Tech Graph Talk.

LawdyLad

So, who's doing tech graph next Monday? I'm looking forward to it and it's my personal best subject. However, my Pre was very difficult and I have a feeling this year will be tough as the exam is gradually becoming harder. Thoughts?

Honestly I don't know if I'm good or bad at tech graph.. In first year I got a c3... In second year I got an A.. In the pres I got a D hahaha it'll be grand, I'd say I'll do the elipse/parabola, rotation, transformation and development questions...

abcdefghijkl

I scraped an A in the pres. Still a little stressed about it though. I always end up pretty short for time in tech graph exams. If the same order of long questions comes up, I'll be doing question 1 (orthographic projection), 2 (rotation), 5 (transformation) and 6 (ellipse and parabola). I'd say the short questions will be grand, so not too worried about those.

My favourite subject . Tech Graph is my best and favourite subject, always has been. Got 95% in the mocks.

I am ! ANY PREDICTIONS ?

onlinenerd

I am predicting a parabola or ellipse at an angle.

Dont mind that

Be grand weekend just do some drawings beee granddd

Lookin forward to it agree it is getting harder but really its not that tough of a subject. What Q's do you plan on doing? I'll probably do Q1,2,5,6 but maybe 4 instead of 1.

I'll do q1, q4,q5, q6 but I can see q6 coning up very hard so q2 is also an option!

CathalRyano

I always hate the constructions and difficult stuff in rotations. I mean I'm good at rotations it's just those constructions and all that stuff they put in that's impossible to figure out that irritates me. I usually do that question but with all the hard stuff they put in it I might do developments or orthographic instead.

For Q1, I can imagine it being the same as usual as long as surface s isnt some awkward shape. I am predicting Q4 to have a solids in contact question rather than developments as it is long over due. Q5 never changes. Q6 will be very difficult in my opinion and I can see it including many constructions along with an inclined ellipse.

Yeah its difficult to predict with tech graph seeing as part of the subject is problem solving!!!

Monaghan hardy lawd

My favorite and strongest subject, I got 98% in the pres and all I can say is that between Friday and Sunday try to consider what Q's you will do and practice 2 of each.

How do i prepare for short q's? I've only had a tech graph teacher in 1st year and in 2nd-3rd year the other teachers left us in class or just drank tea and ignored us. I got a D in TG. That's my lowest result ive ever gotten.

If you understand all the things on this you should be able to do a few questions. A free hand sketch Question comes up every year so practice that (it is usually a round or cone or cylindrical shaped object such as a cup). Perspective is guaranteed to come up on the short Questions so here is sample ones https://www.studyclix.ie/Subjects/Junior-Certificate/Ordinary/Technical-Graphics/Perspective, remember alll lines go toward the two points on the left and right or else vertically. If you have a good knowledge of geometry (xyzplain) their could be Q relating to that.
Hope I helped:)

I ma doing q1,q3,q5 and q6 and q2 as a back up if an insanely hard question comes up

Do exam papers, the same types of ones come up every year. If you don't know how to do one, look in your book or look it up online. Or ask on here, I'm sure someone might know.

isometric projection ftw!

We were taught the axonometric projection method rather than the isometric scale.

Two questions:

How do you do Transformation Geometry without the figure looking wrong at the end? It's very hit or miss with me.

How do you deal with diagonal lines in perspective drawings?

Ensure that you know enlargement and reduction. It can make the rotation questions harder, especially if you don't know what to do.

It's all about being extremely precise. I know that's difficult in an exam situation, but if you lack neatness in the transformation section, your figure will look a bit deformed by the end. Make sure you do each step accurately, from using sliding set squares for parallel lines to using a compass to find points.

ajguy97

our TG teacher said were allowed to use tracing paper so our class uses tracing paper for the transformation geo and it really helps :L and it makes everything a lot easier

ajguy97

and ofcourse we had to put the tracing paper along with the test paper :L

A97

How does that work exactly?

LawdyLad

When dealing with vertical lines in perspective, I would recommend just bringing a vertical line up from each point on the given incomplete figure and then bring your lines to the vanishing points. Once you have these lines, it should be fine to draw the final image as you are usually given a 3D pictorial view anyway

All that ellipse bullcrap messes me up. I haven't got a clue how to find the major or minor in all these different circumstances, it seems so random... Same with tangents. Anyone have any tips to help?

Just work backwards to what you usually do when drawing an ellipse if you use the concentric circles method.

Drift_King_33

Development or Solids in Contact this year? Solids in Contact came up last year

abcdefghijkl

Any chance that either Orthographic Projection (Q.1), Rotation (Q.2), Transformation (Q.5) or Ellipse and Parabola (Q.6) won't come up tomorrow? I'll be screwed if that's the case, as I have no backup.

Also, regarding materials for the exam, tell me if I'm missing anything here; t-square, set squares, compass, rubber, pencils, topper, masking tape, protractor. We don't have to bring our own paper, do we?

It usually does follow that pattern so you should be grand for tomorrow.
I'm bringing the same and no you don't have to bring your own paper.

A97

1, 3, 5 & 6 have never not come up. (In recent times anyway.) One year, the Rotation question was Enlargement and Reduction. That's an easy question though so you should definitely know it. It might even be part of the Rotation question. Question 5 is either Developments, Solids in Contact or both.(Shudders) I reckon that we'll get a development. That's only a hunch though.

A2 paper is provided. Work on one side of the paper only.

A2? Are you sure, I've seen my examiner has a packet of A3 paper next to the metal box with the exam papers and equipment.

onlinenerd

A2 I am pretty sure

examstress

Any predictions for question 1 & 2 ?

A97

We were told that it's A2. I've only used those in the Mocks though. Every drawing I've done has been on A3 paper.:o

Predictions? They're basically the same every year, just different shapes and figures. Just be aware how to do auxiliaries/rotations, elliptical shapes and how to draw all of the polygons up to ten except for heptagons and the different ways to draw them. (Octagon in a square for example)

We never covered question four For question two what are the chances that a rotation question wont come up because we were never told how to do the other q. 2's I realllyyy want an A !

A97

Once in ten years. The last time was 2003.

examstress

auxiliary ?

A97

Auxiliary elevations and plans. They come up in short questions and in Q1.
X1 Y1 lines, transfer heights etc.

Technical Graphics holds the honour of the only past exam papers I managed to finish. (The HL Long Questions that I'm doing anyway.)

CathalRyano

Guys, the questions don't change. It's the same 6 every year. The same questions will be numbered the same on each exam paper. If you've studied the ones that have come up in the last 10 years, you will be fine.

Colouring pencils maybe for section 1?:)

Good luck everyone ! O lord Jesus I better do well ! ;D
