Hi Jo Ann! I've copied the entire house outline into a blank plan and it seems to be showing same issue. I guess it might be just the roof shape? Though it's strange it works okay without this little porch protrusion. I've also overlaid on top an aerial shot of the house roof. I'd really like to get the roof to match, I tried doing some manual editing of roof planes but was having weird issues with them not wanting to join up, shooting off into the air and getting warnings whenever I tried to use join roof tool. I think it might be user error though! I can send you the real plan, but it's a bit of a mess at the moment, so that's why I was avoiding it. But I'm a bit worried if you work some miracle in the test plan how I'll get it back into the real plan!! Troublesome Roof.plan

Yes that's perfect Jo_Ann - was that using the room divide wall? I've also been able to get it to work in the cut-down plan I attached by placing a room divide wall where you indicated - I didn't think to try it again in the sample plan (until Eric sounded surprised it wasn't working), because it's not playing nice in the main file - I'm getting the random attic walls for some reason when I try to do that, so I'd given up on that approach thinking perhaps the wall running into the window was the cause of the issues and a show-stopper....

Thanks for the input, yeah I just wasn't sure what the best choice for 0 / 90 degrees was - whether to make it relative to a property boundary or orientation of the house itself, north, etc... if just drawing a floor plan for a house it's a simpler choice, but when trying to include a few structures on a several acre property it's not so clear cut as the two sheds aren't on the same grid as the house. But I've realised of course they are very simple floorplans so it's more tolerable to have them off-angle But in my confusion I chose grid north for 90 degrees as that's what the subdivision plans I have is drawn to and I think I used north pointer then to reflect magnetic north (relative to grid north). I thought at the time that was sensible and it worked well for the site plan, but I ended up with a situation where 0 / 90 deg matched absolutely nothing on the property which is an ongoing pain for working on the house floor plan. So I think I will flip it around using method Eric suggested. That worked well on a plan snippet I tested it on.

There's a hip? in the roof where it should be a single flat plane and the valleys go the wrong direction The split room works if the inner porch room stays within the bounds of the two walls either side - ie if I put it here: But the roof overhang was wrong - it's about a foot less than it should be at that point - and I couldn't find any room/wall specific option for adjusting that. Whenever I tried to move the split room wall out further, then I'd get weird things ike this happening (attic walls appearing): But interestingly I just tried it in my plan snippet and it works fine - so no sure what's going on there - looks like it should work though so will keep trying with that approach. Also I will have to look into why I have cornices extending out of my roof! That's something that seems to have appeared since I've rebuilt the roof with newer version so I'll have to try and go through the settings there. I'm surprised the Gable/Roof Line tool doesn't work as from a couple of demo videos I saw, that's the one I thought would solve my problems, without needing any artificial walls, so I thought maybe I'm just using that wrong.

Thanks a lot Eric, that looks like it'll sort my mess out! Cheers

We have a fairly complex (single story) roof - HDP has always done a pretty reasonable job of estimating the roof planes, but I'm being a bit fussy now and trying to get it to match the roof of our house. This is the first time I've really got into the manual roof stuff, so it's a learning curve and I've watched several tutorial videos and podcast sessions which make it look quite easy but I've spent hours struggling with it and it just doesn't want to play nice for me in 2 areas of the plan. So I'll probably follow this first question up with a second one, but I'll keep trying with that for now,,, For the first part, I have a porch which I want to be only partially covered by a roof. Here is a picture of it in reality. It's hard to see from the photo, but the porch projects about 1750 from the door, but the roof only about 1600 (to the fascia) + gutter. It was fine while the porch was just filling in the gap between the two side walls, but when I projected it outwards to match reality, the roof changed shape and I just can't get it to work - I've tried messing around with a number of things. I'm hoping to avoid fully manual roof planes for this part, although I think i'm going to end up needing to use them elsewhere so if that's the only way, that's ok - this just seems like I'm probably missing something obvious. The two approaches I thought would work: * Not putting a roof over the porch, and using the Gable/Roof Line tool to draw straight across the porch. * Using a room dividing wall to split the porch into an outer and inner part and not roofing over the outer "room". Attached is a little snippet of plan that I hope has enough of the relevant bits to replicate the issue Any advice greatly appreciated Troublesome Porch.plan

Thanks for the quick response Eric Ok that sounds like what I did originally (created off survey plan) and then just rotated site plan (Tools -> Rotate Plan View) so the walls are square - but the grid isn't and (I didn't on early versions but having just upgraded) I get all the off-angle wall warnings. Plus I have to add all the additional know angles for snap to work and then I get too many really as I get the normal 7.5deg snaps as well as my custom ones so can be hard to be sure without measuring what it's snapped to. Or when you say "rotate the site plan" do you NOT mean Tools -> Rotate Plan View ?? Cheers

I think I've made a mistake here - previously when I've done plans I've just drawn them with the house in the most logical orientation and haven't been interested in site plans etc. Walls end up at 0 deg, 90 deg, 45 deg etc... For our current property though I needed to do full site plans for council and it's a 7 acre property and I wanted to model elements of the terrain, boundary roads, sheds, dam, gardens etc etc so I started with the plan so North was 0 degrees. I think that might be a mistake though as the house has lots of angles and they are now really odd - eg most of my walls are at 32.900006° or -57.099994° etc. I've kind of made it work by finding the "Allowed Angles" setting under "Plan" and adding some of these common angles there, but I've always wondered if I did the right thing or if I should have laid out in the most logical way for the house and drawn the property around that, letting north point something other than vertically...? Is there a right/wrong or is it just a matter of preference?
