How a Pro Builds a House in Sketchup Part 2

Continuing from Part 1 viewtopic.php?t=723&p=4194
Continued in Part 3 viewtopic.php?f=18&t=723

hello fellow sketchupers... last week we left off with...
"step 11
repeat this process for your foundation, your first level and your second level and third...
next time we'll create components from each of the layers and show how to work on your house while looking at it too..."

since we last spoke, you should have traced each of the floor plans on your house and cut out the doors and windows.now you should have your floor plans on separate layers. "Level 001" and so on.
Lesson_2_Pretalk.jpg


before we begin

let me stress the importance of a "Tidy Drawing"... Layers, Groups & Components... make sure to use them often and make sure to not to rely on the Hide command very much. Hide should be used to hide geometry lines, not things you are not working on. having everything on controllable layers and groups will allow you more control later when the model becomes larger and harder to deal with. the ability to work on specific areas will make your life much easier and make exporting your drawings much easier later on down the road. so when you build something, check it's layer and get into the habit. when you group something, go back and name that group in the group list window. this will allow us to view as much or as little of our plan at any given time, while leaving them connected, although you might find it easier to not only make Level 001 Layer but also a Level 001 Group so that you can move it around with out destroying vector lines. that's your chastisement for the day....

a word about detail. from this point on you need to decide your detail level, from here you could start building the rough framing for your house and putting it on a separate layer... if you go this far and even farther by setting a value for material you can use your model for very accurate take offs. I use it regularly for concrete volumes and roof square counts and tile counts and so on. for this example we are just going to build the wall shell for visual walk through.... now on to the lesson.

Step 1.
turn off all layers Except the Level 001.
Lesson_2_Step_01.jpg


Step 2.
extrude, or push/pull all of the walls up 8' 1-1/8" or 9'1-1/8" or so on for what ever top plate line you intend.
Lesson_2_Step_02.jpg



Step 3.
now extrude each door and window section up the blue axis 6' 8". this will be our door or window opening.
Lesson_2_Step_03.jpg



Step 4.
now extrude a new face up again to the top of the plate line. if you chose 9' 1-1/8" plate line, then it would be 2' 5-1/8" this will leave you a header area, and now is the time to think about transoms.
Lesson_2_Step_04.jpg



Step 5.
now is the fun part. time to find or preferably build some door and window components. search the internet for real door companies like Pella, Anderson or in my case for this project Peachtree http://www.peachtreedoor.com/products/windows_casement_500.asp. now click on the lower right-hand corner where it says size chart. here you will chose a style and size. use the numbers at the top and side to build your components and also to name them, that way later they will be easy to use again. if you're lazy or just want to be like us kool people you can purchase components from places like http://www.FormFonts.com

Lesson_2_Step_05.jpg




Step 6.
insert your windows and doors at the appropriate level. make sure they are all on our current Level 001. make sure that while you are inserting the doors and windows, that you don't delete the side lines from top plate to bottom. this will be needed for the floor plan sections we will export later.

Lesson_2_Step_06.jpg



Step 7.
Repeat Step 3, 4 & 6 on your other levels. be sure to assign them to their respective layers and groups.

Lesson_2_Step_07.jpg



Step 8.
restrain yourself from adding textures and furniture just yet. texturing and furniture layout should be seen as a reward to your for your hard work on the model, and leaving it until later will allow us to make changes to the structure if a problem should arise in our layout, with out redoing texture and furniture. only use it early if you need it for sizing rooms.


Step 9.
we should be starting to see a recognizable structure now.... let's go around and offset corners and exterior walls 4" or 6" for stone facades... also we can do our columns and other exterior attachments. again, layer these accordingly.

Lesson_2_Step_09.jpg



Step 10
now for the crème de la crème.
if you are building multiple copies of one structure or just want to watch your design as it is built. save each of your levels as components and then make copies of each level and stack them in order over in a "Viewing Area" in your model. and put it on a layer named "Whole House" now after you do this, you'll be able to work on each level independently and watch the changes over all on the whole house model....

Lesson_2_Step_10.jpg




next time we'll add a foundation and a roof....

I'll add some screenies tomorrow...

Kristoff....nice job with the doc....I like the level of detail. It is good, clear instruction. The things you are teaching re process are helping to get me organized and a lot more disiplined.

