Drawing pitch roofs
-
Dear friends
I have just started drawing pitch roofs in sketch up
as you see the roofs are not drawn properly and they looks fragmented
would you kindly advice me how to draw such roofs please. thank you very much in advance

Hi:
It appears that even your ground plane is not a consistent flat surface from which to erect the building. The vertical edges of your walls seem not consistent in length and therefore you will not be able to form a flat face.
May I recommend that you consider starting over with more attention to consistent dimensions. Believe it or not, the reconstruction process will produce better results. I would not worry about the tree right now. It is just in the way. If you need to consider the tree, mark its ground position with short crossing lines or circles.
If you have not already, I would suggest that you watch some of the youtube training videos, or take advantage of the Help Center found in the application's top line menu Help. -
Looks as though you are fighting to create a "planar surface" but lacking in "co-planar" edges from the building structure itself. You must remember sketchup only works in flat edges and flat faces. It is rigid and will not conform to framework that is askew. Picture trying to screw dry wall or sheetrock to lumber which is out of plumb and level....it will not work without breaking the sheeting or adding extra framing. Sketchup is the same way. All edges must be plumb and level to each other in order for a solid sheet (face) to be formed.
In your case with the pitched roof I would say your best method to resolve your non-planar edges is to "cut" them so they work. You can do this by creating a cutting plane out of a large rectangle which is grouped. Draw the rectangle off to the side and then position it to the house and at the angle you want your roof to be and aligned with the lowest point. Once it's in place you can run the "intersect" command and intersect the grouped rectangle with the house. This is like a big saw that will slice the irregular surface and make it regular. You have to then delete the excess.
Another option is you could use the plugin Extrude Tools from TIG and use Extrude Edges by Vector tool. This will allow you to select the parallel edge and extrude it perpendicular to create your roof surface. The tool will group the new shape and you can then use it as a cutting plane or just push pull it into the roof you are looking for.
Best of Luck.

Dear friends thank you so much for the responses, I highly appreciate it
In designing this kindergarten, I decided to not merely rely on perpendicular angles
as could be seen in roof plan, the rooms are not in a rectangular shapeso the first question is :
-
Do you think construction of such a building would be very difficult and costly?
-
in drawing the roof itself :
I first tried to draw the walls and then tried to joint the corners that's why the roofs look terrible
I am totally agree that sketch up is perfect for drawing rectanglesI have to submit the design by this coming Thursday for clients' comments, then preferably I would like to not change the design at this point of time
now the question is
what is the easiest way to draw roof which is in fact a rotated surface.
should I copy the plan and rotate it?
or
try to draw the section and extrude it?Intersection of walls and roofs is a great idea, it never even occurred to me
should group both wall and roof separately or make component from them?
thank you so much friends

I'd definitely group the roof itself. Best would probably be to make it on the ground plane, group it immediately and move it where it is needed then rotate it. Now select the roof group and your walls > right click > intersect ... selected. Hide the roof temporarily and delete all unneeded parts of the walls (that would stick out of the roof)
-
thank you very much sir Gaieus
thank very much for all responses -
On a short deadline, you could always just take the easy road and use the Eraser Tool + Shift to hide the edges you don't want seen. Although this is cheating in a sense, it may allow you to continue working on the model. The roof is an easy fix if you are experienced at problem solving and understand the basic logic of how sketchup works, however this takes time and practice and it sounds as if you are short on time. Perhaps if you posted the model, someone might lend a helping hand.
-
Thank you very much EarthMover, I uploaded the model,
I tried to press the shift and the erase tool, but they corners do not hide, I am sorry I am a real newbie would you kindly have a look at the model please. thank you very much
-
To say the least, the model is not perfect at this state therefore without starting certain parts from scratch, it is impossible to clean it up perfectly. Here is a quick and dirty version however. I have also reversed a bunch of faces.

may I advise getting Instant Roof.

