 my new love he's got the intellect yes he's got the mind of hey there so hello and welcome to episode three I promise that we were going to do a little bit of solid works stuff today so let me just go ahead and open that up and I brought some parts from the last bag that we filled so let's just dive right into it the first thing I'm going to do actually is let me close that and make a folder for all the Monroe F parts okay so I can save everything in there so the easiest part to model is a washer so I'm going to take the the rather the larger washer and model that so I'm just going to create a new part okay and we get this basically blank screen so the first thing that we need to do is sketch out the base of the washer so what I'm going to do is I'm going to open a sketch and the first time you open a sketch it asks see what plane do you want to draw that sketch on I always like to choose the top plane so I'm looking down on the part okay so I'm just going to measure the washer with a with my calipers so it says point five oh five inches it's probably you know actually half an inch but I'll just go with point five oh five so I'm going to select my circle tool and I get two different circle types one I can specify the center point and then the radius and the other I can specify three points and it'll draw a circle so I'm just going to use the center circle so I'm going to snap to the central point click and draw out a circle it doesn't matter how big it's going to be because now I'm going to go to the smart dimension tool and I'm going to click on the circle and I'm going to tell it what its diameter is and it was 0.505 inches my my solid works is set up by default in inches and set up by default to display three digits of precision if you don't know how to do that check on the web anyway that's it that's my base so now I can exit the sketch okay so I've got this circle so now the next thing I'm going to do is go to features and I'm going to extrude that sketch so basically I'm going to give it a third dimension so basically on the left side it's asking me how thick do I want that washer and I'm going to measure the washer thickness and this says 0.064 inches so I'm just going to select here 0.064 inches and the type is basically blind I'm not actually going up to a particular vertex or a surface I'm just you know saying blindly extrude this this to 0.064 so I'm going to click the check mark and there it is so now I think it's alt that I press yeah so sometimes it's a little hard to remember all the various keystrokes so so there's the the basic shape of the washer obviously it doesn't have a hole in it so what I'm going to do is I'm going to put a hole in it so I'm going to here is my view orientation so I'm going to look down at the top there we go and I'm going to draw another sketch and it asks me to select a plane or a face or an existing sketch so I'm just going to select this this plane I could always open up this little thing and say you know what plane I actually want on it but in this case I can just click on that plane so now I've clicked on the plane so basically I'm drawing on the top side of the the big extruded circle I'm going to select my other circle tool I'm going to draw it out doesn't matter how far and then I'm going to select the dimensioning tool and dimension that circle so now I have to find out with my calibers how big the inner hole is and my calibers say it's point one six five yeah point one six five so point one six five done so I exit the sketch and remember sketches are always two-dimensional things so of course if I look at this basically that circle is simply drawn on the little blank that I've got here so now what I've got to do is I've got to make this circle cut through the entire thing which is another feature and I'm going to select extruded cut which basically means I'm going to take my circle and extrude it just like I extruded the base except this time it's going to cut and basically I'm telling it to cut blind I can't I don't want to cut blind because then I have to specify how far I want to cut down instead what I'm going to do is I'm simply going to say cut through all okay and that basically means I start from here and cut downwards through all you can actually change the direction that it's going to cut or you can say through all in both directions and then it'll cut in both directions but in this case I'm just going to select well okay through all both hit okay cannot locate end of feature well that's nice so let me stop that and start over with sometimes honestly solidworks does a bunch of things that make no sense to me so there it is through all hit okay and there it is I've got a washer and that's it that's all there is to modeling a washer or modeling this particular washer so I'm going to save as so I get to specify see where's my folder here we go one row F parts so I got to give it a name so I'm just going to say that it's a washer from bag 5 big washer from bag 5 at this point I don't really know what to call it you know I would give it a part number but right now I haven't really designated which part is which so I can do that later so I'm just going to call it that I'm going to save it and I'm done so now if I wanted to I could export it into different properties into different formats so I would do another save as and then I can select any one of these STL as I explained before is good for 3d printing 3d printers basically use STL the only problem with STL of course is that it's made out of triangles and the sides of the triangles are flat which means you can't do arcs all is not lost however because if you do click STL you can click on options and then you can you can see what the tolerance of the parts are going to be so this so basically we're seeing that for course resolution the tolerance is point zero zero zero eight which is basically about a foul and that basically means