How did DCG go for ya???

Rossie17

Was it just me or was that goegraphical goemetry far too easy... I hope I didnt make a mistake...

user12

I only got part A of it but I thought that was dead easy!!

user12

I was abit annoyed that the triangle question was changed dramaticalll!

Rossie17

Oh yeah, I got two separate lines for that. I think it was a simply inclined plane?

Cormac2791

****. ****. ****. Bastid. Bollox...

Yep, I'm sure I did ****e! Got two questions almost fully out, part a of geographic geometry, 2.5 short questions, and just started b2

KealanOCarroll

The tersecting planes were ABC and ABD so the line of intersection was AB....jus look perpendicular to it in plan, then along it and it gave dihedral angle (was around 160 r 170 degrees)

The hyperbolic parabaloid was píss easy...the woman with the hat one....dead simple!

The interpenetration took about 15mins....didn't even need an auxiliary!

Geologica Geometry was easy....given the strike, dip took 2 or 3 mins to get, then jus measure 25mm away and draw another parallel line which gives the footwall....thickness of the stratum was just the shortest dist between headwall and footwall...

Parabola in section A was dead simple, Oblique plane in section A was straightforward....

...finished over an hour early....reckon I got a solid A anyway:D

UpTheSlashers

Pretty Tricky. I wonder how much Aviva paid the SEC for that question
What did ye get for the thicnkess in geologic geometry? Roughly 40 or 50 mm?

Niall09

Couldn't have gone better tbh. I think the only thing i didn't do great was getting the vertical and horizontal traces in the planes question. Depending on how good my project is, i could possibly get an A1!

UpTheSlashers

I officially hate anyone who thought it was easy. No offence.

Rossie17

To get the dip what did you guys do... I just extended the strike and the points as a single line. Found the dip. Then I marked 25 back from f and found the perpendicular distance. That was too easy I hope I didnt miss something?

Conor108

Thought the Dynamic mechanisms was grand but jesus the assembly! I just couldn't picture what went where....Ended up drawing components randomly :D I'll lose marks for positioning I know...

Anyone remember what angle they got for the cut plane yoke in Sec A?

I'd be very, very happy to pass

There wasn't an interpenetration, or I hope there wasn't anyway cos I was banking on it! Other than that I was very happy with the paper, Roads was easy and planes was grand aswell, did all of Section B but 2 of those q's weren't learnt by me so I'll lose some marks there. Overall it was a lot better than expected!

Rossie17

You had to find the angle? **** I must have missed that bit I just drew the object cut in plan + elevation..

45 degrees, They'll give anything between 40 and 50 degrees

the only difference was that u were given the line of intersection this year as opposed to having to find it last year. my dihedral angle was about 165-170 degrees:P awesome test overall:P:D

how big was the semicircle supposed to be.. i guessed 10mm... other than that it was really easy.. the rising road part was all embankments so it was just 10mm apart the whole way across and that was it..

Not in B anyway. Also this year was a lot easier than last year. Hopefully they mark the projects harder to make up for it.

ya i did 10 too it was right :P

mmmmmmmKayyyy

Yeah grandest.. For the hyperbollic parabaloid (hat) question, did anyone else get the horizontal trace parallel to BC? If not, how did you do it? ha:pac:

Eire-Dearg

Can't believe how easy it was.

Section C was piss easy. We've been doing those hard surface geometry Qs out of the Folens books and this was ten times easier, plus our teacher just went over it this morning in due time.

Road and mining was a little weird, why did the division of lines one of the lines on the triangle?

The perspective was tricky but I think I got it completely right, aux VPs and all!

The one thing I didn't get was the last part of the planes one.

ya it was meant to be parralel to bc you have it so that it contains ad then bring it over to contain bc extend it ti touch the gound line and bring it straight up and bring B on elevation across to touch it ( thats your point on vertical trace) then just join wher ad touches the gound line to that point and there u have it

Was easy apart from the assembly was fairy horrible..

did u mean that u get where BC touches the ground line ya?

You know when you walk into a Korean restaurant and you're not entirely sure of the language. You basically pick something at random and hope for the best, you're optimistic about your choice. Next thing the waiter comes out with a brain hemorrhage on a bed of toenails. Ladies and gentlemen.... That is how the Design exam went

dazco

Can someone just tell me in Q B-2 Part D what's the true angle between traces?
I wrote at the bottom of the page that it would be 90 degrees, cause they're on the vertical and horizontal planes.....
I got the angle of inclination to the horizontal plane just in case though as well cause I didn't really understand it......

ya same, our whole class thought it was handy. ya id be hopin b1 maybe a if the examiner is a good person haha

Conor108

I too failed the pre but that wasn't too bad at all. Sure Im only after a C3 overall. Remember the exam is only 60%

id say lots failed pre cos we were workin right up to the pre on the project and didnt do a tap on the practical stuff

MyHair

Short questions, easy-peasy got them done without any hassle.

