Before I even ask, are you allowed to ask a question about the practice exam?
Yes practice exams questions can be discussed publicly but not the actual exam.
First of all I am required by my clients to use SW 2013 (I'm on sp5).
I know, I know, but we cannot upgrade until the client specifies a later version.
On the practice exam, Question 2, a downloaded file, it asks for the number of Negative Draft surfaces.
I have created a parting line using 1 deg draft and the top plane as my pull direction.
The correct answer per the key is 17.
What I get is 15 and 2 straddle faces.
I have done this over and over with the same result..
If that was a test question I would get it wrong...
Is it SW2013 or my machine generating this error?
I am afraid to take the Mold Tools exam because of this..
I got 17 using S2013 itself.
The key is to create the parting line correctly and don't try to fake it. Check the attached video.
I wouldn't even attempt to "fake it."
I have created let Solidworks create the parting line both automatically and by manually selecting tangency around the edge.
I have rebooted my machine and no matter what I do I get the two straddle faces.
I contacted my re-seller and the only resolution we could come to is that it is obvious that the two
straddle faces should have negative draft.
I hope the test is as obvious because if I rely on SW I may get an answer wrong...
Can you upload your part having the parting lines you've created?
Thank you for the video but when I play it back the screen is broken up and I cannot tell exactly what you are doing.
I pick Parting Line, Select the Top Plane, Set the draft to 1 deg, Check the Split Faces box (Use for Core/Cavity split is already checked.)
I then pick the Draft Analysis button, The Parting Lines box populates automatically. (I have also removed them all from the box and selected manually then picked the propagate icon), picked the check mark then run Draft Analysis. 2 straddle faces.
Here it is.
Video runs fine for me, so it might be missing codec on your side. Are you using window media player?
I was using VLC. Using Windows Media Player it does play just fine. <Thanks>
I am doing the same steps to create my parting line...
Looks like your system is not able to import the file correctly. Can you try the steps on this part?
I will have to get back on this....
I will respond asap..
This one worked correctly. I got 17 Negative Draft Surfaces/Faces with no straddle faces...
That is good (but I don't know how that helps with my concern about downloaded files...) :-\
especially whee the exam is concerned...
Please reinstall SOLIDWORKS and check again.
Not looking forward to that...
Gonna have to work out scheduling that with my work responsibilities....
It may be some time before that happens. :-(
I have the same issue. I am running 2014. The previous question (question 1) answered perfectly, but I get 15-NEG and 2-Straddle for question 2. Changing the draft from 1 degree to 2 degrees gives me 17Neg, 0Straddle, but the question demands 1degree.
This doesn't feel like a uninstall/reinstall software problem... Is it a glitch in the question? Any insight would be appreciated as I too would like to take the MT exam soon.
Could be issues with your templates or file not importing correctly. Can you try the file from this post: https://forum.solidworks.com/message/665070#comment-665070
Thank you for your reply.
Initially, using the bracket from the thread gave me the same result 15NEG/2STRADDLE. However when you said "importing correctly" it gave me the idea to change the way I imported it. I previously had blindly accepted "Feature Recognition" (although I don't fully understand what it is doing) when I imported it.
I discovered that when I use "Feature Recognition" I ultimately end up with 15NEG/2STRADDLE as my answer. If I choose "NO" to Feature Recognition then I ultimately get the correct answer: 17NEG/0STRADDLE.
I would be interested if someone else can duplicate this to confirm the solution. Thanks for steering me in the correct direction! -mike
Yes that is correct. With "Feature Recognition" set to yes, these two faces gets messed up.
So the key is to not change anything on the files until asked in the exam.
That is exactly where I was getting my Straddle faces. Thanks for confirming.
I used your "bracket" to find my problem and get the correct solution. To be through, I did the same thing with the Solidworks, directly downloaded, version. Unfortunately, I got the same 15/2 answer regardless of applying "Feature Recognition" or not.
I am simply using the Open Command in SW2014 to open the original version of the file "Bracket.x_t". Should I be doing something different?
Check if this message is listed under dismissed messages (refer picture below). If yes then select it and click OK. Then reopen the original file and you should be prompted for "Feature Recognition". Select NO and see if that resolves the issue.
I have three unrelated messages, but not that message or anything that would be related.
Not that I fully understand it, but I did a "compare documents" between your .SLDPRT part and the original, (no Feature Recognition on open), .x_t part and it reports identical in both Volume and Faces.
I would love to determine the answer as to why this happens, but also I am wondering if the Mold Test will supply proper SLDPRT files or will they be of some kind of file like the .x_t? In other words, am I safe to take the test or will I run into this problem on the test?
I'm not sure as why you don't get Feature Recognition on file opening. Could be related to student version you are using but still no confirmed.
The test could have any kind of files, so key is not change anything. Like in this case, do not use Feature Recognition. And then all should be good to take the test. Bets of luck.
I have an additional question related to the Mold Exam. I expect a question which requires repairing broken surface geometry and that that geometry may not be solid. I have studied: Knit Surface, Thicken, Delete Face, Intersect and understand them and can use them.
My problem is that the geometry I'm working on now is a single imported surface. I don't know how, or if, I can (or should) split the single surface. Therefore I am having problems on how to proceed since it seems that those tools mentioned require multiple surfaces to work on.
I have attached a simplified version of my problem. The part is hollow and needs to be made solid. Any solutions or pointers to instructions would be greatly appreciated.
Simply use the thicken command and select this option
I'm also facing this problem with 15 negative surfaces and 2 straddle surfaces on SW2017. Did not perform feature recognition. Very worrying if this happens on the actual exam.