that any point on the circle any point on the actual part the the STL version is going to be no more than a little less than a thou off of the actual circle you may not want that you may want fine which gives you three tenths of a thou or you can select custom and of course the more the more triangles you have the better your tolerance so for example if I go to course I have 248 triangles with only 70k if I go to fine of course fine I get about 50% more triangles a little over 50% and obviously the more complicated the part the more triangles you'll need and some 3d printers like for example shapeways has a limitation on the number of triangles and the size of the file so so I'm not going to output that at this point there are a couple of other three-dimensional file formats that are fairly common one is IGS and one is step the only 3d printers that I've really seen take STL because that is a very easy to understand file format especially when it's an ASCII step and IG s are kind of more professionally type for formats so so now in terms of like drawings you don't select any of those you don't really need to you can you can actually turn this into a drawing and the way you do that is you simply go to file I think it's file make drawing from part so what that's going to do is you can select a template normally you would have just drawing I've drawn I've drawn my own template which has a little Creative Commons logo on it so I can hit okay and basically this is the sheet that you get and then you get to specify what view of drawing you want so you can select a 3d drawing or a top drawing so let's just drag a top drawing on here and then if you move the mouse around you can draw perpendicular versions so there is that and you can actually draw three-dimensional versions just to show what it would look like so I can click on that and that's all I want so I'm going to hit escape and there I have three versions three views this three-dimensional view is really only good for showing you what the final part is supposed to look like the other drawings the other views are good for actually manufacturing this thing so what you would do is you would dimension all of these things using the smart dimension tool you can just say you know there's that dimension there's that dimension there is that dimension and you're basically done aside from specifying your tolerances like plus or minus point zero zero one and aside from specifying the material and the type of finish you know whether it can be smooth or how rough it can be any machine shop should be able to take this drawing and turn this into an actual part so that's what would happen if you didn't go the 3d printing route with 3d printing you don't need this this drawing at all with 3d printing the file is enough but obviously if you want to see what the measurements are on the actual part you would use a drawing I'm not going to do drawings for this thing I'm just going to keep everything in solid works format so let me just go ahead and close this and not save it so there we go there is a washer so there's another washer so I'm simply going to open new make a new part okay so this washer is the really thin one that I found so what I'm going to do is again I'm going to start with a sketch on the top plane I'm going to start with the outer outline of the washer and let me measure that and the washer is point six two five all right which is nicely five eighths of an inch so I can simply say like for example five eighths and of course it'll compute point six two five so that's done now I will extrude it and the thin washer in this case is looks like point zero zero six you know point zero zero six point zero zero seven what's called point zero zero seven is fluctuating between those two so I'm going to oops cat my cat is is nudging my mouse button so I'm going to extrude this and I'm going to tell it that it's 0.07 inches blind okay that's pretty thin okay and now I'm going to look at the top okay and now I just need to sketch the inside select that face go grab a circle centered at the origin and now what I need to do is measure the inside diameter using my calipers and I get point three eighty six so I'm going to dimension that circle to 0.386 hit okay exit the sketch select that feature extruded cut and through all click yes and I can use alt to show you that that is our really thin washer so now I will simply save it as the thin washer so washer from bag 5 good enough for now so yeah so naming is so naming the files basically names the part itself so this part as far as solid works is concerned is called thin washer from bag 5 which could be a problem when I try to make an assembly and what an assembly is it's a special type of solid works drawing which sort of imports several other part files and then puts them together in relation to each other so you could say have a shaft and a washer and a screw and you can put the washer on the shaft and then you can put the screw on the shaft itself as well you can put gears on it you can put levers on it you can rotate the levers and so on but they're all in relation to each other the problem is that the the parts are all named after their file names essentially and if you want to rename those files you basically have to go into all the assemblies and rename those as well and there's there's actually I think a tool a free tool that you can download that actually does that for you which is quite convenient because it's extremely messy okay let's try another part this part is the standoff with it with a slot on one end and a threaded bit on the other so this will involve something slightly more complicated than a washer so I'm going to create a new part file okay and so I'm looking at it and it's basically a very long cylinder so we'll start out with a cylinder kind of like a washer I'm going to measure the outer diameter which has 0.252 yeah it's probably a