Model and Measure: De-Mystifying Hip Roof Framing by Measuring in SketchUp

What You See is What You Measure:

Using the model explained and created in Part One and Part Two of this three-part series we can measure every angle and length required for actual rafter layout. This video shows easy steps to use for accurate measuring:

With a bit of imagination I think you'll realize that there is a whole lot more information available in the hip roof model than the few features covered in the video. Every length and angle contained in the model is easily measured for layout purposes, well beyond the basic hypotenuse dimensions generated with rafter tables and calculators.

Visual Advantage:

I hope you see the visual advantage of this model and measure method over more traditional rafter table and calculator methods. While there's no calculation shown here that can't be figured any number of other ways I find it a handy feature when access to a computer is available. Also, the more complex the roof problem the more helpful it is to use the Model and Measure system. If viewer interest dictates I'd be willing to demonstrate the modeling aspect of this method to show off-angle or mis-matched pitch hip/valley roof framing and how the method can be used to layout, cut and assemble these non-typical roof systems.

Working Model:

If you choose to download the working model used in this 3-part Model and Measure series from the SketchUp Component Warehouse just click HERE.

I hope you've found some useful information about hip roof framing and modeling in this series. Take a second to let me and other viewers know if you found it helpful (or not) with comments or a thumbs up/ down.

On the other side of the room is a pool table with a big screen TV on the wall. Inside decor is LSU :-) There is only one door with a small window on each side. Metal gable roof and siding. Walls are insulated. Simple but charming.

I'm giving your "series" idea some thought.
Would you give me some details about the type of structure you have in mind? You mentioned the man cave on a slab, but what about roof type (gable, hip, other?) approximate size, type of exterior finish (siding, EIFS, brick, other?) types of doors and windows etc?.
My thought is that the tutorial series could go through various stages in an attempt to show the whole process and it might as well be fairly close to the building you are thinking about.
Thanks again for your interest... we'll see what materializes.

The shed series was very good. I guess what I'm after is a little more detail on the carpentery aspect of the project. Such as what size and length 2x?'s is needed and how many. How many sheets of 4x8 OSB do I need with minimal waste. How much concrete is need for the slab - and how to frame it, etc.

You have addressed many of those questions before. It would be nice to see all of the answers in one series. Maybe I'm asking for too much :-) Thank You and I'm sure anything you decide to do will be just fine.

I'll see what I can do.

Assuming you've watched the early posts at The Digital Jobsite (from 2010) that cover "building" a small shed in broad strokes, do you have some specific points that are troublesome?

A complete structure gets into architectural/engineering territory with potential code, structural and safety issues where I hesitate to tread but it might be feasible to cover it in some fashion. Hit me up with some feedback to see if we can put legs on this idea.

Thanks for watching,

I would love to see a series that teaches how to build a slab structure from the ground up. For example, my Brother had a outdoor "Man Cave" built that has a game room, kitchen, and bathroom. It is an open floor plan. I would like to draw it in Sketchup (detailed). Although I can find my way around in Sketchup, I'm no carpenter. You are excellent at both as well as teaching. Thank You.

It's good to hear you like the posts. And thanks for taking a moment to comment.

BTW, I'm always looking for new topic ideas to cover so feel free to offer suggestions for things you would find helpful and useful. Chances are, if it's something you have an interest in other viewers will as well.
