Has anybody tried the Weldment sample exam? I worked on the 3d sketch, but can't get the same answer as the #2 answer
at the bottom of the page.
I'm getting the same thing you are. Either we're both doing the same thing wrong or the test is wrong.
I'm betting it's a problem with the test. SW doesn't even include the necessary weldment profile to complete the problems.
i confirm, 13912.593mm
kinda makes it hard to get 3-5 correct if you start off wrong.
speaking of questions 3-5 ..
#3; when using the "End-Butt1" option my model appears backwards from the jpeg in test exam.
#5; that's one ugly corner, unless I modeled wrong

You can use End-Butt2 to fix it.

I`d be interested to look at somebodys completed part 5 as no matter what combinations of corner treatments I try it wont look anything like the section BB.
Out of interest, how close to the answers should your results be?
This is the best I can come up with but from the back not very tidy!
here is 2009 version.
use configurations to switch between questions.
There was a thread on doing this type of mitered corner... Look at Josh Brady's second post (i think).
Just throwing my 2 pence worth in:
It took me longer than 25minutes! From the order given in the sample it looks as though that rear corner mitre should be cut using the trim command.
Instead it has to be re-model using groups (as shown by Josh Brady). I suppose I thought the steps would be progressive.
Also that mitre is really horrible from the back.
Mine checks out ok: 13924.58mm
Actually, I'm having a problem picking just the mitered vertical leg body for the mass measurement. When I do the mass properties on only that body, the density goes to 1.000 and I get the wrong weight. I had to delete the other bodies to get the 4602.09 grams. Bug perhaps?
Glad to know I'm not the only one... funny thing is - I tried measuring the mass of some of the other members in the part, and a few of them switched their material density to 0...

that sample exam is ok......but have u tried the actual exam...........
some questions are really difficult in short time..
I haven't tasted it yet but based on my experience with other certification exams, I'm sure time must be sufficient to finish the exam.
The key thing is practice a lot before exam.
yes u r right ..i mean to say there was lot of models in one paper to deal.......
i just gave that exam and i passed it.
Experience is good... got 190.
I found three difficult question ... means.....little short of time.....
Now preparing for mould and Simulation......exam only.
Can anybody know how to make corner treatment given in sample paper.....Find the attachment
I finally took the weldment exam yesterday. I am not a weldment super user. I have really only done about 5 weldment models for work, the sample exam and one tutorial. The tutorial and the sample exam are the only ones I've done using the new functinality of 2009. That being said, I did well on the exam... but I usd all of the time allowed. I spent most of my time on one of the full up modeling questions. My recollection on that question was that I had to use a 3D sketch that I created in the prior question (Multiple choice and got it right) and populate all of the elements with structural elements. It had miter corners everywhere and lots of trimming. That was the only question I got wrong. Seemed like a really good test of the functionality though. Next stop CSWE
p.s. It is kinda funny when you learn functionality while taking an exam. I had never used the little keep/delete toggles while trimming. Like I said I am a weldment noob.
Sorry for waking up this post again, I see the last activity was in 2010. Funny thing is, this is still the sample exam for weldment exam, and I have the same issues some in here run into.
My concern is about question #2, length of the segments in the 3D sketch. As you, and many others in here, I get the lenght to be aprox. 13919 mm. Should be about 5 mm more. If I however create this sketch with normal 2D sketches, and 3D sketches for the legs, I get the correct result 13924 mm, and this is what totally scares me I have tried now to model the 3D sketch with many different approaches without ever hitting 13924 mm.
I just wonder, does anybody still have the part file with this correct 3D sketch, I would be very interested in looking at it, and how you have created it. Thanks.
Edit: No worries, found attachment from Tom Smith, thanks.
For whatever it's worth;
I experimented with following;
- 2D top and bottom sketch connected with 3D 'legs'
- multiple 3D sketches joined
- strict single 3D sketch (as suggested in the practice test)
In all cases I used an offset plane with a 'point-on-plane' relation for the leg at origin (0,0,0) to fix the height of the wireframe at 700mm (understood that the actual length of the leg was going to be greater than 700mm). Was entirely baffled at the different results in measurement from wireframe-to-wireframe, until 'discovered';
- 'Units' in my first attempt were not set to MM to start. Entered '700mm' in the distance box for the ref plane offset (working in Inches I do this all the time), After toggling the units to MM, noticed in the eighth decimal place a 5 instead of a zero. Tiny, but enough to skew results
-Curve endpoints not really coincident to endpoints. Not entirely off in space, just on the curve near enough to appear coincident to the other endpoint'.
-Third file somehow had first curve traveling in the positive 'Z'. Not a big deal until later when answering COG questions. And somehow still off on the wireframe measurement.
Moral of story?
-Set up environment correctly from the beginning, don't challenge the software and do it on the fly. Sometimes 'stuff' happens.
-Work fast but don't be hasty. I like slapping a reference plane in place to secure certain features with minimal construction lines. But if I'm missing constraints or misapplying them, I'm going to waste time troubleshooting later.
-Be grateful to all on this blog for their time and expertise. I eventually got it right using the offset plane but thoroughly enjoyed querying the model provided and studying the build method used as well as all the other observations made.
Many, many thanks for initiating the thread and for sharing.
I am now preparing for weldments cert. Just in case anybody finds this problem too, the author of this thread made the wrong dimension on the side line. It is easy to check them in the drawings. The task gives you the projected 100 degrees, and the author made them "direct". This is the drawing screenshot of the author's sketch:
This is First angle drawing (European, not American). Those .16 of degree is the problem
There are multiple ways on how to get this angle correctly, so i will leave to everyone who is also studying