quarter of an inch but I'll go with that actual measurement 0.252 so I will start a sketch on the top plane draw a circle snap the center to the origin and dimension it to 0.252 in diameter and exit the sketch now I will extrude it so how far do I extrude it well let me go ahead and measure of the length of the cylinder it says 1.215 1.216 1.215 all right so I will extrude it 1.215 inches blind okay now I can scroll using the scroll wheel so okay so that's what our part looks like right now so there it is now what we need to do is on the end we need to put the threaded bit now I said earlier that we don't actually put threads and parts because you know that would be like for example a it would just be an annotation on the diagram but the thing you have to know of course is the outer diameter of those threads so I'm just going to measure that okay now it says 0.137 now I know that these threads are of a certain measurement I think these are like number five something or other maybe I think they're 540s I think I decided and there is a a standard blank outer diameter that you would use and then you would you would use a die of the right threadedness to put your threads into but I'm just going to go with the outer diameter as I measure this so it says 0.137 inches so I'm going to look down at this part from the top okay that's the top I'm going to sketch on top of that select the face use a circle centered at the origin I'm going to smart dimension this to what did I say 0.134 I think 0.137 0.137 hit okay exit the sketch and now I will extrude that so let me just scroll out a little bit so by default it's choosing how much it was before but let me measure the size of the threaded portion and it says 0.315 so I'm simply going to say 0.315 blind and there we go hit okay and basically we've got our two pieces so basically this this standoff is two cylinders attached to each other again if you drew it you would you would draw one view like this and you would give the diameter of this section and you would give the diameter of this section and then you would give the length of this section and the length of this section and then of course the material the finish the tolerance so one thing that we haven't done at this point is put the slot at the end that's kind of an important feature to have because if you don't put a slot in there you're stuck with hand tightening this thing so to put a slot in the end basically means that you're going to kind of use a kind of like a cutting tool so let me rotate this so that we're looking at the bottom actually let me use the orientation so there is the bottom okay and what I like to do sometimes is just rotate it to make sure I'm looking at the right view that I want so what I want to do is draw a rectangle right across here and I want it to be of course bigger than the cylinder because it's going to act as a kind of a cutting tool and I'm going to sort of measure this a little bit by eye because I don't actually have any fueler gauges yet but I'm going to use the calipers which says that the slot is about 0.036 wide so what I'm going to do is I'm going to again sketch on this plane this time I'm going to choose the rectangle tool and there's a center rectangle so that's kind of convenient because I want the rectangle to be centered at the origin and then I'm going to bring it out past the ends okay now I have to dimension it so I take my smart dimension tool and I dimension this side which was supposed to be let me just measure it again 0.034 so let's say it's 0.034 okay now you notice that these sides here have turned black which means that they have been constrained completely so their distance is now specified these sides however are still in blue because I haven't specified how wide this is I've just said oh well it's wider than the circle so since I don't really care how wide it is I'm okay with how wide it is right now so I'm just going to take the smart dimension tool and say whatever length that is that's fine I don't really care so now I'm going to exit the sketch and now if I turn this around you can see that I've got a rectangle stuck to the end face and now as you can guess I'm going to select that sketch that sketch is selected and use an extruded cut and you can see that it's going in by a certain amount obviously I want it to go in by approximately the amount on the actual part which again I'm going to measure to be 0.05 so I'll say 0.05 and done and there we go we now have a cut we now have a slot cut at the end if you want to get rid of that sketch that's actually showing up what you can do is you can open this up and you can right-click and then you can select show show which actually turns it off so what it does okay apparently that really didn't do much did it okay alright yeah I don't know why that oh yeah it was because I had the sketch selected see if I have it selected now if I have it de-selected there I just have the origin selected now that's why that's showing up now I have nothing selected there we go so there's that part done so I will save it as for lack of a better term standoff from bag five okay so those are three parts that I've done I think that that's probably enough for now in bag five I've got a couple of screws which should be easy to model I've got a spring which we're going to we're going to model unfortunately springs are not actually solid parts because they do tend to flex and they can stretch so we'll learn how to do that we've got a gear so that's going to be interesting and then we've got some complicated lever type structure so we'll leave that for last so until next time I'm Rob thanks for watching and I'll see you next time I found my new love he's got the intellect yes he's got the mind of a great philosopher artist so sure of his place in history he's a mystery I saw him on TV he looks so handsome and he's in a new movie in which he really does all of his own
