# Im really begining to hate this book

Ok, so this book is explaining nothing to me. Here is the instructions from the book. On opposite side is just a picture of what we are supposed to be drawing. Been here 2 hours and nothing so far. My drawing will not fully define for the life of me. There are two dims in the instructions I don't understand. Both involve holding the shift key but it is never explained to me what the shift key is doing....

I'm ready to burn this text book and find a better book that actually Explains to me why I'm doing it. All I feel like I'm doing is being a robot without knowing why...

Thanks. I'm going to go home very soon and pretend I don't have to use this book haha

• ###### Re: Im really begining to hate this book

also, cant seem to figure out what author means by parrell 2x.. does that mean to add a relation for those two lines twice?

• ###### Re: Im really begining to hate this book

Hello Matt,... try to post something so we can get started with what/why/where.... it is going wrong?

...so, regarding your book and page... I'll attach a link for others here..

• ###### Re: Im really begining to hate this book

I just noticed your name is almost the same as the author, that scared me because I'm not trying to be a hater. Everyone learns different. I mean I teach calc 1 and other maths everyday and In math, knowing exactly why we do what we do is important.

Thanks for posting the link.

• ###### Re: Im really begining to hate this book

No problem.. and btw, I do not know the author.

• ###### Re: Im really begining to hate this book

Holding the shift key down will allow you to dimension to the edge of a circle,

other wise it will dim to centre of arc.

the bottom dim that says hold shift key is not needed

• ###### Re: Im really begining to hate this book

Ned... your amazing. If the book would have said that, I would be ok:)

Ok, for the parallel relations, that is what I did.

Now regarding that bottom dim, what is it measuring from? 1.25 from where?

Is there a better book than this? Professor says I can get whatever will help me out

Thanks

• ###### Re: Im really begining to hate this book

I believe that dimension should come from the horizontal construction line, that you will revolve the part around,

and thus creating a hole in the middle of the pulley.

• ###### Re: Im really begining to hate this book

Arg, did I miss that in the instructions? I hope this is not like the plane issue I had haha

Thanks

• ###### Re: Im really begining to hate this book

Not sure, the dim in picture goes to nothing so had to assume

Does that include changing to a class section (or school) where the instructor actually instructs?

This is pretty basic stuff that I normally cover in my classroom lectures.

• ###### Re: Im really begining to hate this book

I wish i could. Where i live, the university up here does not offer the class. How it had to be done was going to a local tech school, registering for a 50 hour section where you read the book, follow the book, and ask questions. The instructor does not give a lecture. You just read book, ask question.. BUT, i have never given up on something so i am going to make sure i get those 50 hours AND i ask ALOT of questions to the instructor. I know it annoys him but i dont care. I want to learn.

It would make a world of difference if each new lesson, the instructor went through a run down of the part.

• ###### Re: Im really begining to hate this book

Never forget that your instructor is paid to teach you.  That is literally his/her job.

• ###### Re: Im really begining to hate this book

Exactly, thats why i ask so many questions, but yet still feel so lost.

Oops!

Well, in my classroom I display on huge screen as I go through lecture demonstrations.

Those who sign up for the class get a better view.

• ###### Re: Im really begining to hate this book

Matt Thomas,

Any video from J. Mather will be instructive. Otherwise, I want to point out that youtube is generally considered a bad resource for beginners.  If you get directed to specific videos, those will probably be fine.  But, don't go searching on there for things until you get a little more experience and can sort the good from the bad.

• ###### Re: Im really begining to hate this book

i agree, i tried that a few months back with something and i was blown away by so much incorrectness, for lack of a better word. All i know, in the 5 min video from J. I was able to FULLY define my sketch, learned 5 new concepts, and now have an almost complete part.

On a side note.. i am trying to figure out why my part would never fully define. I personally think it has something to do with the 1.25 dim. What i did was drew a line under the orgin, then dim'd to that by picking the lower left endpoint of the part and then the end point of my new line i drew, typed in 1.250 and hit enter.

when i revolved the part, it LOOKED fine but the total outer diameter was off by an 1.xx inches. Even though on my skecth all the numbers for the dims were correct, i bet placment of said dims were off.

but now, my part is fully defined and works.

thanks

Matt,

I would have placed the line on the origin. That way when the revolve feature was completed the Origin and thus a fully defined axis would be at the center of the revolved part. That would also probably have fully defined the sketch.

