Please find below the drawing :

Kindly please try and explain the process followed, i.e. the dimensions made before applying fillet radius.

 

Thanks,

Vishu

Draw the horizontal line first then the vertical line. Next measure back from the left 32 and draw a line from that point on the 240 angle to get the diagonal line. Use offset from your lines to get the thicken of the pipe, by offsetting lines half the width of the pipe each direction from the center line. Delete center line now as you don't need it. Now put in all the fillets. To figure out the inside fillet when they give you the outside radius, just subtract the width of pipe from the radius and use that number as the inside fillet radius. It's addition when you have the inside fillet radius and you need the outside one.

Hi @Anonymous,

 

Are you asking how to draw all of this in 2D or 3D? I see a section mark on the left side that makes me think you are trying to do this in 3D?

 

Or, are you asking a specific question on just one part such as a radius or fillet?

HI @Anonymous,

 

I didn't get answers from you so I have made some assumptions.

 

First I drew two horiz. (parallel lines 5 mm apart) and made them 327 mm longCapture1.PNG

Then, from the right hand side I offset 32 mm to the left.I trimmed the horizontal lines to this length. I also offset the right hand vertical line 5mm to the left

Capture2.PNG

From the rt hand end of the horizontal lines I drew lines at 120 degress and then did a fillet with radius of 4mm for the top. I offset the arc down 5mm and trimmed the lines.

Capture3.PNG

Next, I filleted the top angled line with the rt hand vertical line with a radius of 12 (and then again at 5mm

Capture4.PNG

 

This should give you the basic shape.

I think you will need to do the Filleting on some starting-assumption linework, and then adjust certain dimensions from the results.  That may be the only way to get the endpoints of the curves to be in the correct positions.

 

One thing the diagram does not seem to show is the pipe diameterIf  the inside radius at the longer/upper curve is 4.0 as at the shorter/lower curve, then the pipe diameter would be 8.0 [rather different from @john.vellek's assumption of 5].  Is that a realistic assumption?

 

[I also find it very peculiar that they would dimension the angled portion at 240 degrees swinging all the way around like that, rather than at the more-obvious 60-degree acute angle.  This doesn't seem like a very good textbook, if that's where this comes from.]

Please can you tell me what it is the total length of this rod ? That is how to straight the bend.

 

And what way are you using to calculate this. Is there any method to straight the bend section to find the total length/

Question for you.  You set from the right end of the first line, 327, 32 units and then used that point for the left most end of the 4 R units arc.

 

That off set is in reality 32 + the diameter, width, or thickness of the item?

 

There is no proof in the picture of the item as to its shape.  That could be the side view of a 3 x 34567 wide flat plate with a couple of dados across it for all we know.

 

I contend that insufficient information is available to correctly draw the item and without the A-A profile it can't be done except by the guess method.

 

Could you enlighten me?

 

Thanks

 

Dave

Can't believe no one mentioned using multi-line to draw this if a 2D solution was required!

 

Using multi-line there is no need for all that offsetting!

 

I'm just saying!

Please note that the original drawing lacked some information and due to this, assumptions were made. You have not confirmed the assumptions as correct or provide corrected information. The video was created showing a method (based on assumptions) to draw the part. We didn't even have information as to whether that the part was round or flat.

 

As for the total length of the rod (part now verified as being "round"), you could and should Goggle 'Bend Allowance' and figure the length out yourself because:

1. We still do not have confirmation regarding the missing information/dimensions (diameters, metric or imperial units, and now material ) - so a "length" would once more be based on assumptions.

2. If this is a class assignment you need to learn how to do it for yourself - it may be on the next test.

3. If this is a work assignment you need to learn how to do it for yourself - you may have a similar problem in the future.

MLINEs can't have arc segments.  You could use one to establish an overall first-assumption route with a horizontal leg, 60-degree leg and downward leg, but then you'd have to Explode it to Fillet the corners, and then make adjustments of positions to get the desired dimensional relationships.
