Can someone please help me understand this roof plan?

vel_pp

I'm just trying to understand this roof plan. I couldn't understand from where to where the measurements are made. Could someone possibly help? Thanks.

MMM looks like a suburban hell house to me.  Has the bump.  Has the mish mash of hip and gable.  Show us the rest!!!!

I love how both cm and m are used for dims.

Is this a new post thread like the floor plan thread, but instead of guessing the building, we name the flaws?

The measurements are taken between the lines in the direction of the arrows. You're welcome!

This is why I hate it when drafters manually override dimensions ... total of blue dims should not equal total of red dims.

If that was Samuel's homework, and he couldn't figure it out ... he'll never finish architecture school anyway. Plus, I have a hunch as to where this image is from, and it wouldn't be homework. If I can verify it tonight when I get home I'll post an update.

I'm intrigued.

I'm probably wrong, the metric measurements are making me second guess my second guessing of the first guess.

There aren't any bricks to count so I'm not sure why Balkins is getting brought into this.

The assignment prob. was "identify what's wrong here" or something...

My hunch was wrong. I still feel like I've seen this before, I just can't place where. Seeing the OP's comment below assures me I didn't do their homework though, or if I did he wouldn't understand it. It's pretty apparent he's got much simpler things to figure out than what I've illustrated above.

I've been told that if I instant fired everyone I wanted to for bad drafting, we wouldn't have any drafters left.  I responded with a general comment about my boss wanting less change orders, and if we didn't do any work, we probably wouldn't get change orders.  Got a mild laugh from the higher up in question.

overwriting dimensions is not bad drafting, it's incompetence.

can someone please teach me how to read this plan? Can someone mention what these measurements correspond to? Any basic idea would be great. Ex: The rafter measurements, etc.

Your plan is flawed. Dimensions are to either the edge of the blue zone or the white outline. This is very inconsistent and makes it impossible to read without making huge assumptions. Figure out what either of these regions are first, then work from there.

Sep 29, 17 10:41 am  ·

vel_pp

Yes man, couldn't figure out what those regions are. That's why came to this forum. This stupid plan drains my energy.

Sammy, ask your prof or classmates for clarification. The drawing is shit without further context.

Sep 29, 17 1:52 pm  ·

yes i know man. could at least explain what the lines are representing. for example: the triangle at bottom represents rafters and the ridge. i can't understand anything other than that.

Glad you found it helpful even if the OP didn't. I googled "how to read roof plan" and it was one of the first few results.

Could you please explain me the dimensions? I want to know what those 15.5 meters are? Also those 210 cm in left, 126 cm. please help

Sep 29, 17 1:42 pm  ·

i'm asking what about the measurements? ti figured out that the 5.8 meters is the rafter span. likewise what all the other given measurements denote?

Sep 29, 17 1:59 pm  ·

I like the idea that vel_pp is actually a pretty experienced roofer who otherwise has never worked off a set of plans, and an architect sent him this and said "build me a roof"

Sep 29, 17 5:07 pm  ·

vel_pp

what are those 126 cm to both the sides of the rafters?

Sep 29, 17 2:10 pm  ·

really thanks a lot man. what are those 4.4 meter and 5.3 meter on the sides of the rafter span?

those are lengths of roof.... if the blue actually is the roof's footprint, which clearly we do not know.

Sep 29, 17 2:21 pm  ·

vel_pp

if the blue is roof's foot print then the 15.5 meter in the top and the 3.2 meters in the vertical side represent what?

Sep 29, 17 2:28 pm  ·

what do you call those 2.1 meters?

Sep 29, 17 2:41 pm  ·

also those 210 centimeters?

What do you call those 15.5 meter in the top, 210 centimeter in the side, 3.2 meters and especially those 2.1 meters. i just need to know the terms. someone kindly help.

I blame the professor on this one, for providing such a bad example of a roof plan. Looks like Balkins did it.

man, could you please tell the terms for the 15.5 meter in the top, 210 centimeter in the side, 3.2 meters and especially those 2.1 meters. i just need to know the terms.

but balkins would have dimensioned it to 1/64" accuracy using drones.

what i'm asking is 15.5 meter is the length of _____________

please tell at least the closest terms. something would be better than nothing

You've all been looking at it inverted. That's a swimming pool man. white outline is the coping. Seems clear - blue = water. No idea which part is the deep end though without some sections.

What's the issue? Simply convert the metric units to imperial?