The shift key would help setting the dimension as diameter dimension OR dimension on other side of construction line without the need to move the cursor

• ###### Re: Im really begining to hate this book

Thanks. I promise I'm not trying to create drama and I know I'm new at this, but it gets frustrating when I am brand new to solid works and the book makes BIG leaps to somewhere that I have no idea haha. I double checked the instructions and it does not mention a constru tion line anywhere. I thought of putting one but thought that was bad practice haha.

If the book store takes this book back, I'll need to buy something else. Any recommendations?

Thanks again

• ###### Re: Im really begining to hate this book

I've seen many other books from the author Paul Tran and I can definitely recommend his books. But I do agree with you for that 1.25 dimension there should be indication of how to get/add that dimensions.

Can you check previous pages if he has mentioned anywhere about dimension across a construction line?

Matt Thomas wrote:

I would also recommended Matt Lombard's SOLIDWORKS books, they are just awesome!!. And if you can wait for some time, his new edition "Master SOLIDWORKS" is expected soon.

And in case you looking for online video training, then I would highly recommended MySolidWorks and SolidProfessor.

MySolidWorks has lot of learning eCourses related to SOLIDWORKS and its related products. This is a great learning resource.

SolidProfessor offers a free basic account with 5 lessons and then you can opt for paid membership. They offer various learning tools under same membership.

• ###### Re: Im really begining to hate this book

Hi Matt,

Ned Hutchinson has already explained you the reason for holding shift key while creating dimension for circle edge.

In regards to create the dimension 1.25 shown in the bottom left corner of the picture: Select the horizontal construction line and the line where you want to create the dimension 1.25 and then hold the shift key and move your mouse below the construction line and place your dimension. Type the value of 1.25. This dimension works as a diameter as you will revolve the sketch around the horizontal construction line. It should have been explained properly in the book.

Hope it is clear for you.

Regards,

Nilesh

• ###### Re: Im really begining to hate this book

Yes I did see his reply:)

No other pages in this edition of the book talk about construction line dimensions, nor does this lesson for the pulley mention to use a construction line. Just a lot of assumptions are made and since I am new, I'm not able to follow the assumptions or make a judgment call that would be considered good practice.

Bad practice does not make perfect haha and that how I feel atm.

" it should have been explained properly in the book" I agree but it was not. The supplied image I attached is all it gives me to learn off of. The pages before that were the center ball joint part where I created the wrong plane haha.

Matt, I believe you will resolve a LOT of your frustration if you go through the built-in SolidWorks tutorials (under the Help manu).  These are very well done and will teach you some basics that the book is assuming you already know.

• ###### Re: Im really begining to hate this book

I'd also suggest using the built in tutorials. I taught myself to use Solidworks mostly by using the tutorials.

Granted I did hand drawing in the BC (before CAD) days and used AutoCAD and Inventor prior to coming to SW, so I had a big head start on you. However, the tutorials will at least help you get a handle on some of the basics.

• ###### Re: Im really begining to hate this book

I totally agree. If you have access to the software, tutorials are included and available. The tutorials are pretty good. Run through those, ask questions here, and ignore the books until you've got basics down.

I suggest learning the Search window for commands and help. This will be a handy and fast cross-reference.

I could suggest ignoring the class, but you're probably getting a credit for it. Learn what you can however you choose, and complete assignments. The assignments aren't the takeaway, but the learning is.

• ###### Re: Im really begining to hate this book

Maybe i should hold off from the book for a week or so and do all the tutorials in solidworks. I did the presure plate one and i feel i learned alot from that tutorial.

thanks for that reply and encouragement

thanks to all for the encouragement

• ###### Re: Im really begining to hate this book

When I saw this topic, the first thing I did was panic because I thought it was one of mine. Writing tutorials for people when you can't look over their shoulder in a program where there are so many options is very difficult. Especially if they aren't video tutorials. It's easy to make the assumption that someone has sketch relation display turned on, or that they know how to use dynamic mirror in a sketch, or the tricks to make tangent arcs. I struggle against this all the time. The alternative is that you write a tutorial that's 20 pages long and has so much irrelevant information in it that you forget what you're doing long before the instructions are over.