Thanks for your efforts they are most appreciated....Cheers!!

Hi from India,

I am building a new home, we have finalized the floor layout, and construction of foundation already started. I am a bit stuck on the exterior/elevation, like how it should look like.. and if i do that how it will look like in real world...

I have used sketchup before to layout cubicles at my office. Before, our 1000 square feet room just occupied 21 seats, and after giving my sketchup layout, it was restructured into a room which occupies 44 seats with lot of living space for each seat. Every one loved Sketchup!

But, I am not confident about using sketchup to do the elevation of my house. Because, i learned sketchup using trial-and-error method, which is time consuming. And i lack the basics of drawings. I always used to get confused about where my line is getting drawn, is it in x axis/yaxis/z axis... and i still dont know how to draw a line is a particular axis... i click here, i click there, then draw and will check where it came up, if its not in right direction, i will delete it and will try again... and it suX(could some help me out of this?).

I was googling around 'how to draw house in sketchup' and then i got this post(few minutes back), and i am happy. I think this is what I was looking for. I used to resize my floor layout given by my architect to mark dimensions of each room and stuffs... but I had no idea how to do that in the 'right way'.

I am 'closely' following ur article, so that i can do things in the 'right way'. Thanks for finding time to write this article, and thus helping poor souls like me...

While waiting for those screen shots which you promised... I am going to start plotting my house from 'Step 1'.

Wish me good luck

thanks
Vijoy~

thedifferenz,

how your structure will look in the real world, to be as real as possible... use real world materials. and I mean componenets really. if you are going to build a wall, don't just draw a face and pull it up, create 2x4's 2x6's 4'x8' plywood and sheet rock, and then manipulate those comonents over and over, using the "make unique" command on the context menu. put these together to create your wall and then you will know exactly what the framer in the field will run up against.

"But, I am not confident about using sketchup to do the elevation of my house. Because, i learned sketchup using trial-and-error method, which is time consuming. And i lack the basics of drawings.

this should be solved with the color of the axis in sketchup.



I've posted those screen shots... and I invite everyone to add their WIP (Work In Progress) pictures to this thread... and feel free to ask questions...

emahfuz,

thanks for the kind words... I have a design you might like called Paixao...

I mainly did this thread for the exact reason of thedifferenz, he found this page via Google already and I just made it a few days ago... that is shooting the rank of this site up... and getting new visitors... the more helpful posts, the more folks we get...

thanks, shawn.

it is a curious name for a design as it means passion in portuguese. it can also be a fairly common surname.

kris,
Your tuts are good:You have heard the thing about give a man a fish, feed him for a day, teach him to fish.... judging from the muscle in your template I think you could write a great tut on template building that would power the lessons in push/pull walls and roofs even faster and farther. Keep up the good work! thanks!

Re: How a Pro Builds a House in Sketchup Part 2

Postby DzineTech » Sat Nov 17, 2007 5:16 pm

Greetings all, my 1st post on these new forums. Well done to Coen setting this place up; a far superior environment and interface than the new google groups in my opinion.

Anyway back on topic. I've read through this how-to and felt that I should add my own thoughts on the advice given in a constructive manner that will hopefully provide some of the newer modellers with an alternate method of construction.

My main disagreement with the workflow provided is the procedure of the wall construction. There was good advice given regarding the tidyness of our drawings however I feel that one of the most important area of modelling/CAD housekeeping is to not create faces and edges that aren't required. If you follow the procedure of push-pulling rectangles to form the external walls in a series of panels as shown, you end up with 4 lines and 1 face between each panel junction that simply aren't required (note: only on panels which run parallel!). This method of modelling is akin to building blocks whereas my personal preference is to somewhat different.

Stage 1
My advice would be to trace the outline of the external wall to form a shape and offset the wall thickness inwards. This will leave you with 2 shapes (1 for the thickness of the external wall and another for the internal void) Of course the internal line of the external wall may have areas where it differs from the plane of the external but the line tool and eraser can quickly tidy this up as required.

Stage 2
With the correct shapes now drawn, a simple push pull of the external wall face to the necessary height will extrude our entire wall in one operation instead of several and we will have the minimum amount of faces required. The top and bottom faces of the wall extrusion can also be deleted as they won't normally be seen unless in section. Internal walls follow the same procedure of tracing the outline to form one face and extrude as before.

