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
