Deck Framing
SoftPlan Version:
2012

I am adding a wrap around porch to a house I am developing in Softplan 2012.  I used a four-step (draw/deck/deck components) approach in doing so.  First, I placed PT 2x10 rim joists around the entire perimeter.  Second, I placed double PT 2x10 beams periodically as needed.  Third, I placed joists at 16" o.c. from beam-to-beam.  And, finally, I installed the deck surfaces above.  This method resulted in the framing I was hoping to achieve, as well as allowed me to turn the decking material at the corner, as desired.

I have three questions as a result:

1. Is there an easier way (not that this was difficult) to achieve what I have described when creating a multi-directional deck?,

2. I would like to use PT 2x8 joists, but rim joist and deck joists keep toggling to each other's size.  Am I missing something?, and

3. In the "3D textured" view of the model, I am seeing the butt ends of both rim joists at the outside corner.  Can this be avoided?

Hi Phil

Your rim joist and deck joists adjust to the same because you have the same number for your level. To be able to have 2 different heights, for example, your rim joists should be level 1 and deck joists level 2 (don't confuse when changing it with the number of rim joists. You just have to adjust your offset for the top to be equal.

You could draw by selecting it your rim joists and deck joists at the same time saving you a step.

If you're seing the ends of your deck joists, your deck joists are probably extending to the outside of your rim joists instead of the interior.

Hello Yvon,

I did not even consider "level" relative to deck joist positioning and size.  That worked great!  Thanks!

I am not sure I can do the rim and deck joists at the same time, in that the deck joists are hanging from beams, and change direction at the corner.  I have a beam extending from the outside corner of the house to the outside corner of the porch which accepts the joists.  The deck boards also terminate over this angled beam.

Also, to clarify, it is not the ends of the deck joists I am seeing, it is the ends of the rim joist at the outside corner of the porch (front and side).  I would prefer to see it on the side only, or miter it if possible.

Rim joists

Have you checked if your rim joists are overlapping in the corners which would cause the ends to be visible in both elevations?

I have.  I have even toggled "display everything" to make sure I do not have an older attempt showing up.  It appears correct, in plan.
