Hello all,

I have this simple garage project to work on, modifying an older plan of ours and raising the car-port section from 9'1" to 13'0" tall.

I've got it put into 3D as all 9'1" totally fine.

I've run into some trouble getting the two roofs to line up properly, at both the wall and soffit/gutter.  Plus the 2 roof peaks, as the 2nd roof on the car port wants to orient the roof ridge peak forward and back rathe than left to right.

I've exhausted myself of ideas of how to make it tie in properly.

Anyone have any ideas ?

Set the top beam height to 13'0". Be sure to uncheck cleanup on the beams.

Ok, I have not tried unchecking the clean up on the beams.  I will let you know how it turned out, thank you Rick.

The front beam of the carport will need to move back. How far? Depends on the roof pitch and the actual difference between the 9'-1" (exactly 9'-1"?) and the 13' (exactly 13'?).
You can use the calculator to figure out how far to move the beam back. Enter the roof pitch as Pitch. Enter the difference between the wall height and the top of the beam as Rise. The resulting Run will be how far to move the beam back from the front wall.

As Bill mentioned, both front and rear beams will need to move together and set to 13’ top of beam to get the look of the 2d and have the ridge line up. Of course side beam set to 13’ also.

 

your covered area will probably decrease by about a third of the existing building depth(depending on roof pitch)

 

do you have a right 2d elevation? It will show the difference.