My one recommendation to people buying books (anybody's book) is that you have to approach it with a lot of curiosity. If you wait for even a book to spoon feed information, you'll probably be disappointed. You have to poke around and assume the writer is human. Maybe you can't learn exactly what the writer intended, but you can learn something. I try to do tutorials twice or more. The first time straight by the book, if possible, the second time I try to experiment and find the limits of the function being explained. That way I take more from the book than was ever intended in the first place.

Also, there is a base level of knowledge that you have to have going into these things. The Parallel 2X is standard engineering notation, although the application in this situation is questionable. I would have had the reader mirror the sketch. Trying to create a symmetric sketch without mirroring is insane, and you might even mirror about 2 axes.

Anyway, cut the guy some slack. Writing books is hard and pays next to nothing.

• ###### Re: Im really begining to hate this book

Oh i agree with you. in one of my posts up above, i state that im not being a hater, just frustrated and feel like nothing is being explained to me at all. I know writing tutorials is a pain. I had to write calc and chemistry curriculum all the time in my last job. I know some who hated my work and others who loved it.

"If you wait for even a book to spoon feed information, you'll probably be disappointed. "  this is probably what my brain is looking for. If you have ever had a strenghts of materials class or a thermodynamics class, the first 2 or 3 weeks, we get spoon fed because we have noo clue what we are doing and it can cause a coma haha.

i do try to approach with an open mind, but what stops me is not knowing if what im doing is good or bad practice because i have no guidance. The book says to use shift key while placing a dimm, but never tells why, so i started holding shift on every dim because i thought that was the correct way, until i noticed only certain ones had it, but couldnt figure out why haha.

still cant tell a difference when using shift, nothing changes with the mouse cursor or where it positions the dim

I am going to try and finish this part in the next 5 minutes. then do the in house tutorials from SW

thanks Matt.

dang, still no go. hmm, we have about 15 students who use this PC im on. could some options have been turned on or off? im leaving the school atm to go visit the DEAN of this class. I need to switch campuses or something. there is a campus about 45 miles away that apparently has an instructor there that can help me out. to me, its worth the drive through the canyon to get there and LEARN

• ###### Re: Im really begining to hate this book

Matt Thomas wrote:

There's no reason to hold down Shift while placing a dimension unless you're trying to dimension to the edge of a circle or arc.  See How can I dimension to the edge of a circle or arc instead of to the center?.

• ###### Re: Im really begining to hate this book

exactly:) thats what i am saying. in my version i am using, i can hit smart dim, select my point, then without hitting shift, i can select the top edge of the arc and it will dim that for me. I just showed up to the other campus and they are using 2015 vs 17, and i have to hit shift or it will put the dim from center of the arc. Im guessing in 2017, the smart dim is smart enough to infere where i want itand thats why i couldnt see the benifit of hitting shift.

Iam still trying to get the R and the D to show up now. Im looking through system settings to see if i can force it

• ###### Re: Im really begining to hate this book

That's weird.  It should automatically show either a diameter symbol or an R before the dimension.  I'm not sure of a way to turn that off.  You can switch the dimension between radius and diameter by right clicking on it, choosing "Display Options" and choosing Display as Diameter if it's a radius, and vice versa.

• ###### Re: Im really begining to hate this book

here are some pics, i still cant get the R or D to show up or the diameter symbol to show up when i place said dimension.

here is what it says it should look like:

Still no R or D on the cursor or symbols. Even after i place the dim, still nothin. From what i have read, it appears AFTER i place said dim.

My display options on right click are different. i know that option you show exists, but its in a different location that i am going to go hunt for.

if it is just a lack of my understanding, i do apologize. i am not doing this on purpose to be a jerk. it really is that the settings on the SW 2017 are constantly messed with by students

thank you much. I am doing my best:)

Use SOLIDWORKS Rx tool (should be already installed on your machine) to capture the video

Ok, i reset all the settings back to default, installed ispring8 before i read Deepak's post and here it is...

• ###### Re: Im really begining to hate this book

..so,.. yeah, the Diameter and Radius symbols do not show up during the sketch... but after the feature creation or after the feature resolves.

