Analyzing and Fixing an interference In SolidWorks
Before finalizing a design, you must do an interference check and resolve all interferences before going to the prototype stage. That is the main purpose in creating assemblies in parametric software. One of the assignment I have student complete has a screw with dimensions that create an unwanted interference. I made this video to show them how and why to analyze an unexpected interference before submitting work for my evaluation, but it is an even more essential skill in the field to reduce the costs of proto-typing.

New Glitch in AutoCAD When Solving one of the Puzzlers
มุมมอง 1887 หลายเดือนก่อน
At one time the Defpoints layer was the only non-plot layer in AutoCAD. Old school users of AutoCAD would sometimes use the Defpoints layer that is created automatically when any dimension is inserted to hold the points used to define dimensions as a way of placing entities in a drawing that won't plot. For may years it has been possible to make any layer a non-plot layer, but occasionally an o...

Hello sir thank you for sharing this video and give us great time . I have an issue arises the backup folder in C: I can't find it. In C drive where it will be ? .
The default location is C:\Users\user\AppData\Local\Temp\SWBackupDirectory. However, you can change that in options --> System Options --> Backup/Recover --> Backup. You can also set it to delete backups after a certain number of days. The default is 7 days.
@DanAbbott-SMCC thank you so much now it's solved a lot of thanks for your great efforts .
Dan Abbott. Thank you. You are a life saver.
Wow. So glad you're still breathing!

do not touch the cubs
We were there with several wildlife biologists, all experts at dealing with bears. The cubs needed to be held during the process to keep them warm and comfort them, and there is no evidence that holding them has any negative impact. They certainly wanted to be held. I'll go with the experts on this one.
thanks. very helpful.

Thank you for this awesome video!