I did B1,B3,C2 and C3.

B1- Completely screwed up on the perspective drawing, but got the plan and elevation done fine.

B3-All done apart from finding the traces of the plane.

C2-All done apart from finding the traces (again)

C3- Fully done, no hassle.

So, all in all I was happy.

THAT WAS AMAZING!

You didnt have to draw the elevation on b1

KealanOCarroll

Dont have the paper here now but there was an interpenetration!

The building in florida or whereven it was....B2 i think....
It was a cylinder interpenetrating the basic rectangular building, was one of the cut types rather than the two solid bodies intersecting type?

The thickness of the stratum hadto be less than 25mm because the headwall was 25mm from the footwall perpendicular to X1 Y1 so the 25mm was the hypotenuse....

I think it was in and around 40degree's.....

mrkrgn2

easiest paper i've ever seen and probably will ever do. did all the shorts, all the b's and c-1 and c-2. i hope they don't change up the marking scheme because too many people got A's

double GG

It actually wasn't that bad. I got 3 out of 4 long questions "done" and then i started two others and did them as far as I could.

I made a few mistakes though, mainly in the Surface gemoetry one, where you had to make a seperate development of Sides B+C, I simply got the true lengths and "attached" them to the sides of the existing elevation, shouldn't lose too much marks though hopefully

Another was in the Intersecting planes where I, by my own laziness, was marking the "up-20" and "down-70" of point C I think it was, I marked up 20 by placing the set square on 20 at the "xy" line and Of Course I only mesaured down 50mm then instead of 70 ... I got the Dihedral angle etc, Just it will be a little bit different. For the True shape I just used the true length of the other side ... I also left a little note on the sheet about this mistake :cool: :P

Didn't go too bad, looking for a C2 so Hopefully I should get it

SolarCreed

I think that exam was worryingly easy, I keep thinking did I miss something or not like that question B-3 where they gave you the intersection, at first glance it was like, *t **** is goin on here* but twas handy out! And those short questions were a joke, along with C-2!
All in all very happy with that exam, on to physics!
Id say marking will be rough......

Couldn't agree more!*high5*haha

mmmmmmmKayyyy

i just realised i screwed up the auxiliary vanishin point in perspective,, so pissed with myself.. how much do ye reckon Id lose for that ha?

Titan9

Was that auxiliary vanishing point above or below the drawing?

wonderfulname

Not too shabby a paper, easy C, hard A, just the way it should be really.

Dynamic was beautiful, couldn't have asked for a nicer question! Blanked on Geologic though, still cant get over something as easy as B-2 being on the paper (I'm assuming thats what everyones calling interpenetration, its not!) although I forgot how to do the D part, lovely short questions too.

00cruzer

i was very happy with that,perspective was sound,got full marks in that,da question with 2 triangles was tricky,i jus got true lenght of the line and then a point view of that to get dihedral angle.the point B was not touchin the line so it 90 degrees until it touched.the road question seemee to easy if you ask me,jus hope i got it right,My thickness was 30mm.the actual road part was simpledynamin mechanisms was sooo easy,got like a heart shape for the locus.short questions wer easy nuf too.Thats a good B in the bag!!

It was below the left vanishing point and drawing but a bit above the ground line (if I recall correctly).

Well according to the marking scheme of the perspective drawing from last year (albeit a part A) "Finding AVP" was 2/20 marks, presuming you drew in the sloped edges with some sort of AVP (right or wrong). If you did a method which got you an AVP which still worked relatively well I reckon you'll only lose about 4/45 marks for that.

Also, there was no interpenetration question this year. Yee're confusing it with whatever B-2 was.
Exam papers for DCG are up already btw. Here's section A (i.e. the one you couldn't bring home)

Diabhal Beag

I think I did OK but I'll probs scrape a C3 (Hopefully including my NES project).

To all those who said it was hard, it could have been sooooooooooo much worse.

WallyGUFC

No interpenetration. It was just like a weird balloon-cock shaped dent in the front.:D
Shorts were piss.
B2, B3, C1 and C2...were easy.
I am delighted!

i put it below the horizon line