• ###### Re: Im really begining to hate this book

yeah thats why i was confused. because in the help link, it made it sound like they were supposed to show up after i place the dimensions. It didnt mention that it was after the sketch was revolved. It did say its helpful for revolved parts, but i thought the drawing they were showing was the initial sketch haha. my bad

• ###### Re: Im really begining to hate this book

Matt, I have submitted the issue of the 1.25" dimension with SDCPublications and here is what has been updated: SOLIDWORKS 2018 Basic Tools: Getting started with Parts, Assemblies and Drawings Errata Page

And as I see your video, I can see the D and R on your cursor.

• ###### Re: Im really begining to hate this book

yup, it showed up after the settings were all reset to default. i was hoping you would see that in the video.

thanks for submitting that:)

thank you much. I am doing my best:)

Let's address the last thing first:

For the settings issue you have a tool available that might just solve your problem.  Look into using the Copy Settings Wizard.  Once you get the settings the way you like them you can save it out somewhere (recommend with your name/initials instead of the default file name) then reload those settings the next time you log on.  You can even take this settings file with you on a thumb drive or cloud storage and use it on other seats of SWX.

For the diameter to show up the feature must be a revolved item.  I just did a similar sketch and the doubled dimension in the sketch shows just as yours does, without the diameter symbol.  But as soon as I revolve the feature and then re-edit the sketch the diameter symbol is there.  This makes sense because in the initial sketch the dimension could be for a symmetric feature.  They are not really diameters until that sketch is used to create a revolved feature.  So what you are seeing is indeed the intended behavior.  Frankly, it is pretty smart because once the sketch is used in a revolved feature those dimensions acquire the diameter symbol.  Cool!

• ###### Re: Im really begining to hate this book

thanks for letting me know about the settings wizzard. thats actually a very smart idea from SW.

this is what i was following. I did notice at the top it says its helpful for making revolved sketches, but i took that as the sketch BEFORE the revolution was applied. Maybe i am drawing the sketch wrong.

Is there a difference between:

New part> Sketch>front plane>(draw the sketch)>smart dim>features>revolve

Versus

Newpart>features>revolved boss/base>front plane>(begin sketch)>smart dim>green check mark

the book always has me start a new sketch, never a new feature then begin sketch like the SW tutorials show.

There is ultimately no difference between these.

Personally, I always create a sketch first and then select my feature.  My mind flows better that way.

I know of other people who select the feature first to allow it to automatically create the sketch.

I like to pre-select a plane or surface, then the feature.  That way a sketch automatically opens on the selected plane, and when exiting the sketch I'm immediately taken to the feature's Property Manager.

Matt, the short answer to your big question regarding the display of the diameter symbols is that what you are seeing is the correct behavior.

With regard to your question above, there really is no difference.  One of the beauties of SWX is that there are usually several different ways to accomplish the same thing.  My own preference is to always start with a sketch and then to tell SWX what kind of feature it is going to be when I close the sketch, but there are others orders of picks that will achieve exactly the same results.

• ###### Re: Im really begining to hate this book

yeah i just revolved the part, went back into edit the sketch and the diameter symbol was there.

All i was doing was following the link above literally and exactly. i did not know that i had to go back into the sketch that was all ready revolved to see that symbol show up. I thought that by placing it on the other side of the center line automatically told SW that it is a diametrical dimension.

Still working on getting the D and R to show up. I am going to reset some settings and see what happens

thanks very much. I am learning. I just did not know that in the link above that they had previously drawn that and were editing the all ready revolved part haha

The option for dimension across centerline work in SW2015 also and even older version without need to press shift.

And there is no setting for the R and D to show up. They would appear once you add the first radius/diametrical dimension and would stay on until you press escape or end command.

• ###### Re: Im really begining to hate this book

TO ALL:

Thank you so very much for the help, the understanding, the PAITENCE, the kindness and appreciation you have shown me. Without you guys, i would have quit this class. I am leaving to go to another campus that is through the canyon. I know J mentioned this and i told him that the university does not offer a class and im a t a tech school that does things a little different. However, i did call the DEAN of this class and i am going to be working with him from now on. That means a 45 min drive through a canyon to his office... BUT I DONT CARE I WANT TO LEARN.

thanks

• ###### Re: Im really begining to hate this book

Matt,

Good luck.  Just a little tip to get you on the way.  Read the whole page before getting frustrated, and then read it again.  Lots of the drafting programs will have some kind of hint what to pick on somewhere on the screen.  It gets easier as you start to know what to do and in what order to do it to get the results that your looking for.  Just be ready to change it up some when you get the repeatable crash.
