Problems creating gable style roof

[keyboardman]

I'm having great difficulty creating this gable style roof for my model. I'm using roof by picking point. The roof portion on the very top extending to the rear of the house. Also the very back end of the house looks as if I will be having more problems. I'm not going to created the shed at the rear of the house and just include it as the rear wall maybe. I'm new at this so any help will be greatly appreciated. Using TFP14PRO.

Hi, Welcome to the forum.

I think you have done really well so far! It is not a simple roof when you have multiple gables close together.

The rest of the roof is actually quite easy. Select the roof, drag the rear edge so that it covers the walls then right click and select Cut Opening. Then all you could is cut out that corner of the roof.  The walls will automatically extend so it is all done.  

The image may make it clearer.

Was that the only problem with the roof or did you have another one with it?

Thank you for your help, but the problem is with the very top gable, it should extend more toward the front as pictured. My next problem is the rear end that strange roof and the laundry room appears to be lower, I believe it on a concrete foundation w/o crawl space and the same with the garage. Can you apply different foundations to the same project?

Hi again,

As I commented before -it is not a simple roof.

I had not noticed the gable on the roof front top previously.  There are several ways to do this.

Probably what should have been done was to create this edge of the roof first as a Dutch Hip which would have achieved what you wanted and then add the major gable - not sure if it would have stayed there when you added the other gable though.
You could probably add it using the Dormer Tool or the Surfaces Tool, or you could add another Location with the same settings as the Ground floor and add a bit of roof to make the gable project out of the other roof.  The solution I have used below is similar to this but I have done it on the same Location.

Draw a full width of roof "by picking points" out in front of the house. Right click, select Move and move it into place, so the front edge sticks out to whjere you want it and the pitch aligns. Drag the two edges in, so that they are just inside the outer edge of the wall and set these two roof edges so that the Overhang is almost zero (eg 1/8"). This is necessary as the overhang will protrude through the side walls otherwise.  This solution means you have a some roof inside the other one - so I am assuming that there is no attic space used, otherwise this roof would be in the way and a different solution would be needed.

The room and roof at the back should be on a separate Location if it has different height walls.  Create a new Location (Settings/Building Locations) by selecting Ground Floor and then Add Location.  This will create a new location with the same settings as the Ground Floor location. If the wall or ceiling height is lower, change it in the new Location and give it a name (eg Rear Section).  Now you can draw the walls for this section, they will take on the Location wall height and you can add a roof in the usual way.  The Garage should probably done the same way - on its own location.

When you are editing the plan now you must select the appropriate Location from the drop down selector. The other locations will ge greyed out.

If the walls of the rear section are the same height as the rest of the house, (as they are in your second model), then you can add the two section layered roof (as in the photo) "by Picking Points" as you did before. Draw the higher section first, set the two long edges to gable. Next draw the lower section, so that it DOES NOT OVERLAP the first (or it will join in). Again select the two long edges and change them to gable, then select the two short edges (so they are green and the long edges red). Right click, Properties/ Support and Details tab and change the Support Height to 7'6" for example.  That whole section of roof will lower by 6". Now select only the long edge that is adjacent to the other part of the roof and drag that edge under the first roof.  This will give you one roof under the other as in the photo. (see thrid and fourth images)

Ask again if you need more details.

Hi, keyboardman and Allan!
Allan, it look like the it come to roofs with to complex forms the easy way is to convert to surfaces, like our friend Joe.
Surfaces is a very powerful tool, this weekend have I draw one little cottage in timber there I have convert the roof to surfaces, I have also use the same tool to make angle beam. If you right click then you have marked the surface you will find a special menu for the surface commands. I will publish it on the forum then it is finish.

I think this is the tool to use in this case, it is only little more planning to do it, you have draw the roof in same order that the original is build, because of all extension of the house.

Hi Robert,

Yes the Surfaces tool is very clever and flexible but I think it is probably it bit hard for very new ones to understand. The other problem is that if you convert a roof to surfaces you cannot change it back again, so the roof remains in pieces and it can make enditing a lot harder if you have to change things later on. Alright if everything is fixed and wont change later I suppose.

This particular roof is not too bad really, but obviously is a bit difficult for a new user. Good one to learn on though!!

Hi again! Yes! I agree with you  Allan , it is the last resort so to say. That abut convert back to floor, ceilings or roof maybe something to the wish list to next upgrade.