thanks man i am not getting my marks deducted in my assignments ever again!
You're welcome. Glad it was helpful.
Helpful tutorial, with this, can i take the CSWA exam?
Well, yes you can, but I can't guarantee that you'll pass. You would probably need to use the software to create other parts and assemblies for which there is no video and be able to take a timed test without being intimidated. Even experienced users can get hung up on one part and run out of time. I do recommend doing all the assembly questions on the exam. Since they are at the end of the exam, users often don't get to them because they keep trying to complete a part in the earlier stages. Since the assemblies are worth more on the exam, and -- in my opinion -- are easier, you might want to start with them since you can go back to earlier questions at any time.
Thank you kind sir, this was useful.
Glad it was helpful!
Thaaaaaaanks!!!!!!
You're welcome!
Thank you for sharing your knowledge and experience.
My pleasure!
Very informative video! Just to clarify, is light blue deeper or shallower than blue? I think you mentioned that light blue is shallower than blue.
On some charts a dark blue is used to denote deeper water than light blue, but the chart I used doesn't use dark blue. There is a weird sort of blue/green that denotes very shallow water, but I wouldn't call it a dark blue. It is between blue and mud color. At any rate, the key is to pay attention to the numbers indicating depth. Use the colors to feel confident when you are in an area colored white -- unless you are in a tanker, you'll have plenty of water there.
Googling "Script that pulls linework out of multiple dwg at once" returns this video with <1k views... People really don't try and utilize the power of scripting in Autocad. Great video, and very inspirational that you've been doing this for longer than I've been alive. I've got a small amount of experience coding, and I am tasking myself with creating a database of my Land Surveying firm's linework, C3D Cogo points, and whatever it is Microstation uses (very new to that software which doesn't even use LISP but does use VBA). I'll be exploring your channel, definitely buying your book, and utilizing whatever resources you'd recommend. Thanks for putting this content out there!
Loved this video very helpful. Quick question, does this exam format still follow today’s testing guidelines? Or has anything changed since the video
There has been no change in the exam for the past 12 years I've required it. Glad you found the video helpful.
AutoCAD user since 1996. LAYER STATES WITH THE CHECKSTANDARDS COMMAND: In the company that I work for, we use layer states for representing different customer’s equipment on our telecom towers in the UK. We _also_ have a standards file (.dws). I cannot successfully work the .dws file with all these layer states in place. I am thinking, “Which layer state do I choose as ‘current’ before I implement the .dws file with the CHECKSTANDARDS command so that the drawing is corrected to ‘standard’”? In the Layer States Manager dialogue box, all the ‘layer properties to restore’ are ticked/checked except ‘Transparency’. When I implement the .dws file the first time, it makes the corrections. When I implement the .dws file the second time, it shows up as 0 problems all round. Excellent! Interestingly, when I reselect the layer state as before and then implement the .dws the third time, I get the same problems as before! Am I thinking correctly that we need to create a .dws file for every layer state used in the drawing, else implementing one drawing standards file (.dws) is useless? Thanks in advance. 😊
I think you are correct.
Thank you so much !!!
You're welcome!
Amazing clarity. Thanks, Dan.
My pleasure!
It doesn't matter what release of SolidWorks you are using for this assignment.
great work
Many many thanks
Fantastic video! I'm taking the CSWP soon and this was incredibly helpful for seeing where I missed somethings in the practice exam. Thanks for making the video!
Glad it was helpful! I plan to do another that covers the configuration and assembly part of the exam, but haven't had time yet. Make sure you have some experience with configurations and you might want to review the various mate tools, although you're not likely to get any questions on the mechanical or advanced mates. The width mate will probably be helpful though. Good luck.
Hello Dan, new to boating and working on improving skills interpreting charts. I sometimes get confused on understanding non laterally significant buoys. Sometimes they are green, sometimes red or other colors like black STAY CLEAR). On closer look you can see the hazard or area of concern on the map. I often default back to interpreting the color for safe passage, which isn’t always the case. Any guidance would be appreciated. Also when I’m certain a buoy has lateral significance (like a Green Day marker..not a buoy actually) I always want to see a related red marker which is very often not found. So leave the green on port when returning and safe water assumed on starboard to some reasonable boundary ???
Randy, Sorry not to get right back to you. I haven't checked my comments in a while. You ask a very good question, and I hope a lot of people will see my answer. The only way to know for sure how to interpret the purpose and meaning of aids to navigation is to ALWAYS have a current nautical chart with you -- either on paper, digitally (preferably on a chart plotter), or both (my preference). There are plenty of cell phone apps that can be used as a nautical chart plotter, but I always download a PDF of the largest scale, current chart from the NOAA website and print it on a large format printer. I then put in in a large plastic chart bag and fold it up so I can unfold the bag to read any part of it. You probably don't have a large format printer available, but you can print it out in pieces or buy a paper chart from an aftermarket service. A lot of students in my navigation classes start by thinking that "red right returning" is all they need to know about navigating, but as you point out, sometime buoys have lateral significance (they mark one side of a preferred channel) and sometimes they don't. Even if they are laterally significant, in congested areas it may not be clear if you are leaving one port or returning to a nearby different port. Not only that, but sometime -- as you indicated-- a buoy is laterally significant, but the "other one" isn't there. That often happens with daymarks. The best advice then is to look at the chart, but if you don't have one, stay close to the day make leaving it on the correct side of your vessel, but NOT TOO CLOSE. The daymarks are often embedded in a ledge that extends a bit beyond the day mark. A lot of bottom paint has been left on ledges like that. There is safe water on the proper side, but you may have to leave that "reasonable boundary" you mention. The other thing is that floating buoys can move in storms. They have an anchor (usually a mushroom anchor) and that can be dragged in extreme circumstances. I have also seen buoys pulled under by a strong current (the inside passage between Bath and Boothbay Maine is one common spot), only to suddenly shoot up above the water. You don't want to be over it when that happens, so knowing where a buoy should be by looking on a chart and giving a "reasonable boundary" is also a good idea in areas with strong currents. And just to make it even more concerning, I was once going between Harpswell Sound and Potts Harbor through a passage known as the "snake pit" -- which requires paying close attention to the laterally significant buoys that guide you through the serpentine passage with ledges on both sides -- when I couldn't see the green can #3 that was always there. When I slowly approached where it should have been, I could see the top of it about a foot below the surface. The gear holding it in place had gotten twisted up enough during a storm to be too short to allow the buoy to float above the water line. I immediately contacted the Coast Guard to alert them and they sent out a boat to fix it so no one would run into it. A lot of local boaters love whipping through at high speed for fun. Not much fun if they'd hit the very large steel can. This probably qualifies as my longest reply to a comment, but I am always interested in people learning why "red right returning" is not all they need to know about navigating. Now add some fog, and it gets even more interesting.