Stage 3
Window and door openings. My preference is to make components of these and I would locate the insertion point at the top center of the component. Once made I would create a guideline at 2.1m (sorry, child of the metric age here!) above internal finished floor level and place my door or window on this. A simple horizontal move will finish the required location of the component.

Previously I would create components that would cut the external wall face however now I tend not to. As SketchUp is a suface and not a solids modeller my components wouldn't cut the internal face of the wall. to solve this I now draw a rectangle on the external wall face, tracing the opening of the already placed window/door. Push-pulling this new face inwards the depth of the wall thickness (either type the distance or switch to wireframe and snap to an internal face edge). This makes the soffit and jamb faces (internally and externally) in a quick clean operation and should not require any data cleanup.

I hope it all makes sense and as I recognise a few names from the former sketchup forums I know you guy's (and gal's!) will probably be aware of the workflow already but perhaps some newcomers will benefit from it.

Time for a coffee...

Postby Krisidious » Sat Nov 17, 2007 5:16 pm

there is a method to my madness...

the reason I want those extra faces... it prepare for autocad and drafting a house's construction documents. if this were just a 3D model I would agree... but it's for a pro to make a real house out of.... so we need to be able to cut sections at any poin where a window is and see the mullions...

thanks for you advice though.

Sorry, but I don't understand what you mean by requiring the extra faces for autocad; perhaps you can explain or illustrate with a screenshot?

but it's for a pro to make a real house out of.... so we need to be able to cut sections at any poin where a window is and see the mullions...


I assume when you mean pro you mean that you will produce construction drawings based on the model and these will be issued to a professional kit manufacturer (timber frame/metal frame) or to a contractor for his brick layers. Your requirement to see the window components (head, cill, transom, mullions, jambs etc..) works exactly the same for section cuts in my workflow as yours does; the important factor being that the window component would need to be detailed enough to reveal enough information wherever the section planes are located.

Postby Krisidious » Sat Nov 17, 2007 5:18 pm

DzineTech,

yes you are correct in your assumption, however if you were to cut a section above the window, most people have removed those faces, and thus the window only shows up if you cut the section directly through the area in which the window is located.

so we may both be right...

DzineTech points out that it is the proper way to model, to remove any faces which are not seen or used. which I agree with.

and as he or she points out, you can model the house and make construction docs from it using his method, if the all the windows and openings are at the same level, through out the home. however if some windows or openings are above others with in the same floor or plane, then you will not see them when you do a section cut at the nominal level.

am I being clear? I'm trying, I'll make some screenshots later like DzineTech suggested. and I'll try to get part three done.

Kris, I understand the difficulties that varying window openings poses if you are trying to show a section through both at the one time. I'm hoping your screenshots will explain how your wall construction method achieves this.

Personally I wouldn't even consider taking a SketchUp model to create construction drawings. For me I keep use it for 3D only and use Microstation for all technical work. The workflow I use gives me speed and keeps file sizes to a minimum. If your method works for you then good. I'm certainly not egotistic and insisting that what I do is the only way to do it and all other methods are wrong.

PS I'm Male :D

Krisidious,

I was wondering how your plans for Part 3 were coming along? I'm sure I'm not alone in saying that I very much enjoyed part 1 & 2, and I'm eagerly awaiting part 3 to this excellent series!

Keep up the good work!

Great thread!

I just got into SketchUp a few weeks ago, and did a mock-up of my home renovation plans. It came out pretty good, but I sure wish I had seen this tutorial first. I learned a lot of what you're advising the hard way-- through making lots of stupid mistakes.

I'm fortunate in that I'm starting with a .dwg file, so I don't need to trace anything. I look forward to rebuilding my house using your instructions.

Thanks Gaieus, got it.

I have a question though, forgive me if it has been explained already. Why make the floorplan a texture? I import my plans as a picture file, then line it up on the x,y,z axis.

Krisidious, I think building this way will solve a problem I have been having, trying to pushpull window cutouts in a wall that is not 90 degrees to the axis. Just have not been able to do it. YOur way looks like it should work. :D

This is a great tut. Got anything on using the sandbox tools? :ugeek:

Very good tutorial - I'm very new to SU, so please excuse this question, but i got lost in step 4 - how can i extrude another face on top of the door volume? tried drawing a new face on top of the door, but i always pull the original volume.

thx a lot
