 2 are found on the 1st panel, while the floor framing settings for Floor 1 are found on theFoundation panel. See Floor and Ceiling Platforms.

In order to create the floor framing for Floor 1, a Floor 0 must be present. If a Floor 0 has not been built, the Build Floor Framing checkbox on the Foundationpanel will not be available.

well that is very confusing, convoluted and just not clear at all.

 

at 0 its a foundation, sounds spot on - did you look at the model?

 

at 1 it says floor supplied by the foundation room below

and

monolithic slab

 

so as far as I am concerned - that is correct 2.

No and yes, it does not work.  I stated real clear, the first floor is concrete, I do not want the second floor to be concrete - if the assumption is it's a full floor, it comes out as that & can't change it.

 

It still doesn't work if you follow the instruction of this room over a garage (I started there to begin with before posting the question).