@@DanAbbott-SMCC thank you ! Helpful kind of :). Much appreciated
My pleasure. I understand your confusion. The reality is that it is much easier to mark passages on land than on the water! Good luck with the boating. Mine has been sitting on it's trailer all summer while I deal with a herniated disk, so I am very envious of those who have had a boating season. Mine is likely to consist of the first three weeks in October!
@@DanAbbott-SMCC Sorry to hear you’re having back issues. I hope you get relief soon to enjoy some boating season. We are having a great time on the water. As I mentioned being new to boating I have so many things to learn, practice and develop proper skills to make our adventures even more pleasurable and above all SAFE. Please let me know if any learning opportunities come up ( on line classes, discussions etc) that I may benefit from. Be well !
i wanna ask a question, when i save as from q1 to q2 and change the equation followed by example question i get different results. But when i build part from 0 i get correct answer.
I am not sure what your question is. You would get the same results if you applied the equations correctly. The biggest problem that people have with global variables is that they type in the name of the variable rather than select it from the drop down list. If you type it in, the variable isn't linked, so the value is used but changing it in the equation editor won't apply to the part. Unless you see the Greek letter Sigma preceding the value in the dimension, it isn't a linked global variable.
Thanks. Making that ref. plane normal to the helix was the trick. very nice expiation. I agree with @mostsoot it does sound like a 3D printer printing a curved or circular outer/inner wall. Ha. ("inexpensive" stepper motor resonance is pretty obvious...) I actually thought the same when I first watched your video... :) Anyway, the dimensions on your trapezoid are for LMC (largest hole) conditions? Nominally, that root depth is 0.5 * pitch (0.5 * 1/6 = 0.0833 - you use 0.0933)?
You're welcome. I am not sure what that noise is, and I agree that it sounds like a 3D printer. I have 10 printers, but they are at work. I made this video in my home office, where I do not have a printer. The only thing I have in here that makes noise is two EGO battery chargers, but I wouldn't have made a video while charging those batteries because it is very noisy. Perhaps some radio frequency problem? I found some differing dimensions for acme threads. I think I used the Machinery's Handbook, but can't remember anymore and it may have been a typo. Obviously, you could modify those dimensions. The purpose of the video was just to show a student how to create a thread using a profile and a helix. The thread tool in SolidWorks doesn't always give a true thread in my experience, so when I do want to create one for 3D printing something with a thread, I usually create the thread this way and reduce the size of an external or increase the size of an internal thread and modify it if it doesn't work.
Thanks for the well-explained tutorial ✌
Glad it was helpful!
Ok, a question, when i open a simple part and i wanna find location fast, how i do that?To be able also to copy that location path etc...?
I'm not sure I understand your question. Do you mean open a single part directly or from the assembly? If from the assembly, you can use SAVEAS to see the current path.
@@DanAbbott-SMCC I found, to be able to find fast the path... and copy the path... File -> Find references... and you can assign shortcut to this also.
Thanks for sharing Daniel, I think this is much better than the design table. But is there a way to use this configuration feature table in drawings? There are definitely some issues with the design table in drawings and I'm looking for a more robust and reliable way of putting a configuration table into drawings.
What a good question. I don't know, but I'll try to figure something out.
THANKS FROM 2024! ILL CHECK IT OUT! REALLY COOL YOUR GRANDFATHER PUG MONEY FOWN ON A TUCKER!! (It wasn’t made because the BIG POWERFUL CAR MAKERS OF THE TIME FELT THREATENED BY THE INVENTOR!! And one of them came out a few years ago with HIS CENTER HEAD LIGHT INNOVATION THAT FOLLOWED THE CAR LIGHTS & CLAIMED IT AS THERES! When NO! It was not!!
The Tucker wasn't on the floor a couple of weeks ago, but they still have it, so it will be back. Very cool collection. I took my 90 year old mother-in-law, and she loved it. Then I took my 11 year old grand nephew, and he loved it. You should go.
wonderful sir
Thank you. Glad you found it useful.
I have followed every step and checked it perfectly but then also in question 2 I didn't get the exact answer which you got (1st question is correct) can you please provide any solution ??
Not without seeing the model. The most common error people make on this part is assuming that both cylinders are the same dimension. One is based on X the other on Y. You might check that. If your answer is within 1% of the correct answer given, it would be considered correct on the exam. I have gotten the same answer each time I've gone through this practice exam for a class, so I think you probably overlooked something. You should also check for any under-defined sketches. If you have any, correct that and see if you get the right answer.
Thanks for the (- trick to find under defined sketches it was exactly what i was looking for for my project
You're welcome!
Thank you, The video was easy to understand
Glad it was helpful!
For CSWP, is this the pattern of questions asked? 3 questions with same figure and rest 2 questions with same figure?
Yes, but there will be more than one part to start with. But each part has multiple questions after editing. Part 2 of the exam has you opening and modifying existing parts and managing configurations as well. Part three involves creating fairly complex assemblies from existing parts and possibly parts you must make.
thnx alot pops
Any time sonny.
Thank you so much, I really strugled with this...

Pretty sure this was a final exam at some point around 2011.
It is actually from a project I assigned in my first class nearly 20 years ago based on an illustration in my favorite drafting textbook at the time that was illustrating conventions for section drawings that deviated from actual orthographic projection. But, yes, it certainly has elements of parts I've seen on the CSWA exam since. That's why I included it -- to make sure people are prepared for something like it since the practice exam doesn't have a revolved part. Each of the major projects assemblies I assign now have parts that require a revolve.
Perfect example of how small changes such as specific selections of sketch planes, use of offset geometry instead of manual sketching, and changes like extruding with an offset instead of in two directions at once (for the cylinders) actually results in a change of mass and the difference between the right and the wrong result. If you're off by a few grams or decimals in your answers - watch this end to end and make the changes in your methods checking the weight difference as you go.. Thanks again!
Thanks for your comments, and you're welcome.
This video helped me more than my actual teacher did. thanks!
Glad to hear that it was helpful. I'll have to watch it again. Don't be too hard on your actual teacher. I've gotten better at it over my 40 years in technical education, and composite profile is a bit tricky.
