Different Rim Joist Materials? Exterior vs. Interior Railing

[JOE-OBRNC]

I am having this problem with a plan of mine and do not have the slightest idea where to change these settings.

 

In the plan that I attached, despite drawing the back deck railings with the same tool, I have an assortment of different rim joists, some made of siding and some that are not.

 

I see the solutions posted here, but cannot find a way to distinguish or determine interior from exterior railing. 

 

 

Am I just not seeing the setting for the interior/exterior railings? Did I create/use a flawed railing wall type?

Try changing the wall type and see what happens.

 

 

 

These are all Deck Railing/Fence-6 Wall Type and almost nothing noticeable changes no matter what wall type I change it too

Try erasing the two railings that you don't want/like and then dragging the endpoint diamond of the one you like to form the other sides.

Okay that worked thank you but do we know why that happens?

 

Everyone seems to imply that railings can be redrawn to distinguish from interior and exterior and I do not seem to have any kind of option for that.

It seems you have painted a few things.

 

 

 

Those Rim Joist automatically populated that way.

 

Even drawing decks independent of the house, the rim joist came in as my default siding for the project: Evening Blue Hardie
