Hello friends welcome to freeCAD tutorial and in this tutorial we will learn how we can hollow out a solid in freeCAD
0:08
So here I have launched my freeCAD and I will create a new file and I insert my body on my origin planes
0:21
and I select this top plane and create a sketch and now we will create a very
0:28
simple profile select the rectangle and I will create a rectangle and give it a
0:39
dimension of 100 mm and this one also 100 and next I will create a line by
0:54
joining this to horizontal and vertical line use the trim tool and I will trim
1:00
Now I will give this horizontal dimension of 50 mm. Select this and this and make it equal Now I will close it select the sketch and click on the pad
1:27
and here I given the 100mm length now say okay so we have a very simple part and we will learn how we can hollow it
1:36
so here on a part design workbench you will see option called thickness so click on this options so you will see
1:49
the properties of thickness parameter like the thickness mode and joint type
1:57
let's first I you my thickness to the 2 mm and from here click on the select
2:06
select this face so you can see that a face is selected now I will say okay now
2:16
you can see that our part is hollowed and here fillet has been also added so
2:25
we will learn how we can customize this hollow what if if you do not want this fill it so for this we will go to the edit thickness and here on a mode type we will keep the skin and here on the joint type we will select the
2:44
intersection so when we select the intersections then this face and this face having the
2:51
intersecting line but if we select the arc then it will automatically add the
2:58
fillet to the all the corners so this is how we can change our joint type and say
3:08
ok now let's select the multiple faces to hollow out for example I do not want
3:17
this top face so I will go to the edit thickness and here on the select option I will select it
3:25
and I will select the top face and say ok so you can see that top face also got hollow out
3:33
go to the edit thickness change the type to the intersections so you can see that
3:41
sharp edges has been created between the joining faces and let add one more face to our hollow out sections say click
3:57
OK edit thickness and click on the select let's select this face and say
4:05
OK so this is how we can hollow out a solid in free CAD with the help of a
