How to Draw an Elbow Pipe with Flanges Using FreeCAD

[Music] hello everybody i hope you had a good week today we are going to go through a free card tutorial on how to create an elbow pipe so let's go ahead and get started change your workbench to part design go ahead and click on create new click on create body click on create sketch go ahead and click on x y plane and then click on ok go ahead and click on the line tool and then draw a straight line and then draw another vertical line let's go ahead and give a horizontal and vertical string to these two lines uh click on the horizontal line give it 200 let's zoom out go ahead and click on the vertical constraint click on the vertical line and give it 200. okay and then let's go ahead and create a a fillet between those two lines click on the fillet tool click on the first line click on the second line go ahead and click on the constraint which is the radius constraint and give it 100. okay let's zoom out so what we're going to do is we're also going to give it uh this drawing uh a constraint so it's fully constrained so go ahead and click on the vertical constraint tool click on that point and click on that point and then give it a distance of 100 right so let's go ahead and check that so that's 100 that's a hundred so again let's check that costume okay let's give this again the question it looks like do i taken out let's go ahead and select our vertical constraint put it on that line and give it 200 select our horizontal constraint click on that line and give it 200. yeah i think there's an issue with a free card here since we did a fillet it actually chopped off a part of the patch so it's better to do the fillet first and then pro do the distances so our object is uh fully constrained as you can see let's just move other so everything is okay go ahead and click on clause there we go we have our outline so we are going to create another sketch click on create sketch this time we are going to select our uh yz plane okay so click on yz plane click on ok so after clicking on ok we shall get our coordinate system we are going to draw a circle click on the circle tool on that point then click out go ahead and click on the radius constraint you're going to click on that circle and give it a radius of 50. let's zoom out okay i think that's okay i'll go ahead and click on close so we have our circle and also we have the outline of our pipe so what we're going to do is we're going to go ahead and click on on [Music] this tool uh which is the sweep tool or you can call it an additive type so go ahead and click on this tool so and then on that tool it's going to let's first close this just to be sure let's go to the model uh make sure we're clicking on sketch one because we need the circle click on sketch one click on that uh additive tool or sweep tool it will ask for the path go ahead and click on object and click on that path and then it will give us the outline of our pipe go ahead and click on ok as you can see we have the outline of our pipe so click on that face click on control click on that second face and then click on this tool which is uh make a thick solid go ahead and click on that it will ask for the dimensions set the dimensions to 5 and then click on ok as you can see if we check through you'll see that our pipe is now hollow uh so that part of the pipe is done so we're going to go ahead and uh and draw the flange on both ends so zoom in to this make sure you select that inner edge like that and then you're going to click on this tool which is local coordinate click on that uh click on selecting and then click on ok right and then click refresh so go ahead and click on this first and then click on our new data plane tool uh click on that and then click on ok go ahead and refresh then click on the data plane tool click on sketch and zoom in click the sucker tool click that point draw the faco click that point draw the second circle let's go to constraints and select the radius cost strain click on the inner circle and give it 50 millimeters that will match with that inner section okay then click on radius constraint again click on the outer part of it and give it 90. so we are done with our two dimensions and they are fully constrained go ahead and click on close make sure you're selecting sketch tool and then click on the pocket tool under pocket tool sorry this is not uh it's not supposed to be a pocket click on sketch and then click on the pad tool and a pad uh give it a 10 millimeters okay as you can see it will fit there so give it 10 millimeters and then click on okay okay uh we should be good with that so go ahead and click on our datum tool again uh click on sketch zoom in uh we're going to draw our circle again so if you don't see the lines you can always click on this tool so the lines come on top click on that make sure you're selecting that line and draw the circle go to radius constraint give that circle 8 press enter go to vertical constraint sorry horizontal constraint click on that point and then click on the center of that circle and we're going to give it around 17 i should put it in the uh roughly in the middle yeah servant i would be fine so after we do that go ahead and click on close uh click on sketch 3 click on pocket we are going to change this to to fast and then click on reverse and then click on ok click on pocket click on polar array change this or currency to 8 and click ok so that is the first side of our uh pipe done so we are done with drawing the flange of the pipe on one side everything is fine as you can see so let's go ahead and draw the second side go ahead and click that second line uh click on create local coordinate click on selecting click on ok refresh click on that first click on create the template click on ok click on refresh go ahead and click on our data and click on sketch so let's zoom out let's do this hold on we need to make a change it's not coming it's not coming out as i wanted let's first uh delete that delete that and delete that we're going to draw that datum again so let's make sure we are selecting that in a line click on create local coordinate system click on selecting click ok refresh uh click that line again click on create new data right click ok click refresh okay then let's go ahead and create uh click on that first and create a new sketch okay so let me zoom this in so once you create that new sketch you can see that our coordinate system has moved from down here uh back to up here so let's go ahead and draw that uh click on the soccer tool click on that center draw the first circle click on that center draw the second circle let's go to the radius cost string click on the first one give it 50 click on the second one give it 90 and we are fully constrained on that okay so let's go ahead and click on close make sure you're selecting sketch4 okay so once we have sketch 4 uh go ahead and click on pad we're going to give it 10 click ok so let's check everything seems to be good now we can hide these datums since we can hold on we can hide these the terms by selecting the term and pressing the spacebar even that so we have our image clear so as you can see we are done with that so we are going to go ahead and uh draw the holes so select that datum uh click on sketch again so we can see our flange so we're going to draw the holes here click on that tool click on the circle tool draw the circle there go to constraints select radius constraint click on that circle give it eight click on horizontal constraint click on that spot click on that spot we had the other one at 70. so we have to make it uniform right so after you have that go ahead and click on close let's click on our sketch 5 click on our pocket tool remember we are saying this is uh reversed and to first so our whole can go through and then click ok click on the pocket click on the array change the occurrence to 8 and click ok and there we go we can now remove uh just hide the local coordinate systems on that even that and there we go we have our elbow pipe or you can call it an elbow joint with flange to to be able to connect two pipes at a 90 degree angle so as you can see everything is fully constrained wrong and complete okay that's it have a good week [Music] you
