Complex multifloor roof help
SoftPlan Version:
13

Would anyone be willing to help with this roof?  I can almost get it but there is something not quite right that I'm doing.  I recently went through all the lessons in my manual and have looked at videos here but still, I'm missing something.  Here is the front elevation for the house I'm currently drawing.  What I can't quite get is the main roof coming down on the same plane to the bottom floor about center (second gable from the right) of the elevation.

I can take a look at it for you but since I no longer have version 13 installed I couldn't make any changes that you would be able to use. All I could do would be to try to tell you what you would need to do to make it work.

You can attach your drawings directly to the Forum just like you did the image. Just use the 2nd field labeled "Upload Files". You can either zip both floors into a single zip file or upload each one separately. You get a new upload field available after each file upload.

Bill thanks so much.  I'll

Bill thanks so much.  I'll add the drawings.  I really look forward to being able to upgrade soon.  I have had to quit looking at the demo disk for now. wink

The files you attached had no roof. Kinda hard to tell you how to correct the problem with the 2nd gable from the right when there is no roof on the plan.

Sorry Bill, I didn't realize

Sorry Bill, I didn't realize I had removed it.  Attached.

Gable

There are 2 problems with the gable.

  1. The right edge is set to be an Intersection. It needs to be changed to Hip.
  2. The Left edge is attached to the upper wall rather than the matching wall on the first floor. You can temporarily adjust the upper wall back out of the way then attach the roof to the first floor wall. Then you can adjust the upper wall back into place.

Thank you again Bill.  I had

Thank you again Bill.  I had not noticed the right edge being an intersect and the trick of adjusting the upper wall back did the trick.  I'm wonder if the upper floor front wall is playing into not getting the exact plane as the drawing I posted above.  I am attaching a jpeg of a rough elevation with the roof corrections and the new upper floor file.

Roof

From what I can tell by looking at the desired elevation there are a couple things that are different. First, your pitches are lower. Your plan uses 10:12 pitches whereas the desired elevation uses 12:12. Secondly your main ridge is too high. This indicates either a longer span or a wall height difference. Since your front wall appears to be at the correct height I suspect the problem lies with the rear wall. Check the original plan and see if that rear wall which is in the 2 story area should be shorter. I suspect that it should not be as tall as you have it drawn and it is pushing that main span too high. If the original plan contains a roof plan you should also verify that you are using all the same pitches as in the original. It looks to me as if that pitch coming off the rear 2 story wall should be lower and as previously mentioned the wall itself should be lower as well.

I do see what you are saying

I do see what you are saying about the ridge placement.  Looking at the bird's eye it appears to be in the correct position to me.  

 

The original plan was drawn with a 10 ft lower floor, the builder told me to do it at 9 ft on my plan so there are two 9 ft floors with flooring system between.  As I have been doing this roof I'm finding things on the original that just are not correct.  The original is a 12 pitch I believe (no roof plan was available).  The builder asked me to put it on a 10 pitch.  On the lower floor there is a combination of different pitches, primarily 6 and 10 though the back porch will be a shed at 4. The original plan also was drawn without showing brick or siding on any of the exterior walls so I had to get as close to the exterior dimensions as possible and the adjust where necessary. If I didn't say my head is swimming right now I would be fibbing.  Really a good challenge.  

 

I'm not sure what to do on the front but I think it is such that I can manipulate the drawing now to make it right.  One other question, how do you get both roofs to show together?

 

Thanks for all your help on this Bill.

One other question, how do you get both roofs to show together?

What do you mean? Are you asking how I made the image showing both the original and your drawn elevation? If that is what you are talking about I did that in Photoshop. You could do basically the same thing in SoftPlan by importing the images and scaling them to be the same size.

No I was speaking of looking

No I was speaking of looking at them both in bird's eye view but I figured it out.  Thanks.

Bill I looked at the home in

Bill I looked at the home in wireframe view 3d and also looked at the elevations on the plan I received from the builder and honestly don't think the view of the photo I posted above can be achieved.  On the plan I am working from the side elevations show a ridge front to back and the front and back elevations side to side which would indicate a flat roof in that area.  When I looked at the wireframe view I determined that the front wall of the foyer would probably extend through the roof so I know that part of the ceiling will have to match the roof plane.  

Thoughts?

Change 1 pitch

Bill, try changing this one roof pitch and see if that gets you what you are trying to do.

Elevations are incorrect

The elevations provided by the original designer are incorrect. Notice the highest ridge shown on the East and West elevations. For that to happen and for them to match the front and back the highest part of the roof would have to be flat. I'm pretty sure the builder doesn't want a flat roof up at the top of the roof.

The front elevation is incorrect as well. For that front plane to go all the way down to the gables in front of it the roof plane would have to be an extremely steep pitch or the gables would have to extend out about 12' in front of the roof wall.

So essentially you are trying to match a roof that can't be built as drawn. My only suggestion would be to try to match the look as closely as possible. Either that or do like the original designer and erase the fascias from the front roof plane and pretend they don't exist. But I wouldn't really recommend that if you ever want to do work for that builder again.

I agree on the flat roof the

I agree on the flat roof the way they have it drawn.  The client wouldn't tell the builder who drew the plan.  None of the openings matched from the floop plan to the elevations either.  

Bill the gable I have been trying to plane to should probably be part of the lower roof don't you think?

 

I'm just going to let the builder know tomorrow that the roof can't be done that way.  Did you see my note on the gable on the from porch below?

Gable note

If you are referring to the note that asks why the porch gable roof does not work correctly it appears that you have gables on both the front and back of the porch roof. Change the back side of the porch roof to an intersection set to Auto Pitch and it should work correctly.

Bill I changed the pitch on

Bill I changed the pitch on the back and have made some notes on the jpeg.
