FreeCAD Part Modeling Tutorial 65 _ FreeCAD Tutorial _ Mechnexus _

Hello friends welcome to free care tutorial and in this tutorial we will convert this

isometric drawing into the 3d model with the help of a part design workbench

so first we will make this base profile so for this we will create a new file then create a body

and create a sketch so we are going to select top plane and then I will draw a

rectangle and this rectangle is 82 by 140 so first I will make it symmetric so

I will select this point and this point and my axis and I will remove the

conflict now I will give the dimensions 82 and length 140

and we will also include this arc in our sketch so for this I will select this

three-point arc and create an arc and I will select this point and this axis and

make it a coincidence similarly I will also make it coincidence and I will

delete the conflict okay now I will trim this geometry ok so I will again give the dimension this point to this point 82 and let's see what

is unconstrained ok so we will give the radius I will make it horizontal and

this radius is of r18 so I will select the radius and give the 18 mm I will

also make it horizontal so our sketch is a fully constrained now we will extrude

it with the length of a 15 mm click on the pad and give here 15 let's say ok and now

am going to create this back side feature so for this I will select this face and create

a sketch I will rotate my view and

I will project this edge so if you see here here it is a 15 and it is a 28 so better I will project my bottom

edge in fact we have origin point so I will select a rectangle and create a rectangle

now I will select this point and line and make it coincidence total height is

of 54 so I will select this point and this point and I will give 54 and total thickness is 18 mm

So, I will select the sketch, click on the pad, I do not see my feature so I will make

it reverse and I will give here 18 mm and I will say OK

And now I will make this cut so I will select this face and create a sketch and I will project

my outer edge and I will select the three point arc and create an arc of R14

I will give the radius r14 and I will make this point and my origin point vertical and

I will make this point and this projected line with a coincidence constraint and I will

move my radius outside so that it should be visible now all I have to do to make this

profile closed and we are going to remove the material here so I will click on the pocket

and I will say true all now I will create this boss

so again I select this face and create on the sketch and I will project this arc

and I will select the three-point arc before that I will project these two

edges now I will select a three-point arc and create an arc and I will merge

this center so outer arc is r22 so I will select radius and give it r22 now I

will create an arc equal to my projected arc so I will select three point arc and

create an arc and in this case I will select these two arc and give equal

relation now I will close my profile this and this and I will switch to the

isometric and I will close my sketch and click on the pad so this pad is a 18 and

this is a 28 so 28 minus 18 is 10 mm so I will give here 10 mm so before that I

will cross check so this was the 18 my pad so that's okay now we are going to

create our next feature which will be this one and this will be the mirror

feature so I will select this face and create and sketch and from center it is

65 and the arc is r25 so I will project this edge and create a rectangle and I will delete this line and I will

select three-point arc and I will draw an arc and I will add the first

tangency relation to this I will uncheck it now I will select dimension

tool and I will select this point and my I want vertical dimension so I select

this and this it is a 65 so I will give the 65 now from the edge it is a 90 mm

so I will project this edge and I will select this and this and your horizontal

dimension of 90 mm and this radius is a 25 so I will select radius and give 25 so

we have fully constrained our profile now I will come out of the sketch and

click on the pad click on the reverse and the thickness is a 22 so I will do

here dimension 22 and I will say okay now we will mirror this feature so we

will select on the pad and click on the mirror and from here I will select

reference and I will select my mid plane and I will select on OK now I will

create these two because these two one here and one here so this is on the same

line of a 28 so again I select this face and create a sketch and I will project

geometry and I simply select a rectangle I will select this point and this point and

make it I will delete this and total height is a 28 from the base so I will select this

point and this point and give vertical dimension of 28. I will close it

so here I have projected this arc so that is not required so

I will delete this and I will delete this one and this line as well and I create line and close my profile and

I will make this line vertical. Now I will select this point and this point and click on merge and here I will remove

this conflict. Now I will close it so that is what exactly we want

Now this thickness is 12mm so I will click on the pad

I will give the 12mm and click on the reverse. I will say OK

Now I will mirror this. So I will select on the pad, click on the mirror

And I will click on select reference and I will select the mid plane So it got mirror on other side same way we will do here I will select the face and create a sketch

I will project the geometry which are required to create a rectangle and now I

will select rectangle tool and simply draw a rectangle and I will cue the

height this point to this point vertical height of 28 I will close it and I will

click on the pad reverse and this is also 12 mm say ok now let's select on the

pad and repeat the same procedure I will select my reference you can select axis

or select your reference I would prefer to select my own reference so I will

select this mid plane and you can see that it is mirror on the other side now

we will create these two hole so I will select the face and create a sketch so

this is of diameter 28 so I will project this arc and create a circle of

for 28 give the dimension now I will close it and I will simply create on the

pocket tool and from here I will select up to face and I will rotate my model

and select this face on the other side say ok now we will create this hole of

diameter 22 so I will select the face create a sketch and we will repeat the

same procedure as we did earlier now I select a rectangle and give the diameter 22

okay now I will close it and I will click on the pocket tool and from here

drop down I will select true all and say okay so you can see that how we have

successfully converted this isometric drawing into the 3d model so do not

consider this ages which you are seeing if we go to the shaded view so we can

see that it is a single body so I will on the flat lines and now we can use some

color to our part go to the princess and you can select your own shape color you

can give any color of your choice you can also visit my website macnexus.com

where I write articles and tutorials on a free cat you can also download my

tutorial source frame from the here you can also support my work by buying my

free CAD crash course for beginner it is a very basic level course for the

beginner user where a beginner user can master the free CAD and you can also

support my work on coffee.com you can buy me a cup of coffee you will get my

website link and my Ko-Fi donation page link in a video description but I would

prefer to do Chrome. So this is how to model this

isometric drawing into the 3D model with the help of a part design workbench and

I will provide this 2D drawing and this 3D model in a video description so you can

download my source file and practice accordingly