Sir Gaieus
Thank you so much for your help, I am afraid the file is empty
would you kindly send me the model again. sorry -

sir Krisidious
thank you so much, does it works for all types of roofs? thank you again -
Instant roof does not work with all kinds of roofs but with conventional ones. There is plenty of information at the site. It's great but I doubt it is useful on this design.
It looks like you have some low slope roof planes (simple shed roofs). It is only segmented looking because you have extra lines and planes in it than are not needed. You've drawn wall planes to continue up to the roof surface, which they do not do in real life. You can hide the upper edges of these planes, in this case, for a quick fix. The way to draw such a roof is to keep it all in one plane. Start with the bottom edge (usually horizontal) and a side edge, giving the slope; then draw all remaining edges in the same plane (for a rectangular roof the opposite edges are parallel to your first two of course). in SU people will often draw a roof flat (parallel to ground plane, then pull up one side. This is less likely to work if the roof is not rectangular in plan.
Gaieus and Adam have probably set you straight for now, but in your next model, try using components for grouping objects (wall elements, roof elements, trees etc.) together. Those trees in the center of the model, all ungrouped would drive me crazy. After grouping (in a "group" or "component") you can assign them to a new layer and turn their visibility off while you work on the building. And see about giving building elements like walls and roofs thickness, so you can create simple and clean surfaces.
As to the style of the building, it will be more expensive to build the walls sloping. It usually is more expensive to build something that is different than the way most of the buildings are done in your area. You can still pretty easily do the sloping at the end of a wall like you have, If you want an interesting interior wall shape (sloping or arching inward) you can build that in after the supporting structure is built straight and conventional.

A pitch roof is covered with a black tar coating. A pitched roof tilts at an angle above horizontal.

I do some pretty freaky roofs... and it's never stopped me yet. only saved me time. shed roofs is an easier one that it does.

pbacot thank you very much sir for the perfect comments
thank you all for your collaboration and great commentsI agree with all of you, the model has lots of problems, specially the trees which later I found they are not grouped,
after the presentation I need to remodel the building again
I will keep in mind all comments thank you
let me seein the real world there are many times we need to show over work to clients and they might change their mind
I draw my plan in autocad
then I exported to sketch up
primarily I didn't try to put different parts in various layers because I wanted to com out with a good design firstI used sketch up in this stage as a tool for gaining some ideas
as it was the first time to draw the sloped roof and little by little I found which parts of roofs need overhangso
as pbacot said I draw many lines. because for example when I draw the roof , and then wanted to extrude it for 300 MM or 400 MM as overhang it was impossible because sketch up extrude it in horizontaly not in the line with the slope of my roofs
later I came to the conclusion that I need to draw the roof plan in autocad and base on that I draw each roof separately
now the main question is
Do you also do the same?
every time you export the cad file to sketch up
and if there is a change in the plan, you draw it again in sketch up?thank you very much again friends

No you draw only the 3D!

Here is the model cleaned up and sorted. Took a bit to separate the items. Did several CleanUp's with ThomThom's Cleanup plugin. Selected and deleted the ungrouped trees using a plugin called "select faces by size". Then I quickly grouped each section, deleted the messy roof planes and redrew them using a combination of Extrude Edges by Vector and Extrude Edges by Vector to Object.
The biggest issue with the model is that it is not drawn with a strict adherence to the red and green axis, meaning it is not drawn square to itself. This makes modeling very tough and makes it next to impossible to recreate this in the real world. Try to read up on the axis and inferencing. It makes life easier once you grasp how these work.
Keep trying...you've got no where to go but up.

Nice Job Adam. I looked at doing the same this morning but didn't have the time it would have taken me. I wouldn't have known to use those plugins either.
I think the nature of the building is to be out of square, but there are actually lines that were aligned to the axes.
Try drawing with a style that shows "color by axes" for the edges and that can help give you some reference even if few line are parallel to the axes.

oh MAN!myou are allll awesomeeeeeeeeb
I am in the office now, luch time, tonight will read all the comments and will take notes thank you sooooooo muchhhhhhh
