Why are my rafters changing sizes?

[frank1]

Using Home Designer Pro 2023, I'm rendering a pavillion on a slab. Within the roof defaults, I changed fascia and soffit/eve to "opening (no material)" and the roof surface and ridge cap to brown corrugated metal. I set it on posts with footers and manually drew roof planes. Rafters initially didn't render. When I opened them, despite having changed them in the defaults to Fir framing 1, under materials they displayed as "opening (no material). I fixed that with the eyedropper. Then I realized my rafters didn't render the proper depth (9 1/4") nor did my ridge beam.

 

In "End2" jpg, the rafters don't display the depth of the rafters on the right. Oddly enough, if I peel the roof surface back and move any rafter in the slightest, it instantly changes to the proper depth.

 

Within "End2a" vector view, there seems to be an underlayment that's causing the problem. It also stops the rafters from sitting on the roof beams in the birdsmouth cut as shown in "End2b" jpg.

Any help would be appreciated.

I've uploaded my plan from my previous post. Sorry, I should have already done that.

from my look you do not have walls for the roof to rest on so program freaks out as it wants the roofs to sit on wall.

 

Make walls and set them to be railings

 

For Side walls - Open them in the edit dialogue:

ON rail Page:

set the railing to OPEN

Set posts to POST to BEAM 

Define start and end post as you wish either half, full or auto - I suggest FULL for your plan as out in the open

Their is a tab for manually defining beam dims later

 

ON NEWEL/BALUSTERS page

Set dims for posts Width (think wall width)

Max spacing 10ft or whatever you want (set it so just bit more then what you have now)

for type either Square or choose one in from your library

 

For front and end walls do the same except change post spacing to bit more then width of pavilion.

 

So after walls then it will make a room - Choose Patio or similar.

Define room in more detail.

Set foundation monolithic slab 4" thick

 

then have it BUILD FOUNDATION.

Now you have foundation and walls.

 

GO to default settings for framing and set first floor ceiling framing to what you are using for JOISTS and spacing. Set roof pitch define rafters dims and spacing.

 

Auto create roof.

Adjust if needed but for this simple roof should be fine.

 

Build Framing and modify framing to suit.

 

 

You issue is you do not have a room
