Penn Foster Structural Plate 2

[ReMark]

While the image looks OK a closer examination of what you have done can be best accomplished by posting an actual DWG file for review and comment.

Hi,

I have attached the file. This if one of 5 projects I have to complete by June and they are killing me. I am not familiar with the terminology at all and have to look everything up. I know I have a lot more to add to this plate before it is complete, however as it is there is a few things I have concerns about.

I am not sure the girders should not be seen, though I have included them as its easier to delete them than add them in. Also for the second elevation, the concrete slab goes slightly below the C-channels and I am unsure this is correct.

While I love working with AutoCAD the terminology and the round about way Penn Foster describes their projects has me moving slowly through the projects and these forums are a lifesaver!

Thanks for the DWG file. I'll be back with comments.

What terminology are you referring to?

A few of us here have some concerns about the Penn-Foster CAD course. I'll leave that discussion for another time.

[chloe2012]

Basic terms that I assume are standard in the engineering industry. I am in the Oil and Gas Industry as a geologist, but I have a minor in GIS and when I was applying for GIS jobs they always asked for AutoCAD, so I decided to do an online course and found Penn Foster, that and I love learning software. I have no engineering knowledge, so terms like keyway and other basic terms I have to google to find out what they supposed to look like. How they have information throughout the booklet is very confusing and misleading as to what information they want on each plate.

A couple of things caught my eye right off the bat.

1. Why do you have a 6 inch space between the bottom of your slab and the 8" layer of sand below it? I would expect the sand to be directly below the slab to act as a support.

2. You have concrete on the second and third floors sitting right on top of the C9x20 beams. If the contractor poured cement it would fall to the slab below because you neglected to include the steel decking that must sit atop the beams.

3. You can assign a linetype of "Hidden" to the layer your C9's are on. This would still leave them visible but you would be indicating the beams are behind something such as steel cladding. Do I need to provide an image? The beams would also have to be shown in better detail (the flange) and the clips that tie the beams to the columns would have to be shown as well.

4. There appears to be some rebar missing in your footings.

Let's stop here for the moment. OK?

Well chloe2012 you are not only learning AutoCAD you are learning a little about structural, civil, and HVAC as you progress through each P-F project. Perhaps they should have included a syllabus in the project PDF file.

[chloe2012]

1. That's how I had it initially, then I saw a few of the drawings here and assumed I had it wrong.

2. I did not know about the decking. I will add that to the drawing.

3. I will change the linetype to hidden as you suggest. Would I also need to put the girders on a hidden linetype? I was going to show that, but I thought I had to show it as a detail on another plate so I thought I could have left it out of this drawing. So I will include that as well.

4. I emailed the school before I founf this forum about the rebar, as I did no understand what they meant by 2" overlap in their description and am awaiting to hear back from them.

I have seen in some drawings on other threads that a bolt is shown on this plate, I was unsure if to show it on this plate as I believe they ask for that as a detail on a later plate.

Yes, I am afraid I bit of probably too much to chew. Now I just want to get through the program with my certificate . Unfortunately I can be a bit of a perfectionist and a nerd so I like things to be done properly as much as I just want to complete the program.

Again, if other people haven't already, thanks for taking time out of your schedule to help us out!

As I recall isn't the garage supposed to be enclosed in vertical siding affixed to the exterior?

The overlap in the rebar is when one piece extends beyond the end of another.

The drawing is meant to be plotted at a scale of 1/8"=1'-0". Putting anything other than a line to represent the centerline of a bolt will be so small when printed it will appear as a blob on your drawing.

So you think I should still show the ties and clips from the beams to the channels in this drawing or leave it for a plate later one that shows details? And just but a line for the bolt?

That's what it says for the entrance in the booklet:

A supply entrance to the lower floor is on the building’s
south side. It’s a sliding glass door centered between
columns 3 and 4. The rough opening for the door is 12′
wide and 8′ high. Above the rough openings is a steel
I-beam header, W10 × 45. The header is placed so that
the flanges are horizontal and the web is vertical. The
height of the header is 10 1/8″.

The clips are sufficiently large enough to be seen even on a 1/8" scale drawing (aren't they 4x6 and 1/2" thick?).

The line for the bolt, as you put it, would only serve to designate the centerline of the bolt. Again, at 1/8" scale drawing an entire bolt, washer and nut is not worth the time and effort because it will print too small to be noticeable. Save that kind of detail, well, for the detail. Makes sense doesn't it? Details are normally drawn at much larger scales to show things that cannot be easily shown at a smaller scale.

Do you have a question about the supply entrance?
