  • from time to time you probably run into a picture something that you want a

  • model in this case i found a one handed

  • beer bottle opener and so many use this sketch picture inside

  • of solidworks to recreate this design so to start i want to create a new part

  • and have a part metric template if you don't have a template in metric

  • units you can come to the options go to document

  • properties and change the units

  • so I'll create sketch on the front plane and over the tools

  • sketch tools and sketch picture and I save this over the desktop

  • i may go ahead and bring it so you can modify this by using the

  • properties on the left which generally easiest way

  • to work with this is simply dragging it out

  • and resizing it in the workspace i want to create a quick reference line

  • for one of my dimensions so i can get the sketch picture dimension correctly

  • typically any picture you find a minute isn't gonna be the size that you want to

  • be so easiest

  • way to go is typically draw out a couple reference lines

  • and give them a dimension and then get your picture set

  • in this case i took a quick trip with my fridge

  • grabbed a beer and a pair of calipers

  • and got the width of the beer bottle cap

  • so Im gonna go ahead and add a quick centerline with the width of twenty eight point five

  • millimeters you can see the pictures quite a bit

  • larger than my reference line

  • so I'm gonna go ahead and resize it by double clicking back in

  • until we get down to the correct size

  • in this case since it is a bottle opener

  • we quite prefer it to be slightly oversized than being a slightly

  • undersized that looks about right

  • and i no longer need this centerline so I go ahead and delete it out

  • next i wanna grab my line tool and start tracing

  • this bottle opener out as well as the circle tool

  • this looks like a simplest way to start so go ahead and add a circle

  • and I'm gonna go ahead and make this twenty six

  • millimeters

  • once i have the circle i can see that it's undefined or under

  • defined and that might make it a little bit

  • difficult to work with this entire profile as I created

  • i want at least one good base where i don't have the entire

  • sketch moving around so I may go ahead and right click in

  • and go to fully define sketch and click calculate

  • and this will just add two positional dimensions from the origin to the center

  • of that circle next I'm gonna go ahead and create another

  • circle and give that another dimension

  • there's some items that you work with their some pictures you work with with

  • the dimensions are very important

  • in this case as long as it is roughly close

  • that should fairly easily open a bottle of beer

  • from here I'm gonna grab the line tool and start tracing the rest of the profile

  • I go ahead and click this in and if I press A

  • this will bring me into a tangent arc

  • and once i click again this will bring me back in the line tool

  • click once more hit A again

  • and that will bring me back into the tangent arc

  • and once again and once again

  • now just continue around and get the rough profile

  • so you can see a half most of the tangent relations i need

  • but we want to go ahead and make the other arc tangent as well

  • so control click in for those selecting both

  • and making each of these tangent where they need to be tangent

  • from here i can start adding dimensions once i have certain

  • radius set I'm gonna go ahead and add

  • each one of these individually so this back arc looks pretty good

  • so go ahead and give it its radius lets call it eight and half millimeters

  • the top looks good as well and so this doesn't move around too much

  • while dimensioning this I may go ahead and add a couple

  • of dimensions and as you had dimensions you can

  • notice that this will project in whatever direction it

  • thinks that you want to dimension it

  • and if you wanna lock this into a certain dimension

  • you can simply right click see next to my mouse there's a little lock icon

  • and now I can place this where i want

  • so i can go ahead and continue dragging this out

  • I go ahead and drag a centerline from the origin

  • and my angle looks just about right

  • on the side of this line I'm gonna go ahead and create an angle

  • dimension and the final line

  • next I go ahead and set this radius once i had it in the right place

  • and i noticed a horizontal relation accidentally got added so I can go ahead and

  • delete that out so i get the correct angle here

  • and I can continue refining this but this looks about right

  • so I'm gonna go ahead and just right click in once again and see it in fully defined

  • sketch and this isn't always the best tool to

  • use as little dimension has it

  • sees fit but it's typically very convenient once you

  • have everything set in the sketch and with that last change this looks

  • about right i want to have a single close profile

  • so its easier to look through so I may use the trim tool

  • with the power trim option and I left click drag into this line

  • to remove out that extra arc and once i have all that set i can

  • simply use the extrude tool I may choose the mid plane option

  • and ten millimeters looks about right

  • so go ahead and click ok and here we have a completed key beer bottle

  • opener
