2x's Auto-generated on top of deck joists

[rlackore]

When I auto-generate deck framing, CA draws 2x members on top of and parallel with the joists; these 2x members are placed on the Framing, Deck Framing layer. They are always the same depth as the planking specified in the Structure tab of the Room dbx.

They display in x-section:



...and in orthographic:



I don't understand what these 2x members are supposed to represent. Is it a bug?

Interesting, doubt it is a bug, post a simple plan and somebody will look at it.

I bet you have your planking defined incorrectly. You probably have a defined a large gap between planks, missized the size of planks and have rotated them 90 degrees from the way they should be.

Create a new blank plan with a square deck. Compare the Floor Structure and Deck properties for the deck room in your existing and the new plan.

I began from a new blank plan in the first place... but I started another - nothing on it - drew a square deck, same result. These are the settings, straight from the default template:





Maybe there's something obvious I'm missing?

Go to the deck's Room Spec. >> Structure tab. Click on Planks, Joists. Select layer 1 and click on Plan Material. Click Edit. Change Type from Framing to Area. That should fix it.

Too easy. I'm still having trouble wrapping my head around all the little things in CA that have large ramifications. It would normally not occur to me that defining a Material should affect how CA builds things - to me, coming from a 3D background, a material is texture, bump map, specular map, etc. Some of my struggles have just been with terminology.

Thanks for the help.

Hmmm, this is SO un-intuituve

does this make sense to anyone ?

I'm sure I will never remember this little tid-bit of a trick

Aaron's explanation made no sense to me, that being said, I think the OP messed something up and Aaron was fixing it. Hmmm I made the same mistake eons ago and it took a while for me to figure it out......

I just reverse engineered it to get to the OP's issue, and now I understand what was happening. I am not sure why it is doing what it is doing, but I now see it............... now I wonder how I could use this little feature........ got to think about it.............. nope, I never did this before, but it is semi interesting........... sleepers maybe?

To me it appears that the framing from the deck is trying to frame up to the floor level of the main home.

Also, I do sympathize with the OP, since he is right - in other modeling apps you deal with shapes to create "logic" defined by your knowledge - the app isn't going to do that for you say in Sketchup. The flip-side problem I see in CA, is that just when you give yourself over to the "logic" CA brings (knowing basics of how a structure is put together), you end up going back to shapes and your own intuitive nature to complete a "work-around". Its the back and forth that causes some concern - so you have to complete a model using both how CA thinks a building is put together and how you KNOW a building is put together. Its a dance I am learning....
