aligning top plates with different rafter depths

[chrisinnh]

Back again!  Going to be a habit, working on a Passive House retrofit.

 

Half of a 1986 saltbox will be converted to a clerestory with tji rafters, the other half will get a second set of 2x10 rafters overlaying the existing.

 

When I split the roof planes between clerestory and saltbox, and change the clerestory rafters to 18in tji rafters, Chief drops the top plates.  How do I keep the plates at a constant height?  The roof overlay on the second half of the roof will match the height.

I assume these must be edited or manual roof plans?

 

did you try and move the roof plane in the Z direction using transform replicate?

[chrisinnh]

Yes... edited.  I haven't tried the Z plane as that would involve moving the roof structure and adjusting all of the walls, correct? I was hoping to lock the plate somehow.

assuming the room structure has the top plate set correctly, I think will merely move the roof structure up. i do this quite a bit for teusses

Does the trick, nearly!  I plugged in different values until the bottom of the rafters aligned with the top plates.  But, I assume, the accurate value is the difference in plumb cuts between the two rafter dimensions? 

 

Framing and elevation camera views attached.  The elevation and framing views don't agree.  Two issues: elevation view isn't repopulating to reflect framing; elevation view shows proper rafter tails while framing view does not.

Looks like you may not be showing the corresponding layer. Try switching to the all layers layerset to see 8f the elevation shows correctly
